Ok, I'm so done with that problem and I need to ask 2 questions(maybe dumb), hope some experts here have answers...
First one :
That's the copper wire cable in my house, is that thing in the picture considered bad? I mean does that extra length have any influence on the quality of the DSL connection, attenuation maybe?
Second one :
See that cable coming from bottom right corner? that's the copper wire cable coming from my house, it ends at the top of that wooden pole, and those large cables are electricity cables, is it in proximity of electrical interference? can that actually cause noise and result in high amount of CRC?
please keep in mind I was getting 0 CRC all the time before my line got upgraded to 4Mbps from 1Mbps
