I am having similar issues but not with AT&T. In my organization I maintain about 85 Dell D-620’s and 50 Dell D-630’s. I have been experiencing the same issues with the computers locking up. The lock ups are hard and require the power to be cycled. The original Aircard that I was using was the Sprint Pantech PX-500. I moved all users to the Novatell Merlin S720 from Sprint and that did not help. I still experience lock ups with the new cards. I recently purchased two Verizon Sierra wireless cards and they also cause lock ups. The computers run fine when the cards are not inserted and as far as I know no one has experienced any lock up when the cards are removed. My organization has in excess of 2200 laptop computers, nearly all from Dell. My area is probably the only one that has a large number of mobile air card users. From speaking with other administrators they have not been experiencing any lock up problems. So I have pretty much narrowed it down to the PCMCIA interface. I recently put a Dell D-510 and a D-600 in service to test the air cards with these units and after a few days we have not had any issues. But it is still a little early to tell.
I have tried many different approaches without success. The problem I have is that the computers may boot up fine 3, 4 or 5 times without a problem, sometimes even more. Then there are those times that the computer locks up as soon as the PCMCIA slot is powered. I have had computers that lock up 20 or more times at boot up and then suddenly it boots fine. I also have had computers that boot fine most of the time and then lock up when in use. There is no pattern so it is very difficult to determine the cause.
There is also another issue that appears to be involving both the D620 and 630. The PCMCIA interface dies. This has occurred with about 16 of these laptops within the last few months. With Dell on site we have opened these computers and have found that the ribbon cable that connects the PCMCIA cage to the motherboard is coming loose. On 3 of these occasions the PCMCIA cage was defective and had to be replaced. The others only needed to have the cable re-seated. This seems to help with the lock ups for a short period of time but they do start again. I recently received back one of these same computers and I have not opened it so I’m not sure if is a loose cable again. I will post my results when I open it. The loose cable may be the cause for the intermittency of the problem and possibly even the cause for PCMCIA cage to fail.
As a last note, I have spoken with other agencies that use other brand laptops in a similar fashion with identical air cards and they have not had any trouble.

Dell will be releasing a BIOS update in late May to address this issue specifically. In the meantime they have confirmed that the issue can be resolve by disabling the Dell Wireless 1390/1490 WLAN card in Device Manager.
After spending a total of 3+ hours on the phone with AT&T (up to tier 3) support, and another 2 hours with Dell support, it seems that there's an issue with the use of this PCMCIA card and this new laptop model. After plugging in the card, the computer will freeze - no BSOD, no error logs, no warnings, pop-ups, nothing. The freeze occurs whether or not the AT&T Communication Manager is running or not, the Sierra Wireless Watcher program is running or not, after installing, uninstalling, and reinstalling these programs and the associated drivers. The laptop is brand-new, running Windows XP SP2, all drivers up-to-date. The Aircard works fine in other computers, including Dell Latitude D620, the predecessor model to this one. I can use the AT&T service tethered to my cell phone, and that works fine. Booting the system using selective startup with all services/ini files disabled does not make a difference.There are other reports of this on the internet, including one in this forum (http://forums.wireless.att.com/cng/board/message?board.id=pccards&message.id=9035#M9035).Because I was able to get a connection that lasted for almost a minute before freezing the system, AT&T determined that the card is "fine" and the problem is not covered under warranty. They wouldn't exchange the 881 for an 881U or 875U, despite my ability to show that a USB-tethered cell phone works just fine. As such, AT&T just lost my business. If anyone has a PCMCIA Aircard working on a Dell D630, or has figured out why there's a freeze problem, please post it here. If there are no solutions, avoid AT&T PCMCIA cards in Dell Dx30 laptops at all costs.-Craig

NOTE: The Wi-Fi Catcher feature is not supported with the Dell Wireless 1505 Draft 802.11n WLAN Mini-Card on the following systems: D820, M65, D420, and D620
