maratsade,
Thanks -- since you are eastern time and you first noticed the issue 6:30pm last night (9/2), it is apparent that we started to experiance the issue at different times. The issue did not start for me until I rebooted shortly after 8pm eastern time. From the graphs you can see my performance was excellent before 8pm (except for a short heavy rain at 5pm).
The issue causes intermitent connections because the satellite signal strength is all over the place -- so everything is working then when the SQF drifts too low there is a loss of connection for a few seconds while reassociating to the gateway.
Under the System Status screen, the 'Satellite Receive Signal Strength' value is the SQF in the log -- do you see your value jumping all over the place, or has it settled down to a constant value for you?
Thanks!
