Frequently Asked Questions

Question: What can I do if the USR8200 Firewall/VPN/NAS can't obtain an IP address from my ISP?


  1. Make sure that your cable or DSL modem is connected properly.
  2. Try unplugging then plugging back in your cable or DSL modem in order to reset it.
  3. If you are using dynamic IP addressing, make sure that your cable or DSL modem is DHCP-capable.
  4. Some ISPs require that you use a registered MAC address. If this is the case, you can use the Clone MAC address feature.
Question: What can I do if the specified installation procedure did not work?


The Reset Button restarts the USR8200 Firewall/VPN/NAS or restarts with restored factory default settings. The button is located on the back of the router and is recessed to prevent accidental use. You will need a paperclip or other small tipped object to reach the button.

  1. To restart the router, simply press and release the reset button.
  2. To restart the router and restore the factory default settings, press and hold in the reset button. The PWR indicator will turn red, the WAN indicator will blink, and the USB1, USB2, and 1394 indicators will start turning on and off in sequence. When the USB1, USB2, and 1394 indicators are all simultaneously green, release the reset button. This will restore the original factory default settings and restart the router.
