On Friday the Internet suddenly went out. Turned out our modem (a TC8305C) was restarting itself. I looked at the log and saw TLV-11 - unrecognized TLV. I also see some T3 Timeouts in our log as well. Usually our log is very clean. We were also having some problems with Netflix last night. I restarted the Gateway/Chromecast and the problems seemed to go away for the most part. Could this be the cause of some bad signal outside? Inside wiring is still very new. Any suggestions would be greatly appreciated.
