Try as I might, I just can't seem to get decent performance out of my home network. It's a 802.11n network, theoretically 300 mbit/s, however testing with iperf between a Linux wireless laptop and a wired linux server results in 60-70 mbits reported in either direction.
Are you using 5 GHz? You probably won’t get 300 Mbit/s out of 2.4 GHz. (Wider channel widths mean you are far more vulnerable to interference.) Also keep in mind wireless speeds are measured half-duplex, so you only get at most half of what they say. I’ve never got more than 25 Mbit/s on 802.11g. I have a 5 GHz 802.11n AP (a HP MSM422 if you must know), my MacBook Air that says its TX rate is 270 Mbit/s. Running iperf, I get no more than 150 Mbit/s. (The laptop’s RX is far worse because I set the AP’s multicast TX rate ridiculously high to cope with multicast HDTV.) I live in a country area in the sticks. Using a Ubiquti NanoStation M5 as a spectrum analyser, I see no other 5 GHz activity whatsoever. I suspect you may be suffering from interference, which is possible in both the 2.4 GHz and 5 GHz bands from consumer devices. Also do you have devices connected to the AP that only support 20 MHz channel widths? Just a stab in the dark, but that may be bogging down the 40 MHz transmissions. -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlAzSfkACgkQvs6Qqs8TxBoPOwCfYlkHIOAa326quhetFvFAJtix EyEAn3i8mrX1Qr+54YfAz9cW8YB+zuc3 =fZGx -----END PGP SIGNATURE-----
