Random Dropouts keep happening on my Netgear C7000. Has this been fixed yet? Looks like this problem has been happening for quite some time now. Did Netgear finally release a fix for this?  For an expensive modem/router, we expect so much more from this.

Comcast has been on this for the last several weeks/months and can't find anything.  However, their smallest test time is 5 minutes increments.  But I may have stumbled on the issues.  These statistics are for direct connect cable - computer to Router.

This site tests more than just upload and download speed.  i tests for Latency/Ping

 

We use MagicJack.  When we connect to a call, we loose the incoming voice for anywhere from 6 to 30 seconds.  We just keep talking, though that is hard to do when it is an answering machine or robo menu.  The tests explain what is happening.  But I don't know where to go with this.  Can't get to the right people at Comcast or Netgear.

 

When I ran this test the numbers in the beginning of the test were all over.  It looked like an EKG and then it is steady.  Something is happening at the beginning of the connection not only on the phone, but also when we go to other websites.

    is "UPnP" turned ON for both MagicJack and the Router? 

    Do MagicJack's settings allow selecting Incoming Ports?  More than one?

    These serttings will affect the performance of MagicJack, as well as other programs (Skype, etc.).

     Skype's "Tools" include these types of settings.  See "Tools/Options/Advanced/Connections".

      We were told to turn UPnP off for security reasons by NETGEAR.  We have forwarded them manually, all of which are UDP. See below.

       

      XXX = the dedicated ip address of Magic Jack
