Quick question i hope someone can shed some light on :

1. Unifi tech came to my house after scheduling an appointment to update the firmware on the VDSL unit. I didnt have time to be there when he was doing it but when he finished i asked what the firmware was for and he said its for remote access so that they can troubleshoot remotely. Anyone else knows about this update?

2. Whats the default IP for this VDSL unit?

3. (Longshot question) Anyone knows the default ID/PW?

thanks in advance
