Yea, the computer still can't browse or access the internet in any way. The Mac is still connected. It is able to browse with the changed DNS address. However, I only changed the DNS on the PC. I didn't change any DNS settings in the router. Also, the channel has been set to 9 since I spoke to Linksys on the phone a week ago or so.
What do you mean turn off encryption on the card? I can go into the router settings and turn off the WPA, but is there more to it than that?
As far as other posters helping out, Freaktech had posted in the beginning but hasn't posted in a while. Does anyone else have any ideas?
