I had a similar issue with my Jynxbox M1 Pure Linux box. It would connect then disconnect, but it would work at my workplace on WiFi just fine even though the router was further away. I ran across an antenna modification where you move the taped antenna from the lid more to the front of the box, and that solved my WiFi issues.Quick update.
I managed to get it to connect to wifi but it quickly lost connection and wouldn't connect again.
It's not a signal issue.
The box wouldn't take the wifi password any longer.
Tried switching to xios skin but still wouldn't workeven after a reboot of the box.
I do have an Ethernet wired connection issue where the box gives me no connection errors so I was hoping to try this Pivos firmware to see if that might help things. I've tried both M1 firmwares posted at the start of this thread, but when I click apply upgrade and select the file there comes up a signature verification error all the time. Is there a trick to this? I saw someone else flash their Jynxbox M1 successfully. Do the M1 files end up with recovery menu boot problems where the recovery menu comes up all the time?
What I've done is with the power unplugged, I press in the upgrade button, replug in the power adapter, wait about 10 seconds for the android/box picture to load after the green screen, and then choose the upgrade option. I notice that there is a message at the bottom of the screen that shows that uboot was not found. Do I need that file on the microSD card somewhere?
