[Nottingham] wifi weirdness

[stripes theotoky]

The problem:

Have tried to connect to the wireless  with two different laptops running
Linux, Ubuntu 12.04 LTS.  One is a Samsung N150+ notebook, the other a
Lenovo ThinkPad W520.

The problem occurs only with the work wireless.  Ipad and windoze laptop
connects fine.

Both machines have been connecting with no problem to airport wifi, home
wifi, or at friends.

The computer that is giving problems is a Samsung N150 netbook.
The operating system is a fully updated version of the latest LTS release
of Ubuntu running Gnome.

The computer will connect perfectly happily to a 3Com router in staff
accommodation so ultimately connecting to the university network and to
3Com at home, Billion and Netgear routers at friends places. The only other
system it refuses to connect to is Skymesh at mother in laws.

I have a Lenovo with the same version of Ubuntu on it also fully updated
which connects just fine. So far as I can see the settings are the same on
both boxes.

WPA2 Enterprise
Protected EAP
CA Certificate none
PEAP version automatic
Inner authentication MSCHAPv2

Either I am overlooking something simple in the settings or there is some
voodoo I really don't understand.
