Upgrading to a faster NBN plan does not always mean you need a new router. However, if your existing router is several years old, uses Wi-Fi 5 or earlier, or only has Gigabit Ethernet ports, it may limit the speeds available from newer NBN plans.
For NBN 500, 750 and 1000, a good Wi-Fi 6 router may be enough. NBN 2000 is different. To make proper use of a 2Gbps service, the router needs networking hardware capable of more than 1Gbps.
There is another catch: a faster router does not automatically mean faster Wi-Fi in every room. Walls, floors, distance and access-point placement can still become the bottleneck.
What Router Do You Need for Each NBN Speed?
A useful starting point is to match the router’s Wi-Fi generation and Ethernet capability to the NBN speed tier.
| NBN plan | Good starting point | What to check |
| NBN 500 | Wi-Fi 6 | Gigabit WAN and good 5GHz coverage |
| NBN 750 | Wi-Fi 6 | Gigabit WAN and strong coverage |
| NBN 1000 | Wi-Fi 6, 6E or 7 | Gigabit WAN minimum |
| NBN 2000 | Wi-Fi 6E or Wi-Fi 7 | 2.5Gbps or faster WAN |
NBN recommends Wi-Fi 6 or newer when trying to get the best performance from faster internet connections.
How Can You Tell If Your Current Router Is the Bottleneck?
A router upgrade becomes worth considering when:
- The router uses Wi-Fi 5 or an older standard
- Wired speed tests are much faster than wi-fi tests
- The router only has 1gbps ports, and you have NBN 2000
- Wi-fi speed falls sharply as you move away from the router
- Performance becomes poor when several devices are online
A particularly useful test for NBNis to compare a wired Ethernet test with a test taken beside the router. If Ethernet performs well but Wi-Fi does not, the NBN connection itself may not be the main problem.
Will Buying a New Router Fix Slow Wi-Fi?
Not necessarily.
One powerful router may work well in a smaller, open-plan property but struggle in a large or double-storey home. Brick walls, concrete floors, metal, mirrors and appliances can all reduce wireless signal strength.
It doesn’t matter if you have a fast NBN plan, weak Wi-Fi can remain a problem upstairs even after buying a newer router.
For more complex homes, the answer may be better network design rather than a more expensive router. Wired wireless access points can distribute Wi-Fi closer to the areas where it is actually used.
In Brisbane, Smart WiFi’s residential Wi-Fi installation service includes property assessment, cabling and wireless access-point placement rather than relying entirely on one central router.
Wi-Fi 6 vs Wi-Fi 7: Which Makes Sense?
For NBN 500, 750 and many NBN 1000 households, Wi-Fi 6 can still be perfectly fine.
Wi-Fi 7 becomes more relevant for NBN 2000, newer multi-gig devices, and households planning their network for the next several years. It also introduces improvements designed to increase wireless capacity and efficiency.
So, do you need Wi-Fi 7 for NBN 1000? Usually, no. Wi-Fi 6 can support a gigabit-class connection under the right conditions. Wi-Fi 7 offers more headroom, but device capability, signal strength and placement still matter.
We have covered the newer standard in more detail in Wi-Fi 7: What Homeowners and Businesses Need to Know.
When Should You Call a Wi-Fi Professional?
A professional network assessment becomes more useful when the issue is not simply an old router.
Examples include:
- Fast Wi-Fi beside the router but poor speed upstairs
- Dead zones in bedrooms, offices or outdoor areas
- A large or multi-storey property
- Security cameras or smart devices regularly dropping offline
- Several access points being required
- Uncertainty over where access points should be installed
A Wi-Fi site survey can identify coverage gaps, interference and suitable access-point positions before equipment is installed.
Upgraded your NBN but still not getting reliable Wi-Fi throughout your home? Smart WiFi can assess your setup and help identify whether the issue is your router, coverage, cabling or access-point placement.
Frequently Asked Questions
Do I need a new router for NBN 500?
Not automatically. A good Wi-Fi 6 router with Gigabit Ethernet should generally be capable of supporting NBN 500. Coverage, router placement and the capabilities of your phones, laptops and other devices still affect the speeds you actually receive.
Do I need a new router for NBN 750?
Older Wi-Fi 5 equipment may become a limiting factor. A Wi-Fi 6 router with Gigabit Ethernet is a good starting point for NBN 750, particularly where several devices use the connection at the same time.
Do I need a new router for NBN 1000?
Possibly. A router for NBN 1000 should have at least Gigabit Ethernet and preferably Wi-Fi 6 or newer. Wi-Fi 6E or Wi-Fi 7 can provide additional capacity, but they are not essential for every household.
Do I need a special router for NBN 2000?
Yes, if you want to make proper use of the full connection. A 2.5Gbps router for NBN 2000 needs at least a 2.5Gbps WAN port. Multi-gig LAN ports are also useful when connecting high-speed wired devices.
Why am I not getting my full NBN speed over Wi-Fi?
The router may only be one part of the problem. Distance, walls, interference, device capability, router position and poor access-point placement can all reduce wireless performance. Testing close to the router and then in problem areas can help separate an NBN speed issue from a Wi-Fi coverage issue.
