Something fishy here?

cjs2012

I got rid of my old Westell 6100 because it kept losing speed over a period of several days or less, fixed temporarily by a reboot. It got so bad that I had the Tech come out and check the lines inside and out. Everything tested good at up to 10Mbps. I changed to an Actiontec GT784WN modem/router a few weeks ago and the speed improved quite a bit. My 3-7Mbps account hit 7Mbps for the first time ever and even though the 7 wasn't consistent I did have 5-6 all the time. Now, and within the last few days, all I can get is 3.1Mbps. The speed won't go higher and a modem reboot doesn't help.

Seems a bit fishy that after consistent 5-6Mbps service for the last several weeks the speed has been cut in half almost overnight and now appears solidly at the bottom end of my service level.

Step one: Visit http://www.giganews.com/line_info.html and post up the Traceroute the page shows, if you wish. Be aware that your non-bogan public IP Address will show up. It might shown up as the final hop (bottom-most line of the trace) might contain a hop with your IP address in it. Either remove that line or show only the first two octets. What I'm looking for is a line that mentions "ERX" in it's name towards the end. If for some reason the trace does not complete (two lines full of Stars), keep the trace route intact.

For example this what I saw when I was using Verizon

news.giganews.com

traceroute to 71.242.*.* (71.242.*.*), 30 hops max, 60 byte packets

Step two: Can you provide the Transceiver Statistics from your modem?

#3 For the ActionTec stats, I am not as familiar with that gateway, but you may access the web interface at http://192.168.1.1/. Just log in with one of the following usernames and passwords:

admin/password

admin/password1

admin/admin

admin/admin1

admin/verizon

admin/verizon1

Once in, go to the Status pages of the modem using the top navigation, and then select "DSL Status" or WAN Status." You should see information such as your line speed, attenuation, SN Margin, line mode and transmit power. You can screenshot or copy/paste this info into a post.

Your line is on the long end of the scale for a full blown 7.1Mbps connection to be solid. As shown by the modem you're hitting a number of uncorrectable errors on the line. Have Verizon set your connection to 5Mbps/864kbps and disable the ASSIA Optimizer. From there see if your connection is any more stable. If it holds for a while and the stats look good we'll see what we can do to get you a 7.1M connection.

One thing I like to ask is, if you have a landline with the DSL Service, do you hear static, buzzing or popping on the line? Noise like that is indicative of a connectivity problem in most cases with the lines between a device in your home to Verizon's CO. Or, it could just be the phone itself. None the less, if the noise is being caused by a fault on the line that will degrade DSL service.

I do know that I'm on a long line but the tech was here several times and the line tests good at up to 10Mbps. I also do have a landline but there is no buzzing or other noise. My filter is at the Network Interface outside the house and I have a new CAT5 cable running directly from the box to the modem. The filter is also new. Basically, I'm filtering the phones at the box and running a separate line the the modem.

Who do I call to reduce the speed and disable the ASSIA? Reading here show that there is some adverse reaction by Verizon to disabling this.

cjs2012

Another tech visit, line checks, blah, blah, blah.

I talk to the tech about the ASSIA stuff and dropping the setting to 5Mbps to see what happens. Won't happen for a week.

That should take less than a minute to apply on the backend. It takes more time to wait for the line to come back up and test.

You will be able to get 7.1Mbps with ADSL2(+) if Verizon is able to supply that. You're still on regular ADSL per G.DMT mode appearing. 10Mbps is still cutting it, and it's likely you were given the theoretical max as given from a sunrise meter. Modems rarely are able to hold at the theoretical max for more than 20 minutes.
