Wi-Fi signal strength is typically measured in decibels per milliwatt (dBm). A higher dBm value indicates a stronger signal. The ideal Wi-Fi signal strength for a stable connection is between -50 and -70 dBm.
-90 dBm is a relatively weak signal strength. A signal at this level is typically considered marginal or poor. It may be adequate for basic internet activities like web browsing or email, but it is not suitable for high-bandwidth applications like streaming or gaming.
No, -90 dBm is not considered a normal Wi-Fi signal strength. According to a study by the Wi-Fi Alliance, a nonprofit organization that certifies Wi-Fi devices, the average Wi-Fi signal strength is around -67 dBm.
Weak Wi-Fi signal strength can cause:
Here are some effective strategies for improving Wi-Fi signal strength:
Story 1:
John had a weak Wi-Fi signal in his bedroom. He tried moving closer to the router, but it didn't help. Then he realized that his fish tank was between the router and his bedroom. When he moved the fish tank, his Wi-Fi signal improved significantly.
Lesson: Obstacles can significantly weaken Wi-Fi signals.
Story 2:
Mary was having trouble with her Wi-Fi connection in her living room. She called her internet service provider (ISP), and the technician told her that her signal strength was at -95 dBm. The technician suggested that she move her router to a more central location in her house. When she did, her signal strength improved to -70 dBm, and her Wi-Fi connection became much more stable.
Lesson: The location of your router can have a major impact on signal strength.
Story 3:
David had a Wi-Fi signal that was strong in some parts of his house but weak in others. He purchased a Wi-Fi extender and placed it in the area with the weak signal. The extender boosted the signal strength in that area, and David now has a strong Wi-Fi connection throughout his entire house.
Lesson: Wi-Fi extenders can be an effective solution for improving signal strength in areas with weak coverage.
A strong Wi-Fi signal is essential for a reliable and enjoyable internet experience. Weak signal strength can lead to slow speeds, dropped connections, and other problems that can be frustrating and inconvenient.
-90 dBm is not considered a normal Wi-Fi signal strength. Weak Wi-Fi signal strength can be caused by various factors, including distance from the router, obstacles, and interference. By understanding the causes of weak signal strength and implementing effective strategies for improvement, you can enjoy a strong and reliable Wi-Fi connection throughout your home or office.
Table 1: Ideal Wi-Fi Signal Strength
Signal Strength | Quality |
---|---|
-50 to -70 dBm | Excellent |
-70 to -90 dBm | Good |
-90 to -110 dBm | Fair |
Below -110 dBm | Poor |
Table 2: Causes of Weak Wi-Fi Signal Strength
Cause | Description |
---|---|
Distance from the router | The farther you are from the router, the weaker the signal will be. |
Obstacles | Walls, furniture, and other objects can block or weaken Wi-Fi signals. |
Interference | Other wireless devices, such as microwaves and cordless phones, can interfere with Wi-Fi signals. |
Table 3: Strategies for Improving Wi-Fi Signal Strength
Strategy | Description |
---|---|
Move closer to the router | The closer you are to the router, the stronger the signal will be. |
Reduce obstacles | Remove or reposition objects that may be blocking the Wi-Fi signal. |
Minimize interference | Move other wireless devices away from the router. |
Use a Wi-Fi extender | A Wi-Fi extender can boost the signal in areas where the signal is weak. |
Upgrade your router | A newer router may have better signal strength and range. |
