So I come home to find the airport signal on my laptop is zero and everytime I click on the icon in the top menu bar to join my network "linksys", I get "Unable to connect to network linksys". I have a linksys router for internet sharing only that is connected to a PC. There's no password on it though I would like to WEP protect it(but I lost the manual that came with the router )..maybe someone here can shed light on how I do this. Anyway, after much corssing of the fingers and one reboot of the iBook, it has now connected to the network and I have wireless internet again. I left it for 10 minutes and the screensaver kicked in and when icame back, it had gone down to zero bars again.. no internet I have no clue what's going on.... Is it some werid Airport behaviour? How do I trouble shoot this? Please help!!
