Optus AC800S does not automatically reconnect to mobile network.

I've been using AC800S on Optus wireless as my home internet since January 2019. I get great speed when it's connected, but it has been having problem staying connected ever since I got it. It has multiple disconnections everyday and the worst thing is that the router doesn't reconnect by itself. It doesn't even show that the connection is down. Every time I have to restart it manually, not even a disconnect/reconnect on the web interface can get the connection back. I did update it to the lastest firmware earlier but it didn't help with the disconnection problem. I am waiting for Optus to get back to me on this. In the mean time,  has anyone else been experiencing this?  I'm getting more and more frustrated with it. If it's not for the good speed it has when it's working, I'd have returned it months ago.

    Hi,

    Have you tried disabling Band 3? I've been reading a bit about these recently, and it seems they're prone to random resets which may be mitigated by disabling B3.

      Hey thanks for the suggestion. I actually set it up to only use band 40. That way I can get 3xCA on b40. It's fairly quick when it's working. I can get 40mbs even at busiest time around 8pm.

      I just had another disconnection. It's a bit different this time. It actually had the disconnected alert showing on the modem and on the web admin. however there was nothing I can click to reconnect. The only thing worked was choosing a different APN and switch back to the default one.
