Wifi 7 can combine 2.4Ghz 5 Ghz and 6 Ghz bandwidth. So range will not be a problem. Speed will drastically reduce as your device will be using 2.4 Ghz frequency the further you move away from your router. Wifi 7 also has beamforming and Mu-mimo improvements to give better range. If you set up your router to beam 3 different Wifi networks on 3 frequencies and you connect your 6e/7 devices only to 6Ghz network, then ofcourse you will have range issues.
Range? I think most people should, if anything, dial back their power.
Go stand on the edge of your property and lower the power until you can’t connect
