That graph is blank. Has your IP address changed with the router change?
Can you confirm which O2 package it is please? Sorry to query it, but we have had two posters in the last few months both thinking they were on non-LLU when they were LLU, and there is a faint possibility you are the opposite.
I don't remember my O2 LLU graphs being anything like yours, using a Netgear 834PN, but unfortunately cannot access the graphs now.
