Subject: [ath9k-devel] TX packets dropped
Date: Sat, 20 Nov 2010 23:08:29 -0800 [thread overview]
Message-ID: <4CE8C56D.6080609@gmail.com> (raw)
I have an AR9220 mini PCI card (Sparklan WMIA-198n) on an Alix 3d2 board
running OpenWrt (2.6.32.25 kernel). 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?
