wired Etheret not detectd

[stan]

My long suffering laptop died, so I went and bought a cheap ASUS, and
installed 12.10 on it. Everything "just worked", including the wireless
networking!!

Then I wanted to plug in the hardwired Ethernet connection, only to find out
it was not listed in an ifconfig -a. This is the first time in years that I
have seen hardwired Ethernet connection not "just work. 

Any suggestions as to what I need to do to make this work?
