You are a real mess
Client has channel 1 AP has 11
Client has MaxTream off AP has it enable
You lied when you posted this on #1
When I made the first configuration in my house everything worked
That is a big lie, or you are blind
When you pair a Client, Client takes the channel from AP by default
You can't pair Client with MaxTream off and on the AP MaxTream on
That's the reason I post, you lie
I assume you have the urgency to deploy your CPEs, and your adrenaline is high
with your new toys, and you aré making big mistakes that take on the fail road
My advise
Back to the lab again
Start from scratch
factory defaults both of them
Start with AP following the Tp-Link how tos

Hi,

@danymarc, sorry about the error with the configuration with MaxTream (the channels are correct by the way), at the time I took the print screens I was trying with every option and close to trow the antennas in to the trash can, now started everything from scratch again in my house and the antennas got paired almost instantly but again when I place the client at the final location everything failed miserably again. but this time I was able to see the client getting paired and receiving data with very bad quality for less than a minute and then nothing again.

Now I'm more convinced that the SNR is the critical parameter for me, during the test in my house I placed the client at different orientations even looking at the ground, the SNR was arround to 25 and the connection was successful.

I'm seriously thinking in to buy another CPE220 to get the gain boost necessary to rise the SNR. What do you think?

Regards.

The problem could be the 6 Kms. you bought
210 5 Kms tops
220 13 Kms tops
And your link is 6 Kms. so you have one device on the link that is not capable for the distance,
in real life subtract 20 or 30% from specifications
Either you buy a second 220, or move from the 2.4 frequency,
you are going to have all the issues you can name on 6 Kms on that frequency
2.4 is very crowded, but you have half of the gear, so carry on from there

Try with 220 as ap instead client
