NBN upgrades mix-up: Do you need a new modem to get faster speeds?

There's a lot of frenzy around the upcoming NBN speed upgrades and how millions might miss out on faster speeds if they don't have the right hardware. But it's not as critical as you might think.

Unless you're into tech, modem chats are likely not your cup of tea. And that's often why they're overlooked when you're scratching your head, wondering why your internet connection isn't up to speed.

It could be your provider, you may not be on the right plan for your internet use, or it could simply be an outdated modem.

However, a lot of us will be thinking about the hardware used to get us online as NBN rolls out faster speeds (for free!) in just under 10 days.

Not familiar with the upcoming NBN upgrades? Here's a quick overview first, before we chat modems

We have a handy guide on everything you need to know about the upcoming NBN speed upgrades, but the somewhat short version to give you context is:

• From 14 September 2025, NBN will boost speeds across NBN 100, NBN 250 and NBN 1000 plans for those on a Fibre to the Premises (FTTP) or Hybrid Fibre Coaxial (HFC) connection. Check your address if you're unsure of your NBN connection type.
• NBN 100 will jump from 100Mbps download and 20Mbps upload to 500/50Mbps, making it five times faster.
• NBN 250 will be bumped up from 250/25Mbps to 750/50Mbps.
• Upload speeds on NBN 1000 will double, with plans offering up to 1000/100Mbps speeds.
• NBN Co will also introduce a new Hyperfast speed tier called NBN 2000.

Your existing provider will notify you if you're eligible for the speed upgrades. Some, such as Telstra, have already started sending out emails.

So, do I need a new modem for these NBN speed upgrades?

It depends on the modem or router you're currently using. According to Dodo, if your modem is more than five years old, it may struggle to handle the fastest speeds on NBN 500 and above.

Like smartphones, modems come in different generations that affect performance. The newer the model, the better, especially if you have many, many devices connected to the internet.

• A Wi-Fi 6 or Wi-Fi 7 modem will give you the best chance of reaching top speeds on NBN 500 plans and higher.
• For NBN 2000, NBN Co will also need to upgrade the NTD (network termination device) at your home, and a Wi-Fi 7 modem is recommended.
• Before rushing to upgrade, check the specs of your current modem to see how up to date it is. Your provider can help if you're unsure.

But it's also not just how new your modem is. According to a Vodafone media release, "in many Australian homes, the modem ends up in a spot that suits the network connection but not necessarily where people use the internet."

Sometimes, if your home is spread across two floors, you may need a Wi-Fi mesh system to help extend coverage and reduce dead spots.

But, don't rush to upgrade your modem just yet...

Now, let's say you're on an NBN 100 plan with a Wi-Fi 4 or Wi-Fi 5 model, and you get an email saying your plan is being upgraded to NBN 500 at no extra cost.

In that case, there are two ways to look at it:

• You'll still get up to 100Mbps with your current modem, which may be enough for your needs, and you can carry on.
• But if you do want faster speeds, let them roll out and then decide if you want to upgrade your tech. Stand by for now instead of rushing.

Are providers offering any modems with their plans?

If you're keen to board the speed upgrade train, then it's worth comparing modem costs and terms and conditions, especially if you decide to switch providers for the best offer when the upgrades roll out.

Lately, telcos like TPG, Vodafone and Telstra have started offering "faster and better modems". Here's how different modem T&Cs can vary:

• Some providers will ask you to BYO modem or buy one from them upfront. The average cost of modems in our database is around $150, but they can go upwards of $300 depending on the model.
• Providers like Telstra will give you one for $0. If you cancel before 24 months, you'll just need to return it or pay a $200 non-return fee.
• Optus lets you BYO modem, or you can get a Wi-Fi 6 one with 4G backup for $0 if you stay connected for 24 months (normally $306). If you leave early, you'll need to pay off the remaining cost of the device.
• Similarly, Vodafone is offering a Wi-Fi 7 modem for $0 if you stay on for 24 months (normally $366). You'll have to pay off the remaining cost of the hardware if you leave early.

All of this information is good to know, but the bottom line is you don't need to upgrade straight away. Run a speed test now, and then check your performance in a few months.
