I have two laptops that I use in two different locations. One location has a Linksys router the other a Netgear router. Both computers will connect to both routers. Their MAC addresses show up on both routers. One laptop (XP) accesses the internet at both locations, no problem. The other laptop (Vista) will only access the internet on the Linksys router. I have checked the MAC filter setting (Linksys) and the PC Access settings (Netgear) and disabled them but still have the same problem. Any suggestions where to look would be helpful.
