Bugcheck 9F Computer Shutting Down Instead of Standby, ndis.sys

Long time reader, first post.

Recently, Ive noticed my computer shutting down instead of going into standby. This seems to have started a few weeks ago, but I cannot pinpoint the root cause. The bugcheck report lists the error as:

BugCheck 9F, {3, ffffe0005473b060, fffff8022f66d990, ffffe00065e94c10}


Implicit thread is now ffffe000`54297700
Probably caused by : ndis.sys ( ndis!ndisPauseFilterInner+7628 )

Ive searched, but do not know what the cause is. I did a system restore to an earlier date last week and all seemed well for a few days, but the computer shutdown last night instead of going to sleep.

Edit: Im adding that the computer boots up fine when I power it back up and it will restart with no issues. There is no BSOD and the only way I know it shutdown improperly is when Chrome tells me it shutdown and if I look at the event viewer and see when the shutdown occurred.

Any help would be appreciated.

The Realtek network drivers have caused the 0x9F, if you are using any VPN software then it is recommended to update/reinstall/remove it.
Please update your Realtek network drivers

I am not talking about the Wi-Fi network drivers, but the LAN (ethernet) network drivers
The ethernet drivers are usually from Realtek.
