Device access across wifi radios

[jpalo]

Hi,
I'm most definitely lacking correct terminology here, as I can't seem to think of correct search query words to find questions similar to this nor answers.

I first noticed this on my Sonos speakers (which are connected to 2.4 GHz wifi): whenever I'm connected to 5GHz wifi with a phone/computer, I cannot control the speakers, they're just not found. Tested the same with two computers connected to different radios, they cannot see each other.

Is this just a matter of some configuration? How to make all wireless devices one happy family, regardless of teh gigahertzes? Only remotely related setting was AP Isolation, which was Off for both radios.

Using RT-AC87U.

Have you disabled 5Ghz radio to check if that was the issue? Do you need the 5Ghz radio on for your computer/phone? The only thing I've noticed with 5Ghz was having more bandwidth avaiable when streaming... and that would be for 20Mbit/s+ files. 2.4Ghz will work perfectly fine for any other type of streaming.

Thanks, I'm aware of that "workaround".

Extra bandwidth of 5 GHz would be nice, but will need to fall back to 2.4 GHz if traffic doesn't flow between them. I'm still doubting my configuration, do I need to put "loopback" cable from LAN port to another or something in router for this to work?
