Why does'nt my new wireless password work?

[Maggs]

I have at&t and a Macbookpro laptop. I always use wireless internet with a 10 digit password. I noticed i suddenly didn't have internet so i used the house computer and went on the website that at&t provides to change the password so I changed it and saved it. I noticed my brother changed it because it had a new hint. So the problem is that the new password isn't working and my non wireless internet also stopped working out of nowhere on my home computer, i am currently using my phone so if anyone can help please and thank you

Looks like there are number are issues going on. Issue one is connection to AT&T. Issue two is wireless connection. Lets handle issue one first. If AT&T password is changed, then your local router (if you have one) which connects to DSL connection need to configure with new password. If your MAC has special connection software to AT&T then make sure it is using new password. Use only wired connection to test that AT&T connection comes up. That way wireless issue is not in the equation. If AT&T new connection does not work even after your router password is correctly configured, reboot your router. Also to be on the safer side, reboot MAC.

Once the connection to AT&T works, look at the wireless connection. It should come up with your 10 digit encryption key. If it doesn't check with netstat command in the terminal window, your network connections are configured and working on MAC.
