wAP LTE kit - Ping passes, but periodically loses internet connection

Fri Sep 20, 2019 12:30 pm

Hi! I have problem with wAP LTE kit - periodically loses internet connection, but ping passes from PC and router too. The RouterOS update utility writes: No route to host. This happens with a frequency of 15-45 minutes. After rebooting device or after turning off / turning on lte modem the internet connection appears.
Router OS 6.44.5 long term, modem firmware CP_2.160.000_v012, I tried other versions, but this did not solve the problem.
