Hi to you all, I couldn't figure out how to create a secure wireless network with WPA or WPA2 between my iMac, two laptops and iPhone... So here is my setup: iMac Intel Core 2 Duo, 2.4GHz, 20" (Mid 2007) with Leopard 10.5.6 (latest update) iPhone 3G HP Compaq 6820s, Intel Core 2 Duo, 1.6GHz, with Vista (I must appologise for this but it's a slimmed down/tweaked vista that works quite ok, I am too lazy to update it) Old Fujitsu Siemens E7110 notebook with Windoze XP with a USRobotics Turbo G WiFi card So, now to my problem: I want to create an Ad-Hoc network on my iMac to link all my devices. But I can create only a WEP encrypted network, and that's not exaclty secure if people can break it in under 2.5 minutes. And, if I create an adhoc network on my Vista machine with WPA2/AES, which oddly enough I can make in Vista, none of my devices can connect to it, they see the network, but they just say "incorect passphrase". And I know I typed the password correclty at both ends... So, I am clueless! I know that if I buy a WiFi AP Router, it will solve my problem, but my room and desk is cluttered as it is now, so If I can make it work with an AdHoc network I will be excellent... Also, since I am a student living on campus, I am quite concearned about security... Thanks for reading, and maybe you can put me out of my misery, cuz this problem is just killing me! Cheers, Plucky!
