I just installed a Dual G4 450mhz chip in my Sawtooth 450mhz. Installed very easily and osX recognizes it great. The problem comes with my wireless network. Worked like a charm before I installed it, and now it asks if I want to join the trusted network "blahblahblah." (which happens to by my network). I don't have WEP encryption enabled, but use MAC address filtering instead. I've reset the modem, router, pulled the wireless card and put it back in. I have no problem connnecting my 2 powerbooks and everything else I have to my network. Any ideas? I thought there might be a firmware issue or something but couldn't find anything.
