friend.evil wroteI found a solution today and took me 10 hours of work, so the elevator is only PART of the problem, what I noticed is the internet was extremely slow and disconnecting more at night, and working again in the Morning.
I went downstairs at 6am to check why and saw the Guard Opening the Door in the Garage and turning off the 4 lights in the Garage, the second he turned the off the lights, the connection was working perfectly and SNR Margin went up from 6 to 15, this will be hard to explain but will try, the elevator turns the SNR Margin down from 15 to 9 when activated but the connection is still working perfectly, only at night when he turns on the Lights the SNR Margin drops to 6 and when the elevator is on, the connection drops completely and then recalibrates at 1.8Mbps Download Speed instead of 4Mbps and stays this way the whole night.
What I did is look how the lights were wired and there was a faulty cable causing noise and issues, replacing it was hard so we moved the faulty cable away from the phone box, the phone box is at the top so we moved the faulty cable to the bottom, now the SNR Margin only drops to 10.4 when the lights are on and no more disconnections when the elevator is working. I have 2 connections to my house from Ogero, 1st one is receiving 4Mbps (up to 6Mbps) and 2nd one is receiving 2.6Mbps (calling tomorrow to change the location in the phone box because now its from their side) when elevator and lights are on, so anyone having issues needs to turn off each conductor one at a time to see which is causing a conflict and move it aside, this will help the SNR Margin stay in the safe side if the elevator is on.
Good Job man, the thing is in my building the elevator is the main and only problem.
Yesterday ogero came and moved my reference to another building next to mine for testing and no problem happened there.
Today they will come and move the phone box outside the electricity room to check.
