Hello everyone, I have been a mac user since 2006. Yesterday, I purchased an iBook G4 for my father, who I have converted from Windows to Macintosh. We are 99% satisfied. Everything works great except the wireless internet. Whenever the computer shuts off or goes to sleep, we have a difficult time re-connecting to the wireless internet. After five minutes of clicking on the wireless signal (at the top of the screen) and turning it on and off, we are able to get on. Once we connect, it does not seem to disconnect. Weird issue huh? I would appreciate any advice you can give me. If this was already mentioned in a previous threat, I apologize...I am quite new to the site. Please help!
