WMP54G RT2500.sys Driver causes BSOD Error: driver_ irql_ not_ less_ or_ equal

[ Edited ]

Trying to install WMP54G v4.0 on XP SP3.

I have tried all three PCI slots.

Removing driver RT2500.SYS system will boot.

Put it back and BSOD Error:driver_irql_not_less_or_equal

Uninstall and reinstall in safe mode, if it doesn't work try a different version.

Problem resloved with Ralink driver instead of Linksys.

I physically removed my Linksys WMP54Gv4 from the PCI slot to get the error to go away.  It's better than the BSOD I was getting at startup at the moment. 

 

Clearly I still hope to regain wireless access so I'm going to try to fix this by installing the Ralink driver.  I don't really care for lmgtfy URL's - that just seems a little too noob...  Why not a direct URL to Ralink?  Seriously, if you're gonna make the effort to post - why not make it actually useful.

 

I'm in the process of trying this site:

I'll post again if it actually works.

Re: WMP54G RT2500.sys Driver causes BSOD Error: driver_ irql_ not_ less_ or_ equal

My solution was to roll back to the 2004 driver. Unfortunately, I don't see that driver here on the site. It came with the original WMP54G v. 4.0 disc, installation software version 4.3 I believe.

 

Windowx XP 32bit SP3 fully updated as of 8/03/2010

 

using driver:

 

rt2500.sys 118kb 4-22-2004 12:09am

Rt2500.INF 14kb 4-22-2004 12:08am

rt2500.cat  8kb 4-22-2004 12:08am

This actually worked for me (I am on XP) and I got it from http://forums.majorgeeks.com/showthread.php?t=185955

 

Before beginning make sure you download version 4.1 drivers from Linksys site (because it surprisingly also has version 4.0 drivers that actually work):

 

http://homedownloads.cisco.com/downloads/driver/WMP54Gv4.1_20051117.exe

 

1. Go into safe mode

2. Go to device manager (right click My Computer, Properties, Hardware tab, Device Manager)

3. Expand the Network Adapters Tab and uninstall anything that says WMP54G

4. Reboot back into safe mode

5. Run the appropriate setup for your card's version after unzipping the .exe above to a folder

6. Restart back into normal mode

**************

OK - I have tried this twice - both times, I'm apparently getting caught in some kind of loop.  It's been "stuck" on 25% of the installation for a couple of hours.  Ideas? I followed the directions above, uninstalled all the linksys stuff, etc.   I'm in safe mode, I'm the setup using the application in the driver folder, I am installing the software before installing the pci card as the directions stated.

 

Frustrating.
