RT-N66U issue: devices connected in LAN don't meet

[NASIOPAMATA]

Hi everybody from Spain.

I have a RT-N66U. I use the 5 GHz wifi only for my computer and one TV. Because of the distance (and walls) between the router and the living room tv, or the others tv's/devices, I bought the TP-Link AV200 and another TL-WPA2220. These devices have both Rj45 and wifi.

In my room, I have one TL-WPA2220. Connected to it are my Galaxy S3 and my mini PC MK808B (finally arrived to the issue). The MK has an app for installing in a phone, tablet,... the RkRemoteControl. Is for handling the MK808B with the cell phone. The S3 and the MK808B MUST be connected to the same network and they're connected via wifi to the TP-Link and from it to the router via PLC. The issue is the S3 and the MK don't meet though the router can see all of them.

I have installed the Merlin RT-N66U_3.0.0.4_374.43_0 firmware.

Does anybody know why MK and S3 don't meet each other??? This is important for me because I have a disability and I don't have any other way to handle the MK808B.

Thank you very much.

Regards.

...my guess is that at least one of your wireless APs is operating in safe/isolation mode.
This will prevent wireless clients to communicate with each other over the WiFi.
Check all configs and disable it.

Ok, I'll try this.

One more question; sometimes, when switch on the MK only for a few seconds meets the S3 and I can link them. After that, they rest linked by hours but only if the RkRemoteControl app is running everytime. If somebody calls me or use Whatsup (or any other app) the link is broken and is impossible meet them again.

Maybe the same issue you guess???

Thank you a lot.
