Anyone know anything about how broadband actually works?

O2 broadband seems pretty good- I've got it.

The router, however, is not so good- keeps losing the wireless, then finding it, then losing it, then finding it- cycles every 30 seconds.

Pretty annoying.

that's a fucker.
it happens a bit with my wireless now, and as my music is on the network, it means that itunes resets the location of my library back to the c drive, and i have to reload it. PITA.
