It's a Belkin (never again, but I have belkin gear now so I'm stuck with it)
Got the router to check for firmware updates but it says there's nothing available.
There's one or two more channels to try but most of them give me no real improvement. It's a fairly big house, with mostly brick walls, and as I say, a lot of water pipes between the router and the console. The distance isn't actually all that big, there's just a lot of stuff to go through, I'm on a different level to the router too.
edit: channel 7 seems to vary from 35%-45%, it can sign in in under a minute but often drops out after a few more minutes. Oddly enough, I've actually been able to download a demo whilst trying all this. Sometimes the download seems to slow right down, other times it appears to have gone pretty fast.
