I would explore the reasons for all of those uncorrectables. If your uncorrectables are constantly increasing that's a problem on the downstream. Every now and then you might see a momentary burst of uncorrectables due to maintenance on the line or whatever. But if you're getting uncorrectables on a regular basis it's going to cause connection problems because that represents lost packets and lost data. For comparison I've had a total of about 20 uncorrectables in the past 2 months. You are showing over 100,000 since whenever your modem was last rebooted.
