I've been having intermittent lag spikes throughout the day and I've been talking to Cox about getting it fixed. there have been multiple outages and maintenance work done since I got Cox involved and the work has been going on for months. I check and my modem levels have changed. I'm wondering if these numbers are good.
I would say they are decent but not perfect. Your downstream power level could be a little higher but your SNR is strong and your upstream is good. There are are some uncorrectables on the OFDM but nothing major. What do your logs say?
