Today our network is having slow internet connection. Our ping rate to the local server is 48. So pages have a long lag before they open. Speed rates are fine once there, but the lag is the problem. How to troubleshoot? I've enclosed a section of our connection log. Thanks for helping.
The upstream power is high and it may be intermittently fluctuating even higher to out of spec levels. The downstream power is weak / out of spec on many channels as well. And the SNR is too low / out of spec on channel 33. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, and latency problems.
In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
Thanks. This just happened. Could it be caused by dampness in the system? It's been wet here until just a few days ago. Our line comes from the street and from side of house into basement. Then splits to several rooms, plus a long ethernet connection via underground pipe to our barn where it feeds the modem. So lots of connections but all needed. Yesterday the connection was fine. All connections done years ago by Comcast service team.

Thanks so much. I will follow this for a few days and see if sunlight fixes things. FYI I was having some networking issues re my vpn and yesterday I rebooted my modem.
This morning, first thing I did this:
1 Uninstalled WAN Miniport drivers (IKEv2, IP, IPv6, etc) and reinstalled them. 2. netsh int ip reset, netsh int ipv6 reset, netsh winsock reset. Then restarted my PC.
I did not try the internet before I did this so don't know if the ping problem was there before.
Could any of that have made this problem arise?
None of that can affect the signals / connection quality with the Comcast system.
Thanks. You as well !
FWIW, that can't affect the power levels either. Noting on the LAN side can.
