Mac air won't connect to wifi

I cannot connect my Mac Air to my ATT wifi. My laptop connects to other wifi networks, including my phone's hotspot. I have other devices currently connected to the wifi network. I see the network when I click on the wifi icon, but when I try to connect I receive an error that says, "The wifi *** cannot be joined."

Below are some things you could try (no guarantee of success):

In the Network preferences for your wifi/airport, click Advanced, TCP/IP, make sure the IPv4 setting is "Using DHCP" and click the renew the lease button.
In the network wif/airport advanced settings, preferred networks, delete the gateway's wivi ssid if it's there (highlight and click the minus at the bottom of the table to delete).
In the gateway, try changing the wifi's channel.
Ask for ideas in the Apple Support Communities (Macbook Air) forums.
Google search for possible solutions.

Yay!!! This worked! I had to call AT&T and they sucked, then I called Apple and they are about to make me return my computer for a new one. After 2 1/2 hours I am so thankful for this, and if anyone has AT&T U-verse you need to go on here
