I purchased the balance one and have migrated from the 20. All went according to plan.
With the new setup… I notice a few times during the day the router is sensing a loss of connection to my comcast WAN… but only for a few seconds at a time… typically 5 seconds or less. I have attached an image of the event log and also, in case it is useful, a shot of the modem’s connection stats (after running for 3 days).
Does anyone know what the likely cause of these disconnects are?
