I am attempting to use an old mac book G4 (version 10.4.11) to receive wireless in my house and repeat it through an ethernet cable to my xbox. In an attempt to create a cheap wireless receiver instead of the 60 to 100 dollar model microsoft sells and also to avoid buy 300 ft of ethernet cable. If anyone would like to provide insight on why it isn't working for me that would be great. So far I have allowed personal web sharing in the network sharing and also turned on internet sharing from air port to built in ethernet. If anyone can tell me why this isn't working I would be very appreciative. Just trying to do some online game as cost effectively as possible.
