We have computers hooked up through ethernet and wi-fi. At random times (between 10 seconds and 30 minutes), anyone using the internet connection heavily (like downloading a large file) caused the connection to reset. That is, router uptime goes back to 0, and Windows thinks there is a temporary physical cable disconnection. After fumbling around with every router setting I could imagine that wasn't related to wireless (since I'm having trouble on my computer, which is connected through ethernet), I finally disabled wireless entirely. Problem solved! I'm going to try changing some wireless settings around on the router to try to get it to work. Anyone else had any similar problems, possibly with solutions?
