Excuse me, I'm a beginner and I don't understand much. Could you give me a small diagram of how I should make the connections, I will be very grateful.

Measure the voltage delivered by the router source.
If you deliver 12V to 12.5V, there is no problem in connecting the (+) of the battery with the (+) of the source and the (+) of the router.
In addition, you connect the (-) of the battery with the (-) of the source and the (-) of the router.

Do not worry, they are two valid ways to do it, the two at the end achieve the same purpose

Once the project is done and you take the corresponding tests, the result is super positive, now the problem is that since the router is installed in a country house when I arrive at the place, I realize that the power supply and the router work with 9v, now the question is: Would it work the same with the reley (HELISHUN HLS8L-DC12V-SC) of 12v 5 or not correct? Thank you very much for your advice.

Hi, if it could work with 9v

If the battery is 12V and the router source is 9V, you could damage the router by applying 30% more voltage.
To avoid damaging it, you can lower the voltage with 4 diodes in series. With the scheme you don't need a relay.
