There is a lengthy PR with various theories for this:

My personal theory nowadays (after trying different "fixes" posted for other
OS): it's a chipset bug in the old variants of ViaRhine. Just avoid this
hardware wherever you can. I've seen all OSs I tried lock up their network
connection with this hardware from time to time.
