I've never seen a problem with two simultaneous connections. My desktop
came with a wireless card and is connected via Ethernet and wireless as
I type this. It's also a common situation when setting up or
troubleshooting wireless connections.
You say, "...wireless icon in the bottom right of the
 screen shows a connection to my ISP with excellent signal
 strength.", but it's probably showing a connection to the wireless
device, which is not the same.
The next time you see this, reset the modem and that might fix the
problem. You can also rt-click and "repair" this connection.

Thanks David, that did help. The fact you wouldn't normally have to
 "do something" to swap between Ethernet and wireless 
apart from disable the wireless made me think something
 was odd with my Fujitsu. 

I did a "restore" to a date prior to the Ethernet use and the 
wireless was back again. I then made sure I had disabled wireless
 and went back onto the Ethernet and then back onto wireless 
and everything worked as it should.

This implies the Fujitsu can't "handle" a wireless and
 ethernet internet connection at the same time - which seems reasonable.

However I don't think it should require a "restore" if inadvertently 
the Ethernet cable was connected whilst the wireless was enabled. 

Any idea what happens with other computers if the this is done?
