Data rate change...?

[chalktrauma]

I have a 1.5/384 plan and have had decent speeds since I joined. Recently I noticed a significant drop off in download speeds, upload seems to be unaffected. I've rebooted everything involved, modem, router, switch and replaced all the cat5/6 cables and phone cables. Nothing has made a difference, so I ran the Westell diagnostic tool ( modem browser ) and got the following results:

The data rate is lower than what I was getting when I first joined Verizon DSL:

Do any of these numbers look off to anyone compared to what they use to be?

The data rate difference seems to be consistent with what I'm seeing in the speed tests:

Why has the data rate changed?

It's congestion and there is nothing you can do about it. You will have to wait for Frontier to fix it because Verizon isn't going to do a thing with it.

Verizon over sold DSL lines and didn't upgrade their COs and now we have congestion in the evening. Run a speed test in the morning and your speed will be normal.

Your speeds don't look bad for your plan. I have 3mb/768 and my test are lower than yours in the evening.

I'll try a speed test in the morning then and see what I get..

One question though.. How does conjestion effect the change in my modem data rate settings:

The difference between those two.

I thought the data rate reported by the westell modem browser was the ATM sync level which is the speed the line is provisoned for?

Here is the FAQ entry for the Westell Modem Browser utility:

If I understand the reading correctly it looks like my noise margin has gone up ( which is good ), but only because my line was re-provisioned at a lower rate which helps the signal to noise margin.

I can see how conjestion can effect throughput but that should have no effect on the data rate provisioning the modem is reporting when it syncs to the DSLAM.

I don't know about the Modem Browser utility. Login to your modem and it should show you the data rate on the first page of the UI.

I can't login to my modem, it is an old Wirespeed B90-36R5 in bridge mode, there is no web UI, you need the Modem Browser with a direct ethernet connection to access it's diagnostics. I normally have it connected to my router through the uplink port running Tomato which makes the pppoe connection to verizon.

To be clear I'm not talking about download speed or throughput, I'm talking about provisioned data rate that the modem detects when it syncs with the DSLAM, which should match with the 'Plan' that you have with Verizon, they are the ones who set the max data rate. What kind of throughput you get depends on traffic but you will never get anything better than the provisioned data rate set on the line, and that is why I'm wondering why mine has dropped by a 3rd.

[nospeedinternet]

I know what you was asking but I am wondering if the Modem Browser utility is telling you about provisioned data rate or not.

[chalktrauma]

Ok.. thanks.. just wanted to make sure I was explaining things correctly,

According to all the docs for the utility that is the provisioned data rate. I'll check it a few more time at different hours of the day and see if it changes at all.

According to the FCC docket Massachusetts is not one of the states affected by this change.
