I started to chime on yesterday upon seeing your message MacFloridaKeys but decided not to as I couldn't really address your problem given that I do not have the USB Card you are having problems with and I have the Intel MacBook Pro. I also wanted to deflate what I saw as a forum storm brewing between you and 3GMAC but I guess I'm too late in that regard!
I would hope that we can get past hurt feelings, name calling and the like and actually deal with the issues that bring us together on this forum - helping one another out! C'mon, I could see if we were PC users but we're MAC people and have a higher calling!
I actually came upon this forum in response to a post by someone having problems with their aircard. Working in NORAD and USNORTHCOM enables me to work with plenty of IT solutions and I currently have five different aircards - having used them for about six years now. So, with the exception of 3GMAC giving me some pointers about how to get one of my cards to work natively with my MAC (thanks once again), after I upgraded to Leopard, I am pretty experienced with using all three types that he mentioned and have had no problems.
I would take the advice of akita11 and get with AT&T on getting your card setup to use on your MAC and barring there being no problems with the setup and network prefereces configuartion, actually look at the possibility that you may have a faulty card (I did have a bad GT Ultra Express card that I had to swap out with our AT&T rep). In the "duh" category, when I first used the USB Connect 881 card, when I plugged it in I saw lights but I had neglected to put in the battery to the unit, which was small and hiding behind the setup docs. I'm sure if you are persistent with AT&T, you can get the assistance you need.
As for getting emotional - I understand where you're coming from - but also understand 3GMAC's position as he reminds me of a friend of mine, who I met when we were working on our MBAs. He was a BLUF (bottom line up front) no-nonsense "just give me the facts Ma'am" kind of guy, which could come off as being kind of abrasive at times but he kept our group on track and our good grades reflected that. I would just ask that on both your parts that we put our "emotions" on the back burner and start afresh.
3GMAC - I can top your pain - try dealing with 16 attorneys (two of them Canadian) - median age 54 - whose idea of IT is an electric typewriter! I just finished giving a tutorial to my new SJA on how to use her aircard and the difference between it and the built in Wi-Fi she has on her laptop and then on to how to connect to the VPN to access the LAN from her home - it wasn't pretty!
BTW MacFloridaKeys- I checked on some websites and you did pay a hefty fee for that aircard as the plans I saw were very affordable with the aircard itself being free, if you took the 2-year, $60 a month data plan.
Again, good luck on finding a solution and I hope my attempt at mediation (can't help myself - I've been in the legal system too long) is successful
