High Latency / Spikes
Been having constant latency spike issues for the past month, but more so these last 2 weeks going throughout the whole day. Calling the support line just has me waiting on hold for them to reboot my modem or tighten the cables which I've done.
I am hard wired and have no other real devices other than a phone on the same network.
Imgur link to the down/upstream information, we are on a TG1682G gateway -
Any input would be great.

There is a low to out of spec SNR on channels 16 through 18, and channel 15 is not even being locked on to. Noise ingressing into the line(s) somewhere at that frequency range can cause that. First, try power-cycling the modem again to see if it will lock on to a different set of perhaps cleaner channels.
If there is still no joy, try some of these self troubleshooting tips;
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.
Good luck !
