Title: Losing dhcp clients and reboots- lose smb
Post by: mikey4u on August 22, 2018, 09:06:42 AM
Have a problem for a couple of months now. I seem to lose DHCP clients on the connected list (Front page of router log in). Happens mostly at night or evening. Also the router often reboots. Is this a security problem. Should I install the last beta firmware patch.  Could something else cause this. Also I seem to get my smb shares randonly. Sometimes it is visable on my computer sometimes no. Starting to lose my mind.
ps last months added wifi light swiches. total connections average 25-30 DCHP client connections

You can update. If it doesn't work for you you can revert back to v1.20.

Yes I will try the update as a last resort. Is there anything else I can do to resolve this.

Possible that one of your devices could be causing this. You would have to disconnect them save maybe a few and leave connected and see.
Also what browser are you using? Seeing same UI behavior in IE11, FF or Opera?

Yes tried disconnecting them one by one. May slow down the process but it eventually come back. I usually use firefox but tried chrome with similar results.

Are all the devices connected to the router or do you have range extenders?

Does it tend to lose connectivity during streaming or heavy network load or completely random times?

Are there specific devices that are disconnecting?

If you disconnect the drive from the router does everything else run normal?

What is the Mfr and model of this USB drive?
Size of the drive?
Does it have it's own power supply adapter?

The drive is
Seagate Backup Plus 4TB 2.5" 5400RPM USB 3.0 Portable External Hard Drive (STDR4000100)
It does not have an external power supply

Larger sized drives sometimes need additional power.  :-\

I would temporarily disconnect the USB drive and just run the router and your other devices and see if the problem still appears...

Yes I tried that with no drive but still lose dchp client lists over time, sometimes I can still reach device with a direct ip address but fall off list. eventually all drops from the list and router reboots. Actually seems to happen when i go check settings home page with firefox, chrome or app. if I don't check it or log in it seems more stable. As far as smb shares tried a 500gb drive with same results. If I take the drive out then I obviously cant see the smb. The more I think about it, it seems the dchp list drop to be related to logging in to router though web sever or the mydlink app. CONFUSED...

I would go ahead and install the FW beta update. Factory reset, install, factory reset once more then setup from scratch.

Are the devices actually losing connectivity or is it ONLY in the Connected Client list in the UI? Need to know if this is cosmetic or the router is actually dropping your devices.

Ok yes first starts dropping dchp clients from list only cosmetic. as I lose more "cosmetic"clients off the list ( can still access them) over time. When the list is down to only a few then the router starts to actually drop them and eventually restarts or reboots. but it seems provoked by logging in to router UI
Almost feels like i am being hacked but that is probably ulikely.

Ok had to turn on upnp even if i didn't want to for security reasons, but that seems to make my dchp list more stable. As for smb had to turn on and off samba shares repeatedly until it took switch-check-switch-check. Now my dchp list seems stable,no disconnects for the moment, and smb shows up on my computer. pretty buggy software. I believe that did the trick. let you know if it holds long term. good for now.

Thank you.

UPnP can be left enabled. Its not a security concern anymore. Though disabling it probably shouldn’t cause the problems you were seeing. Something D-Link should look at.

Ok solved my problem. it is obviously interference on 2.4 ghz. I actually own two DIR-890L. i disabled the 2.4 ghz on my main router, the other two 5ghz left on. Added my second as an AP and linked them lan to lan and moved the second router about 6 feet away. the second has all three radios turned on. Now no more drop outs. no more reboots and dhcp client list is good. Tried changing router location router order. In my case its the only thing that worked for me. I know its strange. Not tech enough to tell you if it is the routers or my environment. I believe it to be my environment. Anyway it works now and my obsession is over. time to move on lol.

What channels are you using on both 890Ls?
Title: Re: Losing dhcp clients and reboots- lose smb
Post by: mikey4u on December 11, 2018, 01:26:55 PM
Use channel one on second router for 2.4ghz and auto for two other 5ghz. The first router has only two 5ghz on auto. works like that for a little while. I am leaving it like that because it works for me now.

The 1st router should be on channel 11 on 2.4Ghz if the 2nd is using channel 1. This should not cause problems with this configuration. I would also set manual channels on 5Ghz as well between the two. Auto maybe causing problems when in close proximity to other wifi signals. Use same far channels from each other. I do this with my stuff. No problems.

What is the distance between the 890Ls in there final places? Should be around 30 feet in between to start.

Ok leaving 2.4ghz on main router just causes me problems even if they are on different channels. The 5ghz seems to work fine on auto, streams hd with no intreruption. the routers are only 6 to 8 feet apart. There may be better configurations but works like this after months of frustration. So I am going to leave it like this. This happened because I moved to a new house. I will play with this again when I purchase a new ax router.
Thanks for the feed back.

6 to 8 feet is TOO close.  :o The WiFI range on these routers can cover well up to 30 feet. I bet you wont have any problems with 2.4Ghz if you give more distance between the 890Ls. If your going to have them this close, it would be best to turn OFF ALL radios on the main host router.
