Ok so we just got a new computer and it was named and setup with out me. Being there. Therefore i thought it named the same thing as a older computer. This resulting in a error on the xp machine (the older one) saying that this machine has the same ip as another device on the network i thought this would be the new computer, It wasn’t.i tried to rename the computer just incase it just freezes, altho i can change the ip and it dont make a diffrence I have cheeded everything on my network nothing is the same. And because of this all 3 of my computers wont work LAN they connect but wont get internet. But the wireless works fine. When i log in to the router it says internet is good when i cheek my internet coming in (fronter router) it is full conection. I cant figure it out. I have a Netgear N900 Wireless Dual Band Gigabit Router (WNDR4500)
