HI , I just changed my OS from Windows to Elementary, my wifi is not working since, I have an access to internet via USB tethering to my phone (don't worry about my data). My Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller is not working on my Acer V3-112P Series I spend more than 20 hours trying to fix this problem by myself on different forums, following different protocol writing codes I founded online in my terminal but all of it was a fail, I just made it worst, so I installed Elementary a 2nd time , now virgin of any mistake, and I'm now humbly asking you to help me with that, please.
