Temporary fixes to Sky Muster internet connection problems July 2016

Problems include

  1. Unable to visit certain websites, especially HTTPS ones.
  2. Unable to do any form of remote logins (Reckon, Phoenix, Microsoft Remote login etc)
  3. Short term dropouts, especially noticeable in any forms of chat.

Possible solutions that have worked for SOME people (see below for more details)

  1. Clear the browser cache.
  2. Turn off iPV 6 on your computer and/or router (Note SkyMesh has done this for their Sky Muster service so no action is required for SkyMesh customers)
  3. Ask your provider to turn Web Acceleration OFF
  4. Test using a VPN application called Tunnel Bear
  5. Enable TCP Timestamps
  1. Clear the browser cache.

    See here for instructions http://www.refreshyourcache.com/en/home/

  2. Turn off iPV6 on your computer and/or router

    Instructions here for Mac OS X https://kb.iu.edu/d/aqig
    Instructions here for Windows https://support.microsoft.com/en-au/kb/929852
    Y    ou will need to read your router’s manual to determine how to turn off iPV6 in it.

  3. Ask you service provider to put a request into NBN to have web acceleration turned OFF
    for your connection.Browsing will be slower, but you should be able to visit the problem websites.
    Ask Service Provider to get NBN to disable the Transparent Performance Enhancing Proxy (TPEP)
    Web Page Optimisation to OFF, Transport Protocol to OFF
  4. Trial a VPN application called Tunnel Bear (first 500Mb is free)https://www.tunnelbear.com/
    Download the Tunnel Bear extension in Google Chrome
    Visit the website via Chrome with the tunnel bear extension turned on
    If your secure website or Remote desktop is now working, let your Service Provider’s Support know.
  5. Enable TCP Timestamps (this has now been done at the NBN end of SkyMuster, so you shouldn’t have to do this)The following was worked out by technical support at SkyMesh. Original Workaround provided by SkyMesh  here

Detailed below is a temporary workaround for customers with Sky Muster services that are having issues browsing some websites. Some operating systems do not have the TCP Timestamps extension enabled by default. By enabling this extension on each affected computer, customers can overcome the problem. The workaround temporarily resolves a certain class of issues. If you continue to experience browsing issues after enabling timestamps, you might be affected by a different problem.

You must run the command prompt as the Administrator.
