We recently switched to TalkTalk fibre and get good speeds of around 20Mbps down and 2Mbps up. However, after a few days or sometimes less this degrades to around 3-4Mbps down and 3-400Kbps up.
Restarting the router or resetting the VDSL connection brings the speed back to 20/2Mbps every time and this is on a wired connection. At all times the router displays a 30000bps downstream and 2000bps downstream connection.
I have read many similar reports on this forum for the HG633 router and before I invest in an alternative (or put the HG633 on a timer socket) I'd like to get my line checked and I have updated my profile with my phone number. I don't think another HG633 is going to make a difference.
Thanks.
