I've just taken advantage of the PC World Linksys WAG354G Router / WPC54G laptop card offer in the UK. Having installed the kit, it's very noticeable that the wireless signal varies in strength the whole time, even when the laptop is next to the router. I've tried changing channels and am currently using 9 to avoid 11, which is in use next door. 1 and 6 give a much reduced signal strength, so are no go. Am I correct in assuming that this is one of the 'features' of wireless networking? Or is there anything I can do about it?
