hi like the title says. im figuring out this for a week now , i have 4 computer connected to linksys e1200 router. everytime im playing lol and dota 2 my ping jumps from 50 to 200 and getting a packet loss of 15% then back to normal then gets high again. this is what i already tried. 1. check the quality of my internet which has no probem. 2 check if there is downloading in the background. 3.format my pc 4. check the cabling 5. connecting solo to router. 6.configure qos. and last time i tried playing without any open apps and still getting lag spikes. i want to detect the cause of it so ill find the solution. so just a simple advice would be appreciated.
