So, twice in the last few weeks, I've gotten a random windows error that's popped up. It says(and this is a paraphrase) that "Another computer on this network has the same IP as this computer, please contact windows, blah blah blah". It doesn't seem to affect anything, nothing shuts down or anything. Thing is, I don't have another computer, there is no "network", and as far as my internet goes, it's password protected(and it's not password either. LOL). So....what's going on, and why?

Sounds like the router has assigned the ip your computer uses to another device

Oh, like my wifes tablet? She does use it on there.

Yup

Well, that solves that mystery then. Thanks for the info!
