NetWorx was working soooo good. Then suddenly yesterday morning it stopped monitoring the router.
I was using the portable version. Installed the latest non-portable version. Rebooted the notebook. Rebooted the router.
Disabled wireless on the notebook, went to wired connection. Will not see the SNMP or UPnP. Will work with 'all connections' and 'Ignore local traffic'.
Was working with UPnP for months on this Sagemcom 1704N modem/router. Rarely missed a beat. Now, nothing at all.
The UPnP monitor utility mentioned in this thread shows traffic.
