Re: [TWC] Modem Problem? Motorola calls for a downstream to be between -15 and +15.
With a 12db atten, you may have killed a separate issue affecting your service, not to +11db downstream level itself.
Yeah +11 is barely out of range. +15 well out of tolerable range and problematic. Your signals aren't great but they shouldn't be causing the issue.
