Do you use fixed channels? Did you wait long enough for a re-connection? What caused the disconnect?

Actually i did a spectrum analysis and the connection was lost, I just checked the connection and now is up and running.So I ques reconect took longer than I was expected

Reconnects in the 5 GHz band can take a while.

Hello, I have some trouble with getting align the second pair,

as you can see in the picture first antenna, set as AP is on the top of a hill mounted on a post and the second one is at the bottom of the hill an a post too, visually there is a direct line of sight between them but I could not make the Client to connect to the AP, distance is 411 m

The hill dose not have a regular slope, it has a bulge ( that's why only the post is visible in the picture) but as I said before direct line of sight is available.

For a brief moment I succeeded in connecting the Client to the AP , I hat excellent signal strength cca -58 dbi but the connection was no good, when pinging the AP I got TTL form 1 ms to 1000 ms

What could I do to make it work?

Seeing that there's a height difference between the two points, did you account for that when setting the CPEs on the posts given that the elevation beamwidth is 30º? In other words you'd have to mount the one of the top of the hill looking somewhat downwards and the one on the bottom of it facing a little upwards..
Now serving finite customer via f(x)=AirTime/∞ on the 5Ghz band :-/

Yes, I made for them a custom mounting bracket with a joint that allows me to orientate them up or down ... but no results ... I'm thinking to use some laser to aline them

I use the information on the Status Page when aligning two CPEs. If this is not possible, I use the LEDs on the client side until I get best signal and then switch around the roles of the CPEs (client will become AP and vice versa) to do the alignment on the other side. Worked o.k. so far. Note, that two CPE510 may need some more time to connect compared to CPE201.

I'm back :) . I have resolved the last issue, I have added a 3 m extension to my pole and now that connection is working excelent. I need your help for the firs pair , distance 1,6 km, again height diference about 80 m, alignment done by the book but ... signnal quality is horible, it fluctuates from 50% to 60 and some times to 90, signal 69 - 70 dbm, ping time is very high. I have done a signal survey and I have chosen the best chanal. My network is in a rular area without many wierelles interference. I wonder is possible that the second pair to interfere with the first one, although they are on difrent chanels? or the distance of just 1,6 km is too much? Any ideas wil be much apreciated

1.6km is not much at all. I can think of several CPE setups over 3km in heavy rural areas (somewhat congested 5GHz band) with no such issues (signal quality, ping times etc). Perhaps a cabling issue (max distance ~50m from the PoE / quality / earthing / connectors) is the culprit?

Yes. Could be caused by another AP or a weather radar operating in the 5 GHz band (depending on where you live) or anything else. Blue means "peak", red is "current" and yellow (actually sand-brown) means "average" level of signals/noise. But it's not my YT video, I'm just a user of TP-Link gear.

This is a snapshot of a spectrum analysis I just did on my CPE510. Best frequencies (see arrows) would be around 5.480, 5.520, 5.600, 5.640, 5.680 and probably 5.560 GHz. But 5.480 GHz (channel 99, red arrow) isn't allowed in my country for WiFi, so I have five channels with very low noise, namely channels 104, 112, 120, 128 and 136, where on channels 116 to 132 radar could appear then and when, so I would avoid those channels if possible.







Sure. This is called Point-to-Multipoint (PtMP) mode. The CPE510 also offers MAXtream, a time-multiplex technique to ensure that every CPE client get's an equal amount of AirTime, thus minimizing interferences of the CPEs on the same channel (you can't use different channels if all clients are connecting to the same AP).

But you should pay attention to the antenna's beam width of the CPE, which is 45° on the H plane and 30° on the E plane. Therefore, if you want to distribute a WiFi signal in a wider range, you should consider use of the WBS510 with a sector antenna such as the TL-ANT5819MS, which offers 120° antenna beam width. See picture below for a typical PtMP setup using 3 CPEs and a WBS with sector antenna. The WBS510 runs under the same operating system as the CPE510 does.





Thanks for information, great answer
