Upload Speeds

[JesseSA]

Hello

I live in Montgomery County Maryland and have a 1 Gigabit Verizon internet plan. I have an issue with upload speeds where I will get 2-5 mbps when uploading, or speed testing, to locations other than the FiOS test server itself (My download speeds are almost always great). When I test through the Verizon supplied modem’s interface (CR1000A), I will generally get between 900 to 988 mbps both up and down going to THEIR test server. The issue occurs on ethernet wired PCs, wireless laptops and phones. Even when a PC is directly connected to the ONT via ethernet with no modem in between the issue will occur. My ONT is a recent Nokia 3FE52343APBB Rev 2 manufactured in 2023 that is runs inside via Ethernet cable if that is relevant.

I’m very aware of the FiOS IPV6 issue and have tried several configurations. The funny thing is, after some combination of disabling, enabling, disabling IPV6 on the CR1000A and cycling power on the ONT, I will magically get great upload speeds (60 to 150 mbps to far away locations and 600-900 close by), and this will usually last for a couple weeks or more until we have a power blip. The problem is I cannot figure out exactly what the magic formula to replicate this is and usually blindly keep resetting the modem, IPV6 and the ONT until the upload speeds are good again (this can take hours). I have also noticed that when I’m having the slow upload speed I will sometimes get a “Latency Test Error” on SpeedTest.net, or super high ping times. It’s seems like beyond my local FiOS’s initial server outbound traffic isn’t being router correctly. I’ve tried routing through a local vpn, and other random locations, to alter the traffic flow and this doesn’t seem to help either.

I also have a Asus RX88U Pro and using that in place of the CR1000A I have had the same issues. I have been able to get the Asus router’s upload speeds up, but only after doing many random resets of the router, ipv6 and ONT just like with ther CR100a. Just disabling IPV6 will not fix the issue for me. I have IPV6 disabled on all PC’s NIC cards as an extra safeguard. I wonder if somehow the “message” isn’t being sent to the ONT to disable IPV6 and it is rerouting packets from IPV4 to IPV6 when it should be disabled, and that only after a certain number of restarts and disable/enable cycles does this actually occur at the ONT?

This has become a very frustrating task to do every month or so. I found FiOS tech support to be severely lacking in technical ability and overall uncaring as long as THEIR speed test server says its good. Has anyone experience this issue too?

I have, and it's in combination with a multitude of other symptoms as well that are either just as frustrating or even more so. I'm in Delaware County, PA and for a while things were working well, but towards the end of the summer it went haywire after I got 2 new top of the line devices. I can run 6ghz on both and you wouldn't believe how often it's being disabled by something & I cannot figure out why. And no matter what configuration I use I cannot get anything to be stable. And I didn't even bother calling because I already knew I'd get what you had mentioned, tpu hit the nail right on the head. Same deal woth T-Mobile. I call them to ask about something & they know less about it than I do EVERY time lol! I love how no one even answered you too btw, great ain't it?

Just a little update, I know most of the hone networking peeps know all this already. Ive been on a rampage learning as much as I can about all of this. Anything having to do with networking & am about to embark on the long arduous adventure of learning to code/program as I'm attempting to switch career entirely & follow 1 of my "dream jobs". Girdt must come the bachelor's though. I REALLY want to work in the gaming industry, but I'm sure I'll have to entry into a more "mundane" sector of the "software engineering/programming/coding" umbrella term. Either way, concerning FIOS, we should all have ipv6 traffic coming in & out as we are on what's called the "dual-stack" connectivity. Ipv6 essentially rides on top of ipv4 so when testing for it specifically we won't see it. I like to use Analiti, DevCheck, WiFiman, speedtest, Speed Check, Fing, & WiFi Tools/Web Tools apps (in that order lol). They're all spot on w/ eachother. The only thing I don't like, is whilst running the speed test on Verizon app they do literally lie about what you've got connected & after it runs the "router speed " first (which is like saying "this is what you pay for") as if we don't already know. It will than run the test for the device your on. I'm on the 2 gig plan, and in the worst spot in the house it'll give me like 209 down & 100 up w/ on a few devices on at a time. It's strange, than I go to the router website & it says 10 devices connected. They're just so caught up in it now I think if they'd just relax & be open about everything we'd all respect them so much more & would deter alot of people leaving.
