Quantum G1100 Router suddenly not keeping 5ghz connections

[RichLux]

For the past 2 weeks or so, my G1100 router will no longer connect reliably at 5ghz. My devices will connect and then immediately disconnect or refuse to connect at all. If I reboot the router or change anything in the wifi settings that causes the router to reset the wireless, 5ghz will work again for a day or so, but then the same thing will happen. I have tried many different 5ghz channels, but none fix the issue for more than a day or so. I have no issues with 2.4ghz, only 5ghz.  Prior to this problem recently, everything worked fine for over a year. I posted over at DSLReports and one other person has the same issue, but no one has any resolution to the problem.

Has anyone here seen this issue?  Does anyone know if Verizon pushed a firmware update over the last 2 weeks?

I'm not sure if it's large numbers but it's clear a small subset of users are being impacted by this bug.  There may be a lot more people with the issue who don't realize it because their devices could be falling back onto the 2.4ghz band.   

So it's all unknown but worth everyone on this thread to call Verizon and report the matter when they have the chance. 

Something happened in the last 2 weeks and it couuld be a bad update they pushed to our routers. 

[RichLux]

Hmm, Branch usually has good info, but that post is from 2016 and it sounds like it was for IPTV (there's no MoCA), so I wonder if they shelved it when they shelved IPTV.

Yeah, me too.

5Ghz network just started acting up, not connecting, showing as an available network but no signal.  All the in the past two weeks or so.  I wonder if Verizon pushed a new firmware update recently?

[pdroth]

Me Too - 5Ghz fades out after about a day or two requiring a reboot to bring it back to life.

Twitter support was no help.  It's infuriating.  0/10 would not do again, and suggest others do not do the same.  No idea how to get this higher up the food chain or if it already is.  Not sure what to do at this point, because I paid outright for the Quantum Gateway.  I don't want to have to buy another router if I can help it.

"I can not explain about any other router, but I can tell you about the gateway" 

- FML!

Jumping in on this bandwagon here. My 5G network started crapping out on me this past Friday, the 8th of December.

Resets / Reboots / channel changes / etc. only give me momentary relief. The 5G is broadcasting but only getting <1Mbps download speed and not letting me connect to it.

I just read over at DSL Reports that Rich was told to change the names on the 2.4 Ghz and the 5 Ghz and that it should help the issue.

its worth a try in any case. I am sure he will let people know if it worked for him.

jonjones,

Thanks for the quick reply and continual support on this topic. I factory reset my router/modem Sunday night. That did change the SSID of the networks along with the passwords and configurations. 

5G was up and running good. But when I awoke this morning, it was down again.

Something I've not seen others coment on here, Wifi Info View shows a second, 5G band broadcasting from this router, no SSID, but it is the same channel and the same MAC address except for maybe 1 or 2 letters. Does anyone know why it would be doing this?

To clarify, in my investigations this weekend I found the 2.4G network being broadcast, the 5G network being broadcast and a 3rd, unnamed, identical 5G network. Could this phantom network be causing the interference?

[jonjones1]

The Quantum router has three broadcasts.

2.4 Ghz 

5.0 Ghz 

Guest Network (I don’t use the router so I cannot say what band it uses)

although many here are complaining about 5 Ghz which is faster, but not great in distance as 2.4 Ghz due to restrictions on the 5 Ghz the overall speeds vis a vie I cannot say. 

The other poster was wanting to know if it made any difference evidently it does not.

I am seeing the "phantom" network being broadcast on the same 5 GHz channel (using WiFi Analyzer on a Samsung Tablet).  The guest network is disabled.  When I change the channel on my 5 GHz, the phantom network moves into that same channel. I have a feeling that Verizon is (or was) trying to do the same thing that Comcast/XFinity was doing with having their users routers act as hot spots for all XFinity customers.  When I was with Comcast I had to call them and request that the XFinity network stopped being broadcast from my equipment......  

FYI,  I have my SSID for 2.4 and 5 GHz different names.

I am having the same problems with the 5G wifi network and I have called Verizon numerous times nd I get the answer: It is a known network issue.  Changing the router will do no good, since it seems to be in the network.  

I have also seen the "phantom 5G network" that comes from my router.  It is a strong signal and it goes up and down in strength like a wquare wave.  It is on the same channel as the home 5G network and when I change channels, it changes too.

No one at Verizon has ever heard of this phantom network.

No phantom networks here. You may need to reset your router, or at least reboot?

I'm nearly positive that the "phantom" network is coming from a chromecast or google home on your network. I believe that is how they enable "guest mode". Shouldn't really be a problem, and you can try turning off guess access in the Google Home app. I believe turning off the guest access stopped the "phantom" network from showing up for me.

[Candlestyx]

The phantom network comes from the router and disappears when the router is turned off.  There are no guest networks and no chromecasts.  It always occupies the same channel as the 5G network.  As others have written in these posts, I can reboot the router and the 5G network stays active sometimes for several days and then it myteriously won't connect.  Signal strength is strong but it says it can't connect.  I have Comcast at my second home and their new system is much better and the TVs are much sharper than FIOS.  I will likely change to Comcast.

[Simbapenn]

Changing network names did not work for me, FYI. 

[E_Slaptyback]

Having the same issue, I thought it was due to my Nvidia Sheild TV sitting RIGHT next to the router and causing some sort of interference.  Now with that said I powered off the Nvidia and was able to get it to stay up for a week or so and I thought THAT was the issue but it JUST raised its ugly head again after thinking it was solved.......

I did a complete factory reset on the device and set it back up from scratch prior to powering off the Nvidia Sheild TV device.

This cannot be coinkydink that so many users are having this issue.......

I wish it were that simple, but the router didn't crap out.  The brand new replacement I just got has the exact same issue.  Everyone having the problem says it started about 2 weeks ago.  There's no way this is a coincidence.  Something must have changed in the firmware recently.

Rich

 I am in agreement with Rich --  I have had this issue in the same time frame.. going on about 6 weeks now (mid to late Nov '17).  Seeing the number of people with the same complaint - it does not seem that just replacing the router is the solution. 

 In my household, wireless devices operating include - BlueRay DVD, HP Printer, 2 diff iPads (pro & air) iPhone 6s and Samsung Note 5 smartphone.  No hardwired devices seem to have any connectivity issues.  The only devices that seem to be bothered are the iPads and Smartphones --  The iPads most severely.  In my case I use the 5ghz connection as the primary and the 2.5 ghz as the guest connectition.  Each of these are set up to work with 5g 1st and in case of the iPads - the will not select another service and when you force it to use (fake name) MYPrimary it will report that the password is incorrect.  Pick MYSecondary and it connects immeadiately.  To resovlve, I reset the router manually or have MyVerizon do it remotely (issues here too but.._) when that is completed, the same devices that reported bad password connect instantly.  NOW put that device to sleep and INSTANTLY it loses that connection again. 

The iPhone and Note 5 will last longer - the Note 5 in particular, BUT it does happen to all devices EVERYDAY...   and many times during the day.  Five / Six weeks ago it was sporadic - a few times per week and then everyday....

SO - it must be more than just get a new router.  If any additional info is needed to help me and the MANY others to resolve this please let me know. 

I am going to continue reading here and hope to see something good already posted.

My connection has been dropping off, since it was installed. 10 yrs ago, I'd have it fixed. I'm disabled now, and just don't have it anymore, it's frustrating. The bill is already high for me, but it is what it is. This router sucks! I don't have money to buy a router. If a company provides a router, and the customer pays for it, Verizon isn't losing - the customer is!

[CRobGauth]

Wifi can be problematic.

5 Ghz does not penetrate or carry as far ar 2.4 does.

Quantum router is a middle of the road router.

You basicaly get what you pay for.

If you really want/need improved performance, you will have to buy a higher class router.

[Jmwalker36]

Except I’m sitting so close to my router that it could be a ‘plug’... and Verizon knows it’s an issue, the contract states that the router I pay for will provide a service that it doesn’t!!!  Then when you contact their ‘customer service’, you get the run around & no solution!!!  Unacceptable.

[reesedp1]

Verizon told me yesterday that it was a recent firmware update that's causing the issue. They don't know when it will be fixed....
