The device, 1 week old, keeps restarting itself under load.

I have tried both after the firmware update and with factory settings, neither cures the problem.

Over speeds of 3-5mbps (downloading a file for example) it hangs on for 5 mins at first, then starts the reseting loop.

2 devices maximum are connected at time, problem keeps happening on PC, doesent matter if connected over WIFI or charging cable (ethernet)

settings are 2.4Ghz, network mode set to 4G+

Device itself is not hot or anything, Ive googled the problems so far and none of the stuff helps.

Looking forward to help.
