NetWorx has been working fine on my main computer. Now I want to use it on my second PC to monitor my FRITZ!Box 6591, but it doesn't work.
I read all topics here about FritzBox, but nothing helped.
Unfortunately, there is nothing we can do about a specific router. Basically, in order to be monitored, a router must support SNMP or UPnP and expose the WANCommonInterfaceConfig service. If it does not support either of these, such router simply cannot be monitored.
Please check our Router Monitoring chapter of the user manual and refer to your router's documentation to find out which (if any) technology is supported.
