Previously when using Fibre 65 we had no buffering issues at all.
But since upgrading to Fibre 150 2 days ago, BBC iPlayer is now pretty much unwatchable due to buffering every 10 minutes (all other services seem to be absolutely fine).
Speed test confirms our internet speed is now 155 Mbps.
We have a brand new Talktalk TV Box (NGTVNETBOX4KN) and a brand new GFAST Modem (SABBF4370GMODN) as part of the upgrade to Fibre 150.
But the router is still our existing (~6 years old) Sagemcom FAST 5364.
The router is 1m away from the telephone socket.
We have tried switching everything off and switching back on again - this made no difference.
We have a direct ethernet connection from the router to the TV box and have tried switching the connection to Wifi - this makes no difference.

Do we need a replacement Router?
