There may be things at home that you think you can do without help. The Internet does not work and you fix it, with basic knowledge. But be careful with touching the router, the cable, the patch cord, the socket... There are cases in which it is better to be patient, cases in which you should call a technician and not take care of fixing the Internet yourself because you can spoil it even more and make it more difficult.
Therefore, it is best that we do not experiment ourselves and try what works and what does not and that we let someone with experience check it and solve it in the best possible way.
I want to change the site router
You may want to change the site router because you have done work at home or simply because you have made a change that needs to move it. Nothing happens if you move it one meter and the cable arrives, for example. But if you are going to change the room, this is complicated because you may damage the fiber cable and be left without a connection.
Can you move it? Power you can move the rosette but you may have problems because the fiber cable can be easily damaged by bending it and trying to wind it, you can make knots or folds that will make it not work correctly. In this case, the best thing you can do is call to see if changing the location router is an option or if there are better alternatives if, for example, you want to change it because there is no coverage in a specific room and it is solved with a repeater.
