Quantum Fiber: The company with such poor tech support they made me go back to Xfinity.

I'm almost done ragging on them. It's hard not to when I've encountered no less than a hundred dns website errors. GJ QF AT&T. I'm not sure how you do it, but you manage to keep some people subscribed to your service. Hey ya know I wish I had that AOL forgotten subscribers money.

Bad DNS server

I've been having bad delays loading web pages in the last couple of days. Tracked it down to one of the two DNS servers being given to me by Quantum.

If this is happening to you, check if 205.171.2.65 is one of your DNS resolution servers, and remove it. Solves the problem. (Google's 8.8.8.8 server is always a good alternative)

I tried reporting this to Quantum support, but that was a waste of time.

(SW WA) How Delicate is Q1000K with W1700K?

I moved to a new apartment last week and this is my first time with these QF devices and in the last week I have had 2 different technicians come to reestablish the connection after the power has gone out briefly and after we accidentally tugged on the W1700K cable.

I am a remote worker and honestly am worried if I need to change ISPs or what. I have a scheduled now a third appointment to get this fixed and I am running out of options.

Does anyone know any tips or general help on how to minimize these type of issues so often? I have also placed an order for a TP-Link Archer BE6500 Dual Band Wi-Fi 7 Router in hopes to fix this but I am worried that will just cause more time without wifi

My zip code is 98684.

Customer service is NOT a priority. Ready to find a new provider after this.

Last Saturday I get a notification, "sorry to let you know there is a service outage in your area" etc. Sunday it's reported fixed, but when I get home Sunday the internet is still down. So I check their fun online "Outage Map". Great News! No Outage in your area! Well that would be great news if myself and five of my neighbors weren't also down.

So, I do the dance with their intl call center who says they can get a tech out Wednesday... UGG, fine. Monday morning I see a QF truck at one of my neighbors houses so I run out there and talk to the tech, turns out the issue was never fixed properly on Saturday and it was a problem with one of their lines, not my equipment. The nice guy says we're working on it and it should be back this afternoon. Monday afternoon the internet comes back, I get a call and the nice QF rep says we'd like to cancel your appt since this was on their end and the service is back up. "Great, thanks"...

1 hour later the internet is down again but since I cancelled my appt no one can come check it out until this Sunday. Oh, and again, there is no outage reported in your area. Of course, all the same neighbors are also down.

I've been trying to explain the QF techs confirmed there was an issue in the neighborhood but the polite call reps keep telling me I'm wrong. Of course they can't even ping my router but I get it, their just call reps and no specialists can take a look for 4 more days because this is only happening to me. To which I said fine, Don't come to my house, just come check out the line in the neighborhood that was the initial problem. "Sorry we can't do this as the issue is only affecting your service and we've had no other reports." I can confirm at least 4 other reports and the QF worker on Monday confirmed even more.

This is terrible customer service and if I can find another provider to come before Sunday I'm going to leave their equipment on the curb and tell them to come pick it up on Sunday.

DO BETTER OR LOSE BUSINESS... It's pretty simple.

Boulder Quantum Fiber Customer Service is TERRIBLE

Tried to get Quantum Fiber (AT&T) here in Boulder. Scheduling the install took 2 weeks then on the day they were to install it, they cancelled my appointment (8-10am window). I was able to get an appointment the same day (2-4pm window) via their online help chat and they "no-showed" and did not even alert me that they had cancelled that appointment. I only found out at 6pm when I got back online to talk to the help chat folks. This is after a message at 4pm that said the technician was running late. I would avoid this company if you live in the Boulder area.

Quantum Fiber outage Fremont

I finally discovered the cause of our month long internet outage on Palatine Ave. My neighbor alerted me to the presence of 2 Quantum repair trucks at the top on the hill on Greenwood. I raced up there and found the technicians getting ready to splice in a new junction box to replace the one that contained our cables that had been gnawed through by a rodent.. Hallelujah. Restoration date 8/21 ….maybe.

High latency at night

I just switch to fiber two days ago and I have major ping spikes in the evening (90 - 130 ms). So far I’ve only tried the standard speed test sites during the problem, but ran tracert to both Google and cloud flare when the issue was not present this morning. I got around 2 on the first few hops and 10 on hop for and five.

Has anyone had any success in resolving a similar issue?

Minneapolis area, Q1000K, transparent bridge mode, VLAN tagging on ONT, 8888 and 8844 DNS.

The only change I have made this morning while everything is working as expected (~1100 up/down 2 ms) is switching to the 1g port. I do plan on periodically taking screenshots of each hop through the day to track. I also plan on trying 1111/1001 during periods of high latency to see if that helps.

Any help is appreciated.

Edit: Sunday night

At about 7pm, it's back

using Quantum, Google, and CloudFlare DNS, hop 2 to 7 are all above 100 ms while hop 1 is <1 ms. Safe to say it's either at the pole or local hub. I'll try the exec and success emails first as the weekend L1 call center is not the best...

Edit 2: Tuesday morning

The lumen exec address got back to me early the next day. Said it’s not their problem as AT&T owns Minnesota (word, fair) but they did forward my email to quantum’s escalation team and gave me a case number.

Edit 3: Tuesday morning

I received a call from the office of the president of AT&T. They are looking into my issue and committed to an update by tomorrow.

Super nice on the phone, already feel way better about switching from Comcast. I am a little embarrassed it escalated so high for one customers issue but it’s a good feeling when you know they are really looking into it.

Tech unable to install fiber

Hello, I was supposed to get Quantum fiber installed at my office today in the Twin Cities area. The tech said he was unable to do the install because the contractors did not install a fiber MST on our power pole next to our office when they did the whole area. Our office is next to a pole that is the last in line where all the utilities end and I guess the fiber contractors only went to the pole before ours. He stated that they need to come back out and finish the job before they can install fiber at our office.

What is a bit confusing is he did not provide any timeframe or ticket number for the job. I got a generic email stating that I need to reschedule the appointment and when I log in to my account it still states the tech is still scheduled today to show up for installation. If I reschedule I can only go out a week which I doubt the outside plant work would be done by then.

I feel like I am going to get the run around on this between support and rescheduling appointments. Has this happened to anyone before? Should I just cancel and keep Comcast Business? I don’t have time to keep rescheduling and having them say the same thing over and over.

Line coming into the house broke, no resolution after tech visits. What is going on?

I've had Quantum fiber for 2 years now and my neighbors knocked over a 4x4 and broke the line coming into my house (not the patch cable) while I was away for work. Forgive me as I don't understand what the terms and/or what the tech was explaining to me. This is the best that I gathered. The tech arrived a week later, and here are the events:

Thursday: The morning of, I receive an notification that the appointment is postponed to the next day (Friday).

Friday: The tech arrives at noon, but needs access to 5 other properties to access the entire line from box(?) to my home. The tech returns at 6 p.m. and trespasses on a neighbors yard to rerun the main line (?) and replaces the modem, but the service does not work. The tech closes the ticket as fixed, tells me not to contact Quantum, and will return Saturday to finish the repair.

Saturday: The tech does not respond to any messages and does not return to the house. I call quantum to scheudle a new appointment. the next available spot is the following Saturday ( 7 days out), but they escalate "in case someone cancels".

Sunday: The tech returns in the evening, and determines that the device on the pole (MST?) is not functioning and an engineer is required to proceed. He also doesn't understand why my house is receiving any signal and can't trace my signal to the box that is 2.5 miles away.

Monday: I called Quantum to explain the past 4 days, but they determine that they can't help and need to send a tech again and will escalate (a second time?). They think the new modem may be bad, and they acknowledge that the repair should not be this complicated. They won't guarantee that the same tech won't return for the next appointment.

What is going on?!??!?!

I have heard that the following is the problem:

  • Bad device at the pole (MST?)
  • Bad modem
  • Bad patch cable
  • Programmer (who is that?) messed up
  • Configuration at the box is messed up
  • Box is too far away (~2.5 miles)

Because of my work schedule, I am bracing myself to be without internet for a month! Is there no way for Quantum to do follow-up appointments when the repair is not complete?

The worst customer service EVER

I have never had such a terrible experience with customer service with a WIFI provider. My neighborhood only takes two different wifi companies, X-Finity and Quantum. Me and my husband just moved to the state and we wanted fiber wifi, so we thought Quantum would be the best option.

When I called to inquiry about the services, I was passed to a manager who was pushing me to set up an appointment day to install. I told him I was just calling to ask questions about the service, not to schedule an appointment. He got so upset and kept telling me to schedule until I just hung up. That should have been my first red flag.

Eventually we did decide to set up with them. The technician was late to the installation service, and it is IMPOSSIBLE to get a hold of anyone. The customer service and the “technical” team over the phone don’t know anything about their services and just tell you to check out the website over and over. We have had the wifi for two months. We pay for the 1G but all of our devices max out at 90mbs. Our wifi randomly went out, we tried calling and again terrible customer service, so we decided to schedule a technician to come out. We called on Sunday, they were scheduled for Tuesday. Sunday night I get a call that our appointment had been moved to NEXT sunday, without asking or anything, the technicians just switched it. I called to try and get my original appointment, and nothing. We are waiting for the technician to show up, which also is a 4 hour window of waiting (8am to 12pm.) Technician is late, again. Have not been called by the technician to let me know they are running late, the customer service say they have no way of contacting their technician or giving me a time, but they will always tell you “we respect your time”.

I am very upset. We do not get the wifi we are paying for, the customer service sucks and is low key kind of shady. The technicians don’t understand the service they are providing and do not respect our time. I believe we will be switching to X-Finity.

Update: Technician showed up 2 hours late at 2pm, without any communication or updates to us after I called the customer service line multiple times. He was there for 3 hours. Apparently the issue with the speed is with their main box that is located on the outside. I live in a townhome, the box is shared by 3 other units, so he said he would have to place a work order to get that fixed, which at this rate I have little faith that will get done any time soon. So at this moment all we can do is wait and request a refund as the highest speed our internet can get to is lower than what we pay for.

Quantum Fiber has been absolute trash...

Was on CenturyLink Fiber for nearly 10 years, 1-4ms latency 0 packet loss. Moved a few miles away to a new house and neighborhood that only had Quantum avaialble; it has been just garbage. Every time a tech comes out they say there is nothing they can do other than swapping out SmartNIDs over and over to the same result.

Im at a lost for what to do.

Help w Century Link Airline and fiber optic?

CenturyLink is discontinuing "legacy voice service" to my area and substituting this "Airline" device they send me, which has one phone and one ethernet port. No mention of fiber optic service or what happens to it.

Does this affect my fiber? I could care less about the land-line phone, but Internet is crucial.

Anybody else in this situation had any luck? I have a separate router and wifi antenna tower. Airline is no help here.

Classic Tech-The worst ISP I've ever experienced

My Wi-Fi has been terrible for the past 3 to 4 weeks. I pay for a 75 Mbps plan, but I'm barely getting 4 to 5 Mbps right now -sometimes it even drops down to 2 Mbps.I’ve contacted customer support more than 20 times. Every single time, they just tell me the cable isn't getting enough power and promise to send a technician. But nobody ever shows up, and they never call me back.This is easily the worst customer service I’ve ever dealt with. Has anyone else run into these kinds of issues with Classic Tech?

Strong work from a QuantumFiber contractor

Who can spot everything wrong with this installation? I've found a few, but perhaps others that know more about networking (and basic pride in work) can help. Unsurprisingly, getting 250 Mbps down, 85 Mbps up. Waiting on resolution from a supervisor.

Quantum can't do installation

Multiple installers have been to our house multiple times and have had the same problem. They need access to neighbor's backyards. They knock on the neighbor's door and no one's home. I give up! I told them to cancel my installation. Has anyone had an experience like this?

Quantum

I just got quantum service this last week the router is in the garage and we have three pods. We have a good string WiFi signal but the internet seems th glitch regularly. It is for short periods of time enough for the tv to go in refresh mode. The download and upload speeds are strong. Should I just dump the pods and hook in my own WiFi system ?

TV's connect to Wifi but no Internet.

Hey guys so my provider is Quantum fiber and I've been having this issue for a while. Once in a while my TV's won't be connected to the internet. This even happens to other devices like my phone and laptop but a router reset fixes the issue on them. For the TVs, sometimes a reset fixes it but the problem eventually returns. The TVs in question are a Samsung and an Insignia FireTV. How do I fix this?
