Traceroute from the desktop shows no hops. They are connected to the same router with a wire. Could the problem be that I have two IPs and two network interfaces, and I am not binding ssh service to the right one? I want to be listening on 192.168.2.136, the wired connection.

couple things to try.
first, /etc/init.d/sshd status
to confirm it didn't segfault.
if that's not the case, reply and include the output of (on the netbook):
iptables -L -n
ifconfig|grep -B 2 inet|awk '{print $1"\t"$2}'|egrep -v
'(inet6|LOOPBACK|127.0.0.1)'|egrep [0-9A-Za-z]|sed -e 's/inet//g'
and the contents of /etc/ssh/sshd_config
lastly, a traceroute (from the desktop) to the IP address(es) in the
above ifconfig.
additionally, (from the desktop) an:
ssh -vv (<user@>)<IP address of netbook, see ifconfig)
would help as well.
