I have read dozens of threads from this forum and others and have yet to find the answer to my problem. The AirPort on my MacBook Pro (still have Mac OS X 10.4.11) works on college campus, free WiFi at coffee shops and in hotels, but it does not work at my parents house or my brothers house. I put in the password and it searches for the PPPoE for a while and then comes back saying "Could not find PPPoE". I am limited in my computer knowledge so basic language is appreciated. The router at my parents (the one I use most) is a: Wireless - G 2.4 GHz Broadband Router 802.11g with Speed Booster LINKSYS The Mac Address or Base Station ID is correct in AirPort except for the very last letter. AirPort reads a 'D', but the router's sticker has on it that is should be a 'B'. I don't know if that makes a difference or not, but since AirPort does it automatically I don't see how to go in and fix that anyways. Any suggestions or ideas about what is going on?
