Previously I had an SNR Margin of 18db and since two days ago, it has dropped significantly, from 18 to around 9~12db!
I had an issue with the specified speed, and called my ISP, they checked my line and it was OK, then they said, we need to check the center.
After that I noticed my SNR Margin has dropped significantly!
Before:
After:
The CRC has also increased significantly compared to before which IMHO means there are many requests failing because of either noise or something else caused by this.
I need to say this as well, on 12Mb, this is how my connection stats looked like :
Backstory :
My issue with ISP was I couldn't achieve the specified speed. It used to be fine but then lately I noticed my 16Mb connection, cant even download more than 1.2~1.3MB/s! meaning the speed was actually around 9~10Mbs. In my 8Mb, I could only achieve 500KB~920KB/s which was not OK, I had to get constantly 1MB/s or around that number. In order to fix this temporarily they set my 8Mb connection to 12Mb and that's the screenshot you see above. After 3 weeks of going back and forth they finally came and checked my Line, my line was OK, and they said they need to check their equipment and this happened. now my like is struggling with the 8Mb connection!
update this is the speedtest.net results I just got!:
I need to know what could have caused this so I can talk to the ISP agents prepared, they have the tendency to deceive people if they know the other person has little/no knowledge concerning the matter at hand.
