Mint 13 Mate Problems with Second NIC

[differential]

I am running Mint 13 Mate on an HPMCP61HM-PM Nettle 2 Motherboard with an Athlon CPU and 1GB of RAM and want to install a Realtech RTL8139 network card for a local LAN. The internet is connected to the on-board network. I can't configure the Realtech card and the following may explain why. There appear to be two Realtech drivers and the two NICS are swapped and then swapped back.

I am about at the end of the road with this motherboard. It has been a lot of trouble but would be grateful for any input to what I can do to sort this rather than installing a new motherboard.
Thanks
Russell
