My mac mini has been giving me fits about airport... Im connected to a Linksys WRT54G Router, and about every hour or so I have to turn airport off and reconnect to the router.. this is not the case on any of the other wireless computers in the home.. all my peecees remain connected and dont lag out or anything... Its only the mini.. Ive replaced the router twice now and still no fix.. and the mini is in a place i cant run ethernet cable... it shows connected all the time but ill lose connection... i get full wireless strength too
