Does your wireless router seem to work great for a time on all your devices but then it periodically disconnects for no reason? Even when an ethernet cord is in use rather than a wireless connection? More than likely the problem lies in your Dynamic DHCP Clients, aka the various devices connected to your router, simply expiring. For reasons unknown this seems to be a huge state secret, and not something the router just automatically does. To solve this annoyance log in to your routers control panel that is usually accessable from a web browser at http://192.168.0.1/. Then look for Add A DHCP Reservation under Network Settings which is usually under the Setup option. Choose your device from the list or copy the information from the device listed on the page. Once you add a reservation the device should never expire which means it will never disconnect on you ever again!
