DSL Connection Stability


I live in a area that forces me to use Verizon DSL. I also have a 3 month old Actiontec GT784WNV modem. When it is connected I get between 6 and 7 Mbps which is fine. The problem I am having is I get disconnected many times throughout the day. I have recently done a few things on my end to help this. First I ran a shielded cat 5 twisted pair cable directly from the modem to the Verizon NID in the garage. Next I put ferrit chokes on all the power cables associated with my network. This has improved things but I still get disconnected. When checking the gateway status of the modem is says I have a SNR downstream of 8 db and upstream of 9 db. everything I read says anything below 10 SNR will cause problems. All other parameters seem to be within acceptable limits. Verizon says they have tested their lines and equipment and everything checks out. I’m not looking for more speed but I am looking to be able to stream Netflix or Hulu without going into the other room and re setting the modem a few times during the program. I also have a D-Link 2750B modem that I have swapped out to make sure it wasn’t a modem issue but that actually made things worse.
I am trying to do everything I can on my end to maximize the DSL signal. I want to have all my ducks in a row before I contact Verizon again. Any other suggestions?
