NOTICE
If an S&C SpeedNet™ Radio is being used for the field area network radio, the
remote Web user’s computer will require an additional setting to be updated to
enable Web access . The user must reduce the MTU (maximum transmission unit)
size to a value of 500 or lower . It is recommended to use an MTU size of 500 for
optimal performance . To change the MTU size, the following command can be used
on a Windows 10 machine:
netsh interface ipv4 set subinterface “Local Area
Connection” mtu=500 store=persistent.
