My new AIO PC, which has a Realtek RTL8822BE wifi card, does not connect to my mesh router Asus Lyra Trio on the 5GHz band. It can only connect to 2.4GHz band. After some research, and the post below, I realised this wifi card supports only a limited number of channels in the 5GHz band. I tested with a spare router - with default settings the What distinguishes Wi-Fi 6E is not necessarily a new standard, but a new band.Previous iterations of Wi-Fi operate on the 2.4 and 5 GHz bands, which have grown more and more congested over time. 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'. The "n" protocol is capable, theoretically, of well over 200 mbs speeds. I say theoretically because speeds and connections are dependent on so many factors. The 2.4 ghz wireless range, which that card works on, is the basic range that the vast majority of wireless systems work on, and that creates interference problems. If you keep the SSIDs different, it means that you can prioritise 5GHz over 2.4GHz by adding both to your Wi-Fi connections, and saying that one is better than the other. Note that 5GHz is not inherently faster than 2.4GHz. They both have the same theoretical maximums, 150 megabits per second (single radio chain), 300 megabits per second (two If the device does not support 5 GHz, consider upgrading to one that does. The 2.4 GHz band is crowded and known for poor connectivity. Minimize the use of wireless meshing between APs when possible. Although it is a convenient way to extend WiFi coverage, it is much more susceptible to high interference and each "wireless hop" results in at Learn more in Wi-Fi 6: What can we expect from 802.11 ax: Wi-Fi 5 / 802.11ac: 5 GHz: This designation does not distinguish between the first ax products and the latest round that includes newer technologies, known as Wave 2. Wi-Fi 4 / 802.11n: 5 GHz and 2.4 GHz Traditionally Wi-Fi operates in 2.4GHz and 5GHz spectrum. But now with Wi-Fi 6E, there is an additional frequency spectrum made available to devices that support Wi-Fi 6E. a. Devices that are newer are capable of Wi-Fi 6E can now operate on an interference-free band to potentially gain higher throughput with lower latency and interference. .
