Laptop has quit connecting to the Net. No idea why,
but it gives me the "Networking Disabled" notice
when I mouse over my connections icon.

Ubuntu 10.04 (with usual user of such an OS
suspicions mostly valid). The laptop is an HP
fairly new (less than a year old). Last time I used it
about a month ago there were no problems.

Today I started getting it ready to take to Montana
and couldn't connect to the Net. Same setup as
when I last used it, right here on the home network.

When I go to System Administration --> Networking
Tools, I get "loopback interface (lo)" same as on my
desktop that does connect. I have no idea why
networking is disabled or how to change that

Any suggestions gratefully tried.

In the terminal, I guess running ifconfig will only show you the loopback interface right? I'm also guessing you're using DHCP, so, you could try:

dhclient eth0

That's presuming you're using eth0, I think by quickly checking the man page that if you run it without any reference to what eth port, it will try all of them. That might be a start at giving you some idea why it's failing, or it should give you an address on eth0 (or whichever eth port is available). >From there... I guess it's then trying to have a look at why the network manager isn't doing what it should correctly.

That, and just checking your logs for anything suspicious.
