That is disappointing not to have 7. I recently upgraded my WiFi 6e system to WiFi 7 when Amazon had its last Prime Day. I picked up TP-Link routers for 53% off. WiFi 7 is a major improvement over WiFi 6e even if a device doesn’t support 7. On my previous system, my iPad with 6e would get about 400Mbps over the Internet (I have a 1.2Gbps plan). With 7, that same iPad gets a tiny bit over 1Gbps. The range is also improved with the far corners of the house getting improved reception. We have only one WiFi 7 device on the network, which gets 1.4Gbps Internet speed, the same I get for wired Ethernet. As an aside, my max speed is supposed to be 1.2Gbps, but I guess I’ll take 1.4Gbps.
I don’t have anything to test internal network speed, though I do have a 2.5Gbps network. I’m guessing a WiFi 7 device would be able to reach that fairly easily since YouTubers report getting 7-9Gbps internally with their devices.
Fortunately, I don’t plan to upgrade so it won’t matter. I already have an M3 Max machine and an M4 Max just wouldn’t be worth the expense.
