basically this is what happened.. my modem wasnt synching right and so pacbell (or sbc ?? )sent a technician.... there was the line noise on 2 of my phones that you could hear even with the filters and he and he fixed the kitchen phone by putting in a splitter ... except the noise didnt go away from my room with the dsl connection. the technician didnt care.. so whatever... i didnt care anymore.. at least the modem was synching. So .. I start up the comp and try to get online but the modem light was flashing.... oooh wow ..no synch for me! I restart a few times and take a shower to cool off.. it worked! I was online when i got back. I goto some sites and ftps yet it seemed a little slower so i do some speed tests and I was getting about 680kbps.. WHAT?? ok.. i'll be calm and do some more... 650kbps... 1110kbps.... wtf?? I was getting ~1.5mb before! I used to download at 140kilobytes a second now its at 70-65kBps! I tested it everywhere... especially microsofts ftp where it seems to give me the best results. ok now for my question
what could he have done wrong? could he have split the voice and data in half? thus halving my connection speed? and also... my sister has dsl downstairs w/ the splitter but she has a phone jack with the DATA and VOICE ... interesting...
that was a waste of time... he came to the conclusion that he didnt know anything and that the noise was coming from my modem... NO SH*T!! what else would be making it.. I turned it on and off for him 4 times so he could hear the noise turn on and off.
btw... I've tested my speed everywhere and i havent gone above my 145KB.. and please dont say crap like "oh but its better than a 56k!" =)
thank you
Can't get cable... supposedly not serviceable because my lines are on my neighbors property but I have an easement so I can go there any time I want! I own that crap too but they couldnt find where anything would go in my house... yeah my friend who lives down the street gets like 180KB average

I'm not exactly sure.. the technician didnt give me a straight answer but I'll find out later today. What would be the difference? Would that account for my speed degredation?
If you did a "self-install" on your DSL modem, most likely, you got several filters with your DSL modem, for each and every phone (not phone jacks) that you've connected. Voice and DSL signals share the same copper phone line, but they use different signal frequency ranges. You voice (therefore phone) uses the lowest 4KHz, and DSL shares the higher frequencies for Up/Down transmissions. The filters that your phones are connecting to, are for blocking out the higher DSL frequencies. The only exception is your DSL modem connection where you CAN NOT use a blocking filer.
As an option, your phone company (or ISP) may install ON-SITE, a "splitter" at where your main phone line(s) comes into your house. It actually separates DSL high frequency signal and bring it directly to a separate pair of copper wire to DSL modem.
So, the "splitting" has nothing to do with splitting your DSL speed in half. The problem you have mostlikely comes from two areas. You phone line behind the walls in your house, or to the local phone company has noise. Make sure you have UTP (unshielded twist pair, often called Cat 3 cable) copper lines in the house, and DON'T use "flat" phone extension cord from your DSL phone jack to your DSL modem. Flat copper phone extension cord WILL pick up noise and reduce the DSL speeds (up & down). Or, the ISP has overloaded DSLAM and router equipment. There is not much you can do, but keep complaining to your ISP. Hopefully, they will improve.

make sure you have new or upgraded network interface on your house,(old and corroded copper lines will efect your speed) thats where the phone lines come into your house,then run a dedicated line from box to your computer using cat5 cable.this will take care of your inside wiring problems,if your speed hasnt changed then it is your isp problem,i did the above and helped quite a bit.

a few more facts would help me reply. ie. you said you were getting 1.5 Mbps then you were only getting 650?Kbps. first, what did you sign up for? 1.5Mbps or their 768kbps? keep in mind there is overhead built into that. You may have been provisioned for the higher one by mistake. you also talked about download speeds. dont confuse the two! won't be the same. YOu also did not state what kind of computor you had. ie. processor speed, RAM. ALSO, are your phone lines daisy chained (connected from jack to jack) or home run (each jack with its own wire to the NID? and you said your sister has DSL... own service on her own line or coming in as one service on one phone line? so are you two sharing and downloading at the same time... that would slow you down. (did you get a router or multiple NIC's, is one PC a server or indivivual NIC's and just plug into the same line with the same phone number?) now let me set a few things straight. YES, the line filter (Z-Blocker) will let the low frequencies pass. (low pass filter). so no DSL connection can be made with this on the line, but you'll be able to use the phone. The splitter does NOT act as a high pass filter and allow only the DSL to go to your modem as someone stated. the Splitter is installed at your NID. where the regulated and unregulated wires meet. the jack used to connect your modem to MUST be home run to the NID with CAT 3 or CAT5 (CAT5 not needed) to eliminate questionable IW to your jack and throughout your residence. your IW (interior wire) for this modem jack is connected to the binding posts in the NID directly, along with the pigtails from the splitter. then all the other IW's will be connected to the binding posts on the splitter. dont forget your sisters jack will need a home-run wire connected to the binding posts, same as your IW so then it won't matter if all other jacks are daisy chained or not, nor will it matter what kind of wire is used. Quad wire is also bad, (red/green and yellow/black). so you will get DSL and VOICE at your dsl jack and all other jacks will be VOICE only.
ALSO, things that can add noise.. off the top of my head, phones, cordless phones, modems (sisters computor), fluorescent lights, (keep your IW away from these, if you must cross them with your IW go perpendicular to the light bulbs), improperly gounded systems, including your phone network anything else in your house or in your neighbor hood (if it's heavy machinery stuff). bad phone wire on the regulated side. they can do a stress test on your phone network.
i suspect you are misinformed on data download speeds and your dsl speed that everyone talks about. i use the speed tests from DSLREPORTS.COM and COMPUTINGCENTRAL.COM
also, i hope you didn't get an inexperiened tech from SBC. he can test your line for what your line is capable of (4000Kbps! maybe) and if your line is marginal. if it isn't right, the regulated techs from SBC will have to come out and do their tests on the regulated lines, (from the CO to your NID) and more than likely, if it fails, you have a bad drop wire or a slight ground on your wires somewhere. this would more than likely make you lose your connection vs just giving you a slower speed
i think all your problems will be resolved if you home run your jack with CAT 3 and make sure you have that splitter installed correctly.
Or....he could have a load coil still on the line someplace. Or....they may need to cut his field pair down at his serving terminal to the field. Excess lengths of extra wire on his pair especially if he is on a cable that goes 5 miles on down the line past his serving terminal of runs in multiples to other boxes can introduce noise or shallow moisture induced tip grounds etc, ring grounds, all sort a crap as you other phone dsl techies know. Cut the pair to the field on a DSL install and make sure it's not loaded someplace. Its not hard to miss a load coil now and then. If his stuff is airborne, as you know the street lights can introduce noise as can electrical wires. Best thing is to test pair integrity, balance, and get the extra length off the pair on the field side. Get a properly installed splitter in the NID and dedicate one jack just to the modem. Toss the dongle filters in the trash. But if you must use those damn things, make sure you plug them into the wall jack, not the phone end. Makes em back asswards otherwise.
