That is, use the same WiFi name and password for your 2.4 GHz, 5 GHz and 6GHz (if applicable) bands, so you can take advantage of this seamless connection to the best network. Some Background: Understanding the 2.4 GHz, 5 GHz and 6 GHz Bands. The 2.4 GHz band offers better WiFi coverage, but is prone to more congestion due to heavy network traffic. Wi-Fi 6 means 802.11ax technology - the new generation of Wi-Fi, present in many routers you can buy today. Wi-Fi 5 means 802.11ac technology - effectively the previous generation. Wi-Fi 4 means Sun Jan 12, 2020 1:09 pm. Hello. Recently I bought RPi4 and put sd card from my old RPi3. The problem is that it doesn't want to see 5GHz Wifi at all. $ iw phy phy0 channels. Code: Select all. Band 1: * 2412 MHz [1] Maximum TX power: 20.0 dBm Channel widths: 20MHz * 2417 MHz [2] Maximum TX power: 20.0 dBm Channel widths: 20MHz * 2422 MHz [3 Set to All (preferred), or Wi-Fi 2 through Wi-Fi 6 or later. Radio mode settings, available separately for 2.4GHz, 5GHz, and 6GHz bands, control which versions of the Wi-Fi standard the router uses for wireless communication. Newer versions offer better performance and support more devices concurrently. When enabled the router uses the same SSID for both 5ghz and 2.4ghz and likely steers 5ghz wifi capable devices towards the 5ghz signal only. So try turning band steering off. Afterwards should also change the SSID of the 2.4ghz band to something different from the 5ghz band to make it is easier to differentiate. ShiftyPan.

Wi-Fi 4 / 802.11n: 5 GHz and 2.4 GHz Moreover, 5GHz can support 1Gbps. This is a huge difference between 2.4 GHz and 5 GHz WiFi, which shows that 5GHz is more speedy than 2.4GHZ. Even though it is faster, 5GHz is not used as frequently as 2.4GHz. It is because the 2.4GHz covers longer ranges and bigger areas, as well as transmitting through solid objects like walls. Make sure that your device is 5 GHz WiFi capable. While most modern WiFi devices can connect to the 5 GHz band, some devices might only support 2.4 GHz connections because they have very low bandwidth needs or were manufactured to meet a low price point. Some IoT devices and WiFi-capable printers, for example, only connect to the 2.4 GHz band. When I'm connected to 5ghz only networks it is mostly OK, but when 2.4 is available, even when I'm close to the router, it causes all sorts of issues and tries to bounce between the two. This phone is so garbage. Wifi issues since day one and I know Samsung nz will try and scam me out of money if I send it on for 'repairs'. There's only 3 non-overlapping WiFi channels and tons of things also run on 2.4GHz, such as bluetooth, wireless mice, cordless phones, and when you turn your microwave oven on that emits 2.4GHz interference. 5GHz is a lot less crowded, but just travels less far. 1 more reply. zO52Uow.
