Despite update to 5.3.3 sounded like the reboot issue was about to be gone, the reboot after updating to 5.3.4 failed again for both PAB(WLE1216v5-20) and A(SDIO)B(WLE1216v5-20).
Yet the bigger issue is Wi-Fi SSIDs do not come up for both WLE1216v5-20-cards. Therefore I need to rollback and maybe have to do a troubleshooting sometime in the futures as I do not have the time right now.
Did anyone else install a WLE1216v5-20 in his/her MOX and SSIDs came up just as expected after this update?
