I did a full modem clear reset, which helped, but noticed it started again last night around midnight. Looking at the cable modem log files, it looks like a time sync error where the modem is getting a 1/1/1970 date from the cable service, which then won't connect properly with the Internet service, (access denied error) This is common with computers when connecting to a network. I'm not sure where that date is coming from, but it seemed to resolve again early this morning. Cox, what could be causing this, and what is the solution?
