So here is the problem, my computer (specs below) won't stay connected to my network for more then 30 minutes at a time. It losses connection to my router then randomly reconnects, and runs very slow. It's not Comcast, since all over computers and devices connect and run at normal speeds. The tray has 2 connection programs, the one built in to windows and Realtek which came with the wireless card. My setup is, the computer connects to the router ether through wireless card or through an Ethernet cable running through an Action Tech power line Ethernet adapter(its currently hooked up to a different computer and works great). The router connects to our 'Comcast box' and from there to the outside. When I check the network setting during the down time there is a red X between 'This computer' and 'Network'. Any advice on how to fix this would be greatly appreciated since I need that computer online for college.
One thing iv been recommended to to was changing the speed/duplex settings and discharging the mobo, both did nothing.
