[Solved] Network disconnected after suspend mode

[silentlion853]

I am using Linux Mint 19 Tara x86_64. My problem is after logging in from suspend mode all networking is disconnected (internet and vpn). My connection is via ethernet and the only way to re-establish my network is to either reboot or shutdown. When I reboot everything works okay. Is this a bug in 19? I had no such problems with 18.3. Thank you.

I had the same problem. I fixed it by removing NetworkManager and setting up my NIC in /etc/network/interfaces, like this (switch enp5s0 to match your NIC):

Code: Select all

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto enp5s0
iface enp5s0 inet dhcp
iface enp5s0 inet6 auto

Thanks for the quick response. Had to reboot the system after saving the changes, then everything worked like a charm. Thank you.
