Networking :: Installing RTL8139C
Netcardconfig gives an error: no supported network cards found. "modprobe 8139too" doesn't work. System stats says unknown realtek device.
If it's a pci card, then the following commands should give you some info which may help you along:
lspci
lspci -v
lspci -vv
lspci doesn't give anything useful. Just "Unknown device 8111"
"modprobe 8139too" doesn't find device.
