- Proximity to your wifi source is of course the number one factor in signal strength. The further you get from the closest wifi source the weaker the signal.
- Structural objects (buildings, walls etc) can contribute to weakening signal strength. Even a load bearing wall in a building can severely affect signal strength.
Therefore both the placement of your source as well as your location in relation to the source is important to consider. - Other materials in your area can also cause signal degradation. Along with concrete, brick and stone, foil-backed insulation foam , and even some wallpapers can dampen and damp can all hinder the radio waves. It's normally quite difficult to determine which materials are installed in your place of business, and which are causing issues, but using a Wi-Fi repeater or relocating your router can help improve things. You may want to keep this in mind if patrolling interiors such as parking garages, parking levels below ground etc.
- Electrical devices around you may also cause problems with your Wi-Fi network. Devices such as microwaves and refrigerators can interfere with the radio signal from your router; anything that communicates on the 2.4GHz frequency can interfere. It's not common for these items to cause major problems, however it could be worth keeping them in mind if you are having problems resolving any issues you have.
