We Have NBN, So Why Is Our Internet Still Bad? A Perth Business Guide

We have NBN, so why is our internet still bad? It’s one of the most common questions we hear from Perth businesses. Despite being connected to the National Broadband Network, many organisations still experience slow speeds, frequent dropouts, and frustrating support experiences.

This guide explains why business NBN performance often falls short of expectations, what causes poor reliability, and how Perth businesses can fix it.

Why Do Perth Businesses Still Have Bad Internet on NBN?

Having NBN does not automatically guarantee fast or reliable internet. The reality is that NBN performance depends on several factors, many of which are often overlooked by businesses.

1. Your NBN Technology Type Matters

Not all NBN connections are created equal. The technology type servicing your premises has a huge impact on speed and stability.

• FTTP (Fibre to the Premises) – Best performance and reliability
• FTTN (Fibre to the Node) – Performance depends on copper quality
• FTTC / HFC – Can be inconsistent under load

If you’re unsure which NBN type you have, read our guide on FTTP vs FTTN and other NBN technologies.

2. Business Internet Plans Are Often Under-Provisioned

Many businesses unknowingly use residential-grade NBN plans. These plans:

• Have lower contention ratios
• Are deprioritised during peak hours
• Lack service-level guarantees

Choosing the right business internet service provider in Perth is critical for performance.

3. NBN Congestion and Peak-Time Slowdowns

NBN congestion is a major reason businesses say, “We have NBN, so why is our internet still bad?” During peak times, shared infrastructure can slow speeds dramatically if your provider hasn’t purchased enough capacity.

4. Poor Internal Network Setup

Even with a good NBN service, internal issues can destroy performance:

• Outdated routers or firewalls
• Poor Wi-Fi coverage (using an all in one router that doesnt provide sufficient wifi coverage)
• No traffic prioritisation for business-critical apps

This is where professional IT consulting in Perth can make a significant difference.

Why Business NBN Support Feels So Bad

Another common frustration is poor support. Many NBN providers rely on offshore call centres, slow escalation paths, and limited fault ownership.

Business-grade internet services should include:

• Local Australian support
• Defined response times
• Proactive monitoring

If your provider can’t offer this, or it is a major call centre service with no onsite support, it may be time to consider a better-supported IT support and helpdesk service.

How Perth Businesses Can Fix Bad NBN Internet

1. Review Your Business Internet Provider

Not all business internet service providers are equal. Look for providers that specialise in business NBN, not residential plans rebranded for companies.

2. Upgrade to the Right NBN Technology

Where possible, upgrading to FTTP can dramatically improve speed and reliability. In some cases, fixed wireless, enterprise Ethernet, or failover connections may be better options.

3. Implement Redundancy and Monitoring

Serious businesses don’t rely on a single connection. Backup links and proactive monitoring ensure uptime even when NBN has issues.
