Hi, same HG633 router, same problem, during data upload from YouTube or Dropbox nothing else on my home network is able to access web pages.
What is the model of the replacement router please?
The replacement router that eventually cured the problem is a TalkTalk branded D-Link DSL-3782
Hope this helps
