I've had this router for about a year but have only used it wired. It's only recently that I had a friend stay with me for a few days and he was getting poor signal in the next room. So I tried connecting my laptop (Intel 3945 a/b/g) from about 10-12 feet away (direct line of site) and I only get 2-3 signal bars. Same with my PDA. The router is on top of a shelf and I don't have a cordless phone in my apartment. However, there are several other wireless signals floating around; but none are on the same channel. I had it on channel 11 but I have tried others without any change. Was previously running Tomato 1.21.8005 with Victec's mods but have flashed to the latest stock Linksys firmware because I will try contacting CS soon to see if I can get a RMA because, while I can live with it now, I would like a properly functioning device for such a time when my needs may change. I guess my question is if this is a valid reason to get an exchange under warranty from Linksys. Everything else has been perfect with the router and I have no complaints. Thanks.
