I have heard that if you boot Windows and use a VPN, you can open TOR without your ISP being able to see what you are doing (all they can see is that you are connected to a VPN).
What about when I'm using Tails? Does my ISP have any idea what I'm doing? And is it more dangerous to connect to my router with an ethernet cable, instead of just using wi-fi?
Any help would be appreciated. Thanks!
For Tails: By default, your ISP knows you're running Tor. If you select bridge mode, then they probably don't, docs. It probably doesn't matter.
The cable doesn't matter.
