uninstall filezilla and download and reinstall it again and try that
other than that, you may need to flash the box as it looks like it's password protected - I've seen a few of these, suppliers lock the box so only he can add lines etc, the only way around it is to flash it again if this is the case....I'm just saying it's a possibility
EDIT
if that is the ip address you are putting in then it's not surprising you can't connect.
the IP address of the box isn't 192.168.1
