How do i fix my internet issue with Toshiba laptop

You may have virus. Try system restore to earlier date and perform a virus scan.

Have you performed a virus scan yet?

above the start icon which is the window icon on the bottom left is a menu and on that menu is device manager, click device manager and it shows list of devices, on the list is network adapters. Open that branch by clicking on the > You should see the network adapter. If there are any ! or X or it is marked as unknown then you have driver issue. You can use another computer to download the driver and install it.

sounds like a virus either way a reinstall will sort it back up any documents and pics first

I would download the updated drivers and firmware from www.toshiba.com It sounds like you have driver issues.
Hope that helps.

Using device manager uninstall, reboot and reinstall the wi fi chip. If this does not work you are in deep doo doo because the chip is fubar. I had the same issue with a Toshiba laptop but I returned it since it was a few days old. The chip is soldered to mo bo and unless you have real special tools and skills it cannot be removed.

The Touchpad is the cause. Although some work fine for years others jump the the pointer every time you type (or sneeze). You can turn the touchpad off if you have a mouse for the laptop. Otherwise, you might need to exchange/purchase another model laptop.

Try the properties of your Network controller. And go to your Internet Protocol Version 4 and 6 properties. Sometimes you have to change from Auto Obtain to manual and back again to get the IP addresses to correct themselves. Hope this helps.

install a new operating system using dark edition win xp profetional and install the given board drivers and then try. if not you try to check where the pin is to be inserted and see if it is loose then try the person who nows electronics to fix it back for you

I think your fan might be broken....if the fan doesn't cool the pc,the processor or the chipset will automatically shut down the pc to prevent burning hardware.Or your hard drive might keep crashing.Oh yeah and abstract from this i don't recommend ever using mcaffe
