The Coax cable cord goes directly from the wall to my modem. I also recently had a technician come out to try and fix the issue. The tech was on the phone the entire time with a call center in India trying to resolve the issue. After he was unable to fix it, he kept insisting the issue is with my modem and that I should leasea modem from Cox. Mycurrent modem (compatible with Cox) is brand new and I purchased it because my previous modem had the same issue. Any way to adjust Cable Modem Downstream Power Levels? My internet connection has been terrible for the past two months. I have had a technician come now and nothing has been resolve. After researching around the web, I believe the issue is due to the power level my cable modem is receiving (see attached). Are the power levels normal? If you're unable to see the picture, the power levels are all between -10 to -23. Is there any way to adjust the power level? https://photos.app.goo.gl/6HpaqcmyPwLgoAbp7 Solved
