UniFi or your internet provider's router: what changes and when it's worth it
By IPProtec · · 5 min read
Quick answer
The internet provider's router is a single device acting as router, switch and WiFi at once, with limited configuration options. A UniFi network splits those functions into dedicated devices (gateway, switches and access points), which makes it possible to cover the whole property, create separate networks and see what is happening on the network. It does not replace the provider's connection: it is installed behind it.
The provider's fibre line usually works well. What fails in most homes and small businesses is what comes after it: a single device, placed where the cable came in, trying to give WiFi to the whole building.
What each one does
| Aspect | Provider's router | UniFi network |
|---|---|---|
| Devices | One for everything | Dedicated gateway, switches and access points |
| WiFi coverage | Whatever reaches from its location | Designed: one access point per area |
| Where the WiFi is | Where the fibre comes in | Where the network is used |
| Separate networks | Main and, sometimes, guest | Several networks and VLANs with firewall rules |
| Visibility | Basic device list | Traffic, clients, coverage and alerts per device |
| Remote access and VPN | Limited or none | Built-in VPN and remote management |
| Cameras and doors | Not applicable | On the same infrastructure and console |
| Who manages it | The provider | The owner of the installation |
How they work together
The UniFi network connects to the provider's line; it does not replace it. There are two usual ways to do it:
- With the provider's router in bridge mode, or with the ONT connected straight to the UniFi gateway: the UniFi gateway manages the whole network. It is the cleanest option, but it depends on the provider allowing it.
- With the UniFi gateway behind the provider's router, which keeps working as before with its WiFi switched off. It works with any provider and is enough for most homes.
When nothing needs to change
In a small flat, with the router in a central position and few devices, the provider's equipment is usually enough. If the problem is a single room without coverage, it can sometimes be solved with one wired access point, without building a full network.
When it's worth it
- Areas with no coverage or dropouts: upper floors, distant rooms, the garden.
- Businesses offering WiFi to customers that must keep it apart from their internal network (tills, computers, cameras).
- Remote work connecting to the company over VPN.
- Smart-home devices or cameras that are best isolated from other equipment.
- The need to know which device is failing when something goes wrong, instead of rebooting the router.
FAQ
Do I have to return the provider's router?
No. The UniFi network connects to it or to the ONT. The usual approach is to leave it in place and switch off its WiFi.
Does it increase the speed I pay for?
No. The connection speed is set by the provider. What improves is that this speed actually reaches every area and device.
Does it still work if I change provider?
Yes. The internal network is independent of the provider: when you switch, the gateway is simply connected to the new line.
