Wi-Fi 7 to get the final seal of approval early next year, new standard is up to 4.8 times faster than Wi-Fi 6::There are a lot of ‘draft’ Wi-Fi 7 devices around, but ‘Wi-Fi 7 Certified’ devices will only come to market sometime next year.
You wont want to disable 2.4 and 5GHz on wifi 7. The reason it gets so much higher speeds than 6e is that it can send data on all 3 spectrum simultaneously. If you turn off 2.4 and 5GHz you would essentially be limiting yourself to 1/2 speed.
Are the 320mhz wide channels going to be actually usable in the real world though? wider channels increase chance of interference. That’s why nearly everyone recommends 80mhz wide channels on 5ghz even though 160mhz channels have been available for a while. You dont usually see speed increases in the real world with the 160mhz channels except in specific situations.
