Verizon FiOS → Re: [Networking] What level of activity triggers FIOS automatic throttling?

This is weird.

Have you been seeing anything like packet loss on the service, or high latency when the bandwidth is choked down like this? Have you tried rebooting the ONT?

Haven't seen anything on Throttling on FiOS yet. Congestion? Definitely. Bad PONs and ONTs? Yes.

It doesn't seem like packet loss (looking at the error listings on the MI424WR, I see 0 receive errors and 0 receive drops on the traffic monitoring page). I haven't tried rebooting the ONT yet (Lord knows I've rebooted everything else). I will try that when I get home.

Do you think it would help to switch out the MI424WR with my own router (Cisco RV220W); putting the MI424WR on a DMZ behind my router so that the COAX MOCA and the open FIOS ports will still work? (Yes, my network is protected by a couple more routers behind the MI424WR - don't trust the open ports that I cannot control)

I did notice a "LAN Coax Link Low Rate" in the MI424WR system log from this morning. TX 88Mbps/RX 110Mbps at 06:39 and TX 0Mbps/RX 108Mbps at 6:44 this morning.

So it sounds like you are running via COAX/MOCA... If this is indeed the case, have you tried to get switched over to Ethernet and see if the same scenario pops up there?

If you're seeing low link rate, you have a coax or splitter issue.
Any MOCA link rate under 180Mbps is unsatisfactory.

Although a low MOCA LAN link rate indicates a problem between the router and your STBs, you may also have a low MOCA WAN link rate.

No, actually the Verizon router is hooked via Ethernet to the ONT. But I did encounter the Verizon router going to its knees when I was using Rapidfire on Weather Underground. I have since backed off from the update every 2 seconds to once every 2 minutes. Still the MOCA LAN rate occurred about the same time as I measured the drop in internet downlink/uplink speeds this morning.

I wonder if your issue is similar to my old ONT issue. Severe traffic over torrents would cripple my ONT (not my Actiontec or my other router.... only an ONT reboot would fix it!). Do you happen to have a Motorola BPON (something like ONT-1000M3 ?)

At the present time (10:14 EST), it registers 1150 MHz on the Coax channel. Last night starting at around 6 pm, I started having trouble with the download/upload speeds. I verified that there was no correlation with my PWS output. Removing all my internal connections and resetting the router did nothing for the download/upload speeds. Everything came back up this morning around 7 am. I will check again tonight and if I see the speeds drop after 6 pm I will call in a service ticket. I was not successful in resetting the ONT last night (bumbling fingers couldn't get the stupid battery out of the BBU!). BTW, thanks to everyone here for their words of wisdom and suggestions of things to try.

Oh, one odd thing - the system log seems to be missing yesterday's entries. There are three entries for Dec 14, 2007 in its place. Could I have been hacked?

Unlikely. Did you do a reset of the router? That will clear the log.

The Dec. 2007 timestamps are nothing to worry about. THose occur when the router comes up but has not yet synchronized with a NTP server.

I my self had same issues he is describing . A Verizon rep told me the limit on the router is only 5 devices that's what causing the slow down.

I have up to 10 devices connected to my network at once and never have a slow down.

Maybe that`s how they throttle by limiting devices depends on capaicity?

What makes you think they are throttling?

I have 35/35 with far more than 4 devices and have no issues. There is no device limit on FiOS.

I too have a weather station with multiple regular updates occurring, including a 9-second rapid-fire to weather underground in addition to multiple similar "rapid" updates to other sites (including my own externally hosted)

There is something else wrong with the OP's environment that needs to be identified.

Verizon does not throttle, as indicated in prior posts...

I was mostly concerned re the log because an entire day's worth of data was not shown. Later, I discovered that after I downloaded the system log, the missing date's data was there.

I am trying to eliminate my environment as being an issue. I have reset the MI424RW, I also rebooted the ONT, went around and tightened all COAX connections, checked the ethernet connections, checked managed switch settings, etc. I did discover that I had a circular VLAN crossover within my network that was eliminated. I also removed two connections coming into the router so that there are only 4 devices connected to the MI424RW. All this and I found the following:

I did reset the ONT and the router, that seemed to help for a while. There was a definite difference at first, but I did measure the download/upload drop to 0.10/0.27 around 8:50pm. Most of the time the upload held steady at ~20-25, the drop on downlink going down to 2.29, 1.08, and finally 0.10. I am starting to think it may be a clog point in the FIOS network. Don't know, its a mystery, it just popped up this week - I'm about ready to dump FIOS and switch to Cox. But I'm still trying to figure out what the issue is caused by.

I'm starting to see that this might not be a throttling thing. Maybe just a choke point in their network that suddenly cropped up. I want to eliminate anything that I am doing rather than push at Verizon. The question on throttle was based on trying to understand if I was doing something that would cause these slowdowns. So far, it doesn't seem so.
