Wifi Hub Regularly Restarts - Line tests are fine

First Timer

I have the new WiFi hub and around 78mb speed, and when the internet/router is working the I am happy with the service.


Unfortunately I am suffering from intermittent reboots. When it starts rebooting in can happen between 3-10 times before it eventually settles back down but then then happen again at any time although it can also go days without restarting.


I have contacted Talk Talk via the chat several times and gone through the usual script of testing and changing my Wifi channel and sometimes this works for a few days, but the problem always comes back.


When I check the logs there are some very change things happening. Firstly the logs go back to 2012, but I only got the router this year! There are also logs from 2017 but they appear at the top of the list as though they are the newest.


When checking the logs there are a lot of failed DNS lookups, I have tried changing the DNS settings to use Google's public ones ( & but the logs are still happening and the restarts still occur. 


Last night after the 3rd restart I checked the logs again and it showed random devices connecting and disconnecting every 3 seconds, after identifying one of the devices, a new Xbox One X, the restarts did stop for a while.


I am certain that there is a technical fault with the router, the logs showing from 2012 and 2017 are clearly a mistake and the constant restarts are becoming extremely frustrating as we watch a lot of Netflix and On demand TV and play online games frequently.


How would I go about getting a new router?


Thanks in advance

Hi @Wayno1979 


I have asked one of TalkTalk's OCEs to pick your thread up and investigate it for you.

The forum is not real-time 24/7 support, so depending on how busy they are & how many are working at any one time, this can take 24 - 48 hrs (excluding weekends & limited cover on Bank Holidays). Alternatively, you can call the call centre or use online chat. The posts are responded to in time/date order, oldest first. So the fewer entries you make on your thread now, the sooner they will pick it up.

To save yourself time, please make sure that your community profile includes your first & last names, broadband phone number & if possible an alternative contact number. This can be done by clicking on your Avatar picture then click on "My Settings" followed by:-

Otherwise, TalkTalk will not be able to tie up your forum username to your broadband account. Only you & TalkTalk have visibility of your details.

I am not employed by TalkTalk, I'm just a customer. If my post has fixed the issue, please mark it as the Best Answer.

Thanks  @OCE_Arne


Fingers crossed it resolves the issue, my router restarted around 10 times yesterday evening between 5:30pm and 11:30pm!


DHL are delivering the new one today.

Hi @OCE_Michelle 


New router seems stable so far, speeds are still a little lower than before and the firmware is not up to date, but from memory the previous router was fine until it got the latest firmware update so this isnt necessarily a bad thing.


Will monitor over the next few weeks and see how it goes, especially if it does get the firmware update.

Glad to hear things are more stable.  Do let us know if anything changes.

Evening @OCE_Karl @OCE_Michelle @OCE_Arne 


Unfortunately after 2 months of very stable internet my router has updated it's firmware and the issues have returned, 1 restart this morning and 4 back to back this evening.


The firmware version is now showing SG4K10002600t, it's was previously SG4K10001400t and was working nearly flawless with maybe 1 or 2 restarts in 2 months.


It's clearly a firmware issue and not hardware, please can you resolve this asap so I don't end up with constant disconnects like before.


Is there any way to roll back the firmware?


Thanks in advance
