There are only 13 20MHz channels in 2.4GHz, which quickly become congested due to many devices that, in turn, generate interferences. Thus, it's practically impossible to connect to 40MHz channels in that frequency band. In theory, 40Mhz has twice the channel bandwidth compared to 20Mhz, and the theoretical data transmission rate is also twice as high; However, from a practical application perspective, setting a higher bandwidth has a greater chance of conflicting with surrounding WiFi signals, which can affect the actual data transmission rate. Assalamualaikum friends@LifeWithAamir In this video discuss about 2.4ghz wireless channel width, who's best in 20mhz or 40mhz ?@LifeWithAamir For more videos 20Mhz. -----. 20MHz is the most common Wi-Fi bandwidth as most users still opt to use 2.4GHz radios. 40Mhz. -----. In an environment with less congestion where a higher data throughput is required, using the 40MHz channel can be a good idea as it still offers 12 non-overlapping channels on 5GHz. 80Mhz. -----. WiFi 20 MHz atau 40 MHz: bagaimana memilih bandwidth. Beli a router Wi-Fi baru kita akan sering menemukan kata-kata « 300 Mbps «, Kecepatan yang diperoleh dengan koneksi WiFi pada frekuensi 2,4 GHz. Guys you can view my previous speed tests on 20MHz bandwidth here:-1) https://youtu.be/NfJIW_UQkKU kH74fLo.
