Internet connectivity issue on MacBook Pro with Quantum Fiber service

I upgraded to a newer operating system, and that did not help. What else can cause this issue?

You have made a GREAT connection on channel 11, in the very busy and interference-prone 2.4 GHz band. This band has been mostly abandoned by serious computer users, and has been largely relegated to Printers and other Internet of things devices.


signal strength is OK at -52 dB, where around -40 is right next to your Router, and -75 is unusably far away.

your transmit rate has gone up to the highest available using two antennas on this band, 145 M bits sec.


Why did you not connect on a much wider channel in the 5 GHz band ?

quantum Fiber Router should support and provide 5 GHz band, and should allow you to make a much wider and faster connection using more advanced modulation such as 802.11ac or 802.11ax

I'll be honest, a lot of this is over my head. I'm not really sure how to fix or change anything. But I only have the one option for Wi-Fi. When we had Century Link, we had 2 Wi-Fis, one was 5G and one wasn't.


I've reached out to QF 8 times now and they keep telling me it's my computer and that it is not compatible with Wi-Fi 7.


What do I say to QF if I have to reach out yet again?

I have spent way too much time trying to solve this problem. At first, QF, claimed it was a problem with my computer, since they "refreshed" my signal, and saw no problem on their end. I uploaded a newer OS onto this computer - with much difficulty because of the unreliable internet connetion. I also spoke with Apple Support technicians over the phone multiple times - they shared my screen to try to find an issue - we got disconnected several times, since the wi-fi connection disconnected itself - and nothing was obviously wrong with the computer according to the phone support personnel. I finally made an appointment and went into the Apple Store at Ridgedale, and met with a very patient and helpful "genius" there. I spent 2 hours there, downloaded the newest OS available for this computer, using the store's "reliable internet connection", then he checked various things on the computer. He also did a complete hardware diagnostic test on my computer, and everything checked out fine. The internet stayed connected at the Apple store. So now I'm thinking it's definitely a problem with my QF connection. I explained all of this to a QF customer service person, who was not helpful at all. Then last Friday night our modem accidentally became unplugged from the wall. We plugged it back into the wall outlet, rebooted the system, and "magically" it seemed fixed - worked for more than 2 hours straight the next day!! However, it has recently started acting up and disconnecting about every 15 minutes now - instead of every 5 minutes like before. I called QF customer service again to explain the latest developments, and the rep listened, and said that she changed something (I think she said that she changed DMS on the modem setting to static), and that we should see if that helps. If not call back again, and she'll send a technician to our house to further investigate this issue. I haven't done that yet, but that's my plan for tomorrow. This is all so frustrating, since the old Centurylink wifi worked perfectly on all of our devices!!

it might be. but if is more likely to be a problem between your computer and your Router.


If you would post the parameters, Readers can tell you what is happening in your 'network neighborhood', and whether your router is mis-configured or a whole host of other issues.

Wi-Fi 7 is not what you are asking for -- your Mac can't do Wi-Fi 7 either.


What you want, either from Quantum fiddling inside your Router, or you making your own changes inside your Router, is to enable 5 GHz band, and "automatic" channel selection on that band.

You already have a 2.4 GHz connection. your Option Wi-Fi report showed you were using it.


Most folks do not rely on tech support, but simply surf (with a web browser) to the Router address, and log in to the Router adminisration screen directly. Your Router is at 192.168.0.1 according to your report. Sometimes the default username and password is printed on a label on the back of the Router. In other cases, you may need to download the Router manual.


This gives you access to many tools to make changes yourself, instead of relying on folks who do not appear to be very helpful.


¿What make&model Router?

<< I connected the old one from Century Link via Ethernet to the QF set up and the 5G network came up. >>


that suggests your Quantum 360 Router is not sending on the 5 GHz channel.


as I recall, you were stuck with only a modest 2.4 GHz connection on channel 11, and no way to connect on 5 GHz at all.

We've done both of those things several times. That helps for a while and then the problem comes back. The longest connection has been about an hour. But after reconnecting, the computer stays connected for 10 - 20 minutes, and then the connection drops again. This is so annoying. Quantum Fiber has reset the system remotely too, and this has not solved the issue either. I'm about to call in again and ask that a technician come to our house and look at all of the connections and settings. So far nothing has helped us find a permanent fix.

you could use Wi-Fi preferences to assign your self a Manual IP address close to, but not identical to that one, and that would get you working again. When you change back to DHCP, it will likely-y stay on the manual IP address you assigned for quite a while.


Have you cycled the Power to your Router OFF, counted to twenty, then power it up again? That SHOULD randomize all the IP address again.

A few days ago the system accidentally got unplugged at the wall connection, and we had to reboot/reconnect to the Quantum Fiber service. That seemed to correct the issue for a while - the problem computer actually stayed connected for more than 2 solid hours. However the connectivity problem reoccured later that day, and continues to plague us. I have called QF customer support several times since then, they supposedly reset some of the settings from their side, and we still have problems staying online - online connection holds for between 20/30 minutes sometimes, and less than 5 minutes other times.

Currently the IP address is 192.168.0.8 and the Router is set at 192.168.0.1. Exactly how would I “assign myself a new manual IP address close to but not identical to the current one?” And what does DHCP actually mean?

Again - Thank you for your expertise and suggestions to help us resolve this issue.

the usual way that tends to be trouble free is to set it to use Dynamic Host Configuration Protocol (DHCP).


when your Mac initially starts up, it asks the router for an IP address from the range of local IP address, and uses that one. If your Mac sleeps, it technically releases that DHCP address. When your Mac wakes up, it asks to 'renew DHCP Address'. if available, the Router says "go ahead and use that" else it sends a different one.


somehow, your network seems to be getting confused, and I don't know why.

if you change the IP address from DHCP to Manual, you can specify your own address near the ones already in use. When you set it back to DHCP, it will likely retain the one you manually assigned, at least for a while.


the pool is generally about 250 address (varying in the lowest octet). so any number form the router address at 192.168 0.1 to 192.168.0.250 should work, unless they clash with an existing device.
