Expired Certificate/ Untrusted

So I notice AGAIN my service a bit laggy with only 2 connected devices =an Arris TG1682G (rented) gateway and iPhone 12 ( excluding the
Cisco DPC3941T router
Connection type= UPnP
It’s been using my network since 12/21)Fing app and Desktop seem to be able to detect unauthorized connected devices that Xfinity can’t and or won’t on it’s own service. Aside from the freeloading Cisco router contributing to slowing down my network (High speed with only connected devices) I check Network and Internet settings on my PC and discovered 3 IPv6 addresses DNS servers all show as Unencrypted same thing for IPv4 all addresses Unencrypted.. and there shouldn’t be that many addresses associated with my network being ALL public hotspot settings show as “DISABLED”🤷🏽♀️ I just used fing app notice it shows Xfinity Cómodo /my router.io Certifícate is expired! So that may also contribute to one of MANY CONNECTIVITY ISSUES I deal with on a regular (which fall on Xfinity’s workmanship
( or lack thereof ) 99.1% of the time ) Expired Certificates, flagged/ Suspicious/malicious/ fraudulent activities Associated with the many a IP addresses Xfinity allows (although tabs show DISABLED ) anyone with in range to connect with. So do an online search on expired certificates, turns out my rented gateway in Laymen’s terms = the rented gateway expired /obsolete and SHOULD NOT Be operating/have service upon its expiration date. my Model is on the list of invalid devices according to this forum. So why wasn’t I made aware of this it’s their equipment aren’t they in charge of all the updates and what not ? So for over a month now all my data activity has been unencrypted. I want answers please ?

Just installed a new modem from Comcast this week. Cannot connect anything. Expired certificate message same as above. What gives? I use this network to monitor health and well being of 90 year old. Help!
