I need to re-locate the PC to next room, but leave the router where it is, as no 'phone socket in next room. The PC has cable to the router, our laptops are wireless. I shall need a USB wireless adapter for the PC, and am seeking advice on what to buy. I am on TalkTalk 'phone and broadband, if that is relevant. Are there any points to look out for when setting-up these adapters? Any advice much appreciated.
