Hello,
I've setup a little WLAN at home, using my freebsd box as an access
point:
- FreeBSD 6.2 (tag=RELENG_6_2)
- DLink DWL-G520 PCI card (Atheros chipset)
- hostapd configured with WPA
The "client" is a powerbook G4 (Built-in 54-Mbps Wi-Fi, certified for
802.11g and 802.11b interoperability) running Mac OS X 10.4.9
The powerbook is 1.5 meters away from the Dlink antena, and ath0 is
in "mode 11g" and "pureg".
The best transfer rate I can achieve is 3.1 MB/s from the powerbook
to the freebsd-box, and about 2.7 MB/s from the freebsd-box to the
powerbook.
Any idea how I could boost my transfer rates ?
thanks,
patpro
