How to effectively enhance wireless signal strength How to check wireless router signal strength

Many families have installed broadband, and with the popularity of smart phones, they have also installed and used wireless routers. For most ordinary families, a single router can basically meet the family's usage needs. Regarding the issue of wireless router signals, read the following article to learn more!

How to effectively enhance wireless signal strength

After the wireless signal passes through the wall, the signal attenuates severely. When passing through the load-bearing wall of the concrete structure, the signal attenuates by 15~30dB. We can use multiple wireless routers to form a network and realize the "wired penetration of the wall" of the wireless signal.

Networking of multiple wireless routers: Connect the LAN port of the cascade router to the LAN port of the upper router, turn off the DHCP service of the cascade router, and set a management IP address in the same network segment as the main router. The wireless wifi name and password should be consistent with those of the upper router.

How to Check Wireless Router Signal Strength

The strength unit of wireless router wireless signal is dBm, generally between -90 and 0. We can download a mobile phone APP to test the strength of wireless signal, such as cellular-z. Generally:

The signal strength is very good between -50 and 0, and the user perception is good;

The signal strength is good between -70 and -50. The user experience is slightly worse, but there is no obvious impact on the experience;

The signal is not very good below -70, and the perception is poor during use.

What are the types of wireless router antennas?

The antennas of wireless routers are generally divided into two categories, one is directional antenna and the other is omnidirectional antenna. Directional antenna, as the name implies, is an antenna with a certain direction. The horizontal direction is shown in the figure below, and it radiates in a certain angle range (generally this horizontal angle does not exceed 120°). The advantages of directional antennas are higher power and stronger penetration performance, and they are usually used for outdoor devices. Omnidirectional antennas, as the name implies, have no direction and achieve 360-degree coverage. Omnidirectional antennas have lower power and weaker penetration performance than directional antennas, and are often used in home broadband routers.

If the device and the router are on the same level, such as on the same floor of a home, the router antenna needs to be upright and perpendicular to the ground. This ensures that the radiation intensity of the wireless signal is as strong as possible. Similarly, if the router is placed on the first floor and the mobile phone is used on the second floor, the antenna needs to be laid down and parallel to the ground!
