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?

So good news, bad news:

Good news: My 5 GHz is now 5 days up.  So going to WPA/WPA2 mixed mode may have done the trick. 

Bad news: Overnight my 2.4 GHz kicked off everything.  I know because my wemo plugs and Google Home were either undetected or asking for wifi connection. That's a new one, I think for all of us.  I just rolled 2.4GHz back to mixed mode.  Sigh... 

TL;DR:  2.4 GHz connections may not be safe from disconnects either.

Omg why couldn't I have found this thread a month ago, I've have been suffering this exact same issue and I thought it something internal network related. 5g becomes unresponsive til router is restarted, then is usable for awhile, then refuses to let devices connect, or connect and no internet connectivity.

This thread was started at the beginning of December which is around the time I started seeing this issue, I cannot believe it hasn't been resolved yet. The Verizon service rep that I just did an online chat with told me about the problem that's when I did the search and found this forum.

On the one hand happy to find this thread and know its not just me, on the otherhand can't believe this hasn't been resovled yet.

I know what you mean. I'm ok with a problem if I know what the issue is. At least I can work to find the fix once I know what exactly is wrong. But finding out what's causing the problem in the first place is the headache.

Despite Verizon being aware, have you called and reported to tech support?

[Scoutzer01]

Same issue here with my G1100. It keeps dropping the 5g connection. I spoke with tech support who said that there was a firmware update that isn't working. I would like to know when Verizon is planning on reupdating the firmware and will we be discount on our bill since we're only getting half service.

I'm glad I found this thread as well.  I too have been having intermittent issues with the 5GHz radio for around a month now.

If it is indeed due to a firmware update, why doesn't Verizon just roll back the firmware to the version(s) that worked flawless for several years now?

Same issue here. Instability on the 5GHz channel since late November/early December. I've shut off my 5Ghz channel to temporarily address this bug but I'd like to know when it has been fixed so I can reenable the 5Ghz radio.

For those of you suffering from this issue, turn off your 5Ghz radio and just use your 2.4Ghz radio until Verizon fixes their firmware.

My current firmware version is 01.04.00.12

5GHz works fine for me since I switched from WPA2 to WPA2/WPA mixed mode. It is less secure and not usually recommended.

My G1100 router 5G dropped out once about six months ago. Had been in service for at least a year, flawlessly, prior. Resetting the ONT fixed the problem then, but sadly, not this time. Went through the motions with VZ tech support for an hour or so. Nice guy, "Edward", who finally admitted that there is a known problem with these routers. He did not know when the fix would come down. Offered to send me a new router but said it might fail as well. I opted not to jump through that hoop. Read a lot of "fixes" on http://www.dslreports.com and tried one that was suggested. Changed the 5G channel from Automatic to channel 153. Bingo! 5G started broadcasting right away. 5G has been working for three hours now but I suspect it is just a matter of time before it drops out again. Previous attempts by others to change channels resulted in only temporary success, from what I gather. There are lots of "fixes" on this and that forum and surprising that there are so many users with the G1100 with the same issue. I certainly hope that VZ comes up with a fix soon. My current firmware version is 01.04.00.12

[Downdraft]

Tried the mixed mode but did not work for me. Turned off 5G radio. Waiting for VZ to fix.

Hi all, I stumbled upon this article today: http://techtly.com/if-your-wi-fi-is-acting-wonky-your-google-home-and-chromecast-could-be-to-blame/

I'm not sure if it's directly related to our issue of not being able to hold the 5ghz connection (for those of us that have Chromecast or Google gome devices) but just wanted to share.

I have the same problem with my Quantum gateway.  5G will not stay connected.  Unbelievably bad service from FIOS - they denied there was a problem on the first call.  I got another tech who said they were working with the vendor for a fix.  But how did such a large flaw get past testing?

[McLean1]

I had the same problem for several months. The ONT outside was replaced, the techs did work on the pole outside, I replaced the router twice, rewired my system with cat 6 cable, reset the router countless time and had five different tech visits. Nothing worked. The connection kept failing. Hours on the phone with tech support and the problem continued. Countless tech support chats with no solution. 

I tested the router for a week and it continually failed. The failure would last 3 to 5 seconds and would happen 100 times in 30 minutes.

I finally replaced the Verizon router with an Asus router and this solved the problem. The Verizon router evidently has a fundamental design defect. I put the Verizon router behind the Asus router and the Verizon router would fail but the Asus router did not. 

I have now had almost one month without incident. No router reboots, no dropped signals. 

Bottom line is replace the Verizon router with another high-quality manufacturer's router.

There have been posts on this issue since 2015. Verizon must know their router  has a design oroblem.

My router - in which 5G worked - suddenly stopped working and was replaced with a newer version router.  However, no 5G.

I called customer service and was told that the newer routers need a firmware upgrade so that 5G will work - but that there was no ETA.

[CRobGauth]

What model router did you have before and now?

G1100 is the only FiOS router that supports 5g.

And it has always worked. Latest firmware corrected an issue that could cause some connections to drop.

If you have G1100, have you configured 5g network?

[VZU]

I have been having the same problem since the past 10 days.  Before that the router worked well.  No issues.  Then suddenly the 5G started dropping. The 2G connection stays ok.  Tried changing channels and no use.  Had to reset every day.  I have not added any new electronic device recently. So that is not the issue. 

Got a new router from Verizon as replacement 2 days back.  Guess what,  nothing changed with the new router ! The same issue of 5G dropping and needs reset.  I think this is something to with some software update that happened 10 days beck. 

[WaltO1]

I bought my router outright. Can't call verizon for support. Am I **bleep**?

I've checked the settings. Everything seems ok until I get to the last page in setup and that indicates 5g is disconnected. Any ideas?

[stever1388]

I'm having a similar issue - I got my router maybe 6 months ago, and at some point last week (might have been Friday the 8th but I'm not 100% sure), the 5GHz wi-fi stopped working. It shows up in the available Wi-Fi connections on my phone and tablet, but my devices just aren't able to connect to it (though they try over and over again). I tried setting the channel in the wireless settings, tried 36, 48, and 149 but all stop working after less than a day.

The 2.4GHz connection works fine, though I don't have those connections saved on my 5GHz capatible devices so they don't fall back to it unless I create a new connection to connect to ti (I have SSID broadcast turned off).

Here are the settings I use:

• Channel: 149 (was originally auto)
• Security Enabled: Yes WPA2
• SSID Broadcast: Disabled
• MAC Authentication: Disabled
• Wireless Mode: N and AC Mode(802.11n/ac)
• WMM: Enabled

Hopefully this is resolved soon. I don't want to go through the hassle of replacing the router to find out that won't fix it.

I can confirm the exact same behavior with failed 5 Ghz WIFI negotiation starting in early December for me also.

I saw this behavior from a router which has been working properly with no configuration changes on my part over the last few years. I confirmed multiple different 5 Ghz WIFI capable devices affected. Looking at status of router in console, showed zero 5 Ghz WIFI clients connected, all had seemingly failed over to the 2.4 Ghz WIFI after failing 5 Ghz negotiation.

Based on this thread, I went in on console and disabled and re-enabled 5 Ghz WIFI. I also set CTS to "auto" on both 2 Ghz and 5 Ghz WIFI via the "Advanced" WIFI configuration as this seems to be a generally accepted best practice on WIFI with many devices connected.

I've tested now with two 5 Ghz devices and have been able to negotiation and keep connected to the 5 Ghz WIFI. Hopefully this "fix" is permanent to whatever triggered the original issue, we'll see.

As there has been no configuration or device changes on my part, occams razor would indicate the issue must be due to a change on Verizon's part, likely either a firmware or configuration change to the devices which has triggered this 5 Ghz negotiation issue for multiple FIOS Quantum router users.

I'll give it a try. Did what you said and it started working again in the same way it works again after a reboot. So time will tell since mine would consistently lose 5G connection typically one or more times a day. If this works or fails, I'll let you know here. Not being all that tech savvy with computers and routers, it was difficult to find the correct path to push the right "buttons". Had to sort of interpret terms like "went in on console", and set CTS to 'auto' ". It also wasn't clear to me exactly what menu paths led to the "WIFI via the "Advanced" WIFI configuration" but did eventually figure it out myself. But thanks for your work on this issue that hopefully will lead to a permanent fix.

I do not see anyone else here suggesting to change the CTS to "Auto" as a workaround. We mostly talk about switching from WPA2 to mixed mode.

Also, if your 2GHz is working fine with CTS at "None", you would not need to change that to "Auto"? The CTS Auto will most probably decrease the WiFi throughput. You are right, it is recommended for networks with heavy traffic, but how many WiFi devices do you have?

Please let us know how the Auto CTS working for you.

[TommRXE]

I was hopeful that this was the fix, as it was past one day and still working on 5 GHz. Unfortunately it stopped connecting on 5 GHz again just now after maybe a day and a half. Disappointed this work around didn't fix it. Looks like we will all still have to wait for Verizon to come up with ths permanent fix. By the way, i did check the router to make sure ths CTS was still set on AUTO, and it was. So it's back to 2.4 GHz for me until Verizon provides the REAL permanent fix for us all.
