I've looked all over and tried to change my IPaddress with the cmd's /release/renew but it has no effect. My problem is any time I try to open my directory to upload vids or pic's or just open it to look this is what happens. The modem/router shuts down and I get a IP address conflict. It states that another computer is using the same address. This will happen regardless if any other pc or xbox is on or off. I've never had this problem before and it seems no one else has either after searching the internet for answers. I did read something about possibly a codec pac could be causing the problem. I'm using Win 7 and firefox for my browser. Could someone please make some suggestions or help me solve this issue? I'm in my 50's so please be forgive me for my lack of knowledge when it comes to how to do something that comes so easy to some. Thanks for any and all help here. I'm so tired of having to get up and reset both the modem and router each time I want to look in my directory or upload a video which I can not do either at this time. P.S. When I say directory I actually am talking about the windows explorer.
