Hi,
Under Windows, you can achieve 10-15MiB/s..
Under Linux, even with 150mbps USB wireless adapters, the max never
appears to go above > 3-4MiB/s, to work around this, order more
USB-wifi ticks and run them in parallel far away from each other with USB
extenders:
box1:
-------------
wlan0 IEEE 802.11bg ESSID:"hidden"
Bit Rate=54 Mb/s Tx-Power=20 dBm
wlan1 IEEE 802.11bgn ESSID:"hidden"
Bit Rate=58.5 Mb/s Tx-Power=20 dBm
wlan2 IEEE 802.11bgn ESSID:"hidden"
Bit Rate=39 Mb/s Tx-Power=20 dBm
box2:
-------------
wlan0 IEEE 802.11bgn ESSID:"hidden"
Bit Rate=58.5 Mb/s Tx-Power=20 dBm
wlan1 IEEE 802.11bgn ESSID:"hidden"
Bit Rate=52 Mb/s Tx-Power=20 dBm
wlan2 IEEE 802.11bgn ESSID:"hidden"
Bit Rate=52 Mb/s Tx-Power=20 dBm
But I was curious if anyone had achieved > 10 MiB/s with any wireless
adapter with Linux?
Also, those native Linux USB adapters (carl) work good, so far.
With the patch provided earlier for the rt2800usb driver, it is no longer
crashing under 3.0 so I put two of them on a single box plus a carl based
one, now I get better I/O, e.g. 4MiB/s x 6 = 24MiB/s.
Justin.

On a 150 Mbps connection running the following script
#!/bin/sh
dest="sonylap" # set the servername
while true ; do
netperf -t TCP_MAERTS -H $dest
netperf -t TCP_STREAM -H $dest
netperf -t TCP_SENDFILE -H $dest
done
I get the following for a D-Link DWA-130 containing a Realtek RTL8192SU with
driver r8712u:

I claim that 50-65 Mbps is pretty good.
We get better than 10 Mbps with lots of different adapters.

This means about half of fast ethernet (5-6,5 MB/s). It's too
insufficient for 802.11n / 40 MHz.

-> there is room for optimization! I don't think, that the rt3572sta is
the best solution absolutely seen :-). Unfortunately, I don't have a
windows machine to compare ... . Maybe, I could get one to test ... .

Well, if your AP which you are connected from Windows host
has linux based firmware (what is most probable), then linux
is capable to transfer also at 10-15 MiB/s :-)
But yes, I never achieved more than 10MB/s on linux station.
Best results I have is about 7.5MB/s on 2.4 GHz networks and
10MB/s on 5GHz .
