Asymmetric wireless speed

    Hi,
    I have a small problem with my wireless on my laptop. When I receive, I can sustain a connexion of about 20mbps, which is ok. However, when I send, I can barely hit 10mbps (more like 7-8). Any idea why?

    Do you get symmetric rates over ethernet? How did you measure your wireless rates?

    Ethernet is not a problem. For measurements, I use iperf (under linux).

    Wireless is half duplex.

    That is true, however I don't see why my router can sustain higher bandwidth than my wireless client. And we're talking about a big difference (20Mbps vs 8Mbps).

    its possibly the router is transmitting at a higher power than your wireless card, so it results in a better signal quality from the client's viewpoint (and higher bitrate), and lower at the router's viewpoint (lower bitrate)
