Re: Daily Loss of Internet Access No file sharing programs. There is a fair amount of auto-syncing going on, especially at night, between my 5 Apple devices and one of my networked PCs via iTunes, and these 5 devices also auto backup to the Cloud every night or so. It is perhaps coincidental that I didn't experience the internet dropouts until after Apple program revisions which enabled wifi syncing and cloud backups?
I do have an Ethernet connected file server but that is just for backing up my PCs. This has been in place for years and is not really active on a daily basis.
Latest proposed troubleshooting step from Verizon is to replace my Optical Network Terminal (ONT). That is scheduled two days from now.
Thanks to all who are aiding my understanding of this issue.
