1. For internet purposes 7 would only be useful if you have much greater than gigabit internet speeds. I get 1.4 gb 6E speeds with 6E which is limited by my internet modem bandwidth.
2. Wifi 7 routers do exist but are quite expensive. Of the 4 listed on Best buy 2 are over $1K, the cheapest is $600. It may be years before prices become reasonable.
3. Apple is only now slowly running out 6E to its devices. Wifi 7 is years out.
4. WiFi 6 is more than most people need as I assume that relatively small proportion of internet users have speeds > 1 Gbs.
Didn't know that Wifi 7 routers were now available. Thanks.
One thing I have noticed with my M2 MBP - the WiFi 6E gets me almost as close to my max speeds (I have a 2Gbps plan) as ethernet does, even though my router is only a WiFi 6. I am considering upgrading it to a 6E model though, especially now that I'm almost done building my media server.
