Subject: Linux Wireless USB-Stick Question

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.
