odd network error - wireless drops when browsing with mc over ssh

[andy baxter]

Hello,

I've been getting an odd network error when trying to work on a remote 
computer over ssh. What happens is:

- I log in to the remote machine using ssh.
- Then su to the root user.
- Then start midnight commander. (mc)
- Then navigate to the /etc directory using the arrow keys. (By going 
back up the tree then down into /etc)
- When I press the right arrow key to go into /etc, the terminal window 
shows no response, and shortly afterwards the wireless connection to our 
local router drops.
- After this has happened, I am unable to reconnect to the router again 
over wireless until I reboot it.

If I change to /etc before starting mc, the problem doesn't occur, even 
if I then return to the root dir and go back into /etc.

This error has happened pretty consistently in the way I describe about 
6 or 7 times now. It doesn't happen every time I do this, but when it 
does, the error always occurs at the point where I try to go into /etc 
from the root dir. The only significant thing to have changed on the 
remote machine is that I recently upgraded it to run debian squeeze.

I don't really have much idea where to go from here, as what is 
happening is outside what I understand of how the relevant protocols are 
supposed to work. Any suggestions on what might be happening, or things 
to try to diagnose the problem further, would be much appreciated.
