I've been doing some reading on the 160nhz band for wifi 6. Am I right to say that for the next 1 to 2 years at least there will not be much practical real world difference in speeds between a wifi 6 router that supports 160mhz vs one that doesn't? Assuming all other specs like ram and cpu are identical.
It depends on your devices. But I will go with a Wifi 6 router which supports 160MHz now.
Personally I see major differences already now.
Main router: Asus RT-AX82U (4 * 4 AX/AC with 160MHz support on the 5GHz band).
My computers:
1) 2017 Acer laptop with upgraded Intel AX200 based no brand adapter: support 2*2 AX 160MHz on the 5GHz band (800-900Mbps)
2) 2019 Dell laptop with Intel AC9560 Adapter: AC adapter with support of 160MHz on the 5GHz band (not AX), very big differences between 80MHz and 160 MHz (reach 900Mbps+, faster than the Acer)
3) Mac Mini M1: 2*2 AX with 80MHz support, wireless speed is a bit worse than the above two (600Mbps+).
I also use the Huawei AX3 Pro (2*2 160MHz support) as the wireless media bridge and it gets very good speed as well for the LAN clients.
I do not have LAN ports in the rooms but with the RT-AX82U I do not have the need to wired the home as of now. Of course LAN ports will be better, but so far so good.
