I have both eth0 and wlan0 actives, can ping both, can run RDP to both IPs (192.168.0.101 for eth0, 192.168.0.102 for wlan0).
Ssh to eth0 works OK, ssh to wlan0 works OK as long as I have eth0 connected to the router. If I disconnect eth0 and run ssh (Putty, from windows) it hung after typing password. Wlan0 respond to ping, RDP works ok. :/
If I run a sudo service ssh status on my RPi I get that the session is opened.
