Solved Problem with WAN Miniport (IKEv2)

June 18, 2018 at 06:59:04
Specs: Windows 7, 32bit, Intel Core i3-4005U CPU @ 1.70GHz
My laptop goes sometimes spontaneously in a BSOD. I THINK there is a driver problem with WAN Miniport (IKEv2), because that shows a yellow exclamation mark. When I ask to update the driver, the laptop starts to search on the internet and then goes to my laptop and finds a driver, but it says DON'T INSTALL THIS DRIVER, probably because it is not signed.

The laptop has been to my PC shop, but they did not find a solution to the BSOD. So I took it back to try and find a solution. I have been looking for a program that can localise a corrupted or wrong driver, but did not find one.

I looked on the internet and found that there are a number of entries complaining of the same problem, but I found no solution.

Help would be greatly appreciated

A repair installation of win-7 may resolve it all.

Are important personal files already safely copied to external media?

Not familiar with that problem - but... and this is a very long shot...

Power down, remove battery too.

Remove RAM sticks and clean edge connectors with a soft pencil style eraser; wipe edges clean with a soft lintless cloth (a kleenex may suffice). Re-insert one stick - firmly , then remove it and re-insert a second and then a third time; and leave it there. Do this which each RAM stick in turn. Do not use anything even mildly absrasive to clean contacts.

Power up and see if the BSOD still occurs...

Reasons for remove/re-insert three times is to clean the board socket's edge contacts to.

RAM can occasionally cause BSOD when the sticks are either slightly displaced and/or the edge connectors become oxidised...; and cleaning as above removes that oxidation...

As I say it's a very long shot but it has been known to resolve all manner of issues in the past...

Go to the laptop manufacturer's website & download the WAN Miniport driver. Don't have Windows try to find it for you.

As for the BSOD, the info on the screen should provide what you need to search, troubleshoot & fix the problem. If the blue screen flashes briefly & then the system reboots, try disabling the auto-restart feature.

Cleaning the memory stick did not change things. BSODs keep coming

I had already been looking for the Lenovo Wan miniport driver on their site. But there is no possibility to search for a WAN Miniport driver. There is a possibility to auto update, but that doesn'nt work. When I ask Windows--> control panel --> device manager and right click on the WAN Miniport driver and then choose to UPDATE DRIVER, I end up with a driver with a warning not to install it, because it is not digitally signed. When I do try to install it, it fails.

When I look at the info on the BSOD it shows different files that cause it each time it happens

Is the only option to re-install win7 and download all the updates ? Or is there something physically wrong in the machine and the problem continues eve after re-installing, something the PC shop suggested ?
