CR1000A and G3100 MAJOR ISSUES!

[dg224]

Hello. I’m extremely frustrated right now after having these issues. I have been a Fios customer since 2014 and originally received a G1100 router. This router performed flawlessly and I had a great experience. I even kept the same one while upgrading to gigabit service in 2015 or 2016 - no problems. I always got 930/930 speeds, even on third-party sites like Speedtest servers. In 2020, I decided to try to upgrade to the G3100 to try to take advantage of WiFi 6. The wireless speeds were a bit better than the G1100, but I was surprised to see that the G3100 was maxing out at only around 200-300 mbps upload when my old G1100 could easily do 900 mbps. Since I care more about wired speeds than wireless ones, I returned the G3100 and kept using my G1100, figuring it was a defective unit or some kind of firmware bug.

Now recently I have moved and received one of the brand new CR1000A routers with WiFi 6E and all the other great features like 10 gbps and 2.5 gbps ethernet ports. Awesome. So imagine my surprise to find out that it’s just as worthless as the G3100 and vastly inferior to my old G1100 router. Now I’m lucky to get 100-200 mbps upload speeds over wired connection directly to the 10 gbps port (tried all the other ones too). What’s the point of having these ports if they can’t support these slow speeds? I already tried to manually set the ports to 1 gbps mode - no change. I tried to adjust WiFi settings and remove QOS to maybe reduce CPU usage - no change.

Another thing that I find very strange is that Google Drive uploads actually are maxing out at 50 mbps. On my old G1100 they would usually sit well above 600 mbps, making my actual work-related upload times a staggering 12 times longer than they previously were - essentially unusable while using the fastest fiber tier Fios provides in my area with their newest cutting-edge router. So does anyone have any idea what is going on with these two latest generations of routers? It’s unfortunate because I really love the Fios service. I just don’t get why they’re putting out routers, intentionally or unintentionally, that absolutely do not allow the client to take advantage of the speeds they pay for.

What is the link speed of your Ethernet?

G3100 has an internal switching capacity of 3Gbps.

While CR1000A's 10GbE ports have 160Gbps.

[dg224]

The desktop PC has a link speed of 1 gbps. During my troubleshooting, I also switched the link speed for that port on the router from “auto” to manual 1000 mbps. The ethernet cable itself is the same one I’ve been using for years to get 930 mbps down and up.

Please verify if Verizon has enabled IPv6 service at your location.

[dg224]

IPV6 does not appear to be active from the router settings. Is there anything else I should be looking for?

[Cang_Household]

This is definitely not IPv6. G1100 would have IPv6 enabled as well if the OP has received IPv6.

Could you see which LED on the router's port is lit? Is it the upper one or the lower one, or both?

Did you use the official VZ speed test? Does it show the same problem?

Or try wireless, WiFi 6 is capable of pulling 900Mbps+ with the router insight on a 2 x 2 MIMO client.

Official Verizon Test: Router (948/802)

Official Verizon Test: Device (911/885) - Impossible that this is correct. Also showed 3000 for download until the very end. If it is somehow right, Verizon is favoring this test's traffic because these results are nothing like what I am actually experiencing.

Google Speed Test: 898/19

Fast Test: 760/190

Google Drive Upload: 50 - Used to be about 700 with old router.

Box Upload: 60

Xfinity Test: 875/107

Verizon is intentional sending out routers that throttle computer uploads. It's the only logical explanation. 

[Cang_Household]

I am going to test my CR1000A with two 2.5GbE adapters one at the WAN side and another at the LAN side to see.

That’s seriously the least logical thing I’ve read today. Intentionally throttling a 1000 mbps connection to 50 mbps (5%) will just lose you customers. Even Verizon isn’t that stupid. To troubleshoot, first reset the router to factory settings. Disconnect the MOCA coax cable from the back of the router. Connect only your computer to the router with cat 6 or better cable, turn off all of the Wi-Fi radios on the router,  and run speedtest.net every 30 mins. or so for 24 hours to rule out any network issues. Verizon‘s 1G plans typically deliver 800 to 900 mbps up and down. If that all works then reconnect the coax and run the text again. If it fails this time, you have some kind of problem (noise, usually) on the coax side, which connects the router to your TV boxes. This is not unusual and Verizon will need to do a house call to figure it out.  If that all works then get yourself a Wi-Fi scanner and look for local interference from your neighbors or your own other access points. This is easy if you have an android phone, not so easy with iOS. I use wifi analyzer pro (https://www.wifianalyzer.info).  if there is no interference, you can try turning off the self organizing net work and exposing the 5GHz and 6GHz  networks with separate AP names, and try attaching to each separately. Some devices, especially Apple devices, will often attach to the 2.4 GHz net work, even though the faster networks are available at high signal strength. I had this problem with my MacBook that could definitely be causing a low connection speeds, though nothing in the range of 50.

Sorry, I’m not sure what you mean with the LEDs on the router. Looking at the back, I’m only seeing LEDs on the top of each port and on the left and right.

[dg224]

I'm not sure if you saw my most recent message, but I just tried with WiFi 6E. Same issue.

[dg224]

Just contacted Verizon support. They want to send me a replacement router. I doubt it will fix the issue, but I obliged. I tried connecting directly to the ONT and got much more respectable uploads of 700 mbps+ compared to the 50 mbps I was getting going though the router. The issue is also inconsistency. Sometimes though the router the speeds are "okay" at 200 mbps (still a horrible result) and other times they're abysmal at 50 mbps. I really need to be getting the old 900 mbps+ speeds I used to get. Maybe a slight ONT issue or saturated line to my place combined with an issue at the router too? It really blows my mind how this brand new 2022 model router could be the problem and giving substantially worse speeds than a model I had from 2015. Do I just need to get my own powerful router because this CR1000A won't cut it for even gigabit speeds? Maybe build something custom? Can't deal with this inconsistency and slow upload speeds. It's impacting my work.

So I received my replacement CR1000A. I plugged it in and swapped my PC over. Still only 50 mbps upload. Tested on both ethernet and WiFi 6E. Tried a brand new CAT 7 cable even though the previous one was also a new replacement. Now I finally managed to get a 700 mbps upload result. By the time I went to test it on my other PC, it had already gone back to 50 mbps max. Then I went and tested it again over ethernet - once again only 50 mbps. So the issue was fixed for maybe one minute total. So the new router did not fix the issue at all. The only time I’ve gotten a good result is right after I switched the cable from the ONT to the router (and it only lasted a minute). Maybe because the ONT or router rebooted or something? Does anyone have any input? I don’t think Verizon should really ask a customer to do more troubleshooting than I have already done. I don’t think most people are willing replace the router, multiple ethernet cables, use multiple PCs for testing, manually change many settings, and even buy a PCIe WiFi 6E adapter for additional testing. I just want the speeds I pay for, not literally 1/20th of the speed. I can’t take another chat with them trying to ask me to do basic troubleshooting steps.

Stop wasting time with the new router CR1000a. It's very buggy. Speed is not stable, wired and wireless. The 6E band is a joke.

[LRY1]

I’m having the same issue. I had the old Fios router and it work flawlessly. I then purchased the new CR1000A and the router extender just two weeks ago. Amd now having major issues. I contact Verizon and all they say is the internet is working fine. They do a reboot and works great for a few hours and then the same problem. 

[dg224]

I decided to buy a WiFi 6E PCIe card to test that too so I could show there is something very wrong here. Download speed to the same SpeedTest server I always use: 870 mbps - great WiFi result. Upload speeds: 60 mbps. What is going on? I guess it's not related to wired connections only, for me. For reference, using a wired connection with my old G1100 got 930/930 results, so it's not the server or my PC...

[anossier]

Same boat here, owned the G1100 for many years and got the new CR1000A today. Uploads are extremely slow. Please post updates.

[Killmas]

So I have literally the exact same problem going on with my CR1000A (upgraded from G1100). Verizon speed tests run great, any other speedtest site shows significantly slower (~200-250 Mbps) upload speed (again same conditions, using the 1Gbps plan).

I have tried playing with the firewall settings to no avail. I also tried using the router connected to a 1Gb interface (instead of a 10Gb interface) to see if that made a difference, but also to no avail.

I think this is isolated specifically to the router (or some interaction between CR1000A version router and ONT), because I still have my G1100, and when I swap it back instead of the CR1000A, my upload speed via external speedtest sites returns to expected upload.

What is interesting (I guess) about this problem is that download seems completely unaffected. Only Upload is a problem.

Note, I have tested using the 10G LAN1, and both LAN 1/2 (i.e. the 2.5 Gbps ports) on the CR1000A, connected to a Mikrotik S+RJ10 (capable of operating at either 10G or 2.5G, which I did see correctly switching for the correct interface speed depending on which LAN port I was connected to), and I also tested to connected to a regular 1G RJ45 port. In every scenario, upload speed is slower than expected, except when measured via the Verizon speed test (all other speed test sites come back as slower than expected).

I am wondering if this can be fixed by Verizon via firmware/software update, or if there is some latent defect with the router hardware. I have to imagine, given that I don't "think" Verizon is lying in their speedtests, that this is something that can be fixed in the firmware/software of the router. It would be nice to hear from Verizon that that is in the cards though...

[dg224]

It's interesting to see that so many people are also having similar issues. At my other house with my old router on the gigabit plan I was getting 900 mbps uploads at all times (and still am). Today at a different location I am still getting 50 mbps uploads on a 1 gbps plan (with the new router). It's insane. Like some other commenters said, the Verizon speed tests always somehow seem to be fine. But then any actual real world use drops harder than I have ever seen before. Things that would take me 20 minutes now take almost 7 hours. It's completely unacceptable (yet they are happy to keep taking my money every month for the gigabit plan). I keep getting generic answers from customer support agents who don't have the faintest idea about anything related to how the routers actually work and the hardware and firmware... I will have some respect for Verizon again when they connect me with an actual engineer who can either admit the routers are MAJORLY flawed or provide a single working solution (I need to keep using Verizon's router because third party routers seem to change the IP dynamically more often, and I need a static IP).

Disable IPv6 and your issue should be resolved. Curious to hear how it goes.
