I connected to my Hub 4 with VM Connect, measured WiFi speed, and ordered a Wi-Fi pod. Then my Hub 4 went down a few times during the next few days, and one day it failed completely. I did the factory reset, but then the web interface didn't work and neither VM Connect nor Wifi pod that just arrived couldn't connect to it, also Wifi was going down every 5 minutes. I did another factory reset, but that didn't help, however, web interface is up if connected straight after reboot, then it goes down again.
Here are the broadband monitors (from the latest to the most recent one):
