    Do you guys have a ping issue and possibly a throughput issue?

    I have a Haswell iMac and Macbook pro and both machines exhibit really high pings over wifi.

    Open a terminal and try... e.g. :

    press: cmd + spacebar
    type: terminal
    press: enter key
    type: ping

    my typical output from my adsl connection

    PING ( 56 data bytes
    64 bytes from icmp_seq=0 ttl=58 time=30.052 ms
    64 bytes from icmp_seq=1 ttl=58 time=133.302 ms
    64 bytes from icmp_seq=2 ttl=58 time=43.235 ms
    64 bytes from icmp_seq=3 ttl=58 time=65.324 ms
    64 bytes from icmp_seq=4 ttl=58 time=89.182 ms
    64 bytes from icmp_seq=5 ttl=58 time=112.213 ms
    64 bytes from icmp_seq=6 ttl=58 time=32.163 ms
    64 bytes from icmp_seq=7 ttl=58 time=54.748 ms
    64 bytes from icmp_seq=8 ttl=58 time=77.396 ms
    64 bytes from icmp_seq=9 ttl=58 time=101.273 ms
    64 bytes from icmp_seq=10 ttl=58 time=123.731 ms
    c64 bytes from icmp_seq=11 ttl=58 time=44.756 ms
    64 bytes from icmp_seq=12 ttl=58 time=66.446 ms
    64 bytes from icmp_seq=13 ttl=58 time=90.136 ms
    64 bytes from icmp_seq=14 ttl=58 time=112.819 ms
    This is disappointing. I suspected wifi interference because i ping my routers ip it is the same high pings ruling out my ISP. So if it's local maybe my wifi is the problem. Tried all channels.

    Switching to ethernet solved the issue, but i also have windows 8 on this iMac and i tested wifi ping and it is a solid 29ms - 31ms regardless of how long i run it for. So now it points back to a mavericks issue. If it is a mavericks issue, more people should see the problem.

    My Macbook Pro 13" is exactly the same. So i don't think it is a hardware problem (2 different machines have the problem, but ok in windows).

    Someone suggested this might be a power saving feature but my throughput is behaving erratically too.

    I wrote an app to fix this.

    I had the same issue, went to an Apple retail store to get the wifi card replaced, and that didn't fix it!

    So, I wrote an app to fix it using solutions / workarounds posted in various forums.

    Hope you like it!

    I once did a university project and I realising pinging from Mac Os X (Was doing my project on Mountain Lion than) was way slower compare to pinging on Windows.

    Windows will receiving a response at a lesser time(faster response) compare to Mac OS X. Not so sure why but according to my lecturer it is due to the way the OS was written.

    I guess there nothing we can do about it but raise this issue to apple engineers.

    If you are testing your wifi you should ping the first "hop" in your network. Typically home routers have a private LAN ip of, but you can figure this out by looking at the first entry of your traceroute results to yahoo, google, etc.

    Then ping the first address you see in the traceroute results. This will give you a better idea of your wifi connection.

    When I ping my local router with a wired connection I see results like:
    PING ( 56 data bytes

    64 bytes from icmp_seq=0 ttl=64 time=0.752 ms
    64 bytes from icmp_seq=1 ttl=64 time=0.665 ms
    64 bytes from icmp_seq=2 ttl=64 time=0.683 ms

    On my laptop via wireless it varies and I've seen timeouts and some round trip times > 100.00 ms.
