First of all, I'm sorry for my freaking bad english, as its not my native language. Please, I REALLY need help with this. Pretty important things to say: Im connected with ethernet cable. If I connect with wifi it works (but the adapter I used wasn't mine, a friend gave it to me so I could try out) The cable is working fine, I tried that out with another pc. I didn't really touch any Hardware, neither drivers. That's why its in Software (It might be wrong) If I connect to my Phone internet, with the sharing internet option, IT WORKS I HAVE 360 SECURITY ANTIVIRUS I already runned malware antibytes I already runned CCleaner Here's the problem: One day, I turned on my PC. Everything was normal, connection was working. Well, thats what I thought, until I opened Skype. Instead of the green connected logo, I had the reconnecting one, like I was having a connection problem. The really weired thing was that I could recieve and send messages, but I couldn't call anyone as skype was thinking I was not connected. I didn't think it was a problem, maybe it was bugged or something. Then, I opened League of Legends like every friday, logged in and everything fine, well, I couldn't connect to the game chat but I thought it was not a problem as sometimes the server get bugged. I started a normal game and BUM, I had 30 ms (nice ping) but the "Attempting to recconect" window was there. I had to play with it, still thinking it was a server problem. But, then I opened google chrome, some pages were loading fine, like Google, Facebook, Youtube. But others didn't even load (sometimes it did, sometimes not). One thing I noticed is that I can't get into websites with a "ddos protection", like Nulled.io or other forums. Thank Guys.
