[Rack] nb network down or awry and...

[jim]

hiya, 
    you may already know that on the morning of 
Monday 20110926 the nb network is down, or at 
least the wifi portion is not working. 
    there used to be a wired connection between 
the network and the turing classroom, and that 
seems no longer to exist. 
    i have time to do physical work tomorrow, 
tuesday 20110927, and would like at least to 
reconnect a cable so's the turing classroom 
can connect to the network (i.e. gateway out). 
i don't want to "just do stuff" to get something 
to work; instructions and/or someone available 
by phone tomorrow afternoon will be a help.
