    Bring up terminal and ping a host, eg. if in uk, maybe type ping google.co.uk

     

    let it run for say 20 lines then press ctrl-c, it'll give you a summary.

     

    The eg. from tpkirkpatrick is a good result.  all pretty consistent.  As an fyi, ping is dependant upon internet connection, wireless etc.  At my house, I get pretty consistent under 20ms responses from google.co.uk.  The air does this but interpolates them with +100ms responses as well, up to 2 seconds....

    Here is another example.  I have an i5/8gb that I ordered the first week they were available in June.  Got it a week later.  One year old ISP provided g band DSL router.

    I've also noticed something interesting on the activity monitor network tab while downloading files.  It hits 800KB/sec received for a couple of seconds and then drops to 100-150KB/sec for the remaining of the download.  It happened both with an update from the App Store and an app download from Adobe directly.  My standard internet connection is 6Mb/sec tested on my Windows laptop and iPad2.  Then I checked from my new MB Air and it was .32Mb/s with 318ms latency.

    try the ping test on the windows laptop, then you'll get a comparison which should make more sense.  The above looks really erratic, but it depends on what you should normally be expecting in your environment.

    can you explain how to do the ping test?.

    instead of Terminal, just search in Spotlight: Network Utility (it's in the utility folder) and click on Ping

  • lunaticitizen Level 1 Level 1 (0 points)

    That was a really good result, dogschool. You must live pretty close to a Google data center You can't expect a better result that that. Now if only your MBA could maintain a stable connection...

  • andyman2 Level 1 Level 1 (0 points)

    What internet connection is that dogschool and is this wireless now wired...!?  Seems incredibly quick.

  • dogschool Level 1 Level 1 (0 points)

    No, its Centurylink wireless thrugh a Zyxel router-I guess Apple can`t blame my ISP`s speed

  • dogschool Level 1 Level 1 (0 points)

    central N.C.

  • dogschool Level 1 Level 1 (0 points)

    110 miles to the Google data center in Lenoir NC

  • andyman2 Level 1 Level 1 (0 points)

    so is that from your macbook air?  seems a very good connection.  I'm guessing you havent had connection/voip issues...?

  • dogschool Level 1 Level 1 (0 points)

    No-everything but this macbrick air works like its supposed to here...still no fix or admitting there is a problem from apple

  • andyman2 Level 1 Level 1 (0 points)

    And the result above is from the macbook air? Seems like a brilliant connection from that result only.

  • dogschool Level 1 Level 1 (0 points)

    Right...= hardware issue

  • andyman2 Level 1 Level 1 (0 points)

    would expect it to show up in your network response times though.  But they seem excellent.

     

    Not sure what your reply means above.
