loss of wifi when 2 or more devices connected


hi have upgraded to fibre broadband a few months ago and if i have 2 or more devices in use at the same time the wifi seems to freeze.

Have run a speed test and am getting 39mbs.

Also noticed that if i am watching netflix/amazone/youtube etc which is connected via lan cable it buffers alot when the wifi drops out.

Have factory reset router(hg633) and changed the wifi channel but still the same.

Borrowed a hg633 router offf a friend andt hat was the same.

This is the reason i changed from normal broadband to fibre as ive been having this issue for months.

All my devices are up to date. windows 10 pc,iphone xr,samsung s9 and samsung a70.

At times its so bad with the wifi i switch to mobile data just to finish off what im doing online.


hi this is my second post about this as the first one seems to have disapeared.

I have a hg633 router and am on fibre broadband.

Speed on test page is spot on for what im supposed to get , 39mbs.

If i have more than 2 devices conected to the router it seems to freeze the wifi so it is unusable

Do only wifi devices freeze, do you have ant devices 'wired' and do these work ok?

That is not an issue with your WiFi as your Ethernet connections suffer & obviously you have proved the router OK as it is the same with the spare HG633. 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:-

Personal Profile > Personal Information

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.

Hi gemzie


I'm really sorry to hear this.


I've completed a line test which hasn't detected any faults and the connection appears to be stable.


If you only have one device connected wired does this issue still occur?
