I wouldn't have thought that to be the cause. Pseudo-privacy by changing MACs (and thereby probably changing the assigned IPs) should only happen between when new connections are made. It doesn't happen in the middle of an established connection. And that alleged anonymity is going to be immediately broken by you reconnecting to the same thing as a few moments ago. It'd be why connections are dropping that you need to fault find. Bad networking cables, WiFi transmission problems, router failing, unreliable ISP, etc. It could be a coincidence that it started with a new kernel, but you can easily test that by trying an older one (or other device). -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
