Windows 10 RDP connection ping timeout every 10 pings


In our lab I have 5 identical desktop computers with a wireless network connection (all same brand/same model/same software/bought on the same date)

We normally connect to these using RDP.  4 of those work absolutely perfectly. The 5th has a weird problem:
If I connect to this desktop computer using RDP and start a ping -t servername in a command window (on that desktop computer), every 10th ping either gets a "request timed out" or has a very high (>3000) time value while the others typically have 2 or 3ms.  This results in serious lag when using our engineering software.

What could be the problem? Anyone have any ideas?
Who is Participating?
Could be the hardware (switch), the software (same software on all machines? personal firewalls, security suites?), or a driver (same NIC driver everywhere?).
i would guess it is a problem of the wireless router. if that is true the problem would vanish if you connect the computer by wire or move it closer to the router.

generally wireless connections share the bandwidth of the router and therefore are second choice for desktop computers.

1. Use cable... Results?
2. Update drivers. Results?
3. Temporary turn off your firewall and antivirus. Results?
4. Try clean boot without services and startup items. Results?
5. Go to Settings -> Network and Internet -> Status -> Run Network Troubleshooter (while your issue occurs) following by these commands:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

6. Go to Settings -> Network and Internet -> Status -> Network Reset -> confirm
7. If the issue persist, the solution is to choose another channel on your WiFi router (use WiFi Analyzer to determine which channel is less used) or switch to 5GHz.

I switched the USB Wireless network dongle with the pc next to it (which didn't have any problems) and the problem persisted.
Then reinstalled the driver on the problematic pc and now it seems to work.

Never had that happen before: usually with driver problems it either works or doesn't work, but this time every 10th ping packet was either timed out or very very very slow.

Thanks for the comments.
