Hello, I am working on an AP design that uses a TI-OMAP3 host processor with an Atheros AR9170 + AR9101 WLAN chipset. We are currently using carl9170 version 1.9.2 and carl9170 firmware version 1.9.4. During network tests, several of the clients drop-off the network. The packet captures show that the beacons sent by the AP are at a much lower power than the other data packets. For example, the beacons are typically at -75 dbm while the data packets are at -54 dbm or better. The power for all packets ranges from -99dBm to -45dbm at a sniffer (Omnipeek) sitting about 4 ft away. One theory is that the clients are missing enough beacons that they assume that they are disconnected. Is this wide variation in the AP's transmit power the expected behavior with this driver/firmware/chipset? If not, where do I look to fix this.
