I have 2 macs: an iBook 1.33Ghz and a mini G4 1.5Ghz, both running Tiger 10.4.11. I have a Linksys WRT54G v4 router. The issue started today. I left the mini and the iBook running overnight, like I usually do, and this morning I couldn't get online. Here's how it looks: The airport signal strength is slightly lower on my network on the mini - I can switch to a different network which is simply free Wi-Fi from my neighbor (who has not secure his network with a password), AND IT WORKS FINE, yet when I switch to my network, I can't connect. Same with the iBook. I opened network connection, switch to the working (free) WiFi, then back to my network (which is WEP protected), at which point a dialogue appears asking me for a password. I provide the password, it accepts it, then I STILL cannot get on the net. I reboot, clear caches etc. Same story. I try different options "WEP Password" or "WEP 40-128 bit Hex" etc. No dice. Turning the airport on and off has no effect. Rebooting or shutting down completely has no effect. Basically, I can't get on the net through MY network from my mini or iBook (but can on the free unprotected WiFi network). Incidentally, I also have an XP laptop that gets on the same WiFi network whenever I fire it up, and it too cannot get on... Any ideas? TIA!
