Try a shorter password?
We have Comcast cable internet that is being run through a modem to a linksys wireless router and then through to an airport extreme base. There are 2 mac users in the house who can connect wirelessly with no problem, but the 2 PC users cannot. The problem is that the password is 20 characters long and XP will not accept this as a valid key length. I know this is the correct key because the 2 Mac users used it to connect their own computers.
At this point, I've tried everything I can think of and nothing is working. The person who set up the connection no longer lives here, so I don't think we can just reset the password and I'm not sure how to override the error message.
When I view available wireless network connections, I can see it with full strength, but when I click to join, it just attempts to connect for 60 seconds before timing-out.
I have an HP running XP SP2.
Any help? Please!!
