Lets ask @Steve if he has any idea why the Speedfusion graph shows packetloss when the CAT12 modem is the only WAN in use, but p2p wan analysis using that WAN against the same Fusionhub doesn’t.
Also - the latest firmware (8.1.0RC1) has much better speedfusion graphing and is probably worth installing at both ends. Firmware 8.1.0 RC 1
