I am trying to share the ethernet connection of my desktop with my laptop by creating a WiFi hotspot. I tried two methods :
- Software (Connectify, etc)
- Command lines ([netsh wlan set hostednetwork mode =allow ssid="ConnectionName" key="Password"] and then [netsh wlan start hostednetwork])
The WiFi network configuration works well but each time I connect my laptop I get a BSOD with error DPC_WATCHDOG-VIOLATION on my desktop. I learned that I had to debug the dump file C:\WINDOWS\MEMORY.DMP so I did it. Here is what I get after trying to connect to a Connectify hotspot :
The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL
Arg1: 0000000000000000, A single DPC or ISR exceeded its time allotment. The offending
component can usually be identified with a stack trace.
Arg2: 0000000000000501, The DPC time count (in ticks).
Arg3: 0000000000000500, The DPC time allotment (in ticks).

According to the line 'IMAGE_NAME: rtwlanu.sys' it seems that the problem come from the WiFi chip of my desktop. It is an external (USB) WiFi adapter (TP-LINK TL-WN821N). The chip number is RTL8192CU (Realtek).
Problem is: I checked on the Realtek website and the driver is up to date (the suggested driver is even older than mine).
How can I fix that ?
