Don't buy if you use ATT Worldnet
I bought this unit for a friend who wanted to have wireless for a dialup (don't ask). The Amazon webpage indicated that this unit supported ATT Worldnet, but when I got the unit, the pull down software didn't have ATT as an option. I tried a number of ways to get this unit up and running, but was unsuccessful. I then looked through the manual to determine what was going wrong and discovered that it didn't support ATT. Arrgh.
