Question Archer AX1500 or Archer C80 AC1900

Unless you have wifi6 devices I would buy the ac1900 and wait. Wifi6 is outdated tech and wifi6e is just starting to become more common.

Even if you want wifi6 that is a very poor choice. Most wifi6 end devices only support 80mhz channels so they can't use that routers ability to use 160mhz channels. It is also a single stream no mimo. So this is pretty much the same as buying a 802.11ac router with a number of 600.

You likely are going to get faster connection to the older 802.11ac 1900.

It all depends on your end devices.
