Choosing a router is confusing because the marketing competes on numbers: AX1800, AX3000, BE9300. Those numbers are the theoretical sum of every frequency band, and no single device ever experiences them.
A more useful order is the reverse: start with your needs, then determine the specification.
Three questions before looking at any product
1. How fast is your subscription?
A router can't make the internet faster than what you bought. If your plan is 50 Mbps, a mid-range AX1800 router already far exceeds your bandwidth needs. Money is better spent on coverage than on speed figures.
2. How large is the building, and what's it made of?
A 45 m² single-storey home has completely different needs from a 150 m² two-storey house with concrete walls. Above roughly 100 m², or in a multi-storey building, one router, however powerful, usually loses to two simple, well-placed access points.
3. How many devices are active at once?
Count everything: phones, laptops, smart TVs, consoles, cameras, watches, smart bulbs. Above 20 starts to strain an entry-level router, regardless of subscription speed.
Rule of thumb: if your complaint is "the signal disappears in the back bedroom", the answer is adding an access point. If it's "everything slows when everyone's online", the answer is a router with a decent processor and Wi-Fi 6.
Translating the terms on the box
| Term | What it means | How important |
|---|---|---|
| Wi-Fi 6 (802.11ax) | A standard that's more efficient with many active devices | High |
| Wi-Fi 6E | Adds the uncrowded 6 GHz band | Medium |
| Wi-Fi 7 (802.11be) | Wider channels and simultaneous multi-band operation | Low for now |
| OFDMA | Splits a channel so many devices are served at once | High |
| MU-MIMO | Serves several devices in parallel | Medium |
| Beamforming | Aims the signal towards device positions | Medium |
| WPA3 | The latest encryption generation | High |
| 2.5 GbE port | A wired port above 1 Gbps | Low unless your plan is >1 Gbps |
| Number of antennas | A rough indicator of range and data streams | Low as a standalone number |
The two terms most worth attention are OFDMA and WPA3. The first solves a real problem in modern households, many small devices frequently sending short bursts of data. The second is a security baseline.
Matching router class to situation
Apartment or small home, <10 devices, plan <100 Mbps
A Wi-Fi 6 router in the AX1500–AX1800 class is more than enough. Prioritise brands with a good firmware update record over speed figures.
Mid-size two-storey home, 10–25 devices
Choose a two-unit Wi-Fi 6 mesh system, or one main router plus one access point joined by cable. A wired link between nodes gives the best result.
Large home or many concrete walls
Three mesh nodes, ideally with wired or dedicated-band backhaul. Adding nodes is more effective than upgrading the class of a single device.
Café, clinic, or small office
Use business-class access points with VLAN and captive portal support, managed through a central controller. Home routers aren't designed for dozens of users changing every hour.
Heavy users, plan >500 Mbps
This is where Wi-Fi 6E or Wi-Fi 7 starts to make sense, particularly if your main devices already support it and you need wired ports above 1 Gbps.
What buyers often overlook
Long-term firmware support
A router runs 24 hours a day and connects directly to the internet. A brand that stops issuing updates after two years leaves you with a permanent security gap. Check the update history of that brand's previous models.
The quality of the management app
You'll interact with this app every time you add a device, create a guest network, or investigate a problem. A bad app leaves good features unused.
A genuinely isolated guest network
Some routers offer a "guest network" that can still see other devices. Make sure there's a client isolation option if you frequently host visitors.
Heat and ventilation
An overheating router slows down and doesn't last. Devices with a well-ventilated body, kept out of enclosed spaces, last far longer.
Easy DNS changes and QoS settings
These two settings are the ones home users need most often. Routers that hide them behind a paid subscription are best avoided.
Security features that should be present
The router is the entrance to your entire network. The following capabilities deserve to be minimum requirements rather than bonuses:
- WPA3, or WPA2-AES at minimum. Avoid devices still offering WEP or TKIP as a primary option.
- A guest network with client isolation. Guests get internet access without seeing other devices on your network.
- Automatic firmware updates. Most users never check for updates manually.
- A unique factory administrator password. Routers still shipping with admin/admin are best avoided.
- UPnP that can be turned off. The feature helps some applications, but widens the attack surface if left on without need.
The first ten minutes with a new router
Change the administrator password
The most important step, and the most frequently skipped. Use a password different from the Wi-Fi one.
Update the firmware
Newly purchased devices often ship with firmware a year or more old.
Set encryption to WPA3 or WPA2-AES
If an older device doesn't support it, use mixed mode rather than downgrading the whole network.
Create a separate guest network
Enable client isolation on it.
Turn off WPS
The convenience it offers isn't worth the risk.
Record the configuration
Save a settings backup so it's easy to restore if something goes wrong.
When a router needs replacing
Routers have no fixed lifespan, but a few signs indicate the time has come:
- The last firmware update was more than two years ago and the brand has ended support.
- The device needs periodic restarts to stay stable.
- It only supports WPA2 with TKIP and can't be updated.
- It can't handle the number of devices you now have.
- The body feels very hot in normal use.
Absent those signs, replacing a router just because a new generation exists rarely makes a noticeable difference.
Conclusion
The right router is the one that suits your building and your habits, not the one with the biggest number. For the majority of Indonesian households in 2026, a single mid-range Wi-Fi 6 unit with WPA3 and a decent app resolves nearly every complaint, provided it's placed correctly.
If you're torn between adding a router and adding an access point, read the comparison of mesh, repeaters, and access points. To understand the differences between standards, see Wi-Fi 5, 6, 6E, and 7 explained.
Frequently asked questions
Is an expensive router automatically faster?
No. Your maximum speed is still capped by your subscription. An expensive router wins on coverage, stability when many devices are active, and management features, not on peak speed beyond the service you bought.
What does the AX3000 figure in a router's name mean?
AX indicates Wi-Fi 6, while 3000 is the theoretical sum of speeds across all bands. No single device ever reaches that number; treat it as a class marker, not a performance promise.
Should I replace the router my provider gave me?
If its coverage is adequate and you have no complaints, no. Replacement is worth considering if your home is large, you have many devices, or the supplied router is still early-generation Wi-Fi 4/5.
Is Wi-Fi 7 worth buying now?
For most households, not urgently. Its full benefit only appears with Wi-Fi 7 client devices and a subscription above 500 Mbps. Wi-Fi 6 or 6E offers better value per rupiah right now.
