Unfortunately, you've given us little information to shoot at.. Operating system? Updated the wireless drivers lately? Make and model of the computer? Does McDonald's require a password and Starbucks doesn't? The more information you give us, the better informed our answer will be.
Please note that older computer didn't support the WPA2 password security protocols and it's possible that McDonalds is requiring such where Starbucks doesn't? The older drivers on your computer may support WEP and possibly WPA but if WPA2 password encryption is required, it may not work..
Hope this helps.
