Boost your router's signal

A wireless router normally has a range of 30 meters or more. However, there are factors that can lower this range. Interference can be caused by metal, other routers, or other devices that use wireless frequencies (such as cell phones and microwave ovens). Fortunately, there are ways to boost your signal. Here are a few.


Method 1 of 5: Look for interference

Boost a Wifi Signal Step 1

Step 1. Move devices that might interfere in the 2.4 Ghz frequency range

Optionally, you can buy a device with which you can analyze the wireless network, so you can easily find the interference source. Here are some examples of possible jammers:

  • DECT telephone.
  • Microwave.
  • baby monitor.
  • Burglar alarm.
  • TV remote control.
  • Garage door openers.

Step 2. Check the signal strength of your router in combination with these devices

Turn the devices off and on and see if there is a difference, so you can check if a particular device is causing the problems.

Method 2 of 5: Choose a different channel

Step 1. Change channel on the router

Routers can transmit on different channels, from 1 to 11. Choose a channel where you have the least interference from other wireless networks.

Step 2. Use software to analyze which networks in your area are using which channel and configure your system to use a channel that no one else is using

Method 3 of 5: 802.11n

Boost a Wifi Signal Step 5

Step 1. Check which protocol your router uses

The 802.11n standard is the best choice because it gives you greater range and signal strength than older standards such as 802.11 a/b/g.

Method 4 of 5: Move the router

Boost a Wifi Signal Step 6

Step 1. Choose a different location for your router

Sometimes the simplest solution is the best. All you need to do is find a good spot for the router.

  • Position the router as high as possible to increase the range.
  • Place the router in the middle of your house so that you have coverage everywhere.
  • Move the routers closer to the computers if possible.
  • Do not place the router near metal objects such as metal cabinets or desks.
  • Do not place the router near a microwave oven or a DECT telephone, they use the same 2.4 Ghz frequency.

Step 2. Place the router as far away from the neighbor's router as possible

This is especially important if you live in a building where each floor has its own router.

Method 5 of 5: Upgrading the router

Boost a Wifi Signal Step 8

Step 1. Increase the broadcast strength of your router

Check the manual for the router to see if you can increase the strength, i.e. the strength with which the signal is sent. With most routers you can increase this to 50 mW. Be careful that the router does not overheat.

Step 2. Replace the antenna

Remove the antenna from the router and replace it with a stronger antenna. This is not possible with all routers.

Step 3. Place a repeater

A repeater is a device with which you can extend the wireless signal. The repeater takes the signal from the router and retransmits it amplified.

Wireless repeaters are getting cheaper and cheaper, you can easily find them on the internet or at the computer store around the corner

Step 4. Place a WiFi booster

Connect a WiFi amplifier, also called a booster, directly to the router. A booster is often cheaper than a repeater because only the signal is amplified and not the range.

Step 5. Make a reflector out of cardboard and aluminum foil

Note: the signal is amplified, but also narrowed.

  • Take a piece of aluminum foil and stick it on a piece of paper or cardboard.
  • Stick another piece of paper to the inside of the reflector so that it curves slightly inwards.
  • Make two holes in the piece of paper so that you can attach the reflector to the antenna.
