Hi @dobbor11
They will act as a mesh network, irrespective of the backhaul medium. Will the WiFi signals be the same strength - that is all down to the mesh algorithm that it uses. Most of the time, both nodes in the mesh network will use the same Wi-Fi channels on each band.
If you just had a router & extender, not in a mesh, they give out a fixed signal strength. Therefore, at certain locations in your property, there is every chance that the two WiFi signals (for example, on channel 6 in the 2.4GHz band), unless operating on different Wi-Fi channels, will interfere with each other. This is likely to reduce the speed/throughput at that point, effectively creating a new blind spot.
All nodes in a mesh network work to avoid such problems. It is important to understand that the Wi-Fi signal from the router is most likely transmitting at a higher level than a device does back to the router. If the device's output signal is lower, this can cause problems with Wi-Fi performance. The device may be able to receive a signal from the router, OK. However, it may not be able to connect to the router's Wi-Fi, as its transmit power is too low. If it does connect, it may slow down all other devices. This is because the device that is too far away is consuming a lot of airtime trying to connect or respond to the router. Therefore, it is not just the location of the router, but also that of the device that needs to be considered.
