twdsm.rate_net_ds = 1008;

Forgot to add, the upstream SNR is at 15 and you have a 512K upstream speed profile.

You have room for faster speed on the upstream.

So jump in the direct forum »Bell Canada Direct and tell them to give you what you are paying for and increase the upstream speed (unless of course if this SNR value of the upstream is jumping all over, which you can check yourself as said in the other post).
