CR1000A and G3100 MAJOR ISSUES!

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.

dexman

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

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.

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.

dg224

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

dg224

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 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...

dg224

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

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...

Killmas

Not sure if this is related, but it looks like Verizon is releasing a CR1000B in 2023.

Seems a little suspicious that the brand new CR1000A router already needs a revision...

Really do wish that Verizon would either acknowledge there's a defect with the CR1000A that can't be fixed (except with a hardware change) or issue some kind of firmware fix to solve the upload problems.

VoltronTitan

I don’t think this is limited to the G3100 or the Cr1000A because I use a third party high end router and get the same issue. Download speeds are mostly consistent, but upload speeds are laughable, especially for allegedly symmetrical speeds.

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).

famato1

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

dg224

I tried disabling IPv6 many months ago and just again today. No difference whatsoever. I disabled it on both the router and Intel NIC. I've absolutely had it with this issue. Verizon canceled my tech appointment randomly today too. They will be coming out tomorrow. I highly doubt anything productive will come from it. I want the speeds I pay for. I have two houses. One has perfect 900/900+ mbps speeds. Other one literally has 1/10th the speed. Same gigabit plan. Enough is enough. They are scamming me every month by not giving me what I pay for and then making me go through the same nonsense troubleshooting steps 10 times in a row before agreeing to send someone out. I would think they would treat their customers who have multiple accounts with them and are decades-long customers of both their home and wireless service better...

dg224

So after months of issues the problem has been "solved." Two techs came out to look at the network. They saw the upload speeds on my computer and claimed it was a "device issue" very confidently because their own remote test on my network showed normal speeds to the router. Well, as other people in this thread have also noticed, this issue manifests with normal Verizon speed tests but VERY POOR real-world performance. They weren't so confident when they ended up plugging in their own Verizon devices to the router and seeing the horrible speeds. Then they finally admitted there might be an issue after getting 50 mbps on a 1 gbps network... So they replaced the ONT with another Nokia model. When I asked them if they could instead use the new Calix model, they had no idea what I was even talking about. So the replacement Nokia ONT did not fix the issue. Then they wanted to replace the router again. I told them it would be a waste of time because I had already swapped out the CR1000A for a replacement with no fix. So then the tech wanted to try to give me a G3100. I asked if they had any G1100s instead because I used that for 7 years and had no problems (and tried the G3100 a couple of years ago and it was horrible). They didn't, but they were able to go back to the facility to get one for me to use.

So while waiting they tried to troubleshoot the CR1000A. I was told I was having issues with the speed because I changed the WiFi name and password! The issue was occurring in both wireless mode and wired mode. I have no idea how they were able to say that with a straight face. I also mentioned how this was the second router with the same issue. Surely other customers were also complaining about this router, right? Nope. According to them, they never have any problems. By what I have seen online and my own experience, this is basically impossible. Most people using these routers are probably getting much slower upload speeds than they are paying for.

So, as soon as I got the G1100, the download and upload speeds shot up to 900 mpbs. Everything works perfectly. I kind of knew this was the case from the beginning, but I wanted to test Verizon to see how they would respond to this issue and to see if there was a fix for the CR1000A router because they gave it to me for free and I wanted to be able to use WiFi 6E. Oh well. I would rather have gigabit download and uploads 100% of the time instead of having worthless 50 mbps uploads in the real world like I did on the CR1000A. The techs also did not seem bothered by this. They just wanted to get it done and get out ASAP. No one admitted I was right and that the router was inherently flawed to a point where Verizon techs could not get it to work at over 1/20th the speeds I pay for. I also asked if they thought it was an issue between the CR1000A and the old ONT (since CR1000A and Calix ONT rolled out at the same time) and was laughed at (even though they didn't even know Verizon had a new ONT out yet). But my hunch is that it has something to do with the issue.

So my advice to anyone else experiencing this issue with CR1000A or G3100 - GET RID OF THEM ASAP AND SAVE YOURSELF TIME! They are inherently flawed and do not give advertised speeds (CR1000A straight up barely works and gives 1/20th the upload speeds and G3100 has inferior wired uploads to G1100). The G1100 works incredibly well by comparison. As soon as the G1100 was installed, my upload speeds went up by an order of magnitude. Also, don't listen to them when they say third-party speed tests cannot be used to test. With the G1100 I get 900 mbps+ across downloads and uploads on third-party speed test servers. Google Drive uploads of the same file went from taking nearly a day to now 15 minutes. These third-party tests are the best because they test real-world usage and not just meaningless numbers Verizon uses to claim there is not a problem.

Killmas

I love how this thread has a solution now, but the solution is what we've been saying, that the CR1000A is a problem and the solution is to not use it. Not exactly a solution...

dg224

I agree with you. There is no real solution to fixing these useless routers that I am aware of. So the "solution" for me is to use the G1100 because it works flawlessly and gives me gigabit speeds at all times. But when the 2 gbps plan comes to my area I will probably be forced to use something like an Asus router that supports 2 gbps or faster speeds (local network will probably be wired for 10 gbps).

aaronwtfios1

I got a CR1000A a few weeks ago. I have had no problem saturating the 10GbE connection. WIth the 10GbE WAN connection connected to one of my 10GbE switches. And the 10GbE LAN connection with one of my PCs. Transferring between two PCs and their NVMe Drives. I get the same speeds as before the CR1000A was in place. Which maxes out the 10GbE connection at around 9.4Gbps. And over wireless with both WiFi 6 and WiFi6E? I can max out my Fios Gigabit internet connection. Something I could never do with my old WiFi 5 Access Points.

dg224

That's very strange that many of us are having issues with horrible upload speeds that are immediately fixed by switching to a different router but yours is working perfectly fine. Which ONT do you have? The older Nokia one? The Verizon techs saw the issue but had NO idea whatsoever about what was causing it or how to fix it. I am not exaggerating when I say my G1100 gets 10x better uploads than the CR1000A did (and I tried two different CR1000As with factory settings and after being configured).

aaronwtfios1

My ONT was last replaced in 2012. But my CR1000A is not connected to my ONT. I use an Asus router connectwd to my ONT. My CR1000A WAN. Port is connected to one of my 10GbE switches.

I was considering connecting my CR1000A to my ONT, but I decided to keep my Asus router in place. Since I have more info about traffic available. And I plan on picking up a second CR1000A and an E3200. They will replace several of my Asus Access Points I am currently using. That only have WiF5.

JetFixxxer

From what I'm gathering that I shouldn't use the CR1000A over my G1100?

Cang_Household

No, that's the wrong take home message.

There are many users here not realizing that there are other confounds are causing the issues.

One thing to check, G1100 has IPv6 disabled by default, CR1000A has IPv6 enabled by default.

Many Intel based NICs in desktops are defective in supporting IPv6. Intel NICs made after 2021 are rectified for this issue.

Killmas

Have to disagree. Even with IPv6 disabled, the upload issues are still seen with the CR1000A, whereas the G1100 never has issues.

If I could go back in time, I wouldn't have purchased / configured the CR1000A into my network, and just stuck with the G1100. The ONLY reason I haven't permanently removed the CR1000A from my configuration is because its the only router that supports faster than 1Gbps WAN speeds, which will be needed when Fios rolls out 2Gbps service to my area. So I figure (and hoping) that as part of that eventual future upgrade, the ONT gets replaced with whatever ONT supports the higher WAN speed, and the issue gets removed.

dg224

For all of the people just now finding this thread, I would NOT recommend using the CR1000A (as much as I wanted it to work for the WiFi 6E support). IPv6 made no difference for me. I tried turning it on and off and messing with a dozen other settings - nothing could make the CR1000A nearly as fast as my old G1000, and Verizon's techs were completely useless/oblivious to the issue (even when I showed them on my own PC). They suggested I was seeing those speeds because I changed the WiFi password from default (even though I was showing them the issue was also happening over ethernet). So... don't expect any meaningful help from the techs as they only know VERY surface-level troubleshooting (and barely at that). Enough said.

Now if they could actually send out engineers who worked on building these routers and understand the hardware and firmware then I'm sure they could actually get to the bottom of the issue (or if they actually troubleshooted the two CR1000A routers I returned to them for the same issue instead of just sending them out to a different customer). I'm sure internally they know what is going on (maybe a hardware issue?) and that is why they already have a revision in the works. Instead they try to make customers believe there is no problem when there obviously is. Just look on this forum and on Reddit. Many people are reporting the same unusable speeds, even with IPv6 disabled.

aaronwtfios1

I have no problem maxing out my Fios gigabit internet up/down speeds using my CR1000a units with 6Ghz WiFi 6E. But I also do not use either of my CR1000a units connected directly to my ONT.

I can get link rates of up to 2.2 Gbps, connected with Wifi 6E. Assuming I'm close enough to a CR1000a.

dg224

aaronwtfios, I think you're onto something. I have seen a few reports of the CR1000A giving great speeds, but now that I think about it they were ALL cases where the CR1000A was acting as an access point and not directly connected to the ONT. That being said, I can only speak to my own experience of using it while directly connected to the ONT. In that case I had unusable speeds across two different CR1000A routers and two different ONTs. So I think there has to be either a hardware or firmware issue that manifests when the CR1000A is connected directly to the ONT. I would love to hear from anyone else who is using the CR1000A as an access point and not directly connected to the ONT.

JinsengIT

This seems related to my experience. Verizon just sent me a CR1000A to replace my G1100. Everything is fine on 2 laptops (one wired and one wireless) and 2 phones using wi-fi. In fact, the Wi-Fi signal is stronger so we want to use the CR1000A. However, speeds are terrible on one desktop. Disabling IPv6 on the router brought everything back to where it was with the G1100. I'll check tonight, but maybe the NIC in the Desktop is older and unhappy with IPv6.

dg224

I also tried disabling IPv6 both in the router and in the NIC. It made absolutely no change for me and still had the horrible speeds. I'm glad it seems like it might be working for you.

aaronwtfios1

I switched my CR1000A units to pure Access Points. Where my main router assigns all the IP addresses. But to do this, the uplink needs to be on a LAN port.

I had hoped the CR1000A had a true AP mode. Where you connect to the WAN port and select AP mode. That way, I could still use the LAN 10GbE port to connect to a PC.

But I'll just need to keep my PCs connected directly to my main 10GbE switch or to my secondary 10GbE switches. Since the other two LAN ports are only 2.5GbE. I really wish all the CR1000A ports were 10GbE capable, then this wouldn't be an issue.

Plus, using the CR1000A as a true AP, means I cannot access any info from it. I need to move the uplink from the LAN port to the WAN port to be able to make any changes to the settings. But I guess I understand why Verizon doesn't have a true AP option for the CR1000A. Since they probably don't want their customers using it this way.

But my two CR1000A units have been rock solid. So I can't complain. I currently have five WiFi 6E 6Ghz capable devices, with hopefully more coming in the next few months, as I upgrade more devices. So, as an AP for WiFi 6E and WiFi6(with 802.11ax) devices, I have been very pleased with my two CR1000A units. For the devices that are capable, they have no problem maxing out my Fios gigabit Internet speeds over WiFi from the CR1000A.

pius1

Recently got a CR1000A and running into the same issue with my wired moca connection, regular gig download but around 30 upload. What's funny is the only reason I have the gig plan and this new router is because I contacted Verizon a few weeks ago about getting a gimped upload speed on my 300 symmetrical plan and they gave me both these for cheap, only for the problem to be even worse with this new router. It looks like this thread is still live, should I just give up on this router and ask them to replace it with a G1100? The CR1000B user guide is available when I google it, is it in circulation and does it fix this problem?

aaronwtfios1

I just ordered my third CR1000a off of eBay. Hopefully there are no issues with it. Since it is an open box. The first two I got off eBay were brand new. And they have been rock solid.

Killmas

@pius if you are connecting the Verizon router to the ONT and using it as your main router, recommend sticking with the G1100. No fixes as of yet to making the CR1000A when connected to the ONT as main router regaining full upload.

Captain17

Just would like to jump in Disabling IPV6 also worked for me. Made everything go back to the speeds I had with the G1100.

clrones

A guy (ahecht) on Reddit stated the following:

ahecht
·2 mo. ago

As far as I can tell, they're two different versions of the same router made by different manufacturers. The A is made by Wistron NeWeb, whereas the B is made by Arcadyan Technology (the same manufacturer that made the G3100).

The CR1000B is 2/3 of a pound heavier, and while the CR1000A has one light for 1Gbps ethernet and another for 2.5/10Gbps, the CR1000B was one light for <1Gbps and another for 1/2.5/10Gbps. Other than that, the specs are identical.

Aeris

Intel is aware and working on driver issues for this. (I've tried a couple of ethernet cards with both the CR1000A and the G3100 and it doesn't work)

In the meantime I found a workaround. I use a USB-C to Ethernet adapter and get 825 download and 925 upload. The connection is stable and pages download fast. There is no lag.

Hope this helps!

James702283

I was having this same issue after having a c1000b installed which is connected directly to the ONT. I was able to fix the extremely low upload speeds by changing a few adapter settings. I have two ethernet adapters on my desktop pc. One intel and one realtek. The settings I changed on the realtek were disabling “energy efficient ethernet”, “gigabyte lite” and power saving” and changing the speed duplex from auto to my plan speed. On the intel port I just disabled energy efficient ethernet and set the speed duplex to 1GB. I also did this on a second wired desktop with an intel adapter I have in another room. Since doing that my download and upload speeds are both steady at over 900+ MBPS. It seems installing this modem/router changes your adapter settings. Changing those settings to what I wrote above has fixed any issues I had with slow upload speeds.

deeezly

I know its a bit of an old thread, but I'm having the SAME issues with both the CR1000A and my own 3rd party router, but its both uploads and downloads that are effected. If I plug in another internet provider to the same 3rd party router the speeds are BLAZING fast, so it is def. just a FioS issue it seems.

Bandwidth-Hog

I too have this issue. I turned off the 6ghz wifi in my settings.com and my WIRED devices increased from about 125-150 to 500-600 upload. I tried a bunch of things but apparently this had a positive outcome. Good luck. Maybe this will help you too!
