After 16 days of running in High mode, Avalon needed a reboot. Unplugged and plugged again the power and just reboots all the time.
Made factory reset, still the credentials didnt wiped out, and now its just rebooting.
Update: Now its working stables without rebooting but works only in Low and Medium mode, until 65. The fault is the GAN adapter, Lenovo runs smooth non stop 24/7.
Same here, nearly every two weeks or so I need to restart my Avalon Nano 3 due to the problem that it reduces hashrate to something like 123GH/s. After a reboot and some Low/High changes it works again.
