I have bought a linksys EA8500. Flashed OpenWrt and so far I'm happy with it.
I'm now trying to optimize the wifi coverage and trying to get more information about the radio part.
This router is dual band (2.4Ghz and 5Ghz) and the instructions manual state that have 5 antennas (4 external and 1 internal - this one must be PCB-based). Anyway, I'm trying to understand if all the antenna ports are dual-band or if some are 2.4Ghz and others 5Ghz. I read somewhere that even though the physical antenna could be multi-mode, the port it attaches must be either 2.4GHz or 5GHz. I'm not sure it would be like that.
The TOH doesn't state it and does neither the linksys documentation...
Any thoughts on this?
