Thank you both for your suggestions I have tried them all but still can't connect to the internet.

I am wondering if there might be something wrong on the hard disc that is not related to the ethernet card or the network software because when I boot with the USB stick, the network settings are identical with those when I boot the computer from it hard disc even to the extent of having both 8139too and 8139cp and the same interrupt in both cases. Also, I have just booted it with a live CD of 9.04 alpha 5 and the settings are the same and I can connect to the internet. It is just when I boot from the hard disc that the network problem arises. I have noticed that the settings ( in Network Settings and Network Tools) are all greyed out.

If I could update the current alpha 4 to alpha 5 perhaps the issue might be resolved but trying to do it with the Alternative CD won't work and I can't think of any other way of doing it without an internet connection.

I think perhaps it is time to admit defeat and reinstall Ubuntu!

Whatever. Reinstall looks easy at this stage. Use a stable version.
ll your settings greyed out could be permissions, missing bits, or dodgy ardware.
try these

sudo ifconfig eth0 down
sudo ifconfig eth0 up

That will tell you if it's hardware.

Thanks for that business_kid. When I did that I got a response saying "64 bytes from icmp_seq=127.... ttl=64 time=0.052ms". The number after icmp_seq kept increasing. Presumably that means that the hardware is OK?

When I disconnected the ADSL modem to write this on a computer that works properly the output changed to "Network is unreachable"

The Network Manager icon still said "No network connection" during this.

Anyway, although I still have no connection on that machine I have learned a lot of things that I didn't know before, so thank you and farslayer for all your time and patience
