Thats too bad. In my throughput testing on a Planex MZK-W04nu running openwrt trunk, I can easily max out its 100mbit ethernet switch (hint, enable extra HT flags in hostapd.conf). Since the ath9k driver achieved this level of performance, I've been looking for a new unit with an atheros 3x3 radio + gigabit ethernet. The TP-Link unit is the only one I'm aware of at this time. Certainly the only sub-$100 one.
