According to that image, it would appear that it *is* a modem+router. Note that it says the current mode is "routing" and has a button offering to change it to "bridge mode" (aka, modem only).

If it's in router mode, then yes, it would be the renew/release option since it is the primary router. If it's in bridge mode, that option should not normally be available since it’s no longer the primary router.

Can you provide more information on your router FTP configuration?

The FTP Server setup is pretty straight forward, but without additional information on your setup and any error messages your FTP client generated when it fails to connect to the F7D7301 router, it will be difficult for others to assist in troubleshooting your particular setup.

Some general comments, avoid having the Public and Private root directories pointing to the same directory on your USB storage device. If connecting to the FTP server from the local network the FTP client software should be pointed to the Belkin router's IP address (the default address is 192.168.1.1). If the FTP server is configured for WAN access, the FTP client software (via the Internet) should point to your WAN IP address. Note: The WAN/Internet IP address may be assigned to your broadband provider's modem/router. If the Belkin router is attached to an upstream router, you may need to configure the upstream router to forward port 21 (FTP port) to the Belkin router.

Attached are some screen captures that show a sample FTP Sever configuration on my Belkin N300 F7D7301 router that works both internally on my local LAN, and from the WAN (Internet). Note: due to my broadband configuration I have disabled the DHCP server on my Belkin router, enabled Use WAN port for LAN on the Belkin router, and have configured my broadband provider's router to forward port 21 to the Belkin router. I did not have to configure port forwarding on the Belkin router. In this sample configuration the USB storage device is called "KODAK". You'll note that I have the Public Root Directory pointing to "/tmp/mnt/KODAK/public/", while the Private Root Directory is pointing to "/tmp/mnt/KODAK/". Note: when using User Accounts, you can point them into specific folders off the Public Root Directory by specifying that directory in the User Account Root Directory field for that user. Or if you set a User Account Access to Private, they will be pointed into the folder (if one has been created) named after the User Name for that account in the Private Root Directory.
