I use an old wrt610n router which now has failing 2.4GHZ Wi-Fi, so I get another wrt610n to replace it.
I set up identical parameters in the new wrt610n.
All seems to work, except I can not contact it with the RRC-1258 MKii.
The URL is http://"my ip address":81/
In the Single Port Forwarding section of Applications and gaming I have :
External port 81, internal port 81, protocols BOTH (TCP and UDP), TO ip address 192.168.1.171, enabled. This is the same in both routers.
This works for the old wrt610, but page is not found on the new one.
What have I failed to setup?
