att dsl running at speeds of 384kps..

This is my first thread so to bluntly explain my situation(like most others):

-----------------------------------------------------------
From what I have read and can tell by just examining my connection, i should have a default connection of anywhere between 384kps-1696kps(default)..

My only complaint to this connection is: why am I at the lowest possible speed?(42kb/s)

Just to say:
I have had internet services with att before at my other home no less than a month ago(10/2008) and with a speed of 1700-1900kps. When we transferred the account over the the new home we just got 384(no matter what i have tried)
----------------------------------------------------------
My attempts:

I have tried disconnecting all phone devices and attempting to run the computer alone with the dsl modem.

I have unplugged every and any microwaves/highly charge electrical objects in my house(very few).

I have tried using my previous modem(SpeedStream 4100) in attempts to test weather or not my new 2wire is to blame or not(i don't believe its at fault :: my old device is suffering from the same lack in speed 'identical').
----------------------------------------------------------
My suspicions(going from "least" concerns to "most" concern):

1.Although the house is roughly new, i do not know for certain if there is any crossovers or splices between any wires in the walls(electrical vs phone lines).

2.the house has a second floor and three bathrooms...could vibrations from pipelines be a problem.

3.Third and most importantly..... after moving here for one week i have notice that in front of the house there is a cable on top of our cherry tree. It looks like some kind of electrical cable that has snaped during the last few days of storms...(seems like the governments going to have to get involved...)

Question:
Who do i contact to repair an electrical line that has disconnected and fallen? SMUD? or ATT? or (some other government agency?)

Your speeds are so low because your attenuation is excessively high (Downstream Atten. at 300kHz: 65.7 dB).

So either there is a problem with your loop, your loop is too long, or there is a serious inside wiring problem. Try to eliminate the latter possibility first by re-testing your attenuation and stats at your NID: »AT&T Southeast Forum FAQ »How to check modem stats, synch rates & speeds from test jack at the NID.

Ok i have read the info and have connected the dsl 2wire modem directly to the customer test line outside of the house.

it has a result of:

Now my "Excessive Impulse Noise" problem looks ok but i am still getting very slow speeds. 384kb.

If anyone knows the next procedure in resolving my problem please tell me.

Your speed is capped. Probably when your DSL started, your line failed the speed ramp due to poor internal wiring and "stuck" at 384. Those "Max" numbers are maxrates the line can handle, so you see that your loop can easily handle 1536 at your NID, but not at your phone jack.

Yes, I realize that the first set of maxrates exceeded 1536, but may not be high enough to have a stable line, especially with those excessive impulse noise tones.

The techs in AT&T Direct: »AT&T Direct can raise your sync speeds to the full 1536 once your line has a max rate that would support those speeds. You would probably need work on your inside wiring or a home run-POTS splitter installed to get to that point. You can install the home run yourself or pay an AT&T tech to do it.

Post a Trouble thread in Direct and ask the tech what speeds your loop can handle now and about a home run if you need one. Your line may be able to handle 768/384 speeds without doing anything to it.

ok after doing a line test outside of the house and "returning" the network back inside.. i have established this stats:(inside stats)

Don't know what happened but after testing the line directly and returning it to its original place the connection seems to have less noise now. Also sometimes the suspicious noise would completely disappear.

I am now going to post a request for faster speed sync on the forum for sbc direct.

Just be aware that those previous noise levels may return. It isn't uncommon for impulse noise levels to vary from day to day, from day to night, and even from hour to hour.

Well its been about two weeks now since the testing, Ive been kinda busy with other stuff, but back to the speed.

I've been keeping track of the niose level(previous):

Impulse Noise Comp. Tones: 44 Suspicious - impulse noise detected

and the new and (greatfully) steady and always result is:

Impulse Noise Comp. Tones: 0 Ok

YAY!

But the speed is still low.
I have inform att over the phone and will get a tech checkup tomarrow again...

also I left a post at the att direct forum for a speed sync check.

Hopefully ill get some news update that will resolve my problems.

-----------------------------------------------------------
AND no i am not going to pay another nickle for an upgrade until i get atleast 1500kps for current rate....

also todays stats(max rates alters from 1500-2400 randomly some days)

EDITED!!

Ugh, the customer service tech that visited my home told me that this is all that i could get and that "if only" there was a local rt would I be able to establish a stronger line...

unfortunatly there isnt one.. 384kps is my limit...
I am very unhappy about this..
I have always enjoyed att's efficient budget and decent connection at my other home..
however we cannot host 4 computer and two entertain systems(ps3/wii) with a connection of 384kps.
thank you for your updates dl
