The last is effectively 40Mhz with fallback to spec, more on that soon. A speed setting. Some brands use 150mbps / 300 / 450 to infer what bandwidth is being chosen. 150Mbps is the safe 1 20mhz bandwidth setting. The underlying issue is 40Mhz bandwidth is actually 2 adjoining full width wireless channels (ie 1 & 6) being used together to I have my Orbi Router set to only use 20MHz Width on the 2.4GHz band (channel 1). However, using WiFi Scanner, it shows my Orbi wireless connection is using a 40MHz Width. I would like to only use the 20MHz Width on the 2.4GHz band (to "play nice" with my neighbors, and minimize poor connections due Reducing to 20 MHz will allow you to utilize a larger number of channels and you won't have APs utilizing the same channel. You can utilize 40 MHz Channels with 9 APs utilizing every single 40 MHz channel, in an auditorium for example. The problem here is if some sort of interference or a rogue AP is introduced to your environment. It's just bandwidth - how much data can be carried at once. Think about a cargo van and a semi truck both going the same speed down the highway. You generally want to go with 40 MHz channels for client serving in most cases. Wider channels generally work best for wireless bridge applications in areas with very few potential interfering The 5GHz band is divided into 5MHz channels like the 2.4GHz band. Fortunately only every fourth channel (36, 40, 44…) is used which provides for de facto 20MHz channel width without the overlap problems of 2.4GHz. Most devices even cannot be tuned to the intermediate channels. The whole 5-6GHz is not available since there are some forbidden Dịch Vụ Hỗ Trợ Vay Tiền Nhanh 1s.
