I have a TC8305C modem. I want to change a computer to a reserved IP. When I follow the instructions in the modem guide:
"How to assign a reserved IP
Proceed as follows to do so:
1 Browse to the Admin Tool.
For more information, see “Accessing the Admin Tool” on page 25.
2 On the left menu, click Connected Devices.
3 The Devices page appears. If:
Your device is already listed in one of the tables, proceed as follows:
1 Click Edit.
2 The Edit Device page appears.
3 In the Configuration list, click Reserved IP.
4 If needed, change the value in the Reserved IP Address box."
and then click Save, I get an error message "MAC address already exists". The MAC address is carried over from the values already entered. It will not Save the changes.
