I've been trying to pinpoint exactly what is causing our internet or our wireless network to get super slow after a few hours of any restarting of the router. I noticed that when I kick my roommates off the network it goes super fast, but once I let them on it gets extra slow after awhile. What might be causing this? What should I be looking for on their systems that might be the cluprit? Or my own? It's a Netgear WGR614 v6 Router.
