Thank you all for your advice! Some of it is definitely above my level of expertise, but I can learn. What I found out from the Canon printer manufacturer was that I need an app to reinstall the printer. They walked me through the setup until we got to a point where the app could find my network, but didn't allow me to input password. Canon told me to call Quantum Fiber and switch me from WPA 3 to WPA 2. Quantum told me they couldn't do that. I think the simplest fix is to buy a better printer. Will try a couple more things you guys suggested before I do that.

I have many 2.4 GHZ devices that had no problem connecting to my Quantum Network. I believe they support both.

Quantum doesn't use a traditional modem or router. It functions differently than most other setups people are familiar with. But yes, as I mentioned earlier, you can add your own dual band router and that will likely fix the issue.

Maybe it's different now than it was previously, IDK, but the tech who did our install 6 months ago told me that they now only broadcast in 5 GHz and my 2.4 devices would not work unless I added a separate dual band router. And he was correct.

Almost certainly. Ring uses 2.4 GHz IIRC.

This is so typical of tech support. You do NOT need an app, nor does WPA have anything to do with it. The computer and the printer do need to be on the same WiFi network. You likely don't need a new printer either. I would be happy to try and help you, but I won't be back in TV until December and I doubt you want to wait that long.

If you can position the computer near the printer, you can just skip the Wifi and hardwire the connection with a USB cable.

Here is Quantum's FAQ page on 2.4 Ghz devices. Does this looks easy or intuitive for a non-tech saavy senior? It sounds like you can temporarily use your phone to connect to the devices to set them up, but I don't see how that solves ongoing use. Ring, Blink, MyQ, etc require a constant 2.4 signal to function.

Again, maybe it was different several years ago.

Quantum FAQ 2.4 Ghz devices

With all due respect, I think what the Cannon printer manufacturer told you was total hogwash. You shouldn't need an app to use a wifi printer. I don't know what printer model you have but, when buying a printer, don't buy the cheapest one they sell.

It is at least conceivable that an app is needed to UPDATE the printer. In the old days the update package would be run from your computer and update the printer over the cable. Without a cable, the update package needs to be sent over wifi. Since downloading updates is not a normal function of printing, an app could be necessary.

I had a problem with an older HP printer that would not connect to a new router. It was not a 2.4/5.0 issue but might have been a WPAx issue. I had a nearby computer and cable available and connected it that way rather than troubleshooting the WPA compatibility.

That doesn't seem terribly helpful at all. Sure, you can set the wifi password but there still will not be a 2.4 network to connect to once the mobile device disconnects.

I don't think we have enough information to diagnose the problem. But, apparently, the printer was connected to wifi before Quantum was installed and now it isn't. I have never needed to update a printer to get a wifi connection. I have used an HP plug-in printer app to facilitate printing, but it was not really required. If the printer is old and cheap, I would just buy a new printer, which will probably solve the problem.

Why call the printer manufacturer? I have around 50 2.4ghz devices in my house, do I need to call each of these companies every time I switch network providers? NO! Like I said, I used many of these same 2.4ghz devices in my last home and haven’t changed the ssid’s for over a decade.
I’ve had copper and fiber networks, none of them matter for your internal network.
Just go into the new router, change both ssid’s to match your old wifi name and same pwd and you will be fine. No need to hire anybody for a 5 min job.

And if there is only one SSID because the router does not support 2.4ghz? Or if even that doesn't work because the firmware/hardware of the printer does not support the newer WPA protocol? How do you turn those situations into a 5 min job?

You don't seem to grasp the issue. There is NO new router unless you add one. Quantum doesn't broadcast in 2.4 Ghz, only 5 Ghz, so 2.4 devices will NOT work unless you ADD your own router that has that band and configure it properly.

If the OP owned their own router in the previous installation, and plugged it into the Quantum wall device, then yes, nothing should change. I assume this is your situation and why you incorrectly believe the same situation exists here.

The only thing I agree with is that calling the printer manufacturer is a waste of time.

Nobody knows what they are talking about here. If you just got quantum, they should have given you the latest technology router that should provide the basics: 2.4 and 5ghz wifi bands


This is from the quantum site:

Yes, Quantum Fiber's WiFi 6 plans support 2.4 GHz networks. The 2.4 GHz band can provide good range and coverage, making it a good option for larger homes. However, other electronic devices, like baby monitors and garage door openers, can also use the 2.4 GHz frequency and interfere with your WiFi signal.

And more info from quantum:
Yes, some Quantum Fiber routers support 5 GHz networks:
C4000XG Modem: Uses WiFi 6 technology with dual-band 2.4 GHz and 5 GHz 802.11ax
C3510XZ: You can check if the 5 GHz frequency band is enabled or disabled in the WiFi Settings block on the home screen

I have never seen any router for the past 2 decades that didn’t support both the 2.4ghz and 5ghz wifi bands

To the OP, if you have a router that doesn’t support both the 2.4 and 5ghz wifi bands, (all routers should, it would be very odd that I doesn’t), you have 2 options:

1) tell quantum you want a router that has both 2.4 and 5ghz wifi bands and then configure this router using your old wifi name for both ssid’s

2) send back the quantum router and buy 1 or 2 mesh network routers that support wifi 6e which will also support the 2 wifi bands. Then configure these mesh routers to use your old wifi network name for both wifi bands and use the wifi 6e band as the backhaul for the mesh routers
