Factors affecting wifi signal strength

Causes that affect wifi signal strength:

1. Router placement:

Since most routers currently adopt an omnidirectional antenna design, an upright antenna will form a signal coverage centered on the antenna. The surrounding signal is the strongest, and the up and down effect of the antenna is the weakest. Therefore, in order to achieve larger and better wireless coverage, when placing the wireless router, ensure that the signal coverage area is centered on the antenna to maximize coverage.

2. Excessively thick walls cause signal attenuation to be doubled:

Since the frequency of wireless signals is very high, when the signal passes through walls, glass or Other objects will cause great attenuation of the signal. If you want to increase the signal strength, you must try to avoid signal attenuation caused by passing through objects.

3. The antenna gain is too low:

Another important indicator that affects the strength of wireless signals is the gain of the antenna. We can use high-gain antennas to improve the signal. Strength and coverage.

4. The router’s transmitting power is low:

When the router sends out wireless signals, it will produce signal radiation. Therefore, for personal safety reasons, according to national regulations, the transmit power of wireless routers must not be higher than 100 milliwatts, but the default transmit power of some routers is only 80%, so we can try to increase the transmit power appropriately to improve the wireless signal coverage quality.

5. Interference from surrounding wireless signals:

In an environment where wifi is used, when wireless devices such as microwave ovens, wireless mice and keyboards are used, the wifi will also be affected. Interference caused by wireless signals will directly cause the wifi signal to fail to function properly in severe cases. Therefore, we can improve the strength of the wifi signal by changing the transmission frequency band of the wireless signal or eliminating surrounding wireless interference.
