Linksys WRT3200ACM and 3 radio interfaces?

Hi All,

i am trying to understand new router i bought. It is Linksys WRT3200ACM. First thing i did was to flash OpenWRT so really do not know if it was the case in original software but on OpenWRT 19.07.04 i have 3 radios like in screen shot. I thought that router has only two the 2.4 and 5 GHZ. Here are my observations:

radio 0 - 5GHz - is the fastest (around 50MB/s while copying files on LAN)
radio 1 - 2.4GHz - is the slowest (around 5MB/s copying files via LAN)
radio 2 - 5GHz - is sort of medium speed (around 16MB/s while copying files on LAN)

Can anyone explain to me why my router has two 5GHz radios?

Thanks for any clues...

third radio


Just disable the third acbgn radio.
No antenna. Not meant for regular use.


Thanks guys. Appreciate.
