Downstream data on your modem should read 4096 kbps

You're right about the attenuation... but as for the SNR, the minimum required for 4 Mbps is only 20db... But if your line holds steady, then good for you!

What the installer said is kinda true... although your port would have already been set for 4 Mbps before he came, the system needs 24 hours after he 'activates' it to register the changes and give you your speed...
