Homes are almost as diverse and unique as the people inside of them. Size, shape, materials, and proximity to neighbors’ networks all impact WiFi strength and reliability.
Materials like brick, stone, concrete, metal, and glass all cause problems. Plus, because of their shape, 5GHz waves don’t go through walls and furniture as well as 2.4GHz waves.
WiFi waves are just radio waves, so as you get farther from the access point, their strength diminishes. In general, the higher the frequency of radio wave — the newer 5GHz band, for example — the better the performance, but the shorter the range.
Depending on the density of your neighborhood, you could have 50 or more WiFi networks nearby, all competing with yours for limited available radio spectrum. The 5GHz spectrum is much less crowded than 2.4GHz.
Believe it or not, household appliances like refrigerators, water heaters and remotes can interfere with your WiFi signal. The more stuff you have, the worse it can be.
