I don't know for WIFI, but I really receive 4 with 5/5 connectivity, and more than 30 in total from my apartment, it's crowded, and that's a bit silly that everyone installs their own box. I don't know exactly where it comes from, but even when it's calm and breathable, I don't feel especially good in my apartment, the difference with outside is incredible, so I'm trying to sleep, eat & work outside. I go back at my appt so recharge batteries, water bottles and food
