My parents have a WAP54G (not sure of firmware version) connected to a Surfboard Modem. They have a wireless laptop that works fine. I used to be able to connect just fine with my wireless laptop, but now I get "limited or no connectivity". I tried another laptop this weekend, still got "limited or no connectivity". So i decided to check the AP settings. I cannot log into the AP, I have tried "http://192.168.1.245", and also tried the setup program downloaded off of the linksys website, which says "there are no linksys AP's connected. I have seen similar problems on this board but no real solutions.
