PS5 Connection Error and Poor Customer Service

I've been trying to fix this for months now at this point and it seems like Xfinity tries to blame it on my PS5 100% of the time, but every time I turn on my PS5 from rest mode, my XB8 and the onboard software flag it as "IP Reputations" threat and blocks my PlayStation from accessing all its features like friends list, and store because the modem looks at it as a security threat. I know I've seen many posts about this, but I haven't found an answer that works. 

I talked on the chat feature for an hour with a rep and they told me to trade in the XB8 at the store for an XB10 which would fix the problem, and they would put notes in my account. I then showed up at the store for an appointment I setup and clearly put in the notes "trading in XB8 for XB10", clearly nobody looked at that ahead of time because I was told that the XB10 won't work at my address. Then I go on that chat feature again a few hours later, and a new agent tells me an XB10 would in fact work at my address. I've repeatedly been given bad and differing information from multiple representatives. They keep rescheduling technician appointments, and I've come to the conclusion that they won't be able to provide the support I need to get this fixed as it will just get passed on to a "supervisor" or, the tell me the issue is responsibility of some other department. 

The website tells me to go to the security tab at the bottom of my Xfinity app and select security to allow access for 30 days at a time but there is no security tab (I've seen other posts that this is another common issue), but it's still the most "up to date" fix in their support documentation. 

My PlayStation is hardwired and I've verified the cable itself functions properly by running speed tests on 3 different computers/laptops with the same cord. I cannot find a reason why my PlayStation trying to connect to the internet to access my friends, game store and use my text/party chat function would flag as a malicious IP threat. 

Nobody seems to be the right person to chat with and at this point I've started looking into other home internet options purely based off customer service reviews to make sure that even if there is an issue, someone will care about helping me solve my issue.
