Hello.
I have a networking problem that seems to have gradually made its way to the point of utter annoyance and seems to be due to our router. Our small business of 7 computers and growing is networked via wired Ethernet, our ISP is a cable based provider (Shaw), Modem: Motorolla 5B 5100. For several months now since the introduction of two pre made HP windows 10 desktop machines our network has started to act erratically. Computers are disappearing when viewing them under networking in Windows7 and 10.. They spontaneously reappear throughout the day. Our full network map is different from each computer. The strange thing is that the computers are there. I saved shortcuts to each shared folder and placed them on each computer and they are accessible consistently, but the computers pop in an d out of existence when viewing them under the network view and aren’t accessible that way. There is no interruption or slow down in access to the internet. WIFI is unaffected. This problem only affects local networking views.
Please see the attached picture of our network http://s44.photobucket.com/user/westwoodmemorials01/media/Troubleshooting/computer%20issues/westwood%20network%20map%2011.12.2015_zpsw2yfvyt5.jpg.html (http://s44.photobucket.com/user/westwoodmemorials01/media/Troubleshooting/computer%20issues/westwood%20network%20map%2011.12.2015_zpsw2yfvyt5.jpg.html). This big "?" you see in the picture comes and goes and varies when you view the network from the other computers.
Our machines are all windows7 home premium, a mix of 32 and 64 bit and now window10 home 64bit. 3 have Kaspersky virus protection (purchased) , the others have Avira free. The problem does not seem to be specific with any of the machines running a certain virus protection. We are not using windows Homegroup. Our advance sharing/network discovery is enabled on all the computers share the same settings throughout; see here http://s44.photobucket.com/user/westwoodmemorials01/media/Troubleshooting/computer%20issues/advance%20network%20settings_zps9cdtyikr.jpg.html (http://s44.photobucket.com/user/westwoodmemorials01/media/Troubleshooting/computer%20issues/advance%20network%20settings_zps9cdtyikr.jpg.html).
Months before I have noticed the the network taking a long time to show files on one computer or the other but just brushed that off. You can see a video here https://youtu.be/V9ZBkYo0WPc (https://youtu.be/V9ZBkYo0WPc) to see how slow it takes for an F5 refresh to show our network. So I don’t think this is entirely related to the two new windows 10 pcs. Our network and firewall setting shave been untouched for years now. Cycling the router off back to on though makes makes a big difference as once you do that all the computers are now visible for a couple days but then gradually begin to disappear. Incidentally, after these router restarts the windows 10 machines no longer see anyone under the network, BUT network shortcuts STILL work. So whats going on with our router? Its barely a year old!
You can view all our hardware in the above mentioned pictures or Listed below:
Modem: Motorolla 5B 5100
Router: Dlink DIR 826L Hardware version A1, Firmware version 1.02 region: Canada
Switches: Netgear FS 116 ProSafe 16 port 10/100
Any help would be appreciated, never had this problem before.

Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router. Be sure to log into the Admin account on the router.
- Turn off TrueGigaBit Routing (http://forums.dlink.com/index.php?topic=60699.0) under Setup/Internet/Manual for those routers that have this feature for testing.
- Setup DHCP (http://forums.dlink.com/index.php?topic=58017.0) reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
- Ensure devices are set to auto obtain an IP address.
- If IPv6 (http://en.wikipedia.org/wiki/Ipv6) is an option on the router, select Local Connection Only under Setup/IPv6.
- Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI (http://en.wikipedia.org/wiki/SPI) to test.
- Enable uPnP (http://en.wikipedia.org/wiki/Upnp) and Multi-cast Streaming (http://en.wikipedia.org/wiki/Multicast) under Advanced/Networking. Disable uPnP for testing Port Forwarding (http://forums.dlink.com/index.php?topic=4235.0) rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.
- Turn off WISH (http://forums.dlink.com/index.php?topic=40459.0), and WPS under Advanced.
Test with the PCs directly connected to the router. The Switches you have are 100Mb max speed connection rates, the router supports up to 1000Mb and I presume that you newer PCs support 1000Mb on there network adapter cards as well.

Hey Thank you very much for the response. I read through your response and am trying to implement the changes but have to admit I'm a bit lost with where to find some settings.
"Turn off TrueGigaBit Routing under Setup/Internet/Manual for those routers that have this feature for testing."
I turned off this option and several minutes later, lost my connection to the router, network and internet. I had to physically restart the router to regain access to the network and internet. The computers that are visible on the network are now different from each computer station which is kind of going back to what problems we're having before. Should I re-enable this option?
"Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking."
should I follow the DHCP link you provided using the step for "Reserved IP addresses" I am basically adding a DHCP reservation address for each computer on our network? If I follow through and enable this option will I have problems adding another computer to the ethernet network in the future? Do I also have to do this to devices that connect WIRELESS to our network, like apple and android phone?
"Ensure devices are set to auto obtain an IP address."
where is this option found? On the router or in each computer?
In another website, I was told to go to my network connections, right click on the local area connection properties and turn off TCP/IPv6 on all our computers. Should I go and enable this again on all the machines before proceeding further below?
"If IPv6 is an option on the router, select Local Connection Only under Setup/IPv6."
on the DIR 826L, there are 3 options under Setup/IPv6:
1.IPv6 Internet Connection Setup Wizard
2.Manual IPv6 Local Connectivity Setup
3.Manual IPv6 Internet Connection Setup
I should choose #2? The only thing I can tick of there is to "Enable ULA" I should do so? If enabled the only other options are
Use default ULA prefix :on
ULA Prefix: /64 (currently filled in with a 15 digit alpha numeric string)
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall."
I have no such option under Advanced/Firewall settings. The only thing I can do is enable SPI. Should I do so and leave it on all the time?
"Enable uPnP and Multi-cast Streaming..." you mean under Advance/Advanced Network? I Should enable IPv6 (its currently off)
"Turn off WISH, and WPS under Advanced." I cannot find this simply under Advanced. Is this under Advanced/Wireless? or under Setup./Wirless?
If you could please clarify that would be great. I'm a real novice at this stuff.
I really dont under stand why this is happening. Should I update the routers firmware? Thanks.

When this feature is disabled or enabled, the full reboot of the router and PCs should be performed and is expected behavior for this feature.

Yes If I follow through and enable this option will I have problems adding another computer to the ethernet network in the future? No Do I also have to do this to devices that connect WIRELESS to our network, like apple and android phone? If they are commonly connected to the router then yes. If they are only have temporary connections or connected once, then you don't have to.
"Ensure devices are set to auto obtain an IP address."
where is this option found? On the router or in each computer? Each computer. Control Panel => Network and Internet => Network Connections
Right click the "Local Area Connection" you want and select "Properties" and then click the "Configure" button. Select the IPv4 Protocol listing.
In another website, I was told to go to my network connections, right click on the local area connection properties and turn off TCP/IPv6 on all our computers. Should I go and enable this again on all the machines before proceeding further below? If you don't have a need or a requirement on your network or you ISP services doesn't support IPv6 on there service, keep IPv6 disabled or let to Local Only Connection.

"Enable uPnP and Multi-cast Streaming..." you mean under Advance/Advanced Network? I Should enable IPv6 (its currently off). Keep disabled only if you don't use IPv6.
"Turn off WISH, and WPS under Advanced." I cannot find this simply under Advanced. Is this under Advanced/Wireless? or under Setup./Wirless? WISH may not be a feature on this model router, so you can skip it. WPS will be under Advanced/Advanced Wireless I believe.
If you could please clarify that would be great. I'm a real novice at this stuff.
I really dont under stand why this is happening. Should I update the routers firmware? Lets see if the current FW can be configured to work for you first.

First, can you still ping the computers by IP when they "disappear"? Depending on your DHCP lease length, it may be having a hard time resolving the domain names to their IP.
Second, are the two Windows 10 machines have up to date NIC drivers?
Third, have you tried disabling file sharing and see if that makes network discovery faster? Also, try 40-56bit encryption, in case of compatibility issues. These would just be temporary measures to isolate the issue.
Last, it is odd to see a consumer router mixed in with 2 16port smart switches. Why do you have two if you only have 7 PC's? Why not just use one with a VLAN?

Any status on this? ???

Sorry for the late reply. Our business got busy for a bit and I didn't want to muck with the network at the same time.
"Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking."
If they are commonly connected to the router then yes. If they are only have temporary connections or connected once, then you don't have to.
This ended up being very difficult to do. some of the computers would not show up on the list. I had to keep re-logging back into the router at different times. One of the windows10 machines, "Crystal" was renamed as "Workgroup"under the Dynamic DHCP clients. you can see that evident here: http://i44.photobucket.com/albums/f37/westwoodmemorials01/Troubleshooting/computer%20issues/dlink%20network%20DHCP2email_zpsmgflulxg.jpg (http://i44.photobucket.com/albums/f37/westwoodmemorials01/Troubleshooting/computer%20issues/dlink%20network%20DHCP2email_zpsmgflulxg.jpg)
I dont know why "Cystal" is listed as "Workgroup" and this was the only pc that had this problem.
"Ensure devices are set to auto obtain an IP address."

after doing all the changes and rebooting the router. mostly all the computers showed up in every one else's network tab. Only the windows10 machines were absent. the network settings are still unstable though. I did that Friday. Today 1st thing after coming into work, I cycled the router on and off. All the computers saw everybody uniformly under network tab. The only hold out was the "Crystal" windows10 machine. BUT as the day moved on the network degenerated. computers started disappearing again. So its basically like a full reboot of the router makes everyone see everyone else and even the network runs faster, ie. accessing someone elses shared folder shows up more quickly. but as the day goes on computers disappear. whats even more problematic, rebooting a machine will make it all the computers disappear and only see part of the network again.
is my router going bad?

Do all PCs have there workgroup name set? This should be set for each PC as this will help the router detect and identify the name in the Dyanmic Clients section on the router. If there is not host name set, then the router will only display unknown or nothing. If the Windows 10 PC displays workgroup then something in Windows 10 needs to be changed.

Can you turn OFF the windows 10 PC and see if you notice any different behavior? Im wondering of this PC maybe causing problems.

Hi.
After many weeks None of the suggested changes have affected the network view of the 7 diff computers. Rebooting the router USED to make every machine show up nicely but i've noticed now that even on router reboot, the machines do not want to show up anymore. So it seems like the router is degrading?? I've also notice that surfing the internet wireless on an android phone sometimes is very laggy, taking very long pauses to load a webpage. I'm not sure if this is the same on an iphone or laptop using the wireless network. Ethernet surfing on the computers seems to be consistent throughout.
My 'network location' varies from one computer to the next. It changes from "network3" to "network4" could this possibly be causing problems? Though one network location does not consistently show up better than another. For instance the computer named "Central-PC" which is on network location "network3," you can consistently see ALL the other computers under network view but "Crystal-PC" which is also on network location "network3" cannot see all other machines.
Do all PCs have there workgroup name set? This should be set for each PC as this will help the router detect and identify the name in the Dyanmic Clients section on the router.
I've left all PCs with the generic workgroup name "WORKGROUP". Should I change this from the generic "WORKGROUP" to something else like "WESTWOOD" or something?
If there is not host name set, then the router will only display unknown or nothing. If the Windows 10 PC displays workgroup then something in Windows 10 needs to be changed.
So is this why the one computer "Curtis-PC" can never display its connection to the router under the 'show full network map" option and rather shows a "?" see here:
http://s44.photobucket.com/user/westwoodmemorials01/media/Troubleshooting/computer%20issues/westwood%20network%20map%2011.12.2015_zpsw2yfvyt5.jpg.html
The windows10 pcs have the workgroup name set to "WORKGROUP" as with all the other PCs.
You might give a FW update a try and see how it goes.
I will start reading up on how to do the FW upgrade. It HAS to be done with a computer directly connected via ethernet to the router? I should disconnect all other ethernet cables?
Can you turn OFF the windows 10 PC and see if you notice any different behavior? Im wondering of this PC maybe causing problems.
Turning off the window10 PCs doesn't not have any positive affect on being able to view other PCs on the network.

WORKGROUP should work however it's recommended to change the group name to something less generic and more identifiable.
Always update FW using a WIRED LAN cable connection. You can leave the PCs connected however I like to disconnect all from the router to ensure a good clean installation of FW> Please follow the FW Update process link.
I guess I'll connect up my 826L this evening and see what I find on mine.

Thanks for keeping on top of this thread. YOu've been very helpful. Please see the top of reply #9 as I've added some additional information while you replied already regarding network location names.

I have installed my 826L last nite and is online. I haven't had a chance to do more then that.
If your seeing network location messages or information that is changing, usually means there is something happening on the network or something is changing as I presume you maybe seeing networking popups when you first log in to the desktop? Are you seeing please select a network location, public, work or private?
I'll be looking at my networking this evening and see what I find.

Hi there
never had a pop up for our networking location since the computer were 1st hooked up years ago. All our network location are set to "Work."
I've also changed all the computers workgroup names from "WORKGROUP" to "WESTWOOD"; no change in network behavior.
I did a router upgrade, going from 1.02 tp the most recent 1.06. Left all the settings at default did not re upload the old config file but manually retyped all settings for ssid, wifi etc. All other settings were left default.
At 1st, this was success, I could see everyone showing up in network places EXCEPT both windows 10 machines. That was in the morning of monday. By the end of the day I noticed the computers were disappearing. The next day and onward we're back to square one. Almost every computer is seeing no one (including itself) when looking under network locations. Should I apply the settings you had specified earlier again? they did not held with the network views previously.
Is it possible to change "Network location?" currently all the machines are either set to "Network 4" or "Network 3". There is no positive correlation between a computer being on Network 3 or Network 4 but who knows, it might help?
Should I use windows7 HOMEGROUP? I dont really see much benefit from using them. I dont know anyone who does either.
Is this router faulty?

Have you set up IP reservations for ALL PCs on the router?
Also is the routers LOCAL LAN name set to WESTWOOD as well?
-
why do you have so many discovered devices that "can not be placed" at the bottom, or are they just turned off?

Have you set up IP reservations for ALL PCs on the router?
have not done so yet. Will do that later when the network isn't being used as much. Should I also follow you're previous posts for turning off gigabit and IPV6 protocols?
Also is the routers LOCAL LAN name set to WESTWOOD as well?
Are you talking about under setup/network settings you have boxes for Router IP address, subnet mask, device name, Local Domain Name? I should set this to "WESTWOOD"?
-
Yes lets try both configurations and see.
Might disable the IPv6 protocol with in the networking on each PC as well.

Any status on this? ???

thanks for keeping tabs.
unfortunately no improvements in the situation. all above suggestions have not made a difference. I just finished reinstalling windows on one of the machines and even with a fresh OS, I cannot see most of the computers on the network. I've done DHCP reservation for this new computer and along with the older ones and nothing has changed. Currently the only two machines that are visible from almost everyone are the two windows10 machines "Crystal" and "Workstation03". "Central-Pc" is the anomaly and see's everyone day in and day out. It is a windows7 machine and I don't know what magic it has but it's been flawless on the network being able to see everyone else.
This has been nothing but frustrating. I had to re-install drivers for industrial CNC machines which require access to files on computers over the network. It was nearly impossible to do so with the router acting the way it is. I was only able to get it done by rebooting the router numerous times and saving shortcuts to the folders when they are visible on the network, which then disappear over time. This is not good for CNC cutting machines that a running jobs that require consistent access to files to run.
Can I RMA or request a replacement for this router??I really had high hopes for it.
Any status on this? ???

What Windows 10 version are you running?
How is the profile set up with in 10? Stadnard, Private? All Networking? Admin?
How do you have your Windows networking configured? Home or Work?
Check in the Networking and Sharing Center...

I booted to my Windows 10 drive last nite. I have Pro which is what I got when I selected the upgrade option in Windows 7 which was Ultimate at the time.
I looked at the settings in 10 and saw Private however I did have network discovery selected. I could see my other two Windows 7 PCs and my NAS listed in Networking.
However I need to install my 826L and retest again. The router I currently have on is a DIR-880L. I'll try and recheck this evening with the 826L.

What Windows 10 version are you running?
windows10 home edition 64bit
How is the profile set up with in 10? Stadnard, Private? All Networking? Admin?
not sure what you mean. Account profile? Its set up as local account administrator.
How do you have your Windows networking configured? Home or Work?
Check in the Networking and Sharing Center...
windows10 did not give me that option. Its configured as a 'private network' under network and sharing in windows10. Not sure how to change that as its not giving me a clickable option. It does allow me to join a home group which none of the computer are on

These are for Windows 7...
I rebooted the router this past thursday (turned it off and on again) after 20second count. All the computers were able to see one another under network view right away. After a 3day weekend, the network looks constant. All computers are still able to see one another after a full work day. Seems like turning the router off and on fixes the problem so does that mean there's something going on with the router?

were you able to do the below investigation? I don't see how changing setting on one or more windows machines would affect other machine views over the network. Turning the router on and off seems to make the biggest change in terms of improving network visibility.
I booted to my Windows 10 drive last nite. I have Pro which is what I got when I selected the upgrade option in Windows 7 which was Ultimate at the time.
I looked at the settings in 10 and saw Private however I did have network discovery selected. I could see my other two Windows 7 PCs and my NAS listed in Networking.
However I need to install my 826L and retest again. The router I currently have on is a DIR-880L. I'll try and recheck this evening with the 826L.
-
So after doing a power cycled of the router the PCs can see each other and can access shared resources?
I have not had a chance to test the 826L yet. I'll test again if you need me to.
I'm wondering if something on your network may have been causing a conflict in IP addressing maybe or hanging up the router. This may cause some networking issues. I have seen this before if devices are in some form of conflict they wont appear correctly.
See how it goes this week and let us know by this weekend if anything happens.

This still working? ???

Hi
Unfortunately no. Up to last Wednesday the network started to degenerate again. A power failure in the building shut down everything for an hour.
when the power came back up, the network was fine but by the end of the day, computers started to disappear again.
As of monday, power cycling the router did nothing to improve the network visibility. most computers are not showing currently aside from the computer named CENTRAL which is a windows 7 machine and has been rock solid (Can see every computer on the network always; I don't know what magic is in it).
Now I'm noticing that network refresh rates for files are really slow as has happened in the [past when this router was at its worst. . BMP files that are accessible over network folder from a window 7 machine are taking very long to update and even eventually not having their previews updated

here the usual degraded network view.

is their anything else I can try? How do i put the router on a schedule to power cycle every nite? would this help? Is this an indication the router is failing? This problem is affecting our ability to point industrial machines to shared files/folders over the network since it cant view the network folders.

I presume that you mentioned that the router was working before the introduction of Windows 10?
Can you draw us a diagram of how your network HW is all connected? Please include any switches and what maybe connected to them as well.
ISP Modem>Router>Any network switches>connected devices to switch.
>LAN connected devices to router.
If you power cycled the router and the problem didn't go away, I presume that power cycling the router on a scheduled basis may not work and honestly, most routers should not need to be power cycled if all is configured and set up well.
Are all devices set up for a Reserved IP address with in the routers DHCP IP address pool currently? We can try some static IPs out side the pool.

power cycling sometimes doesn't work. Seems like its touch and go.

How do you try static IP's outside of the pool?
Does this router seem defective? I have a two year warranty, I think I would like to get another but I don't know if the problem would occur again. I also do not know how the place I bought it would test this and duplicate these errors. At it's core, the router seems to be working. WIFI is solid. Only thing is longstanding computers do not show up under network places over time. I'm not sure they can replicate this error. Also, network transfers and database queries have been very slow for the longest time now. Sometimes with power cycling things go very fast initially, but it seems to degrade the longer the router is in operation. I'm not sure how to benchmark network transfer speeds, file searches etc.

Any chance you can get directly connected with the PCs to the router instead of the NG switches? Your network isn't working to best speeds with using 100mb switches since the router supports 1000Mb speeds. Your limiting your network performance.
A recommendation would be to get into some Gb supporting switches instead of using 100Mb switches.
If your using default DHCP IP address pool on the router 192.168.0.100 thru .199, set your PCs up outside of the pool like this:
192.168.0.2 thru .99. Set these IP addresses on each PC. Subnet mask will be 255.255.255.0 and gateway will be 192.168.0.1 and DNS can be 192.168.0.1 or actual ISP DNS addresses seen under Status/Wan section. Disable DNS Relay.

Just wanted touch up on this.
Our network is still deteriorating in performance. Now we're down to only seeing two computers over the entire network (the 2 windows 10 computers).
Windows 7 computers Crystal-pc, Curtis-pc, Central-pc have always been directly hooked to the router NOT through a switch and still drop out of network view randomly with the other machines.
One workaround that I have been doing for the past month was to restart the central-pc computer on a daily basis. This resulted in EVERY computer on the network showing up perfectly under network view for the duration of the day. The next day I would reboot central-pc again and same result. I do not know why this is like this but it was working for a month consistently. towards the end of the May though, the network would loose views of the other computers and ultimately rebooting did not do anything.
We recently acquired some wireless printers which I added to the network wirelessly but they too also disappear from network view unless there is a power failure and the router is rebooted.
I think this router is bad. Just wondering if you've ever had similar experience?

Only thing I'm thinking is that this one Windows 10 PC seems to be possibly causing issues on the network and something with this PC and the router is not working well together.
Just trying to remember here if we had you factory reset the router, re-load FW, then reset once more then set up from scratch?
Might try going back to v1.04 and test. Someone said v1.04 has fixed something for them recently that the most current FW broke.
I think the next step maybe would be to see if you can get into a different D-Link router if you can and test something different out. While this is happening, you could take the 826L home put it in a different location to see if the problem follows. Then you'll know for sure. Check out either a local shop or an online e-tailor that has a refund policy. OfficeDepot/Max carries a 15 day policy. I just demo'd the DIR-885L from there then took it back as I didn't need to keep it. LOL
If there is a price point or budget you have, I can recommend something.
I've never experienced this issue on my network with any of my routers including the 826L and have numerous devices connected.

wow forgot about this thread.
just wanted to update, over the summer I took the router in to the place we bought it since I had purchased extended warranty with it and they kept the router for a week trying to replicate other computer disappearing under their network views in windows and they could not find anything wrong with the router.
I've since shifted to looking at the network here and am trying to learn about master browser polling and election. Seems like if a computer that is always on maintains its master browser status longer than 4 hours, the other pcs will lose the other computers under network views. If i reboot the pc that currently has master browser status, it will then go to another computer and the network will show ALL computers fine.
Can anyone offer suggestions as to how to go about fixing this? I don't know why my network is disappearing when one computer holds the master browser status "too long." If I reboot that machine, master browser goes to another computer and everything works fine... until after a certain amount of time.
Very frustrating.

This computer that keeps the master browser too long Windows 10?
I wast thinking that the last posts you mentioned that one PC if it was rebooted the network PCs were displayed. I'm thinking this one PC maybe the root cause.
Might want to start looking into this:
