The infamous 100/20 VDSL2 Lines balancing act; 3 tech visits different sync rates each time(posted below):

Hi All,

I've been trying to get my lines working right for a few weeks now. I've reached a point where local tech's are losing control/power on the issue as it seems to be an under lying issue within the network from the corporate office as I've been told. I've sent an informal complaint to the FCC so I've been in touch with the office of the president in efforts to fix the issue.  Especially as I'm hoping to get access to fiber eventually once made available for FTTP and I wouldn't want this outside line issue that is effecting all my neighbors on 100/20 as well to also be an issue in higher tier speeds. Which the person I am speaking with from OOP is very nice I'm afraid their actual knowledge of difference between speed qualities are lacking, so this issue may not be resolved unless I can get some proper guidance.

Little backstory: installed on a move service mid october no real issues just inconsistent speed tests. Originally my connection started to disconnect so we had a tech come out to service and these were the numbers and this was from first week of January:

 

And here's how the numbers were altered where most errors went away, lines were balanced a little closer after the 2nd tech came(1st tech just called from the box saying everything was ok and it wasn't) This tech explained a problem of the two sources of line coming from outside because these speeds shouldn't be under 40-70mbs on a single line test when the FTTN box is only 200 feet away:


Finally here is after the last tech came just last night, numbers changed slightly errors seem to have gone down further but the balance was further off. Knowing that this is some what "to spec" been told to have SELT tests ran but no tech has actually done so yet. My main issue I'm trying to resolve here is to achieve atleast 20% of the 100/mbs which it's not as I said at times it's under 40 and that is hard wired in on cat6:

Main question(s): Will FTTP connections be effected by this outside line issue? And is it even possible to achieve within 20% range as promised in my contract or am I just wasting my time with this outdated technology? As tmobile 4g LGE towers are within full strength within my location, and they offer home internet, and I can get 110 single line test from them down as it seems like the speed option with the most integrity in the area currently. So I'm strongly considering this route as it is the most competitive option available. That is if ATT's 100/20 is not achievable on a single line test within the range of 20%. Please advise and let me know if you need anymore screenshots; speed tests, pings, traceroutes, or etc. I truly hope to be able resolve this and keep ATT as my main home internet provider. Thanks in advance

Best,

I use MRTG to gather and graph history.  I have PowerShell scripts launched by MRTG to get the data from the gateway and reformat it to MRTG's liking.  This is raw line capacity, my max user line is way below that green one. As long as that green line doesn't drop below 40 Mbps, my service will not be affected, so I'm not going to waste good will trying to drag a tech out to work on it.

One of these days I might upgrade to 100 Mbps, then I might get worried if one of the dual pair dropped as low at 65 Mbps.

Hey All!

More updates: So I tried some more troubleshooting with the new router I was sent a week ago since it started giving me some unfavorable numbers coming out of the gateway as well as the smart home manager speed test not working I was getting these kind of low numbers below on the download with a bit of latency on uploads :

So I attempted to flush the issue by swapping back to my original modem and noticed my downsync speeds went back to normal while my latency in upload was still present:


As a last ditch attempt to avoid having another tech come to tell me what I could already figure out on my own so this case can be closed with the office of the president and the FCC on time without an extension, I swapped back to the new modem which forced a reset and now my numbers are looking way better all around.
Here's what my smart home manager is reading(now working after reset, before was getting an error after swap) with the new modem consistent everytime now:
I spoke with the office of the president to let them know this fix may have resolved the issue so we can potentially close it mark resolved and we can all move on with our lives we agreed I will monitor it for a few more days and send updates.
.
.
Can someone confirm if fluctuation in latency in uploads like this is normal and or if they've seen cases of routers that had been repurposed from moves of different tier systems(1000 fiber to 100/20) where they retain some kind of artifactual data someway or another that causes latency in the lines especially on uploads is it normal to see some latency in uploads time to time even when download shows very low latency?  Because I notice now with the new modem all artifacting issues from the modem cleared my uploads aren't doing a weird jitter thing and downloads are consistent while Latency is with in a much more favorable range as it should be now. While I also notice when ever I get the slightest latency in my uploads I see FEC errors on line1 appear instantly.

FYI: Not sure if I'm going to keep the thread going with this post or start a new one about all the photos i've taken documenting the neighborhood setups with vrads and aerial fiber splitters and other alien looking things in the poles to show how close my area is to gaining full fiber network access. Always open to suggestions. Thanks!
