Hello, i just bought a new router and i'm not able to access the internet on one of my laptops even though on the laptop it shows that its connected with full bars, it doesnt have this problem with the other routers i use. Also all my other computers are able to access the internet on this new router. Also if i try to ping yahoo.com or something it says that request is timed out.
Do you see the problem laptop in your router IP address assignment table? Did you enter the correct security type/encryption type/security key in the laptop -- check in the network control panel, manage wireless networks link.
