| [Connectivity] Zoom 5341J signal levels I recently upgraded my SB5120 modem to a Zoom 5341J modem. How do these signals look? One thing I've noticed with this new modem is that the blue US light would change from solid to constantly blinking every few days. There aren't any noticeable connection issues when this happens, but is this something common with this modem?

| Your signal levels are not balanced properly. From channel to channel you have too much variation. Your Upstream is below recommended.
Call Comcast.

Others have reported the blinking upstream light before. I don't remember if there is any official reason as to what it means.
That said, your upstream is unusually low. I guess if it works, it's OK. |
