I need help debugging a w2k-pro machine. The machine runs fine when connected to my LAN using a 10-base-t cable. The problem is that when I use either an SMC 2536W-AG or a Netgear WAG511 Wifi PCMCIA card, it crashes.

Can there be a software problem that crashes when the PCMCIA cards WiFi card is in use, but doesn't matter what brand/model of WiFi card it is ? Perhaps some fix for PCMCIA or WiFi in general, not the specific card ?

I can use it for days with no problem with a cable connecting it to my LAN, but when I put in either of these cards and use it, I get crashes (BSOD.)

The last three crashes today were shortly after I started using the Netgear card:

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000001e (0xc0000005, 0x8046a988, 0x00000000, 0x4a00828c). Microsoft Windows 2000 [v15.2195]

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000001e (0xc000001d, 0x01aafc09, 0x80449cb4, 0xc8758536). Microsoft Windows 2000 [v15.2195]

The netgear driver I've been using is : WAG511 Version 4.0 March 18, 2005.
There is a newer diver for WAG511 that is updated for Vista, but it was released so recently I'm reluctant to try it.
Version 5.0 (supports Windows Vista) Published June 20, 2007

The SMC driver is dated 11-10-2003, Driver version to, utility version to v3.01.

This machine is:
* IBM Thinkpad T21 (circa 2001)
* 512 meg ram
* new Toshiba drive MK8032GAX 80GB ATA/6 Notebook Drive 5400rpm 8MB Cache 9.5mm SuperSlim.
* McAfee VirusScan Enterprise Workstation Version 8.00.1009

I love the keyboard and the screen. I recently got a new battery and replaced the disk drive.

Thanks so much if you can help me.

Try uninstalling the SMC driver and utility and use the Netgear Smartwizard software instead... I have a Netgear W511T on a Thinkpad T23 and it works fine.

Thank you - that's exactly what I had done. I had uninstalled the SMC driver and utility software, rebooted, and then installed the Netgear Smartwizard software (WAG511 Version 4.0 March 18, 2005) before I posted the message asking for help.

The machine was well behaved for an hour and then crashed again when I inserted the LAN cable:

8:00 PM
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000001e (0xc0000005, 0xbfd95a5a, 0x00000000, 0x0000002c). Microsoft Windows 2000 [v15.2195]. A dump was saved in: C:\WINNT\MEMORY.DMP.

So now it crashes without a PCMCIA card in it.... I do have a Sierra Aircard 875U (USB wireless internet modem) from cingular that I used for a while before I inserted the LAN cable... so even a networking card on the USB conector (with a mini-hub) seems to lead to subsequent problems.
