Hi all, Brand new Mac user here. I already spent a few hours checking old threads and other websites for suggestions, but they didn't help. So, this afternoon everything was fine until a few hours ago when the internet connection inexplicably started giving problems. Before that, I was just browsing on the web. I never messed with any network configurations. I own an iMac 27" (Mac OS X version: 10.6.3) that keeps asking for a WEP password. I write it down but the only thing I get is a "Connection timeout" message. I'm using a SMC router (ADSL 2 Barricade G) by the way. I understand WEP isn't the best choice, but the tecnhician said it was the only way to make all three computers have internet access. With WPA, the two Windows laptops had problems conecting. I changed the client to "No WEP/ No WAP" and every computer can connect to the internet. However, this isn't the desired solution for obvious reasons. On the Mac, I removed the old network settings. I tried the $ (and 0x) trick but it didn't work. I also removed the old network passewords from the Keychain. I know the WEP password is right, because I used it on both Windows machines when I changed the client type back to WEP Only. Since the SMC router doesn't display the WEP password, I'll download some password recovery software to find it out. I doubt this will work, but I'm running out of options. I'm not a tech guy. Hope you can help me out. Thanks.
