I have a Thinkpad X61 duo core 7673CCU and have been using Windows 10 Pro without any problem until a recent Windows update after it kept crashing with error stopcode netwlv32sys "Driver iqrl less or equal". It says my drivers are updated and I also ran a memory diagnostic test and sfc /scannow with no errors. A Microsoft agent support said rolling back to 1511 version instead of 1607 Anniversary might help so they ran a media creation tool but after verifying the download the option to keep my files was greyed out saying I might have an 'unsupported version'. Then I lost the agent. Would appreciate any suggestions on how to go back to before the update was installed or how else to fix the crashes? Any manual Lenovo drivers that would work even if they aren't meant for x61? On system recovery it says I cannot go back to an old build because 10 days have passed. On the event log under the crash it says 'bug check 0x000000d1 (0x935ac3c0, 0x00000002, 0x00000000, 0x92c8096c). 'Thank you.

The netwlv32sys file is part of the drivers for your laptops Intel PRO Wireless 3945ABG PCI Express Mini Card, and it does not appear that a driver has been released for it since Windows 7, and thus I doubt one will be coming that supports Windows 10.
If everything else is working fine other than the WiFi adapter, You can probably uninstall the card via Device Manager (making sure to check the box to "Deleted drivers software for this device"), reboot and go directly to the BIOS/Setup and disable the onboard WiFi Adapter and stop the BSODs,
The X61's Intel WiFi card is a PCI Express card that "could" be removed and replaced, but I believe that Lenovo had a whitelist of cards that could be installed on the X61 that prevents you from installing a newer model WiFi card, so you are kind of stuck with obtaining a Windows 10 compatible USB WiFi adapter such as this one.

Unfortuntely it is not possible to uninstlal the Anniversary Edition after 10 days have passed; and after that period you would need to essentially need to start over and reinstall Windows from scratch. Individual updates can be uninstalled via the Programs and Features control panel, but it sounds like the update that caused your problems was the Anniversary Edition update, which was a major OS change..
Are you getting the "IP Not Verified" in your browser when trying to connect.is current adapter, or the the USB Adapter, but check the following. If so, you might try the following

Is the crash information (STOP Code) the same, or is it a different message? Microsoft just released Windows updates this week, so it may be related to a new update.
If you can, please attach a small memory dump to a reply, so it can be viewed to see what is causing the BSOD, or if you a place to upload the larger Automatic Memory Dump, it will have been written to the C:\Windows folder and named MEMORY.DMP Once located, upload it and provide a link.

The next time your system Blue Screens, it will write a time and date stamped file into the C:\Windows\Minidump folder which is small enough to attach to a reply using the Choose File option in this forum.
