IRQL_LESS... BSoD with multiple wireless cards

Okay this is about to drive me to tears...

I have XP Home on a SOYO MB w/P4 1.8Ghz CPU/512MB RAM box

After getting the DRIVER_IRQL_LESS_THAN_OR_EQUAL error over and over after
installing a Linksys 802.11g PCI card and Linksys being less than helpful I
took the card back and got a Microsoft 802.11g PCI card... lo and behold,
the problems continued!!

With the linksys card the error referred to a file bcmwl5.sys, with the MS
card it refers to a file mn720-50.sys.

So...
1) I've reinstalled XP... same problem occurs
2) Managed to update XP with all fixes/SP1 etc... same problem occurs
3) Checked that ALL drivers are signed (sigverify)... they are but problem
STILL occurs
4) Completed an intensive memory test on my RAM... guess what... yep, same
problem
5) No, the CPU is not overheating

Okay, now what?? The drivers are up-to-date; the card is not sharing IRQs
with any other hardware; I've moved the cards around to no avail...

I am going absolutely nuts with this and am about to just dump the MB/CPU
to the highest bidder!!

ANYBODY GOT ANY IDEAS???????

Thanks,
Mark

To respond, just add the @ sign before yahoo and obviously add the .com on
the end...
 
actually both Linksys and MS use the Broadcom chipset (and the base
drivers are the same) so I'm not surprised that you have the same
problem with both cards as they are pretty similar. that said, it is
likely a hardware issue here and not a driver issue. could be a power
supply issue.

you might want to try one of the hardware groups on this one.
 
Okay, that would probably explain this... however, I really think it
must be a driver problem now - the error occurs EVERY time I try and
transfer files from my main pc (w/XP Pro and connected to a linksys
router and westell dsl modem) to the problem pc. I get the error
practically IMMEDIATELY. Not sure where to go now... are there earlier
or later drivers that I can try (maybe generic Broadcom drivers?)
 
Okay, so now that I knew it was the broadcom chipset/driver that was
probably at fault, I went in search of others with the same problem. It
didn't take long - a guy on a forum had reported the same issue with an
HP/Compaq wireless unit with the broadcom chipset - he had fixed it with
a new driver release from HP. I figured what the heck - couldn't hurt
to try those drivers and lo and behold they worked a treat... NO MORE
ERRORS!!!

My suggestion would be for Linksys and MS to update their drivers so
more people like me don't run into these issues...
 
This really could be a power supply issue. I really recommend the
hardware groups. Broadcom does not make generic drivers available. I
do not think it is a driver issue.
