Need Help in Getting Wired Networking to connect

I have Haiku 4.1 Nov2012 running on an older Compac desktop. It all goes well except that it doesn’t find the wired connection. There are two connections available and I don’t know how to select either in Haiku?

Pref>network> chooses a connection I don’t recognise…I am using a ‘live’ CD to make sure it is going to work before installation…it works OK on a laptop but not the Desktop.

Can anybody direct me towards how I can select the right wired connection?

@kim1963, thanks, your guidance got me going in the right direction…I found it necessary to isolate one of the connections to get it to work.

You help was essential and much appreciated.
