There is a radio bridge. Is it possible to buy the same 2nd one and plug a net into it in the city and send it to the dacha?

Question

Computer networks

Radio bridge Ubiquiti AirGrid M5-27.
The provider then offered this antenna and unlimited internet to the dacha. All nishtyak worked until he paid for the plate in full. Now, for 4 months now, net has been pinging worse than gprs. Constantly cut down, then for an hour, then for 2. In short, the provider cannot master this contraption, as I understand it.
Briefly speaking. Is it enough to buy exactly the same dish and put a normal cable net into it in the city, send it to the dish that I already have in the country and not enjoy the normal Internet?
Or do you need other equipment?
ps question about equipment. Not about visibility, range, muffled channel and other things. Here everything is in a bunch and everything is decided. It remains only to understand what to buy in order to make this important thing, like the human Internet.
Thank you for your attention.

Answer 1

Please note that for the legal operation of such a channel, it will be necessary to obtain a private permit for the use of frequencies in the SCRF, and if the devices have a power of more than 0.1W, then register them with Roskomnadzor.

Answer 2

If the admin panel of your device is not locked by the provider, then YES. Will work.

Answer 3

The radio frequency guys are coming for you.
