(Solved) Wireless-AC 7260 crashes, tons of event ID 50xx's, NDIS resets, etc.

[Nexus7]

Problem manifested itself about 6 months ago; the adapter would lose connectivity (minutes to hours after boot) and the Event Viewer would show hundreds of event ID 50xx's logged by netwnb64, usually followed by tens to hundreds of NDIS resets requested by the driver. Clean shutdown not possible at this point (Windows 10). Was running latest OEM (HP) driver and tried latest Intel drivers to no avail. Dozens of clean driver installs. Replaced module twice.

Fix: rerouting the Main antenna lead (2) so it "approached" the edge of the module perpendicularly (just like the Aux lead (1) was oriented) vs. running parallel to the edge of the shield (see below). The lead wasn't touching the shield, but there must have been some inductive coupling going on with it running parallel along the edge of it. Since making this simple adjustment, my adapter has been rock solid. Not one error logged over the past several days.

I hope this helps someone avoid all of the aggravation I went through!

Over the past several days the exact same issue has been plaguing my HP Envy x360 that I purchased about five years ago. None of the typical solutions found on the web improved anything. In my case, the wireless card was actually shutting down. The only fix, which was temporary, was to run the diagnostic tool in Control Panel, which would reset the card. That would work for varied periods of time but ultimately it would happen again. For informational purposes, here are the various things I attempted that did NOT work at all.

1. Turned off the power saver setting in Device Manager.

2. Update (or roll back) driver was not an option since there is only one driver available.

3. Reinstalled the device driver.

Those are the three frequent solutions found in most forums, which usually seem to fix other people's issues, but if they don't, it's a dead end. Thankfully I was able to find THIS solution, which did not work for my situation but did lead me to find what so far appears to have solved the problem in my case.

Radio signals for WIFI are usually pretty weak due to FCC regulations. ANY interference can mess up your wireless card's ability to maintain a solid connection. Thanks to the OP's post I took my HP Envy apart to investigate. While it is not really possible to reposition the antennae in these, I did find that during a previous repair I had carelessly failed to position a nearby wire AWAY from the antenna wires, on the other side of some plastic separators where it had been originally positioned. As a result, that wire, which happened to be the main wire leading to the monitor was parallel to the antenna wires. Monitor wires, I'm thinking, definitely emit a lot more EMF than the incoming WIFI signal would in the antennae. It has now been over a half hour and not one dropout has occurred. I hope I am not being too cocky in announcing my belief that the problem is now solved, but since it was dropping as frequently as every few minutes before I moved the monitor wires my confidence is pretty high that is exactly what was causing it.

Just to be sure I'll update tomorrow. If it makes it 24 hours without a drop, the problem is definitely solved. I thank Nexus7 for putting me on the right path. If it works that is. 😁
