LTE DEVICES - Slow LTE reconnexion

RouterOS General
1

Hello,

I use many of your LTE devices (LHG/LHGG/Chateau12/Chateau5G/Wap etc …).

I have experienced a very fast LTE reconnection with the Chateau12 since the RoS V7.6. Like 3-5 sec to reconnect when the LTE signal is lost. But very very slow reconnection with other devices (LHGG for exemple).

I’ have tried to upgrade an LHGG with the lastest modem firmware (V027) and the last RoS V7.1RC1, same time to reconnect (30----45sec).

Do you have an idea to reduce the delay for all devices ?

No informations ?

LHGGR have got a R11e-LTE6 and SoC who is core of LTE have very slow re-connection times.
Best is use at*cell=0 to do faster re-connection at this lte card, we not discover anything faster.

at*cell=0 is ~20s
enable lte1 is ~45s

Thanks you SiB.

The best is using the netwatch ? Like ping 8.8.8.8 with 1000 ms ?
