I have a few laptops involved here. Each seems to have different behavior which I think might help determine the problem.
- Windows 10 laptop with a wireless connection has been dropping unpredictably for several months. I have reviewed the Event Log, but found nothing useful that indicated a problem.
- Linux Mint 20 laptop (was running Windows 7, but recently decided to move to Linux rather than purchase a newer version of Windows). This one also has a wireless connection that drops unexpectedly. The interesting piece here is that the firewall reports connections coming from random IPs on ports like 53 (DNS) and 443 (HTTPS). It's also very suspicious that traffic is coming from 188.8.131.52 (Google's DNS server).
- Linux Mint 20 laptop with a hardwire connection. I see the suspicious traffic in the firewall logs on this machine also, but I haven't noticed any dropped connections.
- My work laptop (Windows 10 Enterprise) is hardwired and I normally don't notice any interruption when the Windows 10 wireless laptop has network issues. This might be because it is hardwired, or maybe it has firewall (or other) settings that are
- I have other wireless devices around the house that may be affected by this issue. My FireStick TV occasionally stops videos, and might be the same wireless drop.
