I set up the radio in AP mode, give it encryption, then connected with another computer with an Intel 802.11n card. The connection wasn't reliable, so I tested it with iperf. When the client sends packets, they almost all make it, but when the AP sends them, no more than 66% make it. I'm trying to figure out what the problem could be. It shouldn't be interference--this is in a 5ghz band, and RX was fine. It could be a bad pigtail or antenna, but I'm not sure how I can test for that. It might be the motherboard's power supply, so I'm looking into how many watts it can supply (the card specs say it takes ~2.5 watts). I tried forcing 802.11g mode, and the issue was still there, and I dropped TX power, but it didn't seem to affect anything. Any ideas? Is there a way to check stats on each antenna?
