For the past couple of weeks, my computer has been crashing with a DPC_WATCHDOG_VIOLATION blue screen shortly after I log in and open Opera GX. It often crashes several times before Windows becomes usable, and I also get occasional crashes while watching YouTube. The problem began suddenly, without any hardware or software changes.
I have updated my network and graphics drivers, reinstalled the relevant software, and run System File Checker. WinDbg did not clearly identify a faulty driver, but several minidumps appear to implicate my NETGEAR A6210 USB 3.0 Wi‑Fi adapter. My onboard Intel I219-V Ethernet adapter is disabled, and I currently do not have an Ethernet cable available, so the A6210 is my only way to get online. Is there anything else I can try, or should I replace the Wi‑Fi adapter?
System specifications:
CPU: Intel Core i7-9700K
GPU: NVIDIA GeForce RTX 2060
Wi‑Fi: NETGEAR A6210 USB 3.0 adapter
Ethernet: Intel I219-V, currently disabled

The A6210 is the strongest suspect. USB Wi‑Fi drivers can cause watchdog crashes when they spend too long handling deferred procedure calls, and your crashes consistently happen during network activity such as opening a browser or streaming video. Updating the driver does not always resolve an underlying compatibility problem.
The cleanest test is to unplug the adapter completely, re-enable the onboard Ethernet device, and use a wired connection for a day if possible. Simply disabling the adapter in Windows is not quite as conclusive as physically removing it. LatencyMon can also help identify which driver is taking too long while a video is playing.
The minidumps point more specifically to the A6210 driver than to the generic Windows wireless components. If a clean reinstall and the newest available driver do not help, the practical solution is to stop using that adapter and test with a different network device—such as a replacement USB adapter, an internal Wi‑Fi card, or a temporary Ethernet connection. Make sure the old adapter is physically unplugged during the test so its driver cannot trigger another crash.
So even though the driver is up to date, replacing the A6210 may be necessary if I cannot get it stable with a wired connection?
I suspected the A6210 too, but I do not currently have an Ethernet cable, so I cannot test with a wired connection. I already tried updating and completely reinstalling its software without success.
