Hi,

I once had a similar problem using linux. I could use the
connection a while but then it just froze. 

If you are having a slow connection then you must lower
the mtu (Maximum Transmit Unit) and the mru (Maximum Receive Unit).
Probably it should be enough to lower the mru.
For a modem connection a mru of 296 should do it.

You can't do a netstat -r if the connection is "down" because
it tries to resolve domain names. Use netstat -nr instead.

Alex
