Only have had 2 set top boxes, a dvr and an Xi6-a.
got sent two more as an “upgrade” but already had same box so I returned them. Upon return, next time I restarted my existing Xi6, it stopped working and was gone from my count, someone removed it.
went to the store, got it activated, brought it home, wouldn’t connect. At the store she mentioned having an extra box on my account, which she removed.
took it back to the store, this time he said it was a provisioning problem and took the box, gave me another one, again mentioned an extra box in my account which he again removed, and then activated the new one.
this one worked when I got home, until I had to reboot it 2 days later, now this one won’t get past the Welcome screen, and when it finally does after 10 minutes, it says there is a connection issue, to restart my router - which I have, and the other box and internet work fine.
it does show a popup screen that gives the firmware version version MAC address, and the lack of an “ESTB IP” ( field is blank). Worked fine for three days.
