Fios internet intermittent for past 2 months

FIOS_User2022

We experienced internet drops and high latency multiple times a day starting at least June 2022. In the week of Aug 15, 2022, it's dropping internet every hour on the exact same minute. Fios support found an issue (but didn't want to provide detailed info), then said issue was fixed. But Sept 01, 2022, we lost internet for about 5 minutes in the morning, then high latency until this message (Sepr 02, 2022 1051AM).

Can anyone help?

This is a Verizon Fios forum. When trying to help people diagnose issues, I discuss currently available and deployed products on the Verizon Fios network.

The IP TV trials were just that - trials. And the ONT portion of the combo ONT/ROUTER unit did not have a firewall, that was in the router portion of the unit. Same for other combo units possibly used by other ISPs. But none of this helps the OP.

Verizon ONTs do not have firewalls. So there is no firewall in the ONT that could be involved in the problem as their mesh network provider's support claimed. At this point, I believe the best course of action is to test with Ethernet only connections. There may be other approaches I haven't thought of. If you've other suggestions to help the OP, please share.

Welcome to the forums! You're talking mostly with other users here.

That looks like a reasonable trace route. The latency to the destination is 9-13mSec, which is what I expect to one of google's servers over Fios. The latency for the intervening hops doesn't mean much, as the routers may very likely de-prioritize TTL expiration responses; and as you see, some don't even send them.

The latency to the 1st hop (your router) does look a bit long for an internal network. I routinely get sub mSec times on my Ethernet connected devices. If your device is on WiFi, that might explain why it's a bit longer. If not, you may want to explore your network equipment, as it appears you're not using standard settings (192.168.86.1 is not a typical Fios router address)

Hello gs0b,

Having an atypical customer-edge router address could mean there are more than one routable device at home, unless the OP has opted to change the local subnet address. If having more than one routers, then we need to look for duplicate DHCP servers and conflicting DHCP assignments.

Since the OP is apparently doing a tracert on Windows, which is using ICMP as opposed to UDP, and it shows more than 3 hops, this is a sign of IPv6 rollout too as the IPv6 rollout is paired with traceroute fix.

So it could be multiple things going on here.

Questions for the OP

Do you have NVRs on the network? Or other gateway devices?

Did you receive IPv6? Are you using Ethernet or WiFi to connect to the local network? If Ethernet, what is the model of the Ethernet NIC?

Hi gs0b,

Thanks for taking the time.

Yes, the device I used to tracert was on wifi. Anything else you can suggest to help me figure out why in the past couple of months my Fios connection drops multiple times day?

Thanks,

Hi Cang_Household,

Thanks for taking the time.

Here's more details and hope you can help me figure out why in the past couple of months my Fios connection drops multiple times day.

I've been using google nest wifi mesh network since about 2 years ago. Things were fine until about 2 months ago. the nest wifi router was connected to Fios via rj45. the 3 nest wifi points through out the house. About 1 month ago, I had Google Home app generated issue report and sent to Google nest wifi support team. That engineer said maybe Verizon enabled firewall in my ONT and I should ask Verizon to disable it. That engineer also asked me to set google home app DNS to 8.8.8.8, disabled ipv6. I then called Verizon tech support and the rep did not disagree with what google's engineer told me and Verizon tech support rep did testing and said he fixed a issue (but wouldn't let me know more details).

After that, we still experience drops and my company IT installed an app that can show my laptop connection in real time. I see lots of red (high latencies > 100ms) thruout the day.

Let me know if anything else I can do.

Thanks,

ONT's don't have firewalls.

The latency numbers you posted are reasonable for WiFi, especially if you were connected through a mesh node using wireless back-haul. 100Msec latency is not good, though.

You need to rule out issues with WiFi. Can you run with an Ethernet connection for a while and see how it performs? If it works great, you'll know the issue is with the mesh network.

Did you company provide you with "PingPlotter?" If so, that's a good tool to monitor a connection over time. If not, take a look at it. A trial license might meet your needs, or you could buy it. You might be able to find free alternatives, too.

Yes and no.

An example of yes you are correct. At this time ONT from Verizon do not include a built in NAT router.

Examples of no you are wrong...

#1 While Verizon was doing IPTV trails that had an ONT with a built in NAT router.

#2 There other ISPs that with their ONT there is a built in NAT router.
