What is your DSL uptime?
Is the line disconnecting its sync and having to re-sync?, another common problem with talktalk is that they (when I was with them) had the connection disconnect when idle, its in the internet connection settings, you want it to never disconnect/always on.

Try changing this and see what happens.
TT Forum Same Fault.
General Help Guide, it does affect fibre, its talking rubbish, its a generic router setting with TT, and needs to be changed.

I believe fibre talktalk routers default to use VDSL IP routing (IP) mode. It is hidden until you connect a FTTC connection, it then kicks in, this mode does not have the 30 minute time out setting as ADSL2+ does.

This mode only exists on HG633 and 635 models, the older routers did time out.

worth a try, all friends that have been on talktalk, fibre or not, have said their router had the red wan light at times, and I logged onto their router and it did this.
so only going on past experience.

I'll have to check about sync however the idle option , not the issue because it happens while using it and also I don't think the idle option is in hg633 but previous router I think ?

See on the new VDSL mode there is no such option.

Do you have 5ghz and 2.4ghz SSID seperated?

I don't but I tested that option ,5hgz only still same speed 33 mb max ,

You will not get full speeds over wireless without split SSIDs, simple as.

You must connect to 5Ghz.

I actually tried this and also only enable 5ghz , speed is the same
Thanks for reading

Tried wireless channel 100?

What device are you testing with?

HG633 can pull faster speeds over wireless, I know, I have tried.
