What are the issues that cause a router to hang? I have a router that has 15 machines of which 3 are on WiFi. Also there are 2 ip cameras. The network is entirely dedicated for a project relating to the camera, so the camera is accessed and video is streamed through that continuously. So my router doesn't respond once in a while. but a restart solves the issue. My router is a Cisco linksys E1200. Any help or suggestions on this ?
