Arris SB6190 Cable Modem - RCS Partial Service and SYNC Time Sync Failure (100% Packet Loss)
I've gone through 3 cable modems, 3 wireless routers, and a handful of ethernet cables thinking it was a problem with my hardware. I've blocked every other device on the network for troubleshooting this. It's just my PC on it, hardwired in. The internet works without issues for about 90-120seconds at a time, then there's a 30 second period where I get 100% packet loss on everything. I can't get on any websites, I get disconnected from any games I'm running, etc. Then after 30 seconds, everything reconnects okay.
I've rebooted all of my devices three times. I've called Cox and they said everything is testing fine. There's no Cox maintenance in the area and no outages. No construction in the vicinity. Is there anything I could do to diagnose this? Can I buy anything to test the coax drop in the wall or something?
