Hi, I haven't any experience with this router but have a couple of Edimax PCI and cardbus wireless cards which work well. When you say the 'ready' light blinks, is this the ADSL light? If so, then this won't connect as presumably the light needs to be steady in the same way as the BT modem. If the router can't sync to the ADSL signal but the modem can, this suggests it's faulty (assuming it's connected to the line in the same way). If your friend could swap it for a Netgear router (e.g. DG834G) this might be easier!
