Hi. I'm having a problem with my ADSL Internet where my connection will suddenly disconnect at random for no reason. I've recently moved to a new house. In my old house my Internet was working perfectly fine. So I know for a fact that my equipment, (MODEM/Router, ADSL filters, cables, etc.) are all working fine. Anyway, I moved to a new house. The new house had no telephone line, (the previous occupant had removed the phone line for some reason.) So I contacted Telkom to come and install a phone line in the new house. I had to wait more than a month for them to finally come and install the phone line at the new house. Once that was done I finally got my Internet up and running and everything was working fine for the first 5 days. Then suddenly today I started experiencing intermittent disconnections with my ADSL Internet. I went into my MODEM's settings and took a look at the line stats and it seems there is a lot of noise on my line. Here are my line stats:
"Line Attenuation": (Downstream = 43.0 db / Upstream = 23.6 db)
"Noise Margin": (Downstream = 5.8 db / Upstream = 12.6 db)
(*NOTE: Sometimes the Downstream Noise Margin drops to as low as 3.0 db)
To my knowledge the higher the number of the Noise Margin the better, and anything below 11.0 db for Noise Margin is considered bad. I would really appreciate it if you guys (Telkom) could look into this ASAP. I've sent you all my details via PM.
I'm on 4 mbps Telkom ADSL Internet. The connection speed is as follows:
Downstream = 4096 kbps / Upstream = 512 kbps
The MODEM I am using is a NETGEAR N300 Wireless ADSL2+ Modem Router (DGN2200). It is a MODEM that I purchased directly from Telkom.
Here is an article I found explaining noise margin:

As you can see, it seems there is a lot of noise on my line for some reason, and this is interfering with my ADSL Internet. Please let me know what I need to do to fix this ASAP.
For the love of all that is holy please do not tell me to phone Telkom's support line. The last time I phoned them they put me on hold for over 2 hours before I got through and the technician they sent never even showed up. I'd rather burn my own eyes out then go through that again.
