Is there a fix or firmware update for the Sagemcom 5866T modem.  This device appears to have substantial issues out of the box.  Key issues are: Displays incorrect information in the user interface Does not maintain a connection, and requires restart several times per day Does not detect a loss of connection (i.e doesn't fail over to 4G) Signal display and connectivity lights on the front of the modem are not consistient with the actual behaviour of the modem. I have been suffering with the device for some time, my analysis has determined that the device has substantial issues and in my opinion is not ready for production use.  Please let me know if you are also having similar problems with this device.    In advance of the L1 'helpdesk questions' Yes the modem is correctly situated.  When it is working correctly after a restart the device throttles down to the 100/20 speeds as advertised. There is no Wifi issue, the behaviours are consistient whether connected by Ethernet or Wifi, 2.4GHz or 5Ghz. Yes its been restarted (hundreds of times) No there is not a useful log, the Sagecom log is very high level and the device doesnt usually detect that it has lost connectivity. Yes the solution is repeatable, when connectivity is lost, or speed drops to kbps a restart generally re-establishes full speed. Hopefully there is a firmware fix to solve the problems, otherwise I'll need to get TPG to supply a different model. The service is currently not fit for purpose.     ... View more
