Hi,
Just got my DIR-868L and tried to set it up.
I absolutely need DHCP reservation for about 20 devices, computers in the house and set them all up, they're all enabled and all have the right Mac addresses.

Problem is that each time any device, computer, laptop connects, it gets the right IP address for about 3 seconds and then switches to non-sense IPs

All of them are in the 192.168.0.50-100 range.
The router DHCP reservation range is set to serve the 50-199.
They broadcast them always or not
The DNS Relay option is on or off, no difference.

I tried with iPhones, iPads, AppleTV, Macbook Pro, Macbook Air, Samsung Galaxy, HP Laptop under Windows 7 and Windows 8.
All show the same behavior: 192.168.0.nnn for a few seconds, and then all switch to something like 192.168.192.nnn and all lose any kind of communication.
The router itself uses its default 192.168.0.1 address.

I'm a system engineer and know computing and server setup, IP configuration, etc... so the problem is not on my side. The former LinkSys router had the same IP reservations without problems.

When I renew the lease on each of those devices, they all correctly receive the IP addresses they're supposed to get but 1-2 seconds later, gone.

Sometimes, I'm lucky, I get those for an hour.


Now, when I force an IP on a machine, the one it's supposed to get, I can barely connect to the Internet, but then performances are awful. I mean opening a page takes about 3-4 minutes! Either by Wifi or Ethernet.
And I do have a 250Mbit/s cable internet connection at home that is not at fault.
I reverted back to my LinkSys router and everything is fine and amazingly fast. The problem is the DIR-868L

How can one have the DHCP Reservation work on that router?
Is it worth any effort?
It cur rely stay in my trash bin under my desk, and I'm going to throw it away in a couple of days. But I want to make sure it's worth trashing it.
Thanks for any clarification on someone who succeeded in DHCP Reservation

Link>Welcome!

• What Hardware version is your router? Look at sticker under router.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• What region are you located?

PC Web Browser Configurations
What browser are you using?
Try Opera or FF? If IE 8, 9, 10 or 11, set compatibility mode and test again.
Disable any security browser Add-ons like No Script and Ad-Block or configure them to allow All Pages when connected to the router.
Clear all browser caches.
Be sure to log into the Admin account on the router.
Try turning off these features in Chrome:
Top right corner, little bars for options > Settings > Settings (on left) > Show advanced settings.
Uncheck these:
Use a web service to help resolve navigation errors
Use a prediction service to help complete searches and URLs typed in the address bar
Predict network actions to improve page load performance
Enable phishing and malware protection

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. Besure to log into the Admin account on the router.

• Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS or Gamefuel.
• Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
• Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
• Turn on DNS Relay  under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench and input new DNS addresses under Setup/Internet/Manual.
• Setup DHCP 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 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 to test.
• Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding 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, and WPS under Advanced.
• WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
• Set current Time Zone, Date and Time. Use an NTP Server feature. The DST setting is only needed in the NA region. Tools/Time.

Does using the default DHCP pool range of .100 thru .199 exhibit the same thing?

[sjordi]

Hi,
I have firmware version 1.07
In Switzerland.
I'm using FireFox or Safari on my Mac, but the configuration has nothing to do with the browser itself. How would that be?
And yes, I did refresh everything. I automatically erase the cache each time I quit my browsers.

All the options you mention are as you say:
- No QOS (actually out of the box)
- I don't have advanced DHCP or Parental controls
- Unicasting was OFF; I turned it ON
- All Mac addresses have a unique TCP/IP address
- Each device has DHCP on, not static IP
...


Nothing different. I get absurd IP addresses I never mentioned anywhere and which are not in any kind of defined ranges.
192.168."192".nnn doesn't make any sense.

I don't know whether setting the range from 100 to 199 would ale any differences. I need them to be between 50 and 89...

• Was a Factory Reset performed before and after any firmware updates then set up from scratch?

FW Update Process

Did you load v1.07 from this site? http://www.dlink.com/de/de/support/product/dir-868l-wireless-ac1750-dual-band-gigabit-router

What OSX version is on the Mac? Im currently using 10.9.2 and 10.7.5 and haven't seen this issue yet, however I mainly use .100-.199 default DHCP pool.

I'd test the default DHCP pool and see if the problem still persists...

I'd turn OFF ALL devices accept for one, then begin to reserve the IP address, let the router reboot and turn on the next...keep doing this to graduate...might find where the issue comes in.

[sjordi]

Hi,

It is just out of the box, brand new. Received on thursday... So no firmware upgrade.
You can see a 2.2Mb screencast I just shot from my Mac at https://dl.dropboxusercontent.com/u/11649154/dhcp.mp4
It's in real time.
And it even was worse: sometimes I got addresses like 132.244.117.9 and no Router address.

I'm using Maverick 10.9.2 just like you.
I can't use any kind of range in the 100-199 since some of my software and devices require fix local IP
But I can try to assign a 110 to my iPhone and see what's going on.

I already did turn everything off. Same behavior when I have only my Mac or only my iPad. Even only the HP laptop, which never gets the right IP.

Really too bad.
And as said, if I force a manual IP address on one of the devices, then it takes forever, if ever, to actually reach the Internet.

[FurryNutz]

I would do a reload of the FW found at the link I provided and follow the FW Update Process linked as well and see if a reload of code will help resolve this...Seems that this maybe a FW or router issue.

If the FW load doesn't resolve this, I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email. You may have a bad unit.

[sjordi]

Ok I will try this tomorrow (already late here in Switzerland).
If it doesn't work, then I'll call.
Thanks

[FurryNutz]

Let us know how it goes. 

[sjordi]

Ok,
I'm back from my trip and tried everything again, lost my entire morning.
- Reset to factory settings
- Reflash of the latest 1.07 firmware just downloaded from D-Link
- Everything is fine as long as I don't reserve DHCP addresses.
- Enable DHCP and leave 100-199 as the default range
- Add 1 fixed IP address for my Mac, 192.168.1.101
- Add 1 fixed IP address for my HP Latop,  192.168.1.102
- Add 1 fixed IP address for my iPad,  192.168.1.103
- Save the settings

Then I renew the lease/reboot all of my items. They all get the right IP addresses for 1-2 seconds then get random address, out of range, and of course are cut from the Internet.

This is crazy.
Steve

[FurryNutz]

Are you adding these "fixed" addresses to the router or on the device?

Care to have someone review your router settings with you sir? 
Maybe someone can review your router settings with you using Link> teamviewer if your interested. Its safe and secure.

[sjordi]

I opened a ticket with D-Link
Problem with TeamViewer, which I have and use, is that I can't connect to the internet while using the DIR-868L...
Unless I connect another way and we access it indirectly but then how can I test the IP attributions?

[FurryNutz]

We could try factory reset on the and TV from there maybe...Does any devices hold an IP address after the factory reset?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modem Mfr. and model # do you have?
• Is ISP Modem/Service using Dynamic or Static WAN IP addressing?

[sjordi]

Hi yeah I thought about that.
TeamView and have only 1 reserved IP for, say, my iPhone. Then I have a utility to mirror it to the Mac screen so it could also be seen from the partner on TV...

- My ISP is Cablecom, in Switzerland.
- The Modem is a "Ubee" (https://support-en.upc-cablecom.ch/app/answers/detail/a_id/66/kw/ubee, at the bottom). I do have a Horizon which is a Samsung SMT-G7400 but I'm not using it as my modem, it's linked in the home movie theater room for that purpose only. I disconnected it to make sure it was not conflicting with the Ubee. The current LinkSys modem works perfectly with DHCP reservation.
- The ISP provides Dynamic IP to the modem itself, if I'm correct it's changing every week.

My wife is currently in the middle of college exams and needs Internet access, and I have a time difference (GMT+1) so TVing would be difficult. I need to do this when she's away 

[FurryNutz]

Understand...
Is there a model # for the Ubee modem?

Is this modem carrying the NAT or have a built in router by chance?

[sjordi]

The Ubee is EVM3206
It's just a modem, with 1 Ethernet port and nothing else. No built-in router.
It's NATed. I need a router to use more than 1 device on it, hence the
LinkSys and/or the DIR-868L... and the fixed IP for some of them.
