I have 5 Oaks. For the first 4, the update went smoothly once i switched to using the local update server, although in every case i had to manually claim them in the particle cloud. For the 5th, it simply won't connect to the wifi network, although apparently the wifi scan works ok (the setup wizard shows the list of SSID), and the other oaks had no trouble connecting with the same SSID and password. Any ideas?
