I have RB433UAH with routerOS v.5.14
I'm using a ZTE MF626 3G USB stick.
It works fine until there is a power outage. If (after a power outage) the router boots with the stick inserted, the USB port comes up invalid (in ports it is in red) and the connection does not work.
If I remove the USB stick and reinsert it it starts working again.
If I manually reboot the router while the stick is working when it comes up again it works fine. The only problem is if the router is rebooted by a power outage while the stick is inserted. If that happens manually rebooting the router after that does not fix the problem. The only way to solve it is to remove and reinsert the stick.
I sent an email to Mikrotik support 4 days ago along with the suppout file but there is still no answer whatsoever.
Can someone here assist in solving this?
