Hi London_Exile,
It certainly sounds like a network fault to me, but we'd need the full postcode to be able to investigate further (as you can imagine, there are a lot of sites in SW11).
Since you were able to pick up a weak signal, I would rule out a problem with the modem, the software and the laptop. That only leaves a network outage, which we can check better once we have the full details
