But here something is not right, it looks like it either shorted or fell off somewhere inside:

How to properly unsolder such a connector?

Answer 1

Judging by the story, when the modem fell, it was plugged into the router. Most likely, the blow fell on the modem, and the soldering was mechanically damaged.
According to the story, it is not clear whether the modem works in another device (laptop, etc.) and whether anything works in this router connector. With equal probability, both the modem and the router could break.
The first step is to find out who died. Then - to disassemble and look. You can post pics here.

Answer 2

Open, visually see if nothing is torn off, not moved away.
Ring the port with a multimeter, for example.
Roll back to the checkpoint - toss it from the floor onto the cabinet.

Answer 3

Brain + hands + soldering iron

Answer 5

and cracks can also form on the tracks of the board, it is diagnosed by bending up or down with the power of the connector,
as an option (crutch), you can solder a piece of usb cable to the board contacts and let it hang outside the case, and plug the modem into this cable (literally a couple of centimeters long)
