Getting Xfinity to connect a XG1v4 Coax based box = Impossible

Xfinity services themselves are decent, a bit expensive, but offer decent quality and reliability.
However, their Customer Service and Computer systems are a joke, and it amazes me that Comcast (CMCSA) is a profitable company at all.

I’m about to join the ranks of TV Cable Cutters, and switch to something different.
It all started when I was logged onto my Xfinity account and there was a message saying I was eligible for an Upgraded TV Box.  My older box was a Coax connected, XG2v2-P. 
Done, I accepted.

What I received, via mail, was an XiOne-SC(B) box, which is Wireless and designed to be a Satellite box, not a primary box. NOTE: I have only one TV connected to Xfinity, and own my Modem and Router. So, the XiOne-SC(B) wasn’t suitable for my situation.

I then went to my local Xfinity store and Exchanged the XiOne-SC(B) box and was given a Xi6-A box; also Wireless. Using the Xi6-A, I’m not happy, as it has a few issues --
                It times out after four hours (sleep timer is off)… I like to leave on for my pets, noise in the house
                It freezes occasionally.

So, researching Xfinity, it appears the XG1v4 is available, active in the Xfinity universe, and is Coax based.  I wanted this box. Returning to the Xfinity Store, wanting to exchange the Xi6-A for a XG1v4 (Coax). It took thirty minutes at the store, as they were unable to add it to my account. Said Xfinity was moving away from Coax based boxes, towards Wireless boxes…  Yet I left with the XG1v4, and kept the Xi6-A box too.

Hooking up the XG1v4, then chatting with Xfinity, they did tell me it would not work, offered to send me the correct box. Coax? Agent couldn’t tell me… a day later, another XiOne-SC(B) arrived.

I now have:
1. XiOne-SC(B), Wireless, not using -- Returning
2. XG1v4, Coax, won’t connect -- Returning
3. Xi6-A, Wireless, connected, working… sort of

Today, 9/17/2026 I hooked up the XG1v4 again and called customer service to see if they might be able to get it to work. After many back and forth questions, verifying Serial numbers, MAC addresses ,etc., 50 minutes later the agent tells me to go to the Store and have them help! It's not happening, as the store was already unable to help, and told me the XG1v4 wouldn’t work. Either Xfinity is phasing out the Coax based boxes, or their computer system is frustratingly slow and preventing any updates?  

Two trips to the store, two calls into Xfinity customer service and I’m back to the Wireless Xi6-A. I'm Not a happy Xfinity customer… 32 years thus far.

For now I’m stuck with the Wireless Xi6-A that freezes and times out. I'll see how it goes, but if it continues to Time Out, Freeze, etc.... ??
