AP (WiFi) able to work in client mode?

Question

WiFi

Good evening!
There is a wireless network "A", with authorization by poppy addresses. It is necessary to create a wireless network "B", using a device that would connect to the network "A" as a client, after which it would create a network "B" based on itself. What device can be used to do this? Wifi repeater does not save the situation, because. in the "subsidiary" network it is impossible to make authorization by password. I would also not want to fence a garden with two devices.
Thank you.

Answer 1

Only a device with two WiFi chips or two network devices - one client, the other guess what.
A chip cannot be both a client and an AP at the same time unless it is a WDS (dumb repetition of frames).

Answer 2

Mikrotik mAP

Answer 3

You take a device with two bands (2.4 and 5GHz), connect to device A in the 2.4 band, and distribute it in the 5GHz band, it worked for me on Kinetic Ultra (well, or vice versa, connect to 5GHz, distribute to 2.4) .
