This problem started about a month ago. For some reason if I plug the ethernet cable directly into the computer it just says unidentified network but if I plug the same ethernet cable into a wifi router if works (not all the time tho, sometimes it says unidentified network even if I do it this way). Nothing has changed since then with the internet nor with my computer, this problem just randomly started. I'm using windows 10 and I have an Acer Aspire V3-572g laptop. I tried reinstalling the OS, the drivers, pretty much tried everything I could find via google but nothing helped. Any suggestions?
