eth0 Connection fails on boot

Post by Hillybilly » Mon Jan 22, 2018 1:49 pm

I carelessly deleted the efi partition on sda1 (didn't notice gparted reset from sdh1). Everything is back except
the network connection wired on eth0. The dual boot linux connects but then I don't have my setup OR I
can boot my setup without the network.
Reinstalled network-manager etc. Everything looks set when inspecting files and using lshw -C network, lspci,
ifconfig eth0, ufw off, and many others (but there is no dmesg log in this profile).
netstat -i says eth0 1500 0 1903 0 0 0 394 0 0 0 BMRU
ss -s says Total: 545 (kernel 0) TCP: 11 (estab 0, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 0.
I don't know how to read these.
fing says I can ping it but that's about all. Is this about the driver not loading Kernel~4.4.0-83-generic? But then netstat -s suggests (to me) below its all running however no repository, apache or firefox connection is made. OTOH on boot I see "Failed to start: Raise network interfaces" and lsmod says kernel module e1000e is used by 0.
