    I am having wifi through put issues on my new mid-2011 iMac.

    Connects to the network fine, but through put is low, when compared to a Mac Pro (5+ years old) sitting beside it on the same wifi network.

    I think there might even be errors, as Parallels with XP on it can not load the configuration page for my ethernet switch, and once again the same VM on the Mac Pro works fine on it's WiFi.

    Still diagnosing where issue may be, but is anyone else noticing issues?

    Perhaps.

    I don't want to jump full in and say ME TOO! quite yet but I too seem to be experiancing slow Wi-Fi connections speeds on my new Mid 2011 iMac as compared to my 2009 iMac. It's just I have not done enough troubleshooting to be POSITIVE its not my problem, but I never had these issues with my other iMac.

    I had the same issues with my iMac, in the end I decided to manually assign IPs to every device and it fixed the issues.

    thanks tried that, did not help.

    I AM having an issue.

    I have 2 Wifi networks in the house.

    1 - Airport based thus 'n' cossaboon.net
    2 - Non - 'n' a/b/g 2011.cossaboon.net

    When connecting to the 'n' network I can ping devices in the house, no dropped packets. When I move to the 'g' network, I drop packets, AND it shows as 'n' on the iMac. Based on the channel and frequency, I think it is a not N.....

    On GigE / ethernet

    Code:
    11 packets transmitted, 11 packets received, 0.0% packet loss
    round-trip min/avg/max/stddev = 0.896/1.438/6.198/1.506 ms
    
    On 2011.cossaboon.net

    Code:
    15 packets transmitted, 12 packets received, 20.0% packet loss
    round-trip min/avg/max/stddev = 1.547/94.187/301.253/103.372 ms
    
    on cossaboon.net

    Code:
    12 packets transmitted, 12 packets received, 0.0% packet loss
    round-trip min/avg/max/stddev = 1.747/3.929/12.672/3.554 ms

    Kinda fixed

    Called Apple
    Boot from System install DVD
    repair permissions
    boot onto HD

    Now it joins the 2011.cossaboon.net network at 2.4ghz not 5ghz, and no dropping packets.

    I could still have a 'a' network issue, but I am rolling....
