In my house I have the wireless router sitting on the first floor and my computer sit in my room on the third floor. The router signal is encrypted and I modified the router so that on certain mac address are able to use the network so that if some one is able to hack into our network they will not be given an ip address. My problem s that the wireless keeps dropping out on my windows XP laptop. It some times takes a long time to reconnect. when I search for the network it some times doesn't so up and when it does I click connect my computer won't connect to it. Does anyone know what I could do so that the signal stops dropping out on me.
