Hi everyone, and a quick thanks to waterhead (I think that was the name) for his post on extracting as much info as possible from your system before presenting a network problem on the forum.

Where to begin? This is so bizarre. I installed intrepid for a friend a while back (this is cross-distro stuff - it even affects his xp installation as well) and all had been good. Yesterday he tells me he was in his Yahoo email account, when the app asked him to log out and back in again. I know James, and there is no way on God's Earth he would have been doing anything out of the ordinary. Anyways, he does as instructed and finds that he can't log back in again. In fact he can't log into any site on the net that requires him to login. Hotmail, Yahoo, Facebook...all of them ain't playing. Anything that doesn't require a login, fine. So I flushed firefox of ALL private info, cache, cookies - everything, and nope. No joy there, still no logins allowed into sites on the net.

So I pasted the routers IP address into the address bar of Firefox, pressed enter and was taken to the opening page of the router configuration stuff. Which follows:

Belkin router

OK. Its a start.

I then ping the router using the same IP address used to access the above. Ping fails. Odd, that. So for some unknown reason I changed the last number in the address from 1 to 2. Pinged that - as expected, it failed. But then I changed the 2 back into a 1. Pinged the original IP address again, ping succeeds. Eh? To make sure I wasn't dreaming I went back and repeated the exact same process with the exact same result. But whatever, lets be grateful that the ping worked. Went back onto the net, same problem persisted.

So, enter lsusb, lsmod and uname -r

from uname -r

2.6.27-11-generic
Straightforward vanilla kernel I believe.

from lsusb - the usb stick he is using is a 3com. I copied this from the back of it (naturally enough he hadn't kept all that tedious packaging and information that came with it)...3CRUSB10037- anyways from lsusb

Oh dung. Seems I had only copied pasted a section of the output. Whoops, my bad, but I think the relevant line is in the mix (I hope so, and my apologies):

OK, with all this I thought about my personal time issues (he had failed to tell me that XP was totally borking with the net until afterward my next move (he is a computer user, after all) and decided, as he had everything backed up, that a re-install of intrepid would be the quickest route forwards. So, wiped the partition, reformatted it as ext3, then let the ubuntu installer loose on it. Logged in went on the net and...same problem. Then, and only then do I find out that XP was borking.

Deep breath.

Anyways, the connection is shared between two windows machines and his dual boot machine.

Any help would be very, very welcome, and thank you in advance for anything you may do to help. LF
