This seems like there are issues with the network card driver. It would be helpful to know what kernel modules and what NIC you have (e.g. with lspci -nnk | grep -A2 Ethernet) and what kernel version you are running (uname -r).
 
Do you remember the name of the NIC it showed at the beginning?
r8169 no other option

Yes that is a NIC that has had its fair share of Linux driver/kernel problems.
Is your system fully updated?
Search these forums & you'll find enough info on this subject. Maybe start here.

Sorry I can't help more - I don't use that NIC currently.

Good luck.
