Is the Win 10 task bar crashing when it disconnects?

First...Open up the rear of the laptop, make sure both the white & black antenna wires are still attached to your wireless NIC card properly...some need to be white to white labeled nub/black to black. Just had a customers unit that had intermittent wireless...sure enough the unit was fine when it was on my desk near my router (About 1' away), put it (laptop), on my lap, no connections avail. at all....Someone had been inside it recently, neither wire was connected, both were sitting 2" away from the card itself. (1 of your antenna wires may be connected/1 disconnected from the Wireless adapter).

Is the Win 10 task bar crashing when it disconnects? (Have someone closely watch the taskbar for it to disapper and re-start or re-appear, and see if both that and your disconnection issue is related). If so, that points to a simple hardware driver issue (with the MS Win 10 Native Installed Drivers usually). Easy fix is usually track down which driver is causing the issue, and see if Hardware MFG Win 10 Driver(s) are avail....If not, try Win 7 or 8, or 8.1 drivers for that hardware item, see if the problem disappears).

Do you have AVG Free installed as an AV? (I upgraded a Win 8.1 laptop we have as a driver's Station -2015's, and a Win 7 Laptop we have as a backup Driver's station -2014 both to Win 10 to get them both simply matching in OS's, and they both already had all the 2016 NI software and all the updates installed on them before the upgrades). Both said all apps/programs, etc. were fully compatible except spybot S&D Ver. 1.62 of course...I always re-install that anyway.

The newest one - the Win 8.1 unit, had a hardware driver issue of some kind after the upgrade to Win 10 and the native Win 10 native OS drivers were installed, that I did not currently have the time to fully isolate...appeared to be graphics related though to me, and it was crashing & restarting explorer - It would crash explorer about once every 5-10 Minutes.

Then I installed AVG Free on it, restarted it, updated the AV, and went to sleep....finally. (I was going to figure out from the reporting system exactly what driver was causing the issue when I woke up later....But, I never actually got that far).

When I woke up later, and there were 7 NI files removed & in the AVG Free Virus Vault...AVG was so proud of itself saying "LOOK WHAT WE CLEANED OUT FOR YOU!"

I have never actually been furious of a working AV before....Usually they are my absolute best friends. (Later I figured out they were false positives, as I had previously run Malwarebytes, Spybot S&D, and Hitman Pro, and Windows Defender after the Upgrade to Win 10 and each found absolutely nothing).

I rolled that unit back to Win 8.1 immediately (only takes about 30 minutes), as it is done using the Windows.old folder created at the beginning of the upgrade, and uses a simple System Restore snapshot prior the upgrade....End of issues, the NI software was fully restored and unaffected, all 7 files that were in the virus vault were back in their proper places. No more explorer crashes (no taskbar restarts)...I'll deal w/ upgrading that unit to win 10 after the current FRC season ends.

Currently, we are now running the programming test bot (drivetrain w/ CAN, compressor and 1 air tank storage, etc.), on either laptop -Win 8.1 & 10 (Tethered USB or Ethernet, or wireless), now that all of the firmware (RoboRIO, OM5P-AN Radio, and PCM has been all finally flashed & properly configured, and the roboRIO was formatted (ran the self tests), and test code was finally deployed -Using Labview. (We faced numerous repeated mDNS connection issues w/ both laptops occasionally on that path, and had to switch back and forth between laptops to get all of that successfully done though).

Seems like that is a problem with the new mDNS auto IP feature...We are still investigating what is causing that situation to develop occasionally - connecting to begin with usually via USB, not disconnections, as it just assigns each device an IP, and when we switch from tethered USB to Ethernet cable or back on the Laptop NIC, it won't simply release and assign a new IP or return to automatic reassigning of IP's to devices switching between USB, tethered or wireless...even with a laptop restart). It says missing a necessary network setting...but, does not specify what network setting is missing upon running the network troubleshooter -states problem is not fixed!

Simply switch laptops...And immediately we are back in business.

Weird science!
