The last two jobs I worked on, we had to reduce the signal strength to make the Wi-Fi devices work correctly. This is why people do Wi-Fi surveys looking at signal strength, signal to noise ratio and signal to interference ratio. You can have a 100% signal strength and zero wireless. Please no, stop telling people it's all about signal strength, the number one cause of WiFi issues I have to deal with, in customer warehouses, is nothing to do with signal strength, all to do with too much strength, there are many factors that affect signals. This means that three and four bars indicate a good signal quality and anything below indicates a weak signal. In the case that you're viewing the Wi-Fi icon to find out the performance of the connection, consider that each bar (including the dot) represents around 25 percent of signal strength. If you're trying to determine the perfect placement on the house or office for the best signal, run the above command where you typically use your computer, then move around to another place or room, and re-run the command to find out the signal strength in the new location. Anything below 60 percent means that you have a weak signal, and you should consider moving the device closer to the access point or relocating the access point to the middle of the house or office. If you see a signal above 70 percent, it's still good for light web browsing and managing emails. Once you complete the steps, if you see a signal quality between 80 and 100 percent, then the connection is reliable.
