I've been facing frequent disconnects like other MR models. Signal strenght is 100% and router to my device distance is not more than 3 meter.

So far I've tried following steps.

1. Creating custom network profile
2. Setting 4G only mode
3. Setting channel number to 1
4. Setting DNS to 8.8.8.8 and 8.8.4.4
5. Disabling firewall
6. Setting channel width to fix value. (tried both 20MHz & 40MHz)

None of these worked. Also disconnects doens't happen at fix time, it's random. Something it happanes twice in a minute.

So far I've seen only following text in the log when disconnect-reconnect happens.
