Gigabit internet drops speeds and fluctuates

Hello,
I have been having an issue with my gigabit internet. My connection keeps dropping and fluctuating. I have tried resetting my modem several times to no resolve. I noticed that in the Comcast app it says that my modem is not connected, but it also says that my internet is connected and everything looks good. I wasn’t sure if it was a node in my area or something.
Please help!

I’ve tried this. And it won’t let me log into my modem. When I try to visit the site it just times out

Re: Gigabit internet drops speeds and fluctuates

Some tips then;

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.
