No wireless access w/ 3945ABG

Question

I have an Inspiron running Windows XP with the Intel wireless 3945 adapter which was working fine until a week ago.  For almost the past year it has worked perfectly connecting to a Netgear router with WPA enabled.  Now, with no changes to either the Inspiron or the router, it no longer connects.  It sees the router and tries to connect, but will never get an IP address.  It will connect just fine with a cat 5 to the router.  At first I thought it was the router, so I reset the cable modem and router a couple of times with no luck.  Then I tried another laptop with the same adapter and firmware, and it connected just fine to the router.  Wireless range is not an issue since I'm in the same room as the router while I'm troubleshooting.  No filtering going on with the router, either.   So, I figure the problem must be with the Inspiron.  I upgrade the wireless adapter firmware to the latest version (no luck), disable McAfee firewall (no luck), and disable WPA on the router (no luck).  Any ideas, since I'm all out?    Thanks in advance. Message Edited by Bama1 on 04-21-2007 10:59 PM

try going to the intel site and get the latest drivers.   http://support.intel.com/support/wireless/wlan/sb/CS-010623.htm

Sorry, forgot to mention that. Updated drivers, too, with no luck.

when you said reset, does that mean you pulled out the power cord on both?

Bama1 · Answer

Yes, for both the modem and router, more than once just to make sure.

try putting in a new wpa code in the router and laptop.

I tried that as well.  Also disabled WPA altogether, but still nothing.

Have you reseated the card? If not try that a wire may have come loose. I don't know what system you have so I can't post a link. Also, you can boot to Safe Mode, then go to device manager and delete all network adapters then reboot. Wait for them to all reinstall, then try again.

Thanks for the help, guys. I haven't tried reseating it yet. I'll search the site for instructions and give it a shot.
