Nope. All of the lights stay green. Problem is not the router either because I have tested this when the modem is directly connected to a computer. If that picture is the NID, then I did not see any type of obvious splitter or filtering device but there must be one since the modem won't connect anywhere else on the same line.]]> http://www.dslreports.com/forum/remark,20420085 Fri, 02 May 2008 08:47:25 EDT Re: DSL disconnecting after speed upgrade http://www.dslreports.com/forum/remark,20419574 David : Actually I didn't get a good look at that pic. That looks like it's just a jack. but that wire is just common flat wire or as least that's what it looks like from here.

where you took that pic is the NID, or MPOE

is maybe the ethernet light going out when it goes out all of the sudden?

It was installed by an electrician. As I said previously in this thread, I have used 3 modems and all have had the same problem.

Could someone here perhaps tell me how and where I might remove the filter that is filtering all of the other phone lines so that I can connect this modem elsewhere? I'm not sure what exactly the NID is or how I would go about removing the filter.]]> http://www.dslreports.com/forum/remark,20419184 Thu, 01 May 2008 23:37:05 EDT Re: DSL disconnecting after speed upgrade http://www.dslreports.com/forum/remark,20419033 David : Sorry for the long reply I have been rather busy tracking down larger problems. Signal looks rather strong for the problems to be happening. In the pic in the direct forum you have the dsl line plugged into a filter, I don't think it's supposed to be plugged in that way unless it's an alarm filter. Even then that asks questions. If that doesn't cure it I think you might need either a nid/sni splitter or a different modem. I would try the different modem first to eliminate that. But that filter if that's where the DSL line is going into is probably your biggest culprit so far from what I see.

I'm about ready to give up on this. This place is simply too large to pinpoint the problem to a dimmer or breaker for that matter. There are about 40 breakers and with the types of disconnects I'm getting, it seems near impossible to narrow it down to one.

I had the dsl phone line going through the surge protector (where all of these things are plugged in). Near that surge protector I was picking up a ton of static so I just plugged the modem directly into the phone line. Hopefully this solves the problem but somehow I have a feeling it won't.

Also, can anyone comment on how effective RFI filters are? Would the following link be the correct thing to buy? It doesn't mention use for phone lines and I don't want to get something that will filter the dsl data. »www.radioshack.com/product/index···cp=&sr=1

The radio will certainly help. To check the monitor, turn it off, does the static on the radio decrease? If so maybe it is contributing to the problem. Check for lighting like halogen, and dimmer switches. When the problem presents itself are the lights on. What electric devices are on when this problem occurs.

In this forum we have heard of the neighbors outdoor garage light, apartments with treadmills even I believe we had a noisy meter on the wall. It can be many different things, the trick is to narrow down the sources and being aware of what is going on around you.]]> http://www.dslreports.com/forum/remark,20306867 Wed, 09 Apr 2008 08:33:51 EDT Re: DSL disconnecting after speed upgrade http://www.dslreports.com/forum/remark,20306092 anon : Do you have your modem close to your monitor?

At this point, it has to be interference. I actually took the time today to dig through my stuff to find an old AM radio. As soon as I walked into the closet with the modem, I heard some serious static, especially when placing it near where the modem was located. It looks like the culprit for these connection problems could be some major interference. For now I have moved the modem up a few shelves in that closet and if the problems persists, I plan on moving it to a completely different room.

The FAQ mentions that a TV with a 3 prong cord can cause interference.. would a CRT monitor with a 3 prong cord be in that same category? I have a CRT monitor less than a foot away from the modem box.]]> http://www.dslreports.com/forum/remark,20306008 Tue, 08 Apr 2008 23:58:34 EDT Re: DSL disconnecting after speed upgrade http://www.dslreports.com/forum/remark,20248035 thenoob : The source of the problem turned out to be corrosion on the line.

How can I detect interference with an AM Radio?

Usually though people just turn off devices until they kill the interference. You can see the interference using info from the tech readout when you are having problems. It is a good step to be able identify the problem when these events occur, or rather know what is causing the event. RFI may not be the problem but it is a common source of seemingly intermittent disconnect problems. Over the years we have seen some doozy sources. It is not easy to find. ]]> http://www.dslreports.com/forum/remark,20238119 Thu, 27 Mar 2008 21:17:54 EDT Re: DSL disconnecting after speed upgrade http://www.dslreports.com/forum/remark,20237806 thenoob :

Hmm. The RFI looks interesting. Is there any way to test this out other than just unplugging the dimmer and waiting for it to disconnect or should I just leave this up the the at&t tech?

It would tell us if it's a synch event or a PPPoE event causing your issue.

If it automatically reconnects with the D-Link but not with the Speedstream, it sounds as though it might be a PPPoE drop. Your stats are hot with no data errors, nothing to indicate a line issue. And since it's something that doesn't seem to happen all the time, a guy coming out would more than likely not see anything and then be on his way.]]> http://www.dslreports.com/forum/remark,20233874 Thu, 27 Mar 2008 11:02:21 EDT Re: DSL disconnecting after speed upgrade http://www.dslreports.com/forum/remark,20230996 thenoob : I'm not at home much during the day, so I don't use it that much, but the disconnects seem more prominent at night. I called at&t once again and they are sending someone out to check the line (fingers crossed that that's the problem). In the mean time, they said to call next time it disconnects so that they can run some tests. For some reason, when I am using the dlink modem, I get reconnected automatically but with the speedstream, I have to manually reset the modem to get a connection. All the lights are green when it gets disconnected, so synchronization is ok.

As for interference, the only other device I have on the line is a fax machine and it does in fact have a filter on it. The modem is in a closet with a bunch of other electronic devices and wiring, but this is how it has always been and these disconnects just started happening when I upgraded the speed.]]> http://www.dslreports.com/forum/remark,20230996 Wed, 26 Mar 2008 20:17:00 EDT Re: DSL disconnecting after speed upgrade http://www.dslreports.com/forum/remark,20230877 Flippant : Your line stats look pretty good, certainly they should hold sync fine. It would be good to see them when you have a disconnection if the DS portion remains connected to see if they degrade at that time.

Thinking ahead do the disconnects occur at a specific time or around some event? Are you sure all the phone devices in your house have filters on them? Sometimes another electronic device can cause connection problems. Things like light switches (dimmers), halogen lamps and quite a few other things . So is there a specific time of day that the disconnects occur?]]> http://www.dslreports.com/forum/remark,20230877 Wed, 26 Mar 2008 19:53:24 EDT Re: DSL disconnecting after speed upgrade http://www.dslreports.com/forum/remark,20229997 anon : Ok, I am attaching my stats page as a pdf.

If your stats are poor you will disconnect alot and not much can be done without the signal being stronger/more stable. If the stats are good it means something else is causing the problem and we can give you information on what to look for.

For the 5100b this »Ameritech - SBC FAQ »Where are the Line Stats in a 5100b or 4100? can guide you to what to look for.

In fact the person from tier 2 assured me that the problem had been fixed.

Here's the problem I am having. After a speed upgrade a few weeks ago, I have been constantly losing my connection. The first support person I talked to told me to get a new modem.. long story short, the new modem I ordered didn't work either. Next, I talked to a few more tier 1 reps and tried their worthless suggestions. When I got a hold of someone from tier 2, she immediately said she saw a problem on my account. Apparently the speed upgrade had caused my static ips to be changed (seems strange I would be able to connect at all if this was the problem). She spent about an hour changing them all back and assured me my connection would work fine from here. Lo and behold! The next day I am yet again disconnected.

At this point, I have no idea what to do. AT&T's tech support has proved so far that they cannot solve this issue.

Does anyone have any suggestions? Thanks.]]> http://www.dslreports.com/forum/remark,20226426 Wed, 26 Mar 2008 00:21:25 EDT
