Why is my Wi-Fi rubbish ?

When you have a wired connection it is just your computer connecting to the network via that 100Mbs or 1000Mbs (1Gbs) cable. Once you connect via Wi-Fi other factors come in to play.

What speed does the Wi-Fi access point support? In 2016 the basic router comes with a 150Mbs Wi-Fi capability, but with better units it can increase to 1750 Mbs.

  • Wi-Fi speed drops off with distance
  • Wi-Fi is a shared connection so 10 devices each connecting to the same 150Mbs each get 15Mbs
  • As with Internet connection speeds, for various technical reasons you never get the headline speed,

So the 150Mbs is often 72Mbs or less, shared among the devices means a busy Wi-Fi access point is often delivering less to each connected device than the onward Internet connection will support.

There are two main frequencies for Wi-Fi and you will find that most people are using the common 2.4GHz, so that other peoples Wi-Fi, in other organisations / rooms / buildings with produce a “fog” of background Wi-Fi noise which will help mask your signal and slow your connection further.


What can be done to give me the best signal possible?

  1. Cable more Wi-Fi access points, but poorly placed or configured can make things worse
  2. Use Wi-Fi access points that support higher speeds
  3. Use Wi-FI access points that support both 2.4 Ghz & 5 Ghz frequency
  4. Select channel bands that aren’t being used by others in your area
  5. Use a Wi-Fi controller to balance the load among your Wi-Fi access points
  6. Place the points to give optimum coverage

Obviously we at CTi Communications Ltd, can help with all or any part of providing you with full high speed Wi-Fi coverage.
