Guide to Improve WiFi Reception
  1. Move your computer, phone or wireless router to a higher location.  Especially raised up off the floor or a table.   Download the Wireless Wizard and run the Aim Wireless Adapter feature to find your optimum location.  You can also try to turn your computer or phone to a different angle with the back of your laptop computer screen facing the router as most laptops put the antenna inside the screen.   If you are using a desktop computer, turn the computer so it is not between the WiFi adapter and your WiFi router.
  2. Move your WiFi router to a higher location (e.g. mouted up high on a wall or on a shelf) and closer to the center of your house if possible.  Make sure to avoid Brick walls between your computer or phone and the WiFi router.   Download the Wireless Wizard and run the Aim Wireless Adapter feature to find your optimum location.

  3. Choose a better WiFi channel.  Since WiFi only has 3 real channels that don't overlap (1, 6, 11) there is often a lot of congestion.  Download the Wireless Wizard and run the Channel Scan/Spectrum Analyzer feature to determine if other networks are interfering with your WiFi router.  If that is the case, turn off your router and turn it back on, many routers will use auto-channel scan and will automatically find a clear channel when the boot up.  If your router does not change channels, you will need to set your router to a different channel – see your manufacturer webpage settings for how to do this.
  4. Add a WiFi repeater.  These work by retransmitting your WiFi router's signal in a new area, closer to where you are connection.  The best one we have found for our customers is the PepWave, which can be purchased here
  5. Get a larger antenna for you wireless router.  Most routers come with small (3dBi) "omni" antennas which transmit the signal in a 360 degree ring around the WiFi router.  Often these can be unscrewed and replaced.  You can purchase a new antenna for your Wifi router such as this one that contains a "directional" antenna which will beam the signal in a 90 degree beam towards where you need the best coverage.   A good directional antenna can be found here or a stronger omni antenna can be found here.  Make sure to check first that the antenna will work with your router's manufacturer as there are many different types of antenna connectors, such as those shown in this table.

  6. Set your router to connect at a slower maximum speed.  Most routers will default to connect at 54Mbps, which is much faster than most Internet connections.  By using a slower speed as the maximum on your router you can increase the signal strength for connections.   (e.g. Reducing the max speed from  54Mbps to 36Mbps can more than double your signal strength) – see your manufacturer webpage settings for how to do this.
  7. Turn up the power on your router.  Most routers are set to transmit at a maximum of 17dBi of power, however, for many routers this can be increased to 20 or 23dBi – see your manufacturer webpage settings for how to do this.
  8. Reboot your router.  Often times routers get slow after a few weeks or months of heavy usage.  Simply rebooting them from time to time will often help.
  9. Purchase a higher power WiFi router (preferably 802.11n).  This should be your last resort if all of the above does not work.

Guide to Improve 3G/4G reception
  1. Move your phone or computer to a higher location or holding at a different angle.  Try holding your phone in your hand and using the speaker, then try to raise your hand up.  Different phones will work better when holding at different angles, for example an iPhone works best when holding flat in your hand, horizontal to the ground.
  2. Find out where the nearest cell tower is to where you are connecting (by going here) and then move your phone or computer towards an outer wall or outside your house closest to the nearest cell tower.   You can also manually locate the best tower by walking around and moving towards the direction where your signal gets better.  When you have 5 bars (or -50SNR) you are nearby a tower.
  3. 3G/4G signals tend to work the worst during the height of the summer (e.g. July/August in the Northern Hemisphere, January/February in the Southern Hemisphere) due to trees and best in the winter.  During the summer months, you may need to go outdoors or near an outer wall to make a call.
  4. Remove your case on your phone.  This can often lower your signal by a full bar or more.  Even if this is a temporary solution, it will help.
  5. Purchase a 3G/4G cellular repeater, which will retransmit the towers signal throughout your home or business.  A good guide for choosing a 3G/4G repeater can be found on this site here
