I have the Archer C7 v5
for wireless (2.4 GHz and 5 Ghz), I am trying to figure out the settings for TX Antenna Chains & RX Antenna Chains. The software defaulted to 1+2+3 (the same setting on both). I was reading this https://wiki.dd-wrt.com/wiki/index.php/Atheros/ath_wireless_settings#QCA_Q-Boost_.2F_TDMA__support
(under the section "TX & RX Antenna Chains") which says that in general the defaults are relatively accurate. It also suggested that I can use the FCC ID to help figure out what to use. But, when I go to https://www.fcc.gov/oet/ea/fccid FCC ID TE7C7V5 shows 3 “listings” with an upper and lower frequency for each but I don’t see any other useful information (not that I know at all what I am looking for).

The device is a 3x3:3

Ok, thanks. I am going to go with the 1+2+3 setting for both. I hope it works ok.
