Hi,

Please, don't "cross-post" between lists unless it is strictly necessary 
(I don't think this is such case ;-) ), it's a mess because users who 
follow Debian list could not be following the replies you get on the 
Ubuntu one (and viceversa) so we can miss information.

Can you please tell where is located the wireless adapter for where 
connection is dropped, on the connecting machine (client) or on the 
connected one (remote server)? 

You said "local router"... does it mean the client side? If yes, you can 
do some debugging, for example, restarting the networking service 
(instead rebooting) and retest the connection.

Are you using NM to manage the wireless interface? If yes, you can 
monitor the logs in real time (as root, "tail -f /var/log/syslog") to 
gather more information on the disconnection.

OTOH, are you sure the above steps are the only pattern that triggers the 
failure? I don't see the relation between using MC to get into "/etc" 
directory and loss the wifi connection :-?
