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 ?

This is just a sample of some of the issues this access point  my PC while connected via Ethernet it’s like the gateway triggers my pc to act as a modem even though my pc is configured not to. My service is mishandled/low quality support as to my demographics as to the many requests ignored to get a tech out to secure the outside terminal it’s unlocked always being tampered with the top is always off. Demographics play a big part in what quality level of  service customers receive. All Money/ plans  may be the same however level of quality will not at least in the city I live in .  . Please note my devices are highlighted in yellow.

Same problem router is XB3 and outlook continues to report invalid Comcast certificate. Ethernet set to use DHCP Ip address and DNS set automatically. I did see  a certificate popup on my iPad and if I recall it said Comcast certificate expired 2005 (: Thanks Mary

Thank you for letting us know you are also experiencing this issue, @Reghir. Are you noticing any issues with your service aside from the certificate? Our XB3 modem is still in use. I checked on your internet speed tier and that is still the recommended model for it.

We can get the modem upgraded for you, @Reghir. Just because it is the recommended model doesn't mean we can't change it out. With the certificate problem and having to reboot the modem so often let's take action to see if that resolves the problem.
