I've been getting the same issue in the last week on Talk Talk Fibre Large connection.

I resolved it by turning off the router for 30 mins to reset the connection, which actually gave me faster speeds than ever before.



It then ran fine for 3 days and the same problem occurred this morning and I also resolved it by turning off the router for 30 mins.

Talktalk have been no help in diagnosing the issue - I'm not sure if there is some connection to upgrade of the HG633 router firmware to v1.21t which took place a couple of days before the issue started.

Are you testing over wireless?

It depends on what browser i use.

EDIT:

My results are via WiFi
