However it was unable to connect to the 5GHz network until I manually set the bandwidth to 20MHz. When set to auto, the device can see the 5GHz network but doesn't get an IP address when trying to connect to it. I'm running an HP Pavilion Gaming Desktop 790, Windows 10 Pro (10.0.18363 Build 18363), and the driver version is Intel . Whenusing 5 GHz, it is recommended to use at least 40 MHz channel width, as some client devices may not prefer 5 GHz unless it offers a greater channel width than 2.4 GHz. What is 20MHz bandwidth? 20MHz Bandwidth As for today, most of the wifi customers use it for video streaming, and the bandwidth they use is 20MHz with a frequency of 2.4GHz. Apartir de la llegada de WiFi N, en la mayoría de routers de nueva fabricación además de la opción de elegir el número de canal surgió la posibilidad de seleccionar que el ancho de banda utilizado en esa banda de 2,4 GHz fuera de 40 MHz en lugar de los básicos 20 MHz.De esta forma ocupamos dos canales consecutivos en vez de uno y es posible lograr teóricamente duplicar el espectro Soa wifi radio using 20 Mhz centered on Channel 1 will have signal going up to 2422 Mhz, well into Channel 3. A wifi radio centered on Channel 6 (2437 Mhz) will range down to 2426 Mhz, below Channel 4, and as high as 2448 Mhz, past Channel 8. And that assumes only 20 Mhz channel sizes. 40 Mhz is also common in the 2.4 Ghz range. TheWi-Fi Alliance pointed out that the second equation in part shown below adds an important behavior. It essentially says that if either the primary or secondary channel of a 20/40 router or AP is the same as either the primary or secondary channel of a 20/40 neighbor AP or the operating channel of a 20 MHz router or AP, then 40 MHz operation is permitted. bTTE.

which is better bandwidth 20mhz or 40mhz
