Mylaptop only supports 2.4ghz so I can't use 5ghz with my internet connection. The router bandwidth has always been 20mhz and I'd get around 30-50mbps out of the 100mbps that my internet offers, but a few hours ago I tried switching the bandwidth to 40mhz and the speed went to 85mbps, I did multiple speed tests and got the same result. Aswe covered in my last blog, Band A is 200MHz wide and offer 8 channels at 20MHz or 4 channels at 40MHz. However, Band A breaks down further into 2 bands. These are UNII-1 Lower and UNII-2 Middle. Band A UNII-1 Lower (Channels 36 - 48) This set of 4 channels allows for 4 non overlapping 20MHz channels or 2 non overlapping 40MHz channels. Choosethe right network band for your devices. For consumer Wi-Fi networks, there are three frequency bands: 2.4 GHz, 5 GHz, and 6 GHz. The following is a list of the pros and cons for each. In some cases a 2.4 GHz network will work fine for basic tasks, such as surfing the web or using email. However, faster throughput is generally available TheXiaomi Mi 11 Ultra has two internal antennas, therefore, we can achieve a speed of up to 574Mbps in the 2.4GHz band (WiFi 6, 1024QAM and 40MHz of channel width), and we can achieve a speed of up to 2.402Mbps in the 5GHz band (WiFi 6 in 5GHz, 1024QAM, 160MHz channel width). In the case that we use WiFi routers that only support 80MHz of channel width in 5GHz, we can achieve a speed of up to Vay Tiền Trả Góp Theo Tháng Chỉ Cần Cmnd.

which is better bandwidth 20mhz or 40mhz
