I have set up quite a lot of wireless links. Generally I use Atheros chipset PCI cards in Gentoo Linux machines, and if I need an access point I use the Netgear WG302 as it is a solid piece of kit and very stable. On this network: Netgear WG302, 16Dbi Waveguide Duron 1.3, Gentoo Linux, Atheros 802.11G Card, Hills 19DBi Para Duron 1.3, Gentoo Linux, Atheros 802.11G Card, Hills 19DBi Para with about a kilometer (no more) between them I was getting 20mbit real throughput with iperf, and that was inside an OpenVPN tunnel. I also built a link using PC-Engines WRAP, Mikrotic RouterOS, 2x Atheros 802.11A Cards, 2x HyperLink 17DBi Backfire PC-Engines WRAP, Mikrotic RouterOS, 2x Atheros 802.11A Cards, 2x HyperLink 17DBi Backfire And got a full duplex 20mbit through it, over around 800 meters. That is with WPA turned on and in bridge mode. John R. McPherson wrote:

I've been twiddling with my wireless router settings and nothing I've changed so far has improved performance. Some appeared to degrade it a little.
I'm still only getting 120kbytes/sec in gFTP/SSH. Which translates to about 1Mbit/sec. This is supposed to be a 54Mbit device. Come someone else with a 802.11g wireless network do a little throughput test and let me know what sort of data rate they get.
That sounds about right.
No it doesn't; my laptop connects to a wireless AP which does NAT and then through another switch to my server (yes this is dumb but I can't be bothered getting it to not do NAT); iperf (as Kyle described elsewhere in the thread) says I get 20.3Mbits/sec between my laptop and my server. If I do a wget on a ~30megabyte file from the server to the laptop, I get 2.66MB/s, which is about 21Mbits/second.
There is a wall or two between the laptop and the AP in a hallway closet about 10 metres away.
It's possible that doing NAT and/or all those PCI busses on the router, switch and server are slowing it down a bit...
