First of all I would like to say that I am a newbie into this.
Can someone please explain how can I connect 2 PS5's?
Is it going to be the first as 'Access Point WDS' and the second as 'Power Station WDS'?
I have 10KM distance the one from the other but I cant get them connected. No light on antenas or signal strength.
Are they too sensitive with directions?
Please help.
Do you have a clear line of sight with *nothing* in the way?

Straight line with some tries I believe. I am not sure if there is an obstacle in the way. I have put the output power and distance to max but still nothing.
Also I would like to state that I did not change the firmware.
5.8 GHz is very allergic to trees. If you can't make the tress disappear, you'll have to go higher on your radios to clear them.

Not sure what you mean by not changing the firmware. Does that mean you did not upgrade the firmware or you did not change one of the radios to an access point.
One has to be an AP or AP-WDS and the other a Station or Station-WDS.

I did not upgrade the firmware.
You mean I have to place the dishes higher? or is there any setting I have to make?

I sugggest that for all Point to Point links that you program your radios before hand, making sure they link up and ping through to the station via AP Ethernet cable before deploying. That way you don't have to worry about configuration errors when the radios are less accessible.
If you have a spotting scope you might want to use it to determine if you can see your intended destination.
I mean....set the radios up in your shop to fully replicate what they will do on the towers/masts.
If you don't have a clear line of sight, you'll need higher masts, most likely.

Yup, do whatever you need to do to achieve a Line of Sight. 5Ghz going one mile through even one tree can be very bad for signal, let alone 10 miles.
Its on my punch list to get a comparative study and chart out trees losses at 2.4 and 5.8 GHz. The only study I know of was for 10 GHz done by either the University of Texas or Texas A&M, I don't recall off the top of my head.
There are some estimates in dB loss per tree, but nothing you can really use in the real world.

As long as google earth is concern and radioWorks I have a line of sight between the two points.
I will try to increase the height of the AP WDS higher and see.

Last I checked Google Earth did not show trees nor hills that accurately. A visual confirmation is still highly recommended before making plans on what to do about it.

I have increase the height of the AP WDS around 4 meters high and I saw one orange light on the Antena. I will try to increase the high some more today and see how it will go.
If I increase the frequency it will help? Now I use channel 36 5180Mhz.
Do I have to use security for testing to work? I have try WPA with custom number key.
You don't need any security for testing, in fact you don't want it as it ads more variables and make it difficult to troubleshoot why it don't work.
Channel 36 5180Mhz is OK for testing, but not allowed for outdoor use in most countries.

I'm gonna post a picture to show how bad a single small tree can be.

Finaly it work.
I have rase a bit more my AP and got it work with 36Mbit down and 6Mbit up. I have notice with WDS off I get some more performance on the connection. From the 4 signal leds on the dish I see 2 lighted.
Thank you all for your help.
WHT: please post the picture.

Thats bad. Even with a small tree.
What are the options to solve this matter? I suppose going higher is the one but what other options are there?
With higher frequency Stations? I hear there is a plan for 10Ghz.
What about Airmax versions?

higher frequencies give you MORE loss from trees and other obstructions.

What about the new products from Ubiquiti? Like M series etc
10 Gig is blocked by rain and butterfly farts. Satellite TV drops out in a heavy rain.
AirMax is more robust, but not the magic bullet to solve really poor marginal LOS shots.

As I said I have 2 lights out of 4 that lights on my connection.
Will this be a problem in the near future?
If I upgrade my factory firmware to something latest will this imporve the contactivity?
What I am thinking of is, if there is a way other than from rasing more the aerials to improve the contactivity.
Thanks for helping,

That really doesn't mean anything. Look at the actual "printed" signal levels because the LED indicators depend on the settings you select form the GUI.

The ultimate answer is this:
There is no substitute for adequate line of sight. Period.
You cannot put different firmware on a radio and expect the radio waves that come out of it to go through trees better. It is physics that is causing low signal on your link.
You can try it out the way it is for as long as you like, but if it starts to fade out of fail in any way the only thing you can do is achieve better line of sight.

Now I use channel 36 5180Mhz.
I thought that PS5 antennas were not wide band as the datasheet says 5400 - 5875.
I tried a 15.74 km link in 5.2 with a ps5 and it wouldn't link... once I switched up to 5.725 or higher the link worked just fine.
and 5.2 in this area is as clean as it comes.
