Yes device froze while being on Auto and Manual bands selection.
For PSU it’s connected directly in my motorhome to LiFePo battery on 13,2V.
The connection is ONLY WiFi as its mounted on the window and is not reachable with cable.
The device became unreachable in the middle of downloading a picture from mobile phone to computer (via WiFi ridiculously slow - 7Mbit/s-that isn’t normal. With Huawei I was getting 25+Mbit easily).
It was still showing me that it was connected to WiFi while it became suddenly unreachable and had to be restarted manually. Even after waiting for 5 minutes, the WiFi was not available and I had to unplug it.
That is not even consumer stable, not to mention industrial stable.
Never in my life, I had to unplug and plug back any router to restart it. Neither did none of my routers stop working just in the middle of downloading.
