Check the wireless channel in use - it may well have changed, especially if on auto. Others have reported the auto function does not work too well in any version of firmware and have had to do their own local survey of channel use and set the channel manually.

One interesting tale I have to tell related to this is that I was called to a friends house after they had a Superhub installed by a VM engineer. Their Wifi performance was poor. The engineer claimed to have set it up optimally.

What I found is that he had simply moved the ethernet cable from old cable modem to the new and left the original Netgear (VM supplied) Wifi router in circuit and powered on. Both Wifi's were still on and the auto-channel function of the Superhub did not know what to do, especially as they had another business Wifi network in the house too. I pulled the Netgear router out of the network, switched to manual channel selection, after checking which channels were in use locally, and everything worked fine.
