Geolocation wildly different all of a sudden

I've had xfinity for over 10 years. In that time, I've never had a problem with my IP geolocation being so wildly different than my actual location, usually about 2 miles. Now, a week ago, my IP address has all of a sudden shown me in a different state. It has caused massive problems logging into banks, email, and security apps when connected to my wifi. When I use my cell, which is Verizon, it shows my geo location just fine. After 9 hours of talking to zombies and robots in tech support literally spouting FAQs and what not, all I'm told is it's my hardware problem since I have my own modem. Funny thing about that, other than no settings have been changed since I've owned it, and I never had the problem before, is if I connect to the neighborhood xfinitywifi hotspot it shows the same problem, a completely different state for the geo location, confirmed by 10 different ip location services including Maxmind. Now, correct me if I'm wrong - if it were my equipment and only my equipment, why would the hotspot that is broadcast by my neighbors show the same problem? Why would 2 of my neighbors I spoke to who have Xfinity hardware been having the same problem? Oh, but yeah, it's my hardware that is the problem according the the bots in tech support. Digging very deep into this, Xfinity is one of the only companies that DOESN'T update location data when they rotate IP blocks, and you can end up with an IP address from way far away with no recourse but to try and fix it yourself by reporting location errors to the location data reporting sites. It's madness. When I asked the bot to run the xfinitywifi hotspot IP address she confirmed that it was indeed in another state, but then still told me it was my own modem hardware that was the problem. Literally, this trashiest of the trash companies, refusing to admit their own mistakes and fixing the problem. Oh, and they lied 3 times to me that there was no higher tech support and then after an hour 1/2 each time going through the motions of "resetting" my hardware, they finally said ok, lets escalate this to the next level. And finally they just hung up on me after refusing to admit they either a) don't know what they are talking about or b) they were lying and knew exactly what the problem was but refused to admit it.

Lies, cheating, and trash company policies. That is Xfinity. They better watch out, Ting and Starry are spreading like wildfire.
