Hello fellow Mikrotik users,
I have bought and installed this LTE antenna with a routerboard. After installation everything worked for test purposes. I got LTE signal automatically and it was enough for testing out the internet. When I was logged in in the webinterface, I got a notification, that there was newer firmware available for the LTE module. Given I always update my devices, I did that. I was on RouterOS 7.5 out of the box. The installation was successfull, but after that I lost my internet connection and was unable to make it work. I send a configuration message from the operator to the simcard. That did nothing. I manually edited the APN "internet" to the configuration provided by the operator and nothing. I manually selected the operator and nothing. I then updated to RouterOS 7.7 and that did not help either.
Has anyone an idea I could do?
Is it possible to downgrade the LTE firmware to an older version through this routerboard? If so, then how and where to get the files needed?
It is a remote destination in the hills around 100km away from the place I live and I am unable to connect remotely now. So my answers will propably take a while, as I have to drive there first a try something out.
Any help would be greatly appriaciated. Thank you
