2.4 GHz network performance
2.4 GHz network performance
In our home we possess one modem and one access point which provides excellent coverage; however, the Wi-Fi speeds remain quite low. The 5GHz network functions as expected, but the 2.4GHz band is significantly slower in certain areas, especially in the living room where it’s about three meters from the modem. There’s a wall blocking the signal, resulting in speeds around 4 Mb/s. I’ve separated the 5GHz and 2.4GHz networks for troubleshooting. The most surprising issue is that both access points fail to connect in this section, suggesting interference. My modem model is a Zyxel DX3101 with an AP from Mercusys AC12. I’m puzzled as to what could be causing the slowdown. There are several wireless devices around—an old Samsung smart TV, a laptop, four phones, five smartwatches, a tablet, and a home security system operating at 500Mhz. A few Bluetooth headphones are mostly off. Despite trying to figure it out, I still don’t understand why the connection is so poor.
2.4GHz is highly prone to interference from nearby devices operating on the same frequency. Perform a wireless channel analysis using software such as WiFiman and examine the visual spectrum display. This helps identify suitable channels for your broadcast.
