Er, yeah, when you bring Windows into the mix, it’s a lot harder to help. I abandoned Windows; as Horowitz said up there, if you care about security, forget Windows 10. I can’t get too into it, but access denied could be due to something as simple as a new hard drive UID. They tether your wndows key to the ID of your hard drive, which is completely stupid. Also, your wireless downloads of Windows updates are actually on Windows-delegated “hotspots.” Yes, you are sharing bandwidth with total strangers. They assure us everything will be ok.
It goes without saying that you should preferably update via ethernet, not WiFi. Turn off bluetooth. You might want to stay away from cloud backup/restore for a while. There’s a lot going on in your post that I wish I could help with.
I was referring to above configuration. Ignore the comments, when I first got my peplink I created a gallery of noob snaps, questions that were answered and some still loom unanswered---- I took a break. Remember to take a break. I still intend to produce a guide – Problem is, there aren’t a lot of 100% true answers to a lot of basic questions in security, and I am constantly trying to learn things myself. It’s a goal one day to have a document I wish I had starting out. A book like the ComptCIA N+ can serve as a good reference for the basics of how all this stuff actually works. Buy a used copy from 2013.
I honestly have completely abandoned Win for Linux for many reasons. I still use mac from time to time, but not for “serious stuff.” I don’t know anything about Tivo ( I know what it is, but never owned one), but in general start with the most basic possible configuration that gets you online then work up from there.
