My ISP has taken total control of my network - Lemmy.one

This is very troubling, and I’m not even sure where to start. I recently received an email message from my ISP which alerted me to an incoming update. I didn’t worry too much since this is obviously not the first update they’ve ever pushed through. However, after this update, I noticed that my guest connections and some other things had changed / disappeared. I logged on to my router, and I immediately noticed my custom password had been reset to the default. No problem, I entered it. At this point, I saw that all of my options were greyed out. I could change the password, which I did, but nothing else. I immediately called my ISP. I was told that I would have to use their app now, so as much as I dislike using proprietary phone apps, I conceded and installed the app through the Play store. However, the agent was not entirely honest with me. I still can’t bifurcate my 2.4g and 5g connections, nor can I add or remove any guest connections. I immediately enabled “privacy mode” via the app, which purportedly prevents information from being collected by something called “HomePass,” and I “Delete[d] Guard events” whatever the hell that means, but this seems really troubling. I can no longer access my modem/router settings via the normal interface, but have to use an Android app? There is only one other ISP in my area. They have much worse/slower service, but should I switch, or is this just the “new normal”? Does what I’m describing even make sense? I’m not a tech expert, but I feel like I’ve self-taught myself how to navigate these settings, and learned from others in online forums, but now … an Android app? I’d appreciate any advice. I’d even be willing to purchase my own modem/router instead of using the one from my ISP, if that fixes this mess.
