Mac notebooks cannot seem to maintain a wifi connection after being installed the Mac OS X 10.5.2 Update. The problem was mentioned to persist by some users even though the wireless signal icon remains full. Users of both Tiger & Leopard Mac operating systems seem to be experiencing the same problem. One could sit only 5 feet away from the wireless router & still there would be a problem. It’s a major issue to be solved by Apple because wifi is a very important function especially for the notebook users.
