Router kicks random devices off the network multiple times per day

First Timer
Message 7 of 7

My router is kicking random wireless devices (sometimes all of them) off the network multiple times per day. When I try to reconnect my phone for example, I get the error message "IP configuration failure". 

Sometimes the issue resolves itself after half an hour or so, and sometimes it needs a reset.

It's not an issue with wired devices - I can still connect to those remotely via 4G when the WiFi goes down.


This needs to be sorted ASAP - I'm regularly away from home and I need to be able to connect to my devices at home via the cloud - I wouldn't be able to reset the router remotely and would be stuffed (thankfully hasn't happened yet but this issue seems to be getting worse so it's just a matter of time).


I've had issues with the router since day one - the regular resets due to "kernel panic" were resolved in an update which was pushed to the router, but now this has cropped up.


Honestly I'm fed up of the constant issues - not what I would expect from a long established ISP.

Hi Wook93


That's great, please let us know if you do experience any further issues.

Hi Debbie, 


Yes, it seems that the only way to resolve this problem is by restarting the router (Its happened before just as I went to bed, and when I woke up in the morning it still had the same issue, so I was forced to restart the router).


That being said, I took Keith's suggestion yesterday and enabled band steering, and changed the WiFi channels to some less congested ones, and the issue hasn't reappeared thus far. 

I'll keep an eye on it and if I have the same issue again I'll update this thread.

Hi Wook93


I'm sorry to hear this.


I've completed a line test which hasn't detected any faults but I can see re connections on the line.


When you experience this issue do you reboot the router?

How frequent are these log entries & do they occur at the same time that a device is kicked off? I would think that entry refers to TalkTalk's remote monitoring & would have nothing to do with causing devices to disconnect.

I've just checked the router log and it is full of entries like this:


[Critical][Config-Log] Terminal:ACS(,Result:Fail,Type:Authorization


Checking further up in the log, these entries only started to appear a few days ago. 


It doesn't sound like it's a local wireless issue from the look of these entries?

I doubt very much that it is the router disconnecting devices randomly from your network, but WiFi interference in your area. 


Slow speed, intermittent dropouts, breaks in the signal, or no signal on some or all devices, might be caused by Wi-Fi interference from other local networks, which can also lead to a permanent reduction in speed. No ISP can be responsible for your local environment, this is mainly a by-product of the popularity of Wi-Fi.

The Huawei DG8041W TalkTalk Wi-Fi Hub is a dual-band router & offers both the older 2.4GHz & the newer 5GHz Wi-Fi bands. The problem is these are two different networks (SSIDs), but they share the same name, so you can't tell which one you are connected to. Log into the router ( and enter a username of "admin" and use the unique router password (see the label on the rear of the router at the top).

Go to:-
Dashboard > See Wi-Fi Settings > Manage Advanced Settings > Advanced Configuration > WLAN > 5G Basic Network Settings

Append "5G" to the end of the network name of the "SSID" field. Then click "Apply".

This will not fix your issues, but it will make it much easier to identify the band you are connected to. This way you will know which band is causing your problems.

Having said that, there is another approach which can be better, which is to use Band Steering. This will automatically move any 5G compatible device connected to the 2.4G band to the 5GHz band. To use this facility on the DG8041W Wi-Fi Hub, leave both network names identical and enable the Band Steering option at:-

Dashboard > See Internet Settings > Manage advanced settings > Advanced Configuration > WLAN > 5G Advanced Network Settings

Generally speaking, the 2.4GHz band suffers much more from interference than the 5GHz band, but the 2.4GHz one can sometimes have a better range, but this all depends on your local area.

You may then wonder what was really the point of this if it won't solve the problem? This is because the whole topic is too complex to be dealt with in one post. The next stage involves sending out a guide to you to help you get me some important diagnostic results, so as I can analyse them for you and recommend changes to your router configuration to solve them.

I only send this out to people who request it.
