First, from System Information, skip down to Network Service, and make sure Telnet and FTP servers are enabled.
Then exit out of that, and go up to INTERNET.
I assume that it doesn't give you an IP# there, or you would have seen it when you were at System Information..... IF it DOES give an IP#, then it's possible that your network was actually working and you didn't have FTP enabled, so you might try using Filezilla again. But, assuming that it doesn't give you an IP#, then
(A) If you know what the IP#s of the computers on your LAN are, then you can choose Static IP, and enter a unique IP# on your lan, ie one that isn't the same as your router or any other computer on your LAN. You will also have to enter 255.255.255.0 for the SUBNET {mask} , and you'll have to enter the IP# of your router as both the GATEWAY and DNS1.
(B) If you DON'T know the IP#s in your LAN, then hopefully you have a router with DHCP enabled, so you should select "Dynamic IP" in the second line. With that checked, the router should give your Azbox a valid IP#, and set the other parameters.
After doing either A or B above, then go down to the bottom and select SETUP.
I can't remember what happens after hitting SETUP, but after doing that, you should be able to do a speed check, and if you go back to System Information, it should tell you your IP# there, and it should also tell you Normal(Connected) to the right of Internet Status. If it does, then try Filezilla again.
