Cannot secure wireless network
Hi, everyone. I'm in a sorry situation here, and really need your help.
I switched my ISP to Comcast yesterday, despite all the complaints I'd heard about their support, because I felt it was my only option for getting enough bandwidth for HD streaming.
Unfortunately, no one asked me if I was going to need wireless access to my network, and I didn't think to mention it. It was only after the installer left that I realized it wouldn't work. The cable modem does support Wi-Fi, so I called Comcast support, and reached a very nice lady who wasn't able to give me much help.
What I've found is that I can not access my network with a password. I've tried over and over, both on a Windows 7 system and a Mac. I set it up on the modem with a WPA2-PSK (AES) password and match that on my other computers, but it continues to tell me that the password is invalid. I do have wireless access if I leave the network completely open, which I had to do to get online to post this.
What can I check? What could be causing this problem?
