Also: read back in the thread. One of the 5G radios is only for lower frequencies and the other radio is for higher 5G frequencies, don't use them wrongly or they will not be very efficient.
Am having a weird issue with my R8000, I suddenly have extremely slow speed even in Stock OS.
In OpenWRT / LEDE, 5G radios are not turning on. I have done the required NVRAM Reset and all and now in Stock am getting around 18MB/s in 5G where as i used to get around 55+ MB/s.
Would provide the log if needed. Do you think i need to change any values in NVRAM or is there something wrong in Board_Data mtd partition that this problem continues across firmwares ?
PS:- This happened after i flashed tomato to test it out, and when i came back to LEDE my 5G Radio just won't get enabled !
