Since internet seems to work a assume that 
1) for the ping its a routing problem. When you type "netstat -r" you should
get something like:
Table de routage IP du noyau
Destination     Passerelle      Genmask         Indic   MSS Fenêtre irtt
Iface     *      U         0 0          0
eth0   *        U         0 0          0
default         UG        0 0          0
exceptc that eth0 sould be ppp0 for you and wlan0 should be eth0.
if you are missing the first route you can try adding it by hand
run as sudo:
route add -net mask
(if nothing works after remove the rule with route del -net

2) for the ssh issue is sshd running on the other machine?
try /etc/init.d/ssh start (as sudo).
BUT TRY FIST FIX THE PING ISSUE. Cause your line timed out.

when there is no route to host the connection times out. thus first try to
fix the routes
