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.
Sorry. I did it because the server is debian and my laptop is ubuntu,
but I guess I should have stated that in the original email.

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)?
It's the local client machine that I'm connecting from that loses its
wireless connection.
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.
Yes I lose the connection between my laptop and my home router. I meant
rebooting the router, not my computer. What happens is the wireless
drops completely, and won't reconnect until I reboot the router. I don't
know how to restart just the networking on this router.
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.
I've already tried this, but don't know enough about what's happening to
interpret it much. I've pasted below what comes up in the syslog when
the error occurs.
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 :-?
There could be other things that would cause the error - that's probably
just how it's shown up because it's something I do often. If I do 'cd
/etc', and start mc from there, it works fine, and continues to work. I
haven't yet managed to work out the boundaries of what makes it drop and
what doesn't. E.g. sometimes I can do what seems to be the same thing,
and it works differently.
Here is a copy of /var/log/syslog on my laptop from the point that the
terminal session hangs, through the wireless dropping, to when it gives
up trying to re-authenticate to the router. The first line in the log is
at the point where the wireless drops, which is a minute or so after the
terminal session freezes.
