I got weird issue going on. At random times during the day i get really bad lag on anything i do online and the house phone has static on it. I run ping test though cmd prompt and i get server timeouts but when i run a ping test on pingtest.net and i call the cable company they say nothings wrong. Even the modem says nothings wrong. This been happening since December and my cable company cant seem to find out whats wrong. Well there was a few things wrong the amp on the line needed to be replaced and the transmission lvls kept spiking but they fixed that. All equipment in the house has been replaced. Basically all diagnostics equipment expect for cmd prompt says everything ok. Any help would be appreciated.
