Comcast internet issues since 2004 and im GETTING TIRED OF IT

First of all i have been having comcast issues since the day we moved into this House in woodbridge VA.  Was built in 99, im 34 years old and this has been going on since i was about 17-18 years old.

The internet keeps dropping, and we dont get advertised speeds for the 1 gig.   For years and years and years and years and YEARS i have had comcast people come over to the house to "fix" the problem and they all do the same thing.  Either add a signal amplifier, tell me noise is on the line and put a noise filter on, then of course blame the wiring in the house, or they blame the 1 two way splitter going to the cable modem from behind the house.  They cut the ends off the cables and replace them.. its been done so many times now the wires coming out of the house are so short they had to add a 1 way connector and add a extention to the coaxial cables just to reach the box 6 inches away..  Weve gone through countless modems, and t.v boxes as the tech just blame those as well.

Its been really bad this Month Dec 2020, ive been on the internet a total of 4-5 days without disconnects, the rest it will d/c all day long, or d/c every 30 minutes.   And it isnt just that its the X1 boxes, everytime they reset at night the t.v gets a red screen.. rkd03004 and takes hours to boot back up.   Weve had the lines in the house replaced, the box against the house is brand new eliminating the 2000s wiring mess of splitters, and putting it all on one signal amplifier.  Each room but one has its own dedicated line now.  Still the same problems.  

The comcast labs diagnostic in the x1 boxes said 1 bar outa 5 and red poor signal.  

I called YET AGAIN and YET AGAIN had a tech come out a week ago, and he discovered a signal filter on the main tap, and tossed it in the woods explanining the x1 stuff doesnt like those.  Well that was put on by a prior tech years ago to try to fix the issue i remember him saying there was noise on the tap.  Now suddenly this thing was causing low signal to the house for years ????.

The comcast labs went from 1 bar to 5 green good, and the boxes connect in 5 minutes.  Internet also connected immediatly.  I thought the issue was fixed..  Then BOOM 3 days later, the modem started d.cing again, and on wed when we had the rain/sleet/snow in Virginia the modem wouldnt connect once, it was on a red light, and i had no internet

Im sick of this, and my Patience is done, these 220-250$ bills a month are insaine for tv and internet, and there is no way to lower it either.  Yet services remain terrible.

Had a guy come a week ago and disconered a noise filter causing the poor signal on the main tap.. why wasnt this discovered over the years ive been calling about this ?  Now the t.v signals are good 5 bars, and the house signal overall is better..   HOWEVER 3 days later when it rained and sleeted on wed this week it dropped alllll day and i had no internet, yet comcast said they had no issues in my area.   It got progreessivly better as it dried out and on the 2nd day i have internet again.

This leads me to believe water is getting to the tap or the line to my house or perhaps another tap in the area is having issues and causing problems to my main tap..   I had a guy come out, but of course he came on the dry day and claims the tap is fine, although the signal is low at +10 for a tap he said, and my line going to the house he said was fine.   The signal was 6 at the house, and with the signal amplifier i had +7 at the main DVR box and -5 or -6 at the modem, mainly because its split once at the modem so thats a -3.5 loss..  Regardless its in spec

I decided to check my modems SNR and everything, and the only thing i notice is the Upstream power level seems a little low, between 37-38, nearly borderline from the 35-51 i think it should be at.  

Also most of these problems didnt start until i got these X1 boxes years ago, i replaced the 300mbps skinny modem with the black square tall box, and thats mainly when the internet started dropping every single day for years..  I replaced it a week ago with a white square modem for 2 gig internet they said.. and same thing, drop outs.   Also i dont get 1gigabit speeds, when i was paying for it i would only get around 650-700..  I pay for 600mbps now and i do get 600 but the tech today said the slow speeds on the 1gig is due to a old tap and old line going to my house.

Well if thats true, then shouldnt comcast FIX THIS !!!,  Do i need to be 40-50-60-70 years old until the problem is finally fixed?  Cant blame the house as every line, connector, and the box in the back has been replaced.  The only things that havent been touched are the 21 year old tap, and line in the ground.

SICK OF THIS !!!!!!!!!!!!!!   Please help me, whats even worse is i lost my Job in Jan, i work now, but im 408$ behind on the bill and they keep threatening to cut me off, and they have done it a few times, i can pay the bill now, just not a whopping 408$ plus the months bill.  They keep charging late fees and activation fees..  Yet i dont even get services rendered and havent for 10+ years.. its rediculous.
