Question Need help on BSoD: DPC_WATCHDOG__VIOLATION I've tried everything.

[shakirjam96]

My laptop is having said problem specifically when connected to my home wifi. I'd reformat the laptop. I'd analysed dump file using windows debugger said an issue with my wlan driver so I removed the laptop's wifi card & used only usb wifi dongle but the problem still persist. https://1drv.ms/u/s!AtmFnUq8vggggbxVdyOrsIJmC6VAkA?e=3GzWol this is the latest memory dump file I have not yet analyse it, I would be much appreciated if fellow forumers could analyse it & give your input on what really happened. thank you.

BugCheck: [DPC_WATCHDOG_VIOLATION (133)]
Probably caused by: memory_corruption (Process: System)
Uptime: 0 Day(s), 0 Hour(s), 02 Min(s), and 35 Sec(s)

Comment: 2 or more types of RAM are installed.
That is pretty normal on a laptop, did you add any extra or its how it came?

4096MB	2133MHz	Samsung	M471A5143EB0-CPB
	0MHz
4096MB	2400MHz	Micron	4ATF51264HZ-2G3B1
	0MHz

not sure its normal for them to be 2 different speeds though.

what is the make/model of the dongle? I can see if I can find newer drivers

rtwlanu.sys

Realtek WLAN USB NDIS Driver https://www.realtek.com/en/

Could use Ethernet, I can find newer drivers for it, possibly

rt640x64.sys

Realtek NICDRV 8169 PCIe GBE Family Controller driver https://www.realtek.com/en/

download Win10 Auto Installation Program (NDIS) from under windows header here - https://www.realtek.com/en/componen...0-1000m-gigabit-ethernet-pci-express-software

I’d reinstall my old wifi router which is not wifi 6 & connect my laptop to the wifi, the problem didn’t occur, no bsod whatsoever but then I’d reinstall back my wifi 6 router & connect my laptop to the wifi then the bsod reoccured. I’d updated my laptop wlan driver to latest version but no avail.

So the wifi card in Laptop uses Realtek Drivers, and the Adapter does as well.
From what I can tell, the card in the latop used these drivers - https://www.realtek.com/en/component/zoo/category/rtl8188ee-software
the ones for the Dongle are at least 2 years newer

neither the card or dongle are Wifi 6 so you not really benefiting from using the faster router.

You would need something like these to get faster speed from the router - https://www.asus.com/au/Networking-IoT-Servers/WiFi-6/All-series/filter?Category=Wireless-Adapters

It seems common that the BSOD you get happens when trying to attach realtek adapters to Wifi 6.
can be caused by bad config on the router

Well the solution is rather simple, turns out that when I change the authentication type of my wifi security from WPA3-PSK to WPA/WPA2-PSK the laptop connected to the wifi with no any problems/bsod.

https://fixmytech.com.au/dpc-watchdog-violation-blue-screen-on-telstra-wifi/ Referred to this.

My router's manual said this.
"WPA3 has the strongest encryption among these with the increased cryptographic capability and the requirements of the Protected Management Frames (PMFs) to help prevent snooping attacks." so yeah disable WPA3-PSK then the matter solved. I appreciate for your help @Colif
