I am using Ubuntu 12.04 64bit on my desktop and my laptop. Have install openssh client and server on both of them.

My desktop is connected to ADSL2+ Router TD-8840 with wired connection and has 192.168.1.1 IP address.

My laptop is connected to 150Mbps Wireless N Router TL-WR741ND with wireless connection and has 192.168.0.1 IP address.

ADSL2+ Router TD-8840 and 150Mbps Wireless N Router TL-WR741ND are connected with a wired cable by useing blue port for on wlan on TL-WR741ND.

I can connect to desktop from laptop via ssh with no problem,

internet connection on laptop and desktop is working fine,

but when I want to connect to laptop from desktop via ssh in terminal I type

ssh [email protected]

and get

ssh: connect to host 192.168.0.101 port 22: Connection timed out

If anyone is able to point out whats wrong?
