EDIT: see post #3 first (BREAKING), a live USB stick with LM 19.3 produces the same faulty behavior.
notes:
I'm talking about WIRED connection, LAN, ethernet, apparently related to an atheros ethernet card.
I've checked the problem PC with :
21.3 Virginia (kernel 5.x), LMDE 6 (k6), DEBIAN 12 (k6) -- the same "thing" happens.
I also have another machine at hand with LM 21.3 XFCE and the problem doesn't happen.
That machine has a different ethernet adapter, of course. (Realtek 8111/8168/something)
Whereas this machine (the problematic machine has: Qualcomm Atheros AR8152 v2.0 Fast Ethernet (rev c1)
-----------------------------------------------------------
I have 2 SSDs, one has Linux mint 20.3 the other 21.3, dual boot...
the machine has Qualcomm Atheros AR8152 v2.0 Fast Ethernet (rev c1) (built in an Asrock board)
So, I can say that:
the same machine works fine with LM 20.3 but produces LAN problem after sleep with LM 21.3.
Instead of LM 21.3 XFCE 64 bit, I have also tried LMDE 6, and DEBIAN 12 -- with the exact same results.
What happens:
LAN works perfectly. The "Connection has been established" messages pops up as usual...
Then sleep, and after sleep it takes a long time for the network manager to get the connection. but even when that happens, it is not an actual connection... i.e. no connection to the internet.. (browser doesn't reach the internet, ping command doesn't either)
Just after boot, I can disconnect and reconnect "WIRED CONNECTION 1", it works perfectly, within a second, quickly.
After sleep, it takes a long time, but when it says connection has been established, it doesn't work....
There are no IP addresses obtained.
Weird thing: I boot to the other "instance", the 20.3 machine, and all works well.
Network Settings also appear to be identical (speaking of 20.3 / 21.3)
I hope this can be worked out...
thanks very much for your help in advance....
please tell me what details you need in order to be able to help...
