What problems are you having in terms of wifi though?
It's just getting annoying. The hub is in the hall I can see it right now, in yet wifi signal isn't great in the lounge.
You might like to consider purchasing a different VDSL router with two or more external wireless aerials instead. External aerials have a better ERP (Effective Raidiated Power), which makes better use of the small wireless power level which is allowed in the UK.
My advice is to leave well alone. It is total rubbish and consumers are now being used to do painful beta testing on it.
I endured 3 weeks of misery before reverting back to HH5. Just have a look round this forum and just don't do it.
I would expect this issue to be picked up by the mainstream media soon.
