Why is My NBN So Slow?
Experiencing Slow Internet Speed?
Have you switched from ADSL or cable to NBN only to find that your internet speed is slower than expected? You’re not alone. Many Australians struggle with NBN speed issues that leave their connections unstable and unreliable. Understanding why your NBN connection might be running slower than expected can help you find solutions to improve your internet speed and overall experience.
How NBN Infrastructure Affects Your Connection
To understand why your NBN might be slow, it’s essential to know how the NBN network operates. The NBN infrastructure in Australia is built around 121 Points of Interconnect (POIs). These are crucial points where your NBN service links to the wider internet. Internet Service Providers (ISPs) purchase bandwidth at these POIs through what’s known as a Connectivity Virtual Circuit (CVC). The amount of CVC an ISP buys directly impacts your internet speed, especially during busy times.
The Role of CVC in Internet Speed
CVC is essentially the amount of bandwidth ISPs buy to support their customers. If your ISP buys too little CVC for your area, your NBN connection can run slower during peak hours, usually between 7pm and 11pm. This is when multiple devices in homes are often used to access the internet, causing network congestion. Conversely, purchasing too much CVC can drive up costs, which may then be passed on to you.
To ensure a stable NBN connection, it’s vital that your ISP balances CVC allocation with customer demand. If your internet connection slows down significantly during peak periods, it could be due to inadequate bandwidth allocation by your provider.
Common NBN Connection Types and Their Challenges
The type of NBN connection you have significantly impacts your internet speed. Older technologies like Fibre to the Node (FTTN) still rely on outdated copper wiring, which can lead to slow speeds, especially as the distance between your home and the node increases. This type of connection is prone to signal degradation, resulting in speed issues that can make activities like streaming Netflix, downloading large files, or using multiple devices challenging.
Upgrading to Better Connection Types
If you’re currently on FTTN and experiencing slow speeds, upgrading to Fibre to the Curb (FTTC) might be a viable solution. FTTC brings fibre closer to your home, reducing the length of copper cable needed and, therefore, enhancing your broadband performance. Upgrading to a higher speed tier on your NBN plan can also provide a noticeable improvement. For those struggling with FTTN, considering other connection types like Fibre to the Premises (FTTP) could also lead to faster, more reliable home internet.
Modem and Home Wiring: Hidden Culprits of Slow Speed
Your modem plays a critical role in your internet connection. An old modem may not be capable of handling the higher speeds of newer NBN plans. Additionally, how your home is wired can significantly impact your internet speed. Issues such as bridge taps, faulty sockets, and outdated lead-in cables can degrade your connection quality.
Upgrading Your Modem for Better Performance
If you suspect that your modem is causing slow internet, consider upgrading to a model compatible with your NBN plan and capable of handling faster speeds. A modern modem can reduce network congestion within your home, improve WiFi performance, and better manage multiple connected devices. Remember that modem make and compatibility play a big role in ensuring your internet runs efficiently.
Fixing Home Wiring Issues
Home wiring problems often contribute to slow speeds. A professional inspection can identify issues such as damaged cables or incorrect wiring setups. Replacing old wiring, removing unnecessary bridge taps, and ensuring proper installation of your NBN connection can help achieve higher speeds. For those using older copper cables, an upgrade to modern, insulated cables can prevent interference and improve signal strength.
Network Congestion During Peak Times
A common complaint among NBN users is the noticeable drop in internet speed during peak hours. Network congestion is at its worst between 7pm and 11pm when many households are online simultaneously. Understanding the bandwidth limitations during these times can help you set realistic expectations for your internet speed.
What to Expect From Different Speed Tiers
Speed tiers on NBN plans dictate the maximum speeds you can achieve. Here’s what you might expect during peak hours:
- Basic (NBN 12): Max speed 12Mbps, evening speed 7Mbps
- Standard (NBN 25): Max speed 25Mbps, evening speed 15Mbps
- Standard Plus (NBN 50): Max speed 50Mbps, evening speed 30Mbps
- Premium (NBN 100): Max speed 100Mbps, evening speed 60Mbps
If your speeds are consistently below these figures, it might be time to consider upgrading your NBN speed tier, adjusting your internet plan, or switching providers to one that offers more reliable bandwidth.
Wireless vs. Wired: How Connection Type Impacts Speed
WiFi connections, while convenient, are often slower and less stable compared to wired connections. The distance from your modem, interference from walls, and the number of connected devices can all cause your internet to run slower. For critical tasks requiring higher bandwidth, like gaming, video conferencing, or streaming Netflix in high definition, using an Ethernet cable can provide a more reliable internet connection.
Boosting WiFi Performance
Simple changes like repositioning your modem, upgrading your router, or using WiFi extenders can significantly improve your wireless connection. Reducing the number of devices connected simultaneously can also help maintain a more stable internet speed. Keeping your modem firmware up-to-date and avoiding wireless congestion by choosing less crowded channels can further enhance your home internet performance.
Identifying Faults in Your Home Internet Setup
If your NBN speed is still slower than expected, it’s time to inspect your home setup. Faulty sockets, corroded cables, and poorly installed wiring can all contribute to slow speeds. In multi-unit buildings, outdated MDFs (Main Distribution Frames) may require modernisation to handle current broadband demands.
