[ubuntu-uk] some user losing internet access

[M Castle]

well... thats quite a comprehensive answer!

Thank you, Chris.

ok: the machines with the problems are both hard wired.

wireless has no problems at all with the internet, and so I'm assuming have no 
relevence to the hard wired machine's intermittant connection.

admin accounts have no internet interuption. only user accounts, so Im 
assuming it's software in the OS itself.

the wireless machines are customers, so I couldn't tell you the hardware they 
are using, but as I said - they have no problems :/

the box's in question are used in cafe's around bristol.

there are six, all in different places, but only two have problems (that I 
know of).

and yes - I am using network manager in gnome to connect automatically.

Given all this (and the reason for my confusion with the problem),

1> can't be hardware/drivers because the admin account runs ok.
2> interference? i'm not using wireless - and anyways the admin account stays 
connected ok
3> not wireless managers (not wireless)

which leaves me with software. what could give a an intermeittant conection on 
a hard eth cable line for only some users (non admin ones)?

sorry - hope this is clearer than the last mail and that you understand my 
problem a bit more - i need to practice making these things clearer - but I'm 
getting better (i hope)!
