Solve : Computer can't connect to the internet?

1.	Solve : Computer can't connect to the internet?
Answer» I have a wireless router that I want to use to connect my laptop to the internet. When I bought the router, my computer connected perfectly WELL to the internet. However, I took the laptop to college and used it on the internet there for a few months. Now that I am back at home trying to connect to the internet using the wireless router again, my computer can't connect. My computer won't even connect to the internet when it is plugged directly into the modem. It says that I am connected to the wireless network, but when I open a browser, the internet doesn't work. Signal strength is excellent. I know the wireless router is okay since my home desktop computer connects to the internet just fine when plugged into it. I think some settings may have been changed on my laptop when I took it with me to college. How can I get my laptop to connect to the internet through the wireless router again? I run Windows Vista on my Toshiba Satellite laptop. My router is made by DynexUnplug the router for 30 seconds. Plug it back in, and wait another minute, and try to reconnect to it. Also try directly plugging your computer back in at this time. I'm guessing its your parents internet as well? Make sure they paid their bill, if they dont have a computer or use the internet, they may have canceled. Second, on the computer having the problems, press the Start menu button, and type in: cmd right click "CMD" and click "Run as Administrator" In command prompt (CMD), type: ipconfig /release ipconfig /renew ipconfig /flushdns Some of these steps may take longer than others. Still not working? On the wireless icon NEXT to the system clock in the system tray/taskbar, right click the wireless, and go to "Repair" (It may also be called Troubleshooting) it should automatically try to detect the problem. Be sure to tell us what it says.

My computer won't even connect to the internet when it is plugged directly into the modem.

It says that I am connected to the wireless network, but when I open a browser, the internet doesn't work. Signal strength is excellent.

I know the wireless router is okay since my home desktop computer connects to the internet just fine when plugged into it. I think some settings may have been changed on my laptop when I took it with me to college. How can I get my laptop to connect to the internet through the wireless router again?

I run Windows Vista on my Toshiba Satellite laptop. My router is made by DynexUnplug the router for 30 seconds.
Plug it back in, and wait another minute, and try to reconnect to it. Also try directly plugging your computer back in at this time.

I'm guessing its your parents internet as well? Make sure they paid their bill, if they dont have a computer or use the internet, they may have canceled.

Second, on the computer having the problems, press the Start menu button, and type in:
cmd
right click "CMD" and click "Run as Administrator"
In command prompt (CMD), type:

ipconfig /release
ipconfig /renew
ipconfig /flushdns

Some of these steps may take longer than others.

Still not working?
