Can't connect to router - first time setup SXT LTE6

RouterOS Beginner Basics
1

I recently bought a SXT LTE6 but Im not able to get it working, I connected the antenna to the injector and has a green LED on but the data port on the PC connected does not detect it, I have tried changing the speed to 10 / 100 but nothing, I tried two different NICs (one USB ethernet adapter and other PC) with no luck. Also performed a reset, changing IP config to static 192.168.88.x/24, dynamic, nothing works

It is not mounted yet, if that matters, so Im kinda lost because I checked some videos where they have it connected like this so Im not sure if Im doing something wrong (first time using mikrotik) or if the injector may be faulty

Any help is welcome,thanks

Found the issue, the cable connected between the antenna and the injector is not working, I tried swapping it and now the PC port is up. Somehow the power was working and the cable is fine because it works when connected to other router
