All networking stopped after months of happy wired, wirelss, or USB wireless. Now even after fresh install none of these work. Everything works fine in Win7 which is installed on second partition

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; rfkill list

Thanks

Thanks for the fast response. The above was run with my wireless USB plugged in, and 1 attempt at connecting to my wireless - WEP key correctly entered (it worked before this problem, works in windows and in a friends ubuntu). Just to clarify, I am probably missing the drivers for the wireless as I dont have them. Every ubuntu instal I've done in past I use a USB wireless then downlaod/install missing bits.

Below is response (means little to me im afraid ;-( )

Hi,

I followed the guide and had to manually download the files for ../pool/main/p/patch, ../pool/main/f/fakeroot and ../pool/restricted/b/bcmwl as they did not exist on my USB key (created using the guide on Ubuntu and used in same way to install previous working OS). It seamed to go well, everything installed but at the end of the guide I do not have any drivers appear in the "system>Admin>Add. Drivers". Anything else you can think of?

Ive attached another set of results that you asked for before incase something has changed for better/worse.

Use your wired link, makes life easier

Unfortunately none of that worked. Plugging in the same twisted pair netwrok cable that I had been using months ago (while it was working) does not connect me in ubuntu (works fine unfortunately in Win). I'm afraid its looking likely that I'll have to revert back to the dreaded Win7 as it just works, and I dont have the skills to get ubuntu working.
