10 tips to improve your Wi-Fi and Internet

Tip 1: Get close to your b-box modem or Wi-Fi Booster

When using your mobile 'phone, tablet or computer, get as close as you can to your b-box or Wi-Fi booster, because the further away the Wi-Fi is, the less powerful it becomes.

The quality of your Wi-Fi also depends on any obstacles between your device and the b-box or Wi-Fi booster because the Wi-Fi signal moves in a straight line. Anything which cuts your device off from the b-box or Wi-Fi booster will weaken the signal, including things such as concrete, metal, brick or simply insulated walls. The Wi-Fi signal can also be weakened by furniture such as mirrors, shelves, wardrobes, etc.

Tip 2: Position your b-box at the centre of your home

Where should you put the b-box?

  • The best place to position the b-box is at the centre of your house, in an open space (not inside a cupboard) and more than a metre from the ground. This will give you better Wi-Fi coverage.
  • Always try to keep the b-box or Wi-Fi booster over a metre away from any other electrical appliances in order to avoid any interference.
  • If your b-box is in the basement, the Wi-Fi signal will be very weak, so it is a better idea to install the b-box on the ground floor using an RJ11 cable which is long enough to reach from the socket in your basement.
  • If it is too complicated to move your b-box somewhere else, you can either ask our technicians for help or order a Wi-Fi BoosterOpens a new window to extend the Wi-Fi coverage throughout the house.

How should you position the b-box?

Position your b-box so that the LEDs are facing outwards - they must not be facing the wall or the floor. If the b-box is installed in the basement, position it so that the LEDs are facing upwards in order to make it easier for the Wi-Fi signal to reach the floor above.

Tip 3: Ethernet cables are good too!

Wi-Fi is great, but using an Ethernet cable to connect the b-box to your computer, decoder or console also has its advantages:

  • You’ll get a faster Internet connection.
  • There'll be no problems with interference from other devices.
  • You won’t run any risk of overloading the Wi-Fi.
  • You can reach places which are too far away for Wi-Fi, as long as you’ve got an Ethernet socket there.

You can buy Ethernet cables at any electronics shop, but if you wish to have Ethernet sockets fitted in your house it is a better idea to contact an electrician or have it done when you’re having renovation work carried out in your home. This is not a service offered by Proximus.

Check that your Ethernet cables aren't too old. It is best to use RJ45 Ethernet cables which are at least cat 5e. Use them to connect as many devices as possible, especially the ones which use the most bandwidth, such as the decoder, console and Wi-Fi Booster.

Tip 4: Use Smart Wi-Fi so that you’re always on the right frequency

If you’ve not already done so, use your MyProximus applicationOpens a new window to switch on Smart Wi-Fi. Smart Wi-Fi makes sure that your device always connects to the best Wi-Fi frequency, which is pretty useful!

There are two Wi-Fi frequencies on a 3/3V+ b-box - one at 5 GHz and the other at 2.4 GHz:

  • 2.4 GHz: this is the most commonly-used Wi-Fi frequency. It usually offers the greatest range and better coverage, although at a lower speed. Signals at this frequency find it easier to make their way through walls and thick objects. Most modems and Wi-Fi compatible devices operate on the 2.4 GHz frequency which can, unfortunately, cause interference and make the Wi-Fi less efficient.
  • 5 GHz : Overall the 5 GHz band offers higher speeds, but the trade-off is that they don’t have such a large range and the coverage isn’t as good. The 5 GHz frequency is less sensitive to interference.
Turn Smart Wi-Fi onOpens a new window so that your device automatically switches to the best frequency.
Tip 5: Watch out for interference

There are many electrical appliances which can disrupt your Wi-Fi, such as microwave ovens, alarm systems, security cameras, radiators, doorbells, lighting, baby monitors, etc. There is no miracle solution; you simply have to take this into account when you set things up. So keep away from any electrical appliances which disrupt the Wi-Fi and get as close as you can to the b-box or Wi-Fi booster. You can avoid most of these interference problems by simply turning Smart Wi-Fi onOpens a new window !

Tip 6: Old devices can slow the Wi-Fi down

If you have a computer, tablet or mobile telephone that is more than five years old, it’s best not to connect it to your Wi-Fi as it may slow the other devices that are connected down, even the newest ones!

If possible, use at least a cat 5e Ethernet cable to connect them, switch them off or turn off their Wi-Fi when they aren’t being used.

Tip 7: Don't overload your Wi-Fi

The quality of your Wi-Fi signal also depends on how you use it - downloading very large files (e.g. torrents) or using a number of devices at the same time will affect the quality of your Wi-Fi.

Smart Wi-FiOpens a new window is available via the MyProximus application and can help you to identify any devices which are overloading your Wi-Fi network.

Tip 8: Compare with other devices

If your Internet connection is very slow, use another device to compare their speeds with our speedtest on the web. If you’re getting a better connection using another device, your device probably has a problem or else its Wi-Fi is not working as well as it should. Restart your device or use another device to browse the Web using Wi-Fi.

Tip 9: Extend your Wi-Fi with a Wi-Fi Booster

If you live in a house or a large flat, the Wi-Fi signal from the b-box may not be powerful enough to cover all of the rooms. In this case you can use a Wi-Fi booster to extend your network. The MyProximus appOpens a new window will help you to find the best place to put it in your home.

Tip 10: Test your line

If your connection is very slow or drops constantly:

  1. Connect a laptop to your b-box using at least a cat 5e network cable (or a new Ethernet cable).
  2. Measure your speed using https://pxs.speedtestcustom.com/Opens a new window . Take a note of the speed you managed to get.
  3. Disconnect the Ethernet cable, connect to Wi-Fi and measure the speed again using
If there is only a small difference in speed, your modem needs to be restarted:
  1. Switch the b-box off by pressing the start/stop button on the back.
  2. Wait for around ten seconds
  3. Switch the b-box back on again.
