Hi,
I was just posting to see if anyone with a 2865lac has experienced problems with LTE after upgrading to firmware 4.3.2_BT.

I've found when using firmware 4.3.2_BT the LTE WAN works on boot as the fail-over kicks in (LTE WAN set as failover and ping to keep alive set) and the xDSL comes back online but I've noticed the following strange behaviour, before firmware 4.3.2_BT the LTE would terminate but still allow SMS messages and commands to be sent to the router ie. 'Router status' etc. but with firmware 4.3.2_BT you can no longer send or receive SMS messages/commands and the LTE status constantly shows 'searching network' after a while and LTE fail-over fails due to this condition.

To be clear everything works with firmware 4.3.1.1_BT and I'm able to send and receive SMS messages to and from the router and fail-over works but as soon as I upgrade to the latest 4.3.2_BT I lose the LTE WAN after a while and experience the problem as above.

I've downgraded the firmware to 4.3.1.1_BT as this is working for me as expected. I've already raised an issue with support and currently waiting to hear back.

Regards,
John
