Hello everyone.
My internet connection really makes me go mad. Disconnecting from any game after 3-6 or in lucky times, 10 minutes. Really bad download speed(not what i should be getting) and other latency issues. So, i called my ISP and told them all that "good stuff". They came to my house did some stuff and i'm still getting this issue, when i did show them these system logs they didn't know what the hell that was, neither do i. So please, anyone, if you know what these logs mean and how to fix them, tell me.
Router model : LB-Link BL-WA310AP 300Mbps. My connection is wired.
