This is 90% of my job every day. Something in your house is acting like an antenna and interfering with the return path. Most of the time it’s a loose connector behind the modem but any bad connection can cause it. I usually track the noise to a house and use a filter at the tap that blocks the noise and leaves the sub online, then create a job to get an tech in the house
Can confirm this, former signal engineer for the first cable internet provider and a ham. Bad connections, unmatched RG-8, and trashed filters were the bane of my existence. That and crappy installers. Thank the deities for QoS.
