Just terrible

Terrible

Bad service def avoid

Omg switching to quantum was a terrible idea. 1 gig but the network is so unstable I can barely load a website sometimes.

Meh

App is ok but customer service is terrible and rude. No help whatsoever and I’m not even sure they grasp what I am even talking about with my concern/complaint. Like talking in circles.

App does not work

This app does not work. It doesn’t detect routers. It doesn’t give you network information or anything. I’ve literally sat there with my screen on for 15 minutes waiting for the app to finish loading one of the tabs and it never did. If I could give it 0 stars I would.

Wrapper for the website

This app is about as useful as the Quantum website, which is to say "not very." What's worse, it's tied directly to the website - if the website is down for maintenance, the app displays a message saying so. This means while they're performing maintenance you lose access to the very tools they tout as the reason for installing the app - no wifi maintenance, restarting router, etc. And it requires me to log in every single time I open it, but the keyboard doesn't support password managers so it's a real drag. Make a real app or improve your website - preferably both!

Terrible Provider and App

To begin simple, the app either does not work, does not load, or sends you to the website with frankly unhelpful troubleshooting information. That’s where the issues with the app end and the issues with the provider in general begins.
I moved into a complex recently with a pre-installed router and modem. I went through all the steps to turn on the internet and nothing. I reach out.
1. When signing up, I stated to schedule a technician to arrive for install, which was weird because it was already in unit. I work so I had to wait until the weekend. Once scheduled, my portal said it would be a self-install process, and despite already having the equipment, the internet would not work until the weekend.
2. Internet didn’t work anyway, so I tried reaching out for assistance and the ai bots were never helpful and always had to redirect me to an agent after misinterpreting my messages and repeating unnecessary information.
3. The agents set me up with a technician to come over and assist the following day. I scheduled 4-8pm as I work and would be unable to be home before hand. I was told via confirmation message to include instructions for the tech when they arrived, which I did in regard to getting into the complex. Day of the appointment, I get a message that they are early and were going to come over early and that if I wasn’t available they’d come back at the original appointment time. I wasn’t home, I was at work. There was no attempt to contact me other than receiving an appointment CANCELLATION message. It stated I was not present, and that they were unable to get into my complex. Mind you, they arrived 3-4 hours before the appointment, and they refused to send the tech back at 4pm saying they couldn’t. They rescheduled me for two days later same time, ensuring me they left a note and instructions. EXACTLY SAME ISSUE. The tech did call twice, but I am unable to take calls during the work day. They blamed me for all of their issues when I provided instructions to enter, and scheduled a specific time to avoid any issues.
4. The tip of the hat is they offered a $100 gift card insensitive to stay with them twice due to all of their inconveniences. The first time, I accepted, they refused saying I couldn’t have it since I agreed to reschedule and that my issues would be resolved. The second time the refused again because I finally cancelled.
I went one week without internet because of misinformation from their site.
I went another due to poor professionalism.
I work all day, and often have to work at night to prepare for the morning. This company lacks accountability, professional, empathy, and any form of quality service. Frankly, look somewhere else.

Wow

Genuinely the worst app from a service I’ve ever used, the service is also continuously spotty, an overall terrible company. They outsource all of the customer service to India, so they’re literally just there to give yes or no answers.

Promise much, deliver not so much

This app shows many features. But most of them fail to deliver any useful information. Basically they do not work. Yes it tells you account info and your billing history. This app needs improvement.

App not very helpful

I’m so tired of virtual assistants that are no assistance at all for a WiFi network that constantly goes out.

No service X 2

Second day service went down with out an outage

Mr

Guy was great and efficient

Slow and the parental controls not working right

The app is extremely slow to load or save changes.
The parental controls are limited and typically impact all devices on the WiFi. Ethernet plugins are fine but the controls impact devices even if they aren’t selected in the list of devices for a parent control. For example, I block my kid’s laptop at 8pm but then my cell phone is also blocked from the WiFi.

Xfinity was better

I transferred from Xfinity to quantum because I thought it would be better but the Internet connection is worse and the app is always down. I hate using this app. I’m thinking of ending my quantum and going back to Xfinity.

The worst company

I signed up for quantum after I got rid of Xfinity because xfinity is one of the worst companies in existence. Sadly, quantum is just as bad if not worse. The reliability and speed is much much worse and their customer service is just as bad. Since the day I got the service, it has been slow and very unreliable. Even after replacing the modem it is still slow and unreliable. Just making a service appointment took hours of waiting on the phone and then trying to deal with their inept chats. The second time I had a service appointment the technician never showed up and the people whom I was dealing with on the chats were not helping me at all. One representative even disconnected himself from me instead of just telling me why the technician never showed up. I talked to three different people on chat and not one could give me a straight answer on why the technician hadn’t showed up. I definitely do not recommend this terrible terrible company.

Non functional

You can pay your bill only, none of the other options work at all

Horrible!

Cannot login to the app to manage the router at all. I’m using the exact same email and password that does work on the website. Does not work. It immediately locks me out on one attempt. I did password reset everything. Completely worthless! I cannot wait for the other fiber providers to turn on my street to be rid of this horrid incompetent company

Horrible customer service

I was lied. I hate liars. I was given a false name. I was lied to about every single thing !!!!! I’m so upset !

App is ok; Quantum isn’t

After less than a month, our brand new modem stopped connecting to the internet. However, the lights continued to flash showing that it was working. That led me to spend hours fiddling with the routers. An hour on the phone with quantum customer support was utterly fruitless. Technician visit was scheduled for the next day; somehow he couldn’t manage to make the four hour window. Perhaps he will be here soon. I don’t have any idea because they don’t let you know, even though I’ve been waiting five hours so far.
It is hard to believe anyone could make Comcast look good, but Quantum is trying!!!

Constantly drops my WiFi connection

Constantly drops my WiFi connection and I have to reset my router at least three times a month. Every time I pay my bill I all of a sudden have no WiFi for several days. So frustrating!!!!

App is completely useless

App almost never works. Will always show devices as offline even though network is working fine. Never worked since I’ve had service which is a year now. Don’t even bother downloading the app
