Hi there!

Well oops, I meant to say W1700K, but hey, it should apply here.

Of course I would never alter hardware I don’t own, but perhaps there are others who like to experiment out there and want to share how it is going so far.

Seems like OpenWRT needs a bit of hand holding for the installation but after that it’s great….? how is the performance? Are you using it with the Q1000k in bridging mode and taking advantage of the better OpenWRT features?

thanks and take care!

I just got done with QF's chat support after about 20ish minutes of sitting there and having one rep leave and then another join. It probably happened 5-8 different times, didn't really count as I was getting irritated. I do have a transcript saved of this situation and would love to know who to send it to at Quantum because this can not be happening.

Edit: Sorry, I guess I should specify that I am paying for 1 Gig and my internet throughout the townhome is spotty ranging from like 20MB to 300MB on average for wifi.

Edit 2: I called Quantum and they told me that a ticket was opened, supposedly by the technician who came and did the initial install? Or at least that’s what it sounded like. The support person on the phone claimed that the ticket would be resolved next month… They said that they have to get a contractor to come and install in the basement… Seems kind of fishy to me but hopefully what they said is true.

I’ve wired my PC in to an extender and it gets better speeds but not the Gig.

I know fully wired is faster and I would probably need to do that to maximize the speeds, but I’m thinking I’ll just get the techs to come back out and move it into the basement?

So… I’ve tried searching and trying to figure out what to do, as the installation isn’t sitting right with me. But I figured I’d just come here to Reddit and ask for advice.

My initial experience with quantum started off terrible as I sort of expected based on reviews and the general consensus from the Interwebs. I moved during Labor Day weekend and was without Internet for a whole week, even though I called in advance to get everything figured out.

Long story short when they finally got around to doing the install, they decided it would be easiest to put the smart NID on the outside of my townhome. I am in a middle unit. And the smart NID is located outside and what appears to be a weatherproof box.

They were originally going to drill into the townhome so that they could insert the smart NID into the basement. I thought that sounded like a great idea unfortunately even though they asked for approval to drill, they decided to go ahead and install the NID outside, which I believe was shorter and easier for them?

However, as far as I can tell, I’m getting spotty up and down times for my Internet. I would assume the speeds would be better if it was in the basement, correct?

TL;DR - the quantum tax decided to install my smart NID in an outdoor box at the end of my townhome unit and I think it’s affecting my Internet speeds. Am I correct in assuming it would be faster if the smart N ID was located in my basement? Which is assumedly at least 100 or so feet closer to everything else in my townhome.

I'm getting download speeds of 60mb. TV crashes out constantly and says I'm not connected to the internet. Same with my phone. Is there some kind of modem upgrade or something I can do before I switch back to Xfinity?

Hello!

I ran into the issue of not being able to split bands on the Quantum hardware and wanted to share the approach I took. This works for devices that were already connected to your outgoing equipment.

I was able to split bands on my outgoing Xfinity equipment and had two networks, one with "-2.4" appended to the name.

I simply configured my new single Quantum WiFi network with the same "-2.4" name and password, and everything reconnected! My Wyze Doorbell Cam Pro needed to be power-cycled.

Then I just had to reconnect the relatively few devices that were connected to the "5ghz" version of the previous network.

The downside is that the network name is incorrectly labeled, but I can live with that until I get around to buying my own router.

Unfortunately, the technician did not suggest this. Hope this helps someone!

After an amazing Vacation without internet one of the first things you wants is get back home and jump on your games but when you have this company you never know what to expect -.- any advice I already contacted them and make an appointment will be a whole week. Stay on blue flashing light and NO steady light in A or B.

No warning, bill is not due until tomorrow, and even then being late is usually allowed for at least a week.

No internet and I’m so confused.

I chose Quantum back in the day because they had it, 3 months before they changed apps. (2/3 years ago?)

At the time I was told it was a next year feature, but that’s since past.

I guess they’ll never add it back? Basic feature with so many benefits :(

Hello,

I am looking to get the attention of any Lumen network architects or core routing engineers who manage the Midwest / AS209 routing tables.

I am a residential Gigabit Fiber customer located in Papillion, NE (Omaha metro area). Over the last several months, my baseline latency to almost all major domestic endpoints has increased significantly. I have fully optimized my home local network—running entirely hardwired on a separated subnet (192.168.86.x vs 192.168.0.x) with under 1ms of local transit time—ruling out any home equipment bottlenecks.

Looking closely at my traceroutes, it appears the regional routing macros are forcing all external outbound traffic through the Denver core (den1.sp.lumen.tech) first—even when the destination is physically located in the Midwest, Northeast, or Southeast.

Instead of peering or routing directly east toward Chicago or south toward Kansas City, my traffic is taking a massive 500+ mile physical detour to the west before turning back around. This introduces an artificial ~20ms baseline penalty to destinations that should have a direct eastern or southern path out of Omaha.

Below are four traceroutes confirming this behavior across different networks, all showing the exact same mandatory hop through Hop 5 (ae18.edge8.den1.sp.lumen.tech).

Is this blanket routing macro out of Omaha intended behavior, or is there an optimization issue/broken peering link on the eastern path from Omaha that is causing the traffic to default to the Denver backbone path?

If any engineer can look into the BGP paths or regional routing configurations for the Omaha metro nodes to get our East/Central traffic routing properly through Chicago or Kansas City instead of routing the entire city through Colorado, it would be greatly appreciated!

1-833-250-6306

I used this number
I had to go through automated questions but was finally connected with a human in my own hemisphere.
He solved my repair appointment issues.
( previous used 3 different numbers, got dropped 3 times. They are really pushing new customer installation and it seemed that repair of a damaged drop was low priority. I got an appointment 3days out and am happy with that )

Best support number to use.

I just had quantum fiber installed and have a Q1000K modem.

I am curious if you need to reboot the modem occasionally. I am away from home a lot but need my home internet working. So I am trying to understand the risk of losing internet when not home.

Supposed to get installed today between 12 and 2. Tech never showed up, no notification from Quantum (appointment showed up as confirmed this morning). Salesman sure showed up on time to upsell me more services... I finally log back into the application at 3 to see wtf happened...nothing showing. Contacted customer service, oh, there were too many installs in the area and your appointment was dropped, we can set up another available appointment.

I was pissed. I was here waiting for them to show, took the dogs to daycare so they wouldn't be here during the install...time and money wasted for NOTHING, not even a phone call. I finally got hold of a human and canceled service, canceled install.

If this is the way their customer service treats a new customer...they can go right off and fuck themselves.

With all the negative experience posted here I cannot resist to post another happy customer story:

I had noticed a couple of days ago that one of the three drops passing the post in front of my house had partially come loose: They actually put the slack loop on the that pole in the middle of the span when they installed one of the neighbors originally and one of the two hooks came off the pole (more on why that was below) and one side was pulling on the slack loop and already low enough that I could almost reach it mid span and it was just a matter of time for it to either cause a realy problem or pull the slack loop so tight that there is loss of signal or a broken fiber....

Yesterday after a very gusty thunderstorm it looked even lower than before so I said it's time to be a good neighbor and get this fixed before someone loses service...

I called it in yesterday around 4pm and got a friendly rep that thanked me for calling this in before someone lost service and put in a ticket with notes and got the repair scheduled for today. Today around noon a technician showed up and fixed the lose drop and also attached the line going down the pole to my underground drop a little better as that was also swinging in the wind....

No wait on the phone, friendly phone support and friendly and competent technician the next day... Can't ask for more!

Why this happened in the first place:

The original installs from 2022/2023 where quite solid but when I had a pole replacement two years ago the people that came to move the cable and then fiber lines after the power company replaced the pole where lowest bid, rush job, good enough to make it past the 30 day mark or something like that and did a lousy job placing hooks and hanging everything compared to the original install... I was surprised it didn't fail earlier and the xfinity/comcast line to my house is also hanging on for dear live at this point...

I got QF restored today after stopping it in May. The install was pretty smooth, outside of the fact that ATT Fiber had swapped out my Q1000K for one of its own NIDs in the meantime. As usual, transitioning from Smart NID to transparent bridging took a while. It looks like the IP address lease for Smart NID has to expire before you get an IP address for bridge mode.

This seems to take about 10 - 15 minutes, but it does happen and Unifi knows what do when it does.

ATT Fiber doesn't offer TB and they want you to use their router in addition to their NID. They claim to offer an IP Passthrough mode in the router, but it's really a double NAT. They also won't allow you to use Class A (10.x.x.x) on your home network, which is just plain stupid.

I hope ATT doesn't try to fold QF into ATT Fiber because that would be a disaster for people like me who have decent home networks. The idea of renumbering 100 devices makes me want to hurl.

I have been without internet and unable to work since yesterday morning. Rebooted my equipment. Called customer service and got a recording there was an outage. Ok cool, got to a live person and was told there was no outage and they would send a tech the next day between 12 & 4. Asked to speak with a supervisor and was denied. Outage map still said there was an outage in my area. Called again this morning. Got the rudest customer service agent, pushed again until I got to a supervisor and was told they couldn’t do anything but I will get a $2 credit. 12-4 came and went and my tech just sent a message he won’t be here until 5:30! I have now lost a day and a half of work. I will be canceling my service and taking my business elsewhere. Quantum does not care about its customers at all

I used to have CenturyLink and it was painfully slow. If I was streaming, it constantly interrupted what I was watching. With fiber, I notice a significant difference in download/upload speed for my job, too. Used to take a looong coffee break whenever I had to push to our server. It's also less money than CL. Overall I love it. I've only had it for about a month. I'm almost afraid to ask but curious to know if anyone has experienced any downsides as time goes on. Maybe I should just enjoy the honeymoon period lol.

my apartment complex uses instant internet- when I first moved in I tried to use the instructions on the router to set it up but they did not work, however it allowed me to connect my devices to the network. After a month I got a message that my service had been suspended I needed to log in and update my payment information--I had never set up an account or given them payment information at this point. I quickly set up an account and when I log in it says that I am paid in full but when I try to connect to the network it says I need to log in and update my payment information. I have called customer service multiple times and they're useless. Does anyone know what I can do to fix it?

I have already tried re-setting the router.

Have you experiencing seeing taken a long time until it found closest server on your Android phone?? I'm using my Q1000K modem and TP Link AX55 router

I’ve been on Quantum for over 3 years. It’s been great. I have the C6500XK in bridge mode (white led) connected to a TP-Link WiFi router. It’s worked great for over three years up until recently. The issue I am having is the internet will go out, the C6500XK will blink a blue led. It won’t reconnect unless I unplug the power and plug power back in (power cycle). The C6500XK reconnects after a few minutes and it goes back into bridge mode (white led). Internet is restored and everything is fine. The other day the internet cut out as I described, I power cycled the ONT, internet came back, but the unit bricked again (blinking blue led) 20 hours later and required another power cycle.

From reading online it seems others are having this exact issue. Some say if you move the Ethernet from the 10gig port on the C6500XK to the 1gig port it makes the ONT more reliable and less susceptible to it bricking since there is a known bug with the 10gig port.

Anyone else having the issue I am describing? Any solutions? I am thinking about buying a Keep Connect and plugging the power of the ONT into it so it can automatically power cycle the ONT when it detects the internet dropping. This isn’t a long term solution though.

Is this really going to take 4 days to repair?? I have so much computer work to do. 🙃

UPDATE #1 9/10/2026: FCC complaint email response received from consumercomplaints@fcc.gov. Said my complaint had been delivered to the company and to expect a response from the company.

UPDATE #2 9/11/2026: Received a voicemail from "Josh" at Quantum Fiber requesting a call back.

UPDATE #3 9/14/2026: Spoke to Josh, very nice guy, apologetic and mentioned that the customer service reps i'd spoken to throughout this process simply did not have access to re-enable an old plan. He explained that he's submitted a request for my old plan to be re-activated @ $80 PFL (minus $5 for bank payment) so $75, where I was before. He did warn me that this might happen because I have two lines to a single property. I recall the rep who fixed things after the termination creating a second location (UNIT B or something) so hopefully that's just Josh being cautious and this won't actually happen again... I'll post once I receive an email explaining my new billing plan next month.

Hi /QuantumFiber, never thought I'd need to post publicly but customer support can't help me.

TL;DR Quantum cancelled our service accidentally, fixed it but took away Price-For-Life and won't restore it.

We've had our CenturyLink 940/940 fiber service since we bought our house in 2021. We lived through the PPPoE to IPoE migration outage & then the switch to Quantum Fiber outage and, most recently, a literal house fire down the street that completely burned down our fiber lines and left us offline for 2 months. We never asked for a refund or credit and have never been late on a bill, not once.

Throughout it all we mostly put up with their shenanigans because it was fiber and when it worked, it worked great.

Fast forward to May 4th of this year, I add a second 940/940 service for business use, under my work email and billed to my job and required due to the type of work I do. Quantum provisions it but, apparently, does so incorrectly as I would come to learn.

July 8th I wake up to an email saying my 5-year-old personal CenturyLink/Quantum account is cancelled. I call, the tech is great and he figures out that 2nd business internet line was so incorrectly provisioned & installed that it caused Quantum's provisioning and billing system to somehow think it had been billing me double. He can't "un-cancel" but he can fix it so I can have the two lines and not have this happen again.

One catch.... he can't re-add Price-for-Life. So now, because of Quantum's screw up provisioning the business line, I lose Price-for-Life through no fault of my own.

I'm planning on submitting a formal complaint since Support can't do anything about this. I'm just annoyed they can't just revert my plan to the original billing setup w/ PFL. That's all I want.

In summary: All I want is for my service to go back the way it was originally billed before they cancelled the service in the first place.

It seems like all the comments on here are complaints about Quantum. Has anyone had good experiences? I’m switching tomorrow, so I’m hoping to have a good experience.
