Comcast XB3 Modem Keeps Resetting Every Night/Early Morning, Flips Between Two Different IP Addresses
My XFi XB3 modem keeps resetting nightly, between 3-5am. Logging into the modem and checking the event logs shows the same consistent activity between the hours I said.
It seems to try to flip to a different IP address and then back to the original IP address. These IP addresses are the same each time, so I'll be naming them IP 1 and IP 2
Every night the modem will first reset and display
erouter0 got new IP (IP 1)
Then about 5-20 minutes later after the modem has come back online it will reset again and display:
mta0 got new IP (IP 2)
Then, on the most recent night, not even 2 seconds later another log will come up identical to the first one, going back to IP 1
This has happened ever since we went into a local Xfinity store to replace our old XB3 modem with this new one a few months ago, and I hope the problem is not due to that as the internet works fine throughout the rest of the day.
T3 timeouts also happen about once to twice during the day along with logs like:
erouter0 T1 Expired, Enter Renew State
happening about every other day.

Talking with the Xfinity Support team here, I've been suggested to upgrade to the newer XB6 modem, as it will better handle the speeds my plan has. All they have noticed is some power fluctuations which might cause the modem to reboot and lose connection frequently. I'll update this post later this week or next week when we do manage to upgrade to the XB6 modem.
