I just got the M001 and I struggled all day to get WiFi working, it did for a little while, very slowly and only when sitting close to the hot spot (I mean, a few feet away). And after a while, it simply... stopped working. Now when trying to connect it says "Unable to scan for networks" and shuts down the WiFi after a few tries. When checking the advanced settings, I notice that the MAC address is anavaiable. Could this mean that it's broken?
