Why NBN is Slow in Apartments (And What You Can Do About It)

If you’re living in a Brisbane or Sunshine Coast apartment and frustrated with slow NBN speeds, you’re not alone. Many apartment residents experience buffering videos, dropped video calls, and sluggish downloads, even when they’re paying for high-speed plans. The problem isn’t your router or device. It’s how NBN infrastructure handles multi-dwelling units.

Why NBN Struggles in Apartment Buildings

Shared Bandwidth Creates Bottlenecks

Most apartment buildings use FTTB (Fibre to the Building) or HFC technology. In FTTB setups, fibre runs to the building’s basement, then old copper phone lines carry the signal to individual units. As more residents stream, work from home, or game online simultaneously, everyone’s speeds drop. HFC connections face similar issues: multiple apartments share the same cable line, creating congestion during peak times (7-11pm).

Distance and Technology Limitations

The further your apartment is from the building’s fibre node, the slower your connection. NBN’s technology tiers also have hard speed caps:

• FTTN: Maximum 100Mbps, often delivers 50-80Mbps
• FTTB: Maximum 100Mbps in most apartments
• HFC: Theoretically 1000Mbps, but shared bandwidth means much lower real speeds

Even paying for the fastest tier available, the infrastructure can’t deliver consistent gigabit speeds to apartment buildings.

Signs Your Apartment Has Poor NBN

• Speeds drop dramatically in the evening
• Can’t stream HD while someone else video calls
• Actual speeds 30-50% lower than advertised
• High ping and lag in online gaming
• Connection drops during peak times

What You Can Do About It

Switch NBN Providers (Limited Impact)

Switching providers won’t fundamentally change your speed. They all use the same NBN infrastructure. You might see slightly better peak-time performance with providers that manage congestion better, but the building limitations remain.

Upgrade Your NBN Plan

Moving from 50Mbps to 100Mbps can help, but only if your building can actually deliver those speeds. Many FTTB apartments can’t reach 100Mbps consistently. Ask your provider what maximum speeds are achievable for your specific address before upgrading.

Consider Fixed Wireless Alternatives

Fixed Wireless providers offer an alternative to NBN entirely. Unlike mobile broadband, Fixed Wireless for apartments uses dedicated building infrastructure: equipment on your building’s roof connecting individual apartments. Why it’s better:

• No reliance on old copper lines
• Speeds up to 1,000Mbps actually achievable
• Symmetrical upload and download speeds
• No NBN congestion
• Faster installation (1-3 days)
• Competitive pricing

The catch: the provider needs to have already installed in your building, or requires building management approval first.

Talk to Your Strata or Building Manager

If multiple residents have poor internet, there’s strength in numbers:

• Organise with neighbours to show how widespread the issue is
• Raise it at the next AGM or general meeting
• Request alternative providers who offer building partnerships at no cost to the body corporate
• Highlight the value: Fast internet attracts better tenants, supports higher rents, and differentiates your building

5G Home Internet (Situational)

If you have strong 5G coverage, this can be a viable alternative with no installation needed. However, speeds vary significantly (100-300Mbps in good areas), signal penetration in buildings can be poor, and it won’t match true gigabit speeds. Best used as a stopgap while exploring better options.

The Bottom Line

NBN’s infrastructure wasn’t designed for modern apartment living. Shared bandwidth, copper limitations, and lack of building-specific solutions mean many apartment residents experience poor speeds, regardless of what they pay. The good news: you have options. Fixed Wireless providers are increasingly targeting apartments in Brisbane and the Sunshine Coast, offering genuinely faster speeds at competitive prices. If enough residents in your building are frustrated, you can collectively push for better solutions. Start by understanding what infrastructure serves your apartment and what alternatives are available. Your internet doesn’t have to be this frustrating.   Looking for faster internet in your Brisbane or Sunshine Coast apartment? Check if your building already has access to alternative providers like Move Up Internet, offering speeds up to 1,000Mbps without relying on NBN infrastructure.
