I have read the threads about the Dell Inspiron 6000 and the Verizon PC5740 cards. I've experienced all the same problems (such as the card doesn't finish installing, or it installs but says it may not work - it doesn't - and it hangs the computer when shutting down). I've talked to Verizon for days (got a replacement card, that doesn't work in this machine either) and I've tried to talk to Dell, but haven't gottne anywhere yet. I've tried a system restore, I've disabled drivers and start-up processes, and I've uninstalled McAfee, all to no avail.
I'm running XP Pro, Service Pack 2
I first got the card about a month ago, and it worked ok on first install. Then it started disconnecting me after just a few seconds, then it stopped working all together. Verizon sent a new card (I have both) and now I can't complete the install on either.
Has anybody seen this problem and found a solution to it?
