I don't know spanish at all.
So I have tried a lot of things. On client side I tried with wds on auto, disable, enable. On the AP side if I enable wds and try to connect with cpe210 it becomes completely unresponsive until I poweroff the cpe or stop trying to connect. Another thing to note that I think is not good is that if I have access list on the ap and the mac address of a cpe210 is not in that list it makes hundreds of attempts per second to connect and it disturbs the connection of all other connected stations.

Question, GrooveA-52HPn can handle both bands 2&5Ghz and are you using the new packaged antenna

I am using an Omni antenna, but not the supplied one with the device. It is set on 2Ghz band.

Do you have the supplied one to test
And the GrooveA-52HPn can se set to either band, does it have a setup to both at same time

It cannot be used at both bands at the same time. You set one or the other. The Groove is mounted and as I said there are other clients connected to it so antenna is not the issue. The cpe210 connects to the Groove with a signal around -62.
Also the other device I am testing with has only a small 1,5db antenna attached to it and they are 1m apart, signal again is good, but also not too strong to overload the receiver.

Could it be a factory mistake you have a 5Ghz unit packed on a 2.4Ghz case

There are 15 connected stations all working good. They are a mix of tplink 5210, 7210 and some other cpe's. So it is not possible it is a mistake. All those other devices work on 2,4GHz band.
And as I said the cpe210 connects and stays connected it is just that no data is passing at all. If it was the wrong band it would not connect at all, it would not even pick up the AP when scanning.

we have seen it before, some devices are not compatible, I dont see another one. never received answer from Alejandro and that one wont come, cause I saw a answer from him last night on the forum to another issue.
As I posted Tp-Link should jump into this one.

I am hoping for some answer from Tp-Link too, that is why I am writing here.
It is almost clear to me that it is some protocol compatibility issue, but I hope they can fix with some new firmware.

Let me post some logs from the mikrotik ap. Here is what happens when a Tp-Link TL-WA7210N connects :
Jun 26 12:13:41 192.168.10.47 wireless,info C4:6E:1F:4B:CD:77@wlan1: connected

And here is the log entry when the Tp-Link CPE210 connects :
Jun 23 12:14:08 192.168.10.47 wireless,info C4:E9:84:33:4F:51@wlan1: connected, wants bridge

Why does it want bridge mode when I am using wisp client mode and it should connect as station. The same way as the 7210 does. If there is an option in some "advanced wireless" menu to disable "wants brigde" then I am sure it will work.

using wisp client mode

I dont remember if you posted you had tried Client mode
