Windows 7: BSOD driver_irql_not_less_or_equal windows 7 when plgging LTE Dongle

BSOD driver_irql_not_less_or_equal windows 7 when plgging LTE Dongle


I have Windows 7 Professional with service pack1 (Lenevo)

Intel -Core i5 -2450 M -CPU@2.50 Ghz
64 Bit OS

Windows installed some 1.5 years ago. No Errors or problems so far

Problem: I have two LTE Dongles when i now connect them i get the BSOD error "driver_irql_not_less_or_equal windows 7" I donot get this error when i connect these dongles to the other laptop (hence concluded the device is fine). These two dongles used to work fine on my laptop as well.

So i deduced this is driver problem. But the device is installing the drivers every time i plug in the Dongle.

Now when i connect the same type of LTE dongle (Borrowed by my friend it shows error while installing on two devices) attaching the screenshot of the error.
BandLuxe WideBand Ethernet Adapter #4
HSPA-LTE NDIS Adapter1 -Data.

I deduced that when i connect my two dongles then on the above two steps they throw the BSOD. whereas on the other devices they dont. But what I couldnt do is undo the drivers or settings of my two dongles. and hence posting this thread.

Please Help

Note: Pls help with the step by step instructions. As the suggestion like uninstall driver. do not help as i donot get a listing devices since BSOD comes up as soon as i plug in the device.

Hi All,

No More BSOD. I am Closing this thread.
Uninstalling the old drivers helped solving the issue.

But i am facing the Issue i faced with my friends Dongle. i.e. Ethernet adapter is not installed.
Though i am able to use the dongle but not as ethernet. (minus of which i cannot share my connection using virtual router). Now will raise another thread in appropriate location to get help.

Thanks for Help.
