Why is my NBN slow?

“Why is my NBN slow?” Well let’s find out, following these steps you should be able to identify the problem with your NBN internet connection.

Introduction: The Connections managed by your ISP

There are 3 connections managed by your ISP, where the fault may lie when your NBN is slow.  These 3 connections are noted as Connections A, B & C in the diagram (figure 1) below. The other problem area could be your router’s WiFi (if you are using it), noted as Connection D in the diagram.

It is as simple as running 3-4 speed tests on the connections above, to be able to tell where the slowness is stemming from. Which will allow you to identify:

  • If your NBN connection is running to the ISP’s advertised speed, and you just may need to reconsider your plan; or
  • If something is wrong with Connection A, which could be router or cabling issue; or
  • If something is wrong with Connection B – an internal issue between your ISP’s interconnects; or
  • If something is wrong with Connection C – a problem with your ISP’s connection capacity to the Internet; or
  • If something is wrong with your Wifi – Connection D.

Step 1: Know what you are Paying for when it comes to the NBN

Step 2: Conduct the Speed Tests

Office essentials on the table, laptop, coffee, phone, using the NBN shouldn't be stressful

How you conduct the speed tests, depends on how you are accessing the internet:

Step 3: Compare the Results of the Speed Tests

Now that you have completed the Speed Tests of the ISP managed connections, you can compare the results to see where the slowness is stemming from.

Hope all this helps!

Snail on pavement, slow like the NBN can be.
