add me to the list of people with wireless probs

h:
i moved to a new place, and my only option is wireless. i havent had trouble connecting before, but today it just won't work. fyi, it's an unsecured network. in the past, i have also connected to my neighbor's unsecured network :rick:
what i'm using:
desktop with a USB wireless adapter
laptop with a cardbus adapter
basically, my wireless adapters can "see" the router, but can't connect to it. the networks are available, but i cant access them
any ideas?
thanks
