I am new to networking, router is Linksys WRT 45G, updated firmware when I purchased. I am also new to the Apple world with an iBook G4. I have been without success trying to access the internet securely and have been running into a brick wall. As long as the security settings are disabled, I can see my router's SSID (broadcasting-enabled) fine. The trouble starts when I attempt to configure the wireless security settings. I can choose WEP, 128 hex...26 characters for the key, chose a passphrase (letters & numbers) when I go to the iBook to connect to the internet and it asks for my password I noticed the wireless icon shows nothing and nothing I do with inserting the key 1 for the password works. I've been sitting in the same room as the router and nada. I've tried WPA Personal, back to WEP--3 hours this afternoon and I've about no hair left to pull. Maybe it's the settings on the iBook, maybe it's the desktop...???? I have no clue at this point. I thought I was following as much information as I have read to the letter but obviously since nothing is working I know I'm doing something wrong. I'm not getting any pleasure out of this iBook and am about ready to throw the router into the ocean. Is there anyone who can help me? I had chosen to go with Apple because of the headaches and all I've had with a Windows system...so I would sure appreciate any advice
