I have a mac computer , configured for dhcp to connect to various wireless networks via an airport card... I also have a wireless network at my house (linksys router) to connect to a dsl line, and have had some problems with the modem. the mac refuses to connect. it 'says' its connected, somtimes even shows a signal strength, but it doesn't. There is no encryption (because of this little pest). The mac computer (supposedly) connects fine to other networks, but the time it is connected is a lot shorter. I wish i had more info about the mac's configuration, but i'm not a mac guru, so i don't know how to test much..

any help is greatly appreciated
