Have had infinity now for 8 months or so and ever since upgrading I have trouble connecting to websites with either 'resolving host' or 'waiting for web site' listed in bottom left corner. One of the worst sites this happens on is in fact BT.com! At times sites don't even load at all or correctly.
I have checked down/upload speeds and they seem to be fine most of the time at around 75/17MB per second. Today however this has dropped to 41/17MB.
