Streaming video has a problem when using My Files in aTV Flash v1.3

Hello everyone…


I have an ATV2 runs aTV Flash Black for a while. Everything’s been working fine until recently I’d upgraded aTV Flash Black to 1.3 and changed my router to Linksys E4200v2. Since there every time I use My Files in aTV Flash to stream video from my PC (Windows 7 Pro 64bit), the screen of PC turns white out and WiFi connection was disconnected . But I can stream video through XBMC without any hitccup. Can anyone help me figure out is that the aTV Flash v1.3 or my router causes the problem. Thanks
