What router do I have and how does it work?

Our Cuckoo experts have selected the Technicolour DWA0122 for you. It's compact, easy to use and gives you the fast speeds you need at an affordable price.

But we're always open to new ideas; so if you're a router aficionado, let us know if you think we should try something else - maybe via the Cuckoo community.

Here are what all the lights mean:

This is your overall status light.

  • If it's green, surf away 🌊 When the status line is green all other lights will be off; but tap the status light and you'll briefly see all the other lights come on too.
  • If it's orange, don't worry. It's probably warming up, or sorting out a short-term issue automatically πŸ‘
  • If it's red for more than 10 minutes, it means you're not connected to the internet. To resolve:
    - Check all cables are securely connected
    - Your router likes to stay cool. ❄ Make sure there's enough air flow around it and don't keep it in a hot place
    - Try performing a factory reset of the router (see here for more details)

This shows you whether you're able to connect to the core network (the telephone exchange normally someone nearby).

  • If it's off, then there's no connection or no cable between your router and the exchange (no sync). This may be because your router isn't turned on, or your switch-on date hasn't happened yet, or there's a physical issue with the cable near your home. See below for more info on no sync issues
  • If it's flashing green then it's currently synchronising with the exchange
  • If it's solid green, it's in sync with the exchange

This shows you whether you can download and upload data packets (e.g. access web pages) via the network.

  • If it's solid green, it's connected πŸ‘
  • If it's flashing green, there's a data transfer
  • If it's flashing red, then it's trying to connect
  • If it's solid red, there's an issue. This might be because you've plugged in your router ahead of the activation date. If the solid red light persists, the best thing to do is a factory reset of your router (see here)
  • If it's off, then there's no connection, or it's disabled.
Wireless 2.4 and 5 GHz

You don't really need to worry about this one, but if you're interested...

Your routers are very clever. πŸ€“ They automatically connect you to the internet over the best possible frequency for your device and location.

If you're far away from the router, they'll connect you via 2.4GHz. This is a slightly slower speed but has a wider coverage. If you're near the router, it will switch you onto 5GHz, which is more powerful and so gives you a faster speed.

Most of the time both lights will be on, as the router will be connecting different devices at both frequencies.

In short, you can sit back and relax, and let the router manage your connection.


This stands for Wi-Fi Protected Setup. It's a wireless network security standard that can connect a router and wireless devices faster and more easily - and without needing to use your normal password.

However, it can be compromised, so don't rely on it entirely. We advise you stick to the basic username and password method for connecting to Wi-Fi. πŸ‘

To connect a device using WPS PBC (Push Button Configuration):

  1. First make sure that your Wi-Fi device supports WPS PBC and you know how to start it. For more info, look at your device manual.
  2. On the side of your router, briefly press the WPS button and then release it. The WPS light should start blinking orange.
  3. Within two minutes, start the WPS PBC on your Wi-Fi device. You will probably have to do this in one of the following ways:
    - Press a WPS button on your device
    - Start WPS (PBC) on the user interface of your device
    - Open a list of available networks and select the Network Name mentioned on the Wi-Fi settings label (on the bottom of your router)
  4. After a maximum of two minutes, the WPS light will briefly be in one of two states:
    - Solid green: it worked πŸ™Œ
    - Blinking red: device could not be found. πŸ€” Try again or connect your wireless device manually in the normal way (i.e. with your password)

WPS not working? To protect your security, your router will automatically switch off WPS if it thinks there's someone nearby who's interfering with your network. First generation Macs also aren't very good at working with WPS, so if you have one of those in the house, it may struggle...


This shows you whether you're connecting to the internet via an Ethernet cable. If you want the very fastest speeds, Ethernet is the way to go πŸš€

  • If you are connected by an Ethernet cable, this should be solid green
  • If you're currently transferring data over Ethernet, it will be flashing green
  • If you're just using Wi-Fi, this will stay off

You don't need to look at this one. Ever. πŸ™Œ

Wireless on/off

This shows whether the router is turned on or not.

  • If the light is off, you need to plug in the router and press the power button
  • If it's orange, the router is starting up
  • If it's green, you're all good πŸ‘
How to troubleshoot a no sync issue with your broadband

There are a bunch of reasons why you may have a no sync message on your router (i.e. your broadband light isn't on), including:

  • Issues with your internal wiring
  • Issues with the router (rare)
  • Faulty Exchange equipment
  • Faulty Port (Exchange/Cabinet)
  • Underground Cabling
  • You haven't reached your activation date yet
