Hello everyone. I often host LAN party with friends in weekend. We usually play Warcraft 3, Red Alert2: Yuri's Revenge or CSS. There wasn't any problem before. Our gameplay was smooth and okay. Until recently we experience random freeze for like ~5sec and get back normal for 1 or 2 mins and then it happens again and the gameplay getting slower and slower as time passes by. When we play CSS, sometimes I see my friends' ping hike up from 10 to over 800 or 900 randomly. It happens to anyone except for the game hoster. I use this program called "mHotspot" to create connection so my friend can join my network and we can play over LAN (We're on laptops).



Any suggestion and solution is gratefully appreciated
Thanks.
