Hi, first time poster here. I'm having trouble connecting to my home wireless network on my newly bought Mac Mini. The computer recognises the network, but when I enter the 26-character WEP key it tells me the "computer was unable to join the Wi-Fi network" that I selected. On the wireless security drop-down box I selected "WEP 40/128- bit hex" and I've tried entering the key with and without the $ sign in front. Does upper/lower case make any difference? In any event, I've tried all conceivable permutations and none have worked. The router is a LinkSys Wireless-G. I'm not very tech-savvy, so any advice would be greatly appreciated!
