 Hi,
 I installed master branch openwrt onto Asus MAP-AC2200 AP. It has tri
band. Its based on IPQ4019 DK04 QCA reference platform. 2 radios
(2Ghz/5Ghz) on AHB bus and one 5GHZ on PCIe bus. Its generally working
fine except one problem in 5Ghz. On both the 5Ghz radios the RSSI is
pretty low on any channel I put it in.  In one feet range I see -60dB
RSSI, where as the stock firmware that came with the AP gives an RSSI
of -36dB at one foot distance.The downstream transmit rates are MCS8/9
for most part. The 2Ghz is working fine. Its using the cal data from
the flash that came with the AP.

 Can you please suggest anyway to debug this or improve the RSSI?

 Thanks you!
