I'm unsure if this is hard or software issue but I really need to find out.
I was running Windows 8.1 for some time, then swapped to Linux mint with kernel 3.13 which worked fine. I updated kernel to 3.19 without issues. Later I swapped to 4.0.
One day, my network stopped working, (eth0) does not matter if I'm docked in station or using a cable. (this is at work, so we have many desks that I use..) Swapped to Elementary OS, 3.16 - Same issues.
I tried to downgrade kernel, update my network drivers, update NetworkManager etc. Nothing works.
I have checked:
- logs (syslog)
- New kernel
- New drivers (updated grub, initramfs)
- taken traffic dumps which shows broadcast traffic and my outgoing (but no other incoming) traffic
... etc I cannot find anything interesting, the interface shows traffic being sent out but it does still not seem to leave my computer really.
Currently I have a script that brings eth0 down / up and restarts dhclient which is the only solution that works.
IPv6 is disabled on all possible levels. wifi does not have this issue!
Network: Card-1: Intel Ethernet Connection I218-LM driver: e1000e v: 2.3.2- port: 4080 bus-ID: 00:19.0
I'm also using VMware and bridge to eth0 for my virtual windows. (tried VirtualBox and VMware, does not change, so I don't think they ruin my eth0 connection)
Anyone have any tip on how to troubleshoot this further? Only thing I know is to install windows again and see if it has the same issue (in case of HW failure) but that's a buttload of work right now.
