Why is my Internet so slow? Improving NBN speed


Most Australian households have several internet-enabled devices. Internet speeds are more critical than ever as more people embrace working from home. 

If you have a slow internet connection at home, you’ll need to identify the cause to help resolve the issue. Let’s discuss possible reasons why your internet is slow and how to fix the problems. 

Potential Reasons Why Your NBN is Slow

  • Network Congestion

Network bandwidth works like a regular road with traffic. An increase in the number of vehicles on the road slows down the speed, much like how many network users cause congestion.

Internet speeds are particularly slow during peak hours.In such a case, a PRTG bandwidth monitoring tool can assist you by optimizing network performance and uptime.

  • Hardware Issues

Outdated software or hardware could be the cause of your slow internet. Older modem or router models may be unable to optimise fast internet speeds.

The best solution is to upgrade to a newer version or model with better capabilities. 

  • Distance from the Node

The distance between your home and the node affects your internet speed if you’re using a fibre to the Node (FTTN) connection. The signal moves via old copper wires, and hence the signal degrades with distance. 

  • Plan Speed

Most NBN providers rarely deliver the internet speeds they advertise. There are four NBN speed tiers that range between 12Mbps and 100Mbps.

If you’re paying for a cheap plan, your connection likely is 12Mbps.

  • Connection Issues

NBN is an extensive network with numerous potential problem areas. Issues can arise within the network and affect the internet speed. 

Most NBN connection issues are primarily due to faulty equipment and network delays.

Ways to Fix a Slow NBN Speed

  • Run a Speed Test to Help Troubleshoot the Issue

If you have a high-speed plan but struggle with a slow connection, an internet speed test can help you identify the issue.

You can get free internet speed tests showing exact upload and download speeds. If your speed is slow, the issue is likely on your provider’s end.

  • Update or Upgrade Your Modem

An outdated modem or router will likely support slower internet speeds. Upgrading to a newer model or updating the software can have surprising results on your internet speed. 

  • Try Mobile Broadband or Home Wireless Broadband.

If your NBN connection is unsatisfactory, you should consider switching to home wireless or mobile broadband. Both function using the same network as your mobile.

If your mobile network provider offers great coverage, you’ll likely have a stable home wireless or mobile broadband connection. 

  • Sign Up for a Faster Speed Tier

If your current NBN tier offers slower speeds, signing up for a higher tier will fix the issue. You can confirm your bill if you need clarification on the speed your current plan offers.

  • Change NBN Provider

The speed of your NBN connection depends on your provider. Regulations require NBN providers to disclose the expected speeds so that you can compare different plans. 

We can all agree that slow internet speeds interrupt our lives, especially when working from home. The slow pace may be due to various factors, making it challenging to identify the exact issue.

If the above suggestions fail to work, it’s time to get in touch with a recognised NBN technician for assistance.
