Hmm, I'm in a 60-apartments block and we don't have this problem at all. Heck, even my shitty Meross devices manage despite all the 2.4 and 2.4+5 GHz connections around. What I struggle with is reliable 4G, and even 5G is so shabby I might as well keep it disabled. More spectrum for network signal sounds like it would help much more than improving Wi-Fi, which is already very reliable and plenty fast. My 2 cents…
