Why don't you call your internet provider and ask them to replace the dsl modem or check your connection?
AT&T and Time Warner both gave me a replacement modem free.

as far as the internal wiring thing (which i assume means in my house)... chances are it's fine if it's been working for years fairly well up until recently, right? (because it's basically been sitting there the same way for years now) ; but i guess it can't hurt to have them run a basic check on it and then go from there.
but when you call them and tell them you think the DSL modem is going (like can't keep a stable connection for any length of time) i assume they can run a quick test on their end and determine if it's their line and if it's not is it pretty safe to assume my DSL modem is going out?
also, i noticed this in my DSL modem statistics... SN Margin (dB) is generally in the 11-14db range (it's even raining a bit outside to at the moment) as i assume that's a decent signal according to what i found online which i posted below...
taking a quick look online i see this for the db levels...
6dB or below is bad and will experience no synch or intermittent synch problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with no synch problems
20dB-28dB is excellent
29dB or above is outstanding
EDIT: i was just refreshing the page some more and i seen it hit as low as 7db. but i imagine it's generally in the 11range or a bit better. so lets just say it drops connection to where the DSL modem is having issues syncing... ain't that when the general RED DSL light starts flashing meaning it can't sync as i still have a green light on modem. (because even when the light is solid green like normal it has issues keeping a stable connection when in the past it seemed to only act up when you got the obvious flashing RED DSL light in which case it's normal at that point for the internet not to work)

Ive personally used Asus adsl modem/routers for the last few years, with great personal results. Customers looking for cheap cheerful yet functional, ive pointed to TP-Link products.
It could also be a "dry joint" in your PSTN line outside, if its worse in rainy or wet weather then that's a good root cause also.

Well i finally called AT&T earlier today (Monday) and to sum it up they are going to send out someone to check the lines on Wednesday as i told the guy on the phone that i tried two different DSL modems and changed around DSL filters and that my SNR Margin i see drops off when the line acts up etc and then he put me on hold while they ran a check on my line and they came back saying the line was acting up (like they found a line error) about once every 30minutes (they must have something in place that monitors line connection over a period of time) which plays inline with my general experiences as sometimes it's even worse (like acts up more than once every 30minutes) than that and sometimes it's better (like might go maybe a few hours without too much issues).
but they asked what modem and model i had and i told them i originally had the Speedstream 4100 but currently had the "TP-LINK TD-8616" in place and they did not complain about it as from what i seen online they apparently don't support it.
but i imagine the equipment they use hopefully can narrow down this issue and get it fixed as it would be great just to have a stable connection again that stays connected with only occasional disconnects like it was a while back but hopefully after they fix the line it will be more reliable like Cable internet is which that rarely went down when i used to have it back in the years 2000-2005. because my DSL even before these recent major issues was still clearly not as reliable as Cable was in my experience but it was not to the point it was a big issue though either.
but anyways... ill make another post (probably sometime on Thursday) after they send out the repair person and use the internet for about 12-24hours as i figure if it don't act up in that time frame odds are it's fixed.
p.s. side note: i received my DSL filters (3 of em) today so i got those just in case i have issues down the road but i probably won't even need them since chances are all of my old DSL filters, which i had since Nov 2006, are still working good enough.

well here is a bit of a update as it took me a while to post this message due to the Neowin website being down for a while and just got back from out of state. but anyways...
after they attempted to fix it, it's not 100percent fixed but it did get quite a bit better. so in short... it's up to a standard i can easily live with, so far as the disconnections are generally at a minimum. only a couple disconnections per day tops based on the couple days of testing on it, so far.
but basically the AT&T guy said that the house's phone wiring is pretty much shot (i believe him to) as there is a short in the wiring somewhere but since coming into the house would get expensive (said $100 initial charge and then basically $100 per hour after that) he did what he could without charging us (i think he even did a bit more than some other guys would have to. he was cool about it all.) as he somewhat re-wired the DSL line a bit differently (like we can only use the DSL line itself on the phone jack it's currently on) and it was floating in the 2000-2300kbps area at the phone jack in the house and now, after his slight re-wiring, it's in the 3000-3500kbps area to the phone jack connected to the DSL modem. even at the main house jack (the one that's just before it's routed into the house) it's max is a bit over 5000kbps. so that 5000kbps is the theoretical maximum i could get even with perfect lines and i imagine by the time you wire into your house, even with good wiring, you would probably lose some of that speed. either way, it won't matter currently because i only have 1536kbps connect speed as what's currently to the DSL modem is already exceeding the allowed speed anyways.
he was also saying that with DSL you can have it drop to 1000kbps or so at the phone jack connected to the DSL modem and it will most likely stay connected but once you start having it drop to 500-700kbps area then it can start having connection issues.
but basically i have about another 1000kbps stronger connection (like the low 3000's(after re-wire) vs low 2000's kbps(initially before re-wire)) which my theory is being i got a stronger connection, even though the short (which explains whether related issues with increased moisture etc) is still there, it probably needs to short harder to actually drop the connection and, at least so far, it's been mostly stable now as it kicked out 5am on June 19th and then once in the 3pm area on the 20th of June. i was gone for most of June 21st-June 23rd as it's late the 23rd now so i did not see how it did over the last couple of days now.
also, the connection SNR Margin in the DSL modem itself is generally better (when it's at it's best it's 20-ish db where as before at it's best it might have been 17 or so) and i been monitoring it here and there and you can see it drop down like 10-14db, sometimes even a bit less, but luckily it don't stay that way (like below 10db or so) for too long and jumps back up which seems to further suggest my theory is probably right being that it's still shorting like it was before but being i got a stronger connection to begin with it's got to short harder in order to break the connection (i.e. lose internet) which probably explains those couple of disconnects over the first day or two after AT&T doing their slight tweak. because he was saying what he was doing may or may not fix it but he said he felt it had a reasonable change to work otherwise he would have not wasted his time on it as the guy said he was working for AT&T for 17 years or so if i recall correctly.
but if it stays roughly at that rate i should be good enough for now but i still want to test it longer to see how it holds up during rain/thunderstorms as i figure by the time i get through this summer with higher humidity etc that should be a good test to see how my line will be for a while. but it does make you wonder if the line will eventually deteriorate even further down the road and eventually hit a point to where you will be forced to re-wire the house's phone wiring otherwise you will get no DSL/no landline phone.
p.s. he was even saying the phone line, with the phone itself, is teetering between working and not working. but so far it's not really gave us issues on the phone side of things so it might be just barely stable enough to keep on working as far as the regular phone goes.
side note: at the time i type this the DSL SNR Margin is generally in the 12-14db area and it was pretty hot (nearly 90f outside) and basically humid today.
