I have a lenovo laptop that I am using and am trying to connect to my roommate's wireless internet. I cannot connect to the wireless network-I can see my roommate's network and I enter in the password but for some reason it does not connect. I can connect to other wireless networks at work so the card is not the issue. When I take the ethernet cable from the wireless dsl modem/router and plug it into my ethernet jack I connect to the internet just fine. I have unplugged the modem but this has not worked at all. I am pretty sure that I am typing in the correct password. My roommate is a mac user and he has an airport extreme wireless router connected to the actiontec gt704WG modem via usb and ethernet cable. Would that make a difference? I downloaded airport for PCs and it says it cannot detect any wireless devices. Any suggestions would be appreciated.
