Have had a significant amount of buffering on my Smart TV's lately. Discovered a program Advanced IP Scanner in a video while trying to figure out if I have too many devices connected. This program found 12 devices in my house, which I can identify. However, it showed 17,000+ IP's as "unknown" associated with my network. Most of my devices are on LAN, but cell phones are WIFI connected. I have no idea what to do with this problem and/or if it is a cause of the buffering on the TVs..........I have a verified 400 MB download speed with ATT Fiber network. Help would be appreciated very much.
