Verizon will sell you a new one, and if you happen to get lucky and get the right person on the phone, may give you one (good luck there). Best deal is usually E-bay. Just make sure if you get something different than a 2200, that it comes with the plug as well. They aren't interchangeable.]]> http://www.dslreports.com/forum/remark,20602195 Fri, 06 Jun 2008 14:43:53 EDT Re: [connectivity] Confused about slow line speeds http://www.dslreports.com/forum/remark,20599755 Bytebender : That depends on when you got the modem/router in question. The warranty used to be a year but I believe that has changed and is now either a month or three with an option to pay for extra protection.

But nope, didn't work. I waited until the margin came up to 15, disconnected, did a manual reconnect (or on demand, same difference). Still refused to connect at a faster speed.

Only a power off and on seems to restore 3360.

What is Verizon's modem replacement policy? I was looking in the revised TOS (got the Email) and couldn't find it.....

*** EDIT ***

Doing a Maintenance / Backup/Restore / Restore operation seems to be the most painless way to reset the modem if I'm too lazy to get up and turn it off and on. Of course I backed up the current configuration first, but I only have to do that once.]]> http://www.dslreports.com/forum/remark,20599733 Fri, 06 Jun 2008 03:48:54 EDT Re: [connectivity] Confused about slow line speeds http://www.dslreports.com/forum/remark,20597415 Jodokast96 : No, it won't increase on it's own. Instead of turning it off, you can access the modem and drop the connection and reconnect from there. If the margins are up, it should sync at full speed.]]> http://www.dslreports.com/forum/remark,20597415 Thu, 05 Jun 2008 17:47:52 EDT Re: [connectivity] Confused about slow line speeds http://www.dslreports.com/forum/remark,20597203 dsldan : OK, let me try again....

When I first turn my 2200 on, it comes up with a Margin (db) of between 0.5 and 1 and a download speed of less than 1700.

Gradually (as the modem warms up???) over 10 minutes or so, as I refresh the transceiver page, the margin increases to greater than 13, sometimes going up to 15.5 or 16.

But the speed never increases. It stays at the initial low value.

But then, when I turn the modem off and on, it finally comes up with margin greater than 13.5 and speed 3360.

Question:

If the margin is increasing, why doesn't the modem increase the speed by itself? And is there a way to get it to increase the speed without turning it off and on???]]> http://www.dslreports.com/forum/remark,20597203 Thu, 05 Jun 2008 17:00:39 EDT Re: [connectivity] Confused about slow line speeds http://www.dslreports.com/forum/remark,20527390 dsldan : There is no doubt now that when my 2200 is first turned on, it starts with a Margin (db) of between 0.5 and 1

Only after being on for awhile, when I turn it off and on again, does it sync at 3360 with a margin of > 13.

And then once it gets 3360, if left on, it can retain this speed for days. That rules out a line problem.

This is consistent over several weeks now.

What is this, a car engine in winter? Does it have to warm up before syncing at maximum speed?!?!?!

Try explaining this one to a Verizon tech.... oh lawd.......

-> Is there any way to reset a Westell 2200 other than turning it off and back on?]]> http://www.dslreports.com/forum/remark,20527390 Fri, 23 May 2008 03:01:05 EDT Re: [connectivity] Confused about slow line speeds http://www.dslreports.com/forum/remark,20438332 dsldan :

When the modem is turned on by the power strip ... i.e., the rocker switch on the back of the modem is on but the power strip is off and then turned on ... I am more likely to get a downstream margin of 0.5 or 1.0... but when i turn the modem on separately by the rocker switch, even just a few minutes later... i get 16.
Is anything else powered by the Power strip? If what you are seeing a reproducible condition it may be noise from other equipment is affecting phone line.

May want to check wiring and modem/router location. Try moving things around a little.

When I leave the modem on, it seems to be able to retain 3360 with a margin of 15.5 or 16 for several days.

But when I turn the modem off, it will come on with a margin of 0.5 or 1 until I turn it off and on a few times, and then it will finally come up to 15.5 or 16.

Weird. It's almost like a car that has to warm up....

Got a computer, monitor, inkjet printer and speakers on the power strip.

is there a problem with its syncing or initialization?

I had a similar situation a while back that would cause an occasional loss of sync. There was no obvious rhyme or reason to it. I ended up getting a second dry loop installed, then I cancelled the account in question. I should note that the telco un-successfully tried a variety of fixes on the original pair including clearing it's bridged taps and swapping out a section of the pair thought to be bad. Good luck, obviously it is a line related condition...

I live just outside of Baltimore and the past few months have been problem after problem figuring it was something going on with my connection to the point where they lied to me and told me "We can't handle the fastest tier internet in your area anymore, therefore, we will have to drop your speed back to 768K." Never did happen and after all this while for the past few months, its been growing more and more of a localized upgrade all up and down the East Coast of Verizon services rather than can't handle the workload as they first made assumptions of. Tonight, I think a bug bit the switch at my local Verizon CO like a spider-man like bug where I'm getting upload speeds 3 times my normal speed. This could mean for you on a possible 7.1Mbps DSL or FIOS push in your area in the not too distant future.

Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 3360 768
Margin (dB) 14.0 10.0
Line Attenuation (dB) 46.5 31.5
Transmit Power (dBm) 16.4 11.9



As you can see my DSL speed for upload is 768 but in another post, I posted my upload speed close to 1.9Mbps and its not cached and the weird part is that my loop length is 9200ft.

If I was you, I would get a Westell 6100 modem. I dislike the 2200 because it overheats too quickly and it almost caused a fire in my house. The 6100 is more of a warm feel compared to keeping your coffee at a boil or hot when putting it on top of your 2200 modem.]]> http://www.dslreports.com/forum/remark,20403604 Tue, 29 Apr 2008 03:19:24 EDT [connectivity] Confused about slow line speeds http://www.dslreports.com/forum/remark,20397369 dsldan : Hi,

I've had DSL for a few years now on the 3.0 plan, and I've become used to rock solid speeds, except for one brief evening slowdown a while back. But for a good year or more, I've had no complaints. This is typical transceiver stats (»192.168.1.1/transtat.htm) on my Westell 2200:

Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 3360 864
Margin (db) 16.0 12.0
Line Attenuation (db) 40.0 18.5
Transmit Power (db/Hz) 13.0 11.0

Lately I've been getting slower speeds - but only in the evening.

First, I thought it was due to an oversubscribed router. But then I saw the Margin, a.k.a. (according to the modem help) Signal-to-Noise (S/N) ratio:

Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 1760 864
Margin (db) 0.5 12.0
Line Attenuation (db) 40.0 18.5
Transmit Power (db/Hz) 16.0 11.0

I've gotten slower connection speeds than this. But Margin 0.5? That's awful.

Here's what I'm confused about.....

If the problem is due to a noisy line, why does it clear up in the morning? You would think that a noisy line is a noisy line, and I would get terrible speeds all the time. Not so. In the morning, I'm back at 3360.

So why am I getting slow speeds only in the evening? Is it an oversubscribed router that is being falsely reported by the modem as a bad margin, or is it really a noisy line? If it's a noisy line, then why is it noisy only in the evening? I pick up the phone, dial 1, and... silence, no noise....

I'm confused....

loop length 8215 - 8215/250=32.86, so Line Attenuation 40 is ballpark.

Live in appt. building, can't get any closer to entry point.
Appt. has old style screw and post NID coming off the riser from the basement. NID has 3 extensions built into the wall when appt. was constructed (BRGY wire). The modem is on its own extension. Jack to modem is 10 feet of cat5e cable, made it myself. 2 phones on other 2 extensions have filters. No changes to physical setup for as long as I've had DSL.

---------------------------

edit: and just this morning, a few hours later, I turn off and turn on the modem, and I get this:

Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 3360 864
Margin (db) 19.0 12.0
Line Attenuation (db) 40.0 18.5
Transmit Power (db/Hz) 13.0 11.0

Margin 19 is pretty good. Line tests at 2864 / 732 usable speed.

So why am I getting 0.5 a few hours earlier? Why is the margin bopping around all over the place? It makes no sense, unless it's a symptom of something else besides a noisy line... and if it's a noisy line, why isn't it noisy all the time?

Any ideas?

Thanks in advance...

-------------------------------------------------------

And here we go again, after staying at 3.0 all day, margin 16, I turn it on at 1:45 AM, and ...

Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 1696 864
