Wifi Issues?

I continue to be blown away by the things that I can now do with a super fast Internet connection.

Last night it was catchup TV where I was able to download and start watching a show in HD within seconds of making the request.  Two months ago I would have had to plan days in advance to watch catch up in HD!

I know that my experience is being shared by other residents but there are some people that have had, or are having, issues with wifi coverage and/or signal strength since upgrading.  The following is a summary of advice that might help if you are experiencing issues.

  1. Make sure that the Technicolor router is located in the best possible position per this topic on the Call Flow website.  Ideally this would be connected to your master socket and the positioned somewhere higher rather than lower. Mounting the router on a wall can be a good option but you may need to experiment with different locations to find the best one for your property.   If you have a phone socket that is more centrally located within your property then try that socket and see if it provides better wifi coverage while still having a good connection for the router.   You may need to compromise between the best possible speed from the router to the internet versus the speed within your house via the wifi network.
  2. It might also be helpful for you to follow this advice on how to "tune" your router to a better channel.
  3. There is a wide range of relatively inexpensive options that help you extend your wireless network.  These include products called range extenders that rebroadcast the wireless signal as well as products that use your ring main (power lines everywhere else in the world) as a hardwired connection between the Technicolor router and a remote access point (or wireless antenna).  In the former case we have seen at least one user that lost overall performance implementing such a strategy due to interference with the wifi signal.  In the latter case the performance of a powerline adapter solution will depend on the condition of your wiring.  I have not yet seen a case where I was impressed by the performance of a powerline solution.  If someone does get either of the two options above working well I would love to be able to update this entry!
  4. Lastly are the not-so-inexpensive solutions.  There is technology called a "whole home wifi network" or sometimes a "mesh network".  This type of network is implemented by using two or more devices that work closely with each other to create a network that can cover an entire house regardless of its size (only limited by your budget for each device that you need to place throughout your home).  One resident, that would be me, purchased BT's solution (around 200 quid) and is only needing two of the three devices that came with the starter kit.  One is in the guest bedroom at the front of the house where the master socket is located.  The second is under the bed in the master bedroom.  We get 115mbps at the router and no less than 100mbps everywhere else in the house including my office which is an addition off the lounge.

One thing that bears remembering if you have an issue now and wonder why you did not with your old service.  Remember how fast that old service was?  It is really easy to move 1-3mbps of data around a network!  It is a lot harder to pump nearly 100mbps around!
