Below is the out put from iperf on windows (about 3x faster). Not sure what to do to get better throughput...is this considered a bug or a lacking feature ? It looks like its maxing out at 54MB/s on a 5Ghz AP, makes me wonder if its using 802.11a, in lieu of 802.11n ? ------------------------------------------------------------------------------- ------------------------------------------------------------ Client connecting to 192.168.10.52, TCP port 5001 TCP window size: 63.0 KByte (default) ------------------------------------------------------------ [148] local 192.168.10.60 port 50087 connected with 192.168.10.52 port 5001 [ ID] Interval Transfer Bandwidth [148] 0.0-10.0 sec 76.0 MBytes 63.7 Mbits/sec (Windows 7) ------------------------------------------------------------------------------- ------------------------------------------------------------ Client connecting to 192.168.10.52, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.10.60 port 42587 connected with 192.168.10.52 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 25.5 MBytes 21.3 Mbits/sec (Ubuntu) ------------------------------------------------------------------------------- sakhter@sakhter-laptop:~$ iw dev wlan2 link Connected to 30:46:9a:10:49:f7 (on wlan2) SSID: sakhter-5g freq: 5200 RX: 222040 bytes (949 packets) TX: 12082 bytes (77 packets) signal: -45 dBm tx bitrate: 54.0 MBit/s > On Fri, Oct 1, 2010 at 10:36 AM, Christian Lamparter > <chunkeey@xxxxxxxxxxxxxx> wrote: >> >> On Friday 01 October 2010 16:22:45 Saqeb Akhter wrote: >> > Hey Guys, >> > >> > I just got around to compiling compat-wireless on ubuntu 10.04, to >> > make use of the new carl9170 driver which is supposed to be able to >> > handle 802.11n. >> > >> > My router is a wndr3700 running @ 5ghz on windows I'm able to get >> > pretty good speeds.
