I spend a lot of time on the road and need to connect to the internet from time to time. I normally drop into a Starbucks, Barnes & Noble, etc. Recently I've been unable to connect to ANY of their attwifi networks. I can use wifi at home, other places that do not use attwifi as a network name, hotels, so I know my wifi card is OK on my computer. I can also connect to attwifi on my phone - but not the computer. I did try a google search but did not find any real answers. Any idea what is going on?
