Sql developer - not able to establish connection

I am using Windows 7. While creating the new database connection, I selected the connection type as 'TNS' and role as 'default'.

The Network Alias as 'orcl' which was an option in the drop down menu. I gave the same name in the 'Connection name' .

I gave the username and pwd and saved the connection. Now when I try to connect, it gives me the timed out error.

I am new to SQL and I did these steps after seeing a video for the same on youtube.

The control panel shows the startup type as Automatic and status = started for OracleServiceORCL.

What do i have to look for after typing the commands? The command 'lsnrctl status' completed successfully.

The command 'tnsping orcl' did not return any such message. The last stmt on the command line was 'Attempting to contact.....'

Windows firewall is not enabled. It is not using the recommended settings, I am trying to fix that.

Thanks for your help.

The output from 'lsnrctl status' is -

The windows firewall is not working on my computer. Is that causing this issue?
