WiFi keeps dropping off and 2.4 GHz signal not working

First Timer
Message 8 of 8

I have a TalkTalk super router HG635 and over the last 3 weeks the 2.4GHZ wifi keeps dropping so it makes it impossible to stream or use the internet. I have done a factory reset of the router and set it up again but the problem still occurs. The 5 Ghz wifi seems stable but not so many devices use this.


Any help would be appreciated as it's very annoying.

Hi.  First thing. Please update your profile s it contains your full name and telephone number to allow an OCE to locate your account.

Do not post that info on this thread for security reasons. Just say completed when you have done this.

The HG635's although a great little router are becoming end of life. Sounds like your hardware is failing.

An OCE will pickup this ticket during Monday to Friday.  They may well / Should offer to send a new router to you.

Hi @AndyHunter,


You could try changing the channel that your router broadcasts the 2.4GHz Wi-Fi signal on, you can use free smartphone Apps like this to see what channels are being used within range of your smartphone, you can then change your router to use channels that are less congested.


If trying this makes no difference then it may indicate an issue with the router, the staff here would be able to help with that.


For one of the TalkTalk staff on this community to be able to look into this you will need to update your community profile to include your name, landline telephone number that your TalkTalk service is provided on & an alternative contact number. This will allow them to identify you, and they will then be able to help.


Don't post any personal details in this thread, just add them to your community profile.


Then they will hopefully be able to respond to this post tomorrow.
