Move the Router Antennas up or down

[Lukass2000]

Hello,
would like to screws my asus RT-AC87U to the wall in my livingroom.
Would set the router completely up, whereby the antennas point downwards.

So my question:
Does it make a difference whether the antennas are aligned up or down?

Could that make worse my wlan range on my floor?
Thanks

Yes, because most WiFi antennas are omnidirectional. https://en.wikipedia.org/wiki/Omnidirectional_antenna

As long as the antennas are basically vertical in both cases, the radiation pattern will be nearly a "doughnut" with the best signals at right angles to the antenna axis--in other words strong in horizontal directions in your case.

I suggest to mount the router with the antennas up or down based on best network- and power cable routing.
My concern with the antennas close to the wall is the wall structure and bad effect to the signal.
If the wall is armed concrete it would not be the best to mount the router against it.

Just do a controlled test. Too close the the wall mounting can have an effect depending on what the is the material of wall. It is all case by case, no general rule.

beamforming takes care of most of these issues these days , antenna orientation used to be a thing back in the days of wireless G and N but not so much any more
