My gateway is a 2wire dsl modem with a wireless router built in. From the router I ran a cat5e cable for about 150 feet to a linksys wireless access point. With my Axim x51v I can connect to the 2wire just fine and surf the net. My problem is when I disable the 2wire connection and choose linksys I hook up and get a very good signal, but I cannot get on the internet. I might add that my access point is set up in repeater mode. My system works ok with wireless laptops and desktops ok but I just can't hook up with my pda. Thanks, your help will be appreciated.
