You shouldn’t have to change the ATA settings. You can verify that the device is set to DHCP by viewing the ATA’s SYSTEM tab. You will also need to note the HOSTNAME setting. The router’s configuration will assign the same fixed IP you specify based on the MAC address of the ATA. The MAC address of the ATA is found in the INFO tab (in the Product Information section).


I have a Linksys WRT54GS that’s running dd-wrt. I’m assuming the screens are similar.
  1. Go to the SERVICES tab.
  2. Under the STATIC LEASES section click on the ADD button
  3. Enter the MAC address (Each 2 digits are separated by colons, ie XX:XX:XX:XX:XX:XX) in first field that was found in the ATA’s INFO tab (see above)
  4. Enter a HOSTNAME in the second field (this needs to match the name on the ATA’s SYSTEM tab)
  5. Enter the fixed IP you wish to use in the 3rd field

When done click on Apply Settings then Reboot Router at the bottom of the page.
