i don't think the wifi 6e is the deal breaker, if anything, wifi 7 is already out so the whole wifi 6e is already outdated, plus the denser the radiowave transmission, the less walls it penetrates, therefore to achieve max bandwidth, you have to have little to zero obstruction between the laptop and the router.
the real question you should be asking is how long of battery life you want, both m1 and m2 will have significant better battery than your current, but the m2 pro's more efficiency core means you can get couple more hours than m1 pro
