Windows 10: Sporadic Wi-Fi issue - possible memory leak?

Hey all - I have an issue with my newly-built Win10 Enterprise system (v1803 build 17713.1002), although I've seen this happen with another Win10 computer I own using the exact same physical NIC.

Suddenly the WiFi will basically stop. Usually I cannot ping my default gateway, and no traffic passes. (Occasionally it just slows down terribly, local subnet pings are ~2,000ms.) The NIC is a D-Link DWA-192 with the latest driver.

Here's what I seem to have figured out: it appears to happen when I do large file transfer, whether to my NAS or to the Internet (MS OneDrive, this time). Running a ping window to the Internet with the -t parameter, I saw this today:

Request timed out.

It sure seems like some resource is getting exhausted during these file transfers, hence the ping time increases. It is sporadic and not reproducible every time.

Some additional information:

• I'm testing with a NetGear WNDA3100 now to see if it fails in the same way. That adapter is having a similar type issue, but it just drops to "General Failure" for a couple pings and comes back:

  General failure.
  General failure.

• The NetGear link actually drops sometimes, Windows says Not Connected and the pings go to "General Failure", necessitating that I pull the USB NIC and replug it to restore connectivity.

• My Wi-Fi indicator in Windows does not drop with the D-Link NIC, it tells me I'm connected and I still have an IP.
  
• I'm on an 802.11ac network by Aruba Networks, noise floor is clean on the channel and stats from the network side look okay. Other devices in my network continue to work just fine during these issues.

Any thoughts or troubleshooting tips? Willing to try just about anything at this point...

Thanks,
Mike

Possible Memory Leaks in Windows 10

A memory leak occurs when an application closes and fails to release all its RAM back to the operating system.

The first step in dealing with a memory leak is to determine which application is leaking memory.

The next step is to contact that application's technical support with complete details of the memory leak, since the developers will want to fix the problem ASAP.

 

Memory leak issue

The term "memory leak" means that an application fails to return all its RAM to the operating system when it exits. The leftover RAM is unusable to the operating system.

Step one is to identify the application that is leaking memory. Step two is to contact the application's developers and provide as much detailed data on the memory leak as you can. For example: which processes are still in RAM after the application exits
and how much RAM they occupy. Application developers never want their applications to leak memory and they will be grateful for the details you provide, particularly if they can replicate the leak on their own computers.

 

USB Wi-Fi Adapter Disabling

Is it on Windows 8's compatibility list (check MS website- forgot link)?

I had an issue with one Wi-fi adapter and it wasn't listed as compatible- All was well when I swapped it out with one on the compatibility list
