CM700 dropping internet connection

did you reboot your modem? you have a lot of uncorrectables.
If you reboot, it resets it so you can go off the new settings.
here's an article that goes over signal strengths, snr, logs, etc. Its not to long but has good info and is easier than me typing it all up.
Based your response and that of FURRYe38, I called my ISP and had them check the signal strength at the modem (I guess I could have looked at the connections page on the router, but didn't know how to read the entries). Sure enough, it was weak. Traced it to a 4-way splitter in the basement that my previous homeowner had installed. Didn't need that splitter any way, so used an inline coupler and the problem seems to have gone away. I do have the connections table uploaded, but it probably shows things are mighty fine now. Would like some guidance on what to expect in Power and SNR columns for a good connection.

- Thanks. Rebooted and the uncorrectables are cleared to 0. Summer correctable errors do show up in a couple of channels, but the numbers, below 10, seem stable. Also, thanks for the article on how to read the log entries. Very useful!
