Sebagian besar perangkat Wi-Fi yang lebih lama hanya mendukung 20MHz, sedangkan perangkat Wi-Fi yang lebih baru mendukung kedua channel bandwidth. Jadi, jika Anda memiliki perangkat Wi-Fi yang lebih lama dan ingin menggunakan 40MHz, maka Anda perlu memastikan bahwa perangkat Wi-Fi Anda mendukung 40MHz. Perbedaan Konsumsi Daya In most populated areas you shouldn't set 2.4ghz higher than 20mhz. You shouldn't use channels that overlap. In the US in most cases you only want channel 1,6 or 11. 例如頻道6通常是2.437GHz頻帶，在20MHz頻寬下，使用範圍從2.427GHz到2.447GHz，不會干擾頻道1及頻道11；但若改為40MHz頻寬，就會使用2.417~2.457頻帶，進而影響頻道1及頻道11的傳輸品質，更不用論在2.4GHz中，還有像藍牙、無線電話等其他干擾因素。 For 2.4Ghz stick to 20MHz channels on 1,6,11 only. If you're in a country that allows above 11 you may have more options but channel 2/4 will overlap and cause more interference. Generally it's recommended not to use auto channel selection. For 5GHz, use wider channels and use that for higher bandwidth applications/devices. Yes you should leave it at 20MHz on 2.4Ghz otherwise you are just reducing the already limited non-overlapping channels within that frequency band. If you set it for 40, it will fall back to 20 during noisy operation. If you're going to use 2.4 already, which is really really bad compared to 5 GHz, then go wild. so the WLC can dynamically chose the 20MHz channel or select 2x20MHz channels to form a 40MHz channel set. clients are assigned 20 or 40 MHz channel on request. so most likely on the AP's involved there are NO clients that are 40MHz capable or have requested 40MHz bandwith. By the way. 802.11ac allows per-frame channel width and bandwidth 2015-Apr-26 8:58 pm. If you're in a crowded environment, select 20 MHz for 2.4 GHz. It's unlikely that 5 GHz is as crowded, so feel free to use 40 MHz there. Upper or lower sideband just tells the Apple to this day locks out 40 MHz bandwidth mode in 2.4 GHz entirely on its AirPort Extreme and other 802.11n routers and combo devices. Intel initially followed suit with its 802.11n Centrino wireless adapters, but has since relented. Intel adapters now allow 40 MHz mode in 2.4 GHz to be set, but ship default set to 20 MHz only mode.
