so this is RX test where I assume your 7265 card is sending data. is that HT20 or HT40 mode and do you get regression on TX too? can you try same case 2 test but with registers set to: TX_SW_CFG0, 0x00000401 TX_SW_CFG1, 0x000C0000 TX_SW_CFG2, 0x00000000 (or 0x000C0408) did you ever notice any tx power difference between nexx fw and openwrt fw?
