Which router to buy?

Question

WiFi

I am faced with the choice of a Wi-Fi router for the home. The speed at the provider's tariff is 700 Mbps.
I want to squeeze the maximum speed out of this Wi-Fi tariff. Therefore, I look towards Wi-Fi 6 AX.
The distance to the router is ~ 13 meters and one reinforced concrete wall.
Tell me which router you can take.
Does it make sense to take more expensive routers, for example with AX5400? Or are they no better than the AX1800?

Answer 1

Take MIKROTIK hAP ac and that's it. anyway, you won’t get 700mb via wifi ... well, they wrote right about the wall, it will be bad through it)

Answer 2

MIKROTIK routers keep a stable connection.
If you need a maximum speed, then you can drill a hole in the wall and lay a twisted one and put a second router.
