Cannot login to app using known working credentials that work on the website. This is absolutely infuriating, I am trying to troubleshoot your terrible system that has massive latency spikes all the way up to 1000ms and it's causing so many issues for me. I'm trying to modify QoS settings, but your stupid ONT says to access this setting on the app, and then I get the app and I literally can't even log into it at all using known good credentials to change this settings. BS.

This app is completely USELESS! I can't use the app for anything besides making a payment and changing the account password. The app can't do any of the things that Quantum claims, real time updates, manage devices, customize the network, and the shared QR codes for ease of access over multiple devices. Absolutely shameful to lie to people to get them to download your AWFUL USELESS app.

This is as far the worst service I have experienced. Don't bother wasting your money with Quantum. You will maybe get 2 hours of WiFi if you're lucky. Seems like I only get the 2 hrs in the middle of the night. I have called multiple times, 3 technicians came to look at the modem that's all. It's ridiculous no one can figure out what's wrong. I get a different stories every time I call. They don't even deserve 1 star. Just the worst.
