[SOLVED] I sometimes get BAD_POOL_CALLER BSOD when creating a wifi hotspot

[vladmoraru97]

I use the program Virtual Router Plus to create a wifi hotspot on my desktop and connect my phone to it for game streaming. I'm using this wifi adapter here https://www.tp-link.com/us/products/details/Archer-T2U.html
Most of the time it works. But sometimes, when I open the hotspot program and click "Start Virtual Router Plus" to create the hotspot, I get a bluescreen with the error BAD_POOL_CALLER.
The wifi adapter I'm using has two hardware versions and, thus, two different drivers. I'm not sure which hardware version I have, but I tried both drivers and both have this issue.
I used driver verifier, but it didn't find any unsigned drivers or drivers built for older versions of Windows.
I used WhoCrashed from www.resplendence.com to analyse the crash. Here are the results:
Crash dump directories:

crash dump file: C:\Windows\Minidump\010719-22328-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x153FA0)
Bugcheck code: 0xC2 (0x7, 0x1200, 0x4020009, 0xFFFFE0013FAB1C20)
Error: BAD_POOL_CALLER

Bug check description: This indicates that the current thread is making a bad pool request.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

some driver attempted to free pool that is already free.
(pool is just the name of data in memory shared by device drivers)

this would be a bug in the device driver.

since you have a USB adapter you don't know if the problem is with the wireless driver or the usb ports. you would want to update the bios, update the motherboard usb drivers for any external usb 3 chipset then update the motherboard cpu chipset drivers to get ubs 2 port updates.
then look for a update to the usb wireless driver.
looks like the most current one is dated 2018-05-30

I think this would be the chip manufactures driver for that device:

it depends on the hardware version of the device, they might use different chips for different versions of the hardware.

I actually got a couple bad pool callers because of an outdated wireless card driver so it might be that.
