A broken wireless connection can be annoyng at least and crippling at worst. If your laptop's wireless network adapter is still on the fritz after rebooting your computer and disabling then re-enabling the adapter interface didn't fix the problem, you don't have to run out and buy a new adapter just yet. You can still update the device's driver to its latest version, and launch Windows' internal repair wizard to fix the adapter and get back to work.
Step 1
Plug one end of the Ethernet cable into the LAN port on the laptop and the other end into a numbered port on your router or Ethernet port on your modem.
Step 2
Click on the Windows orb in the bottom left corner of the screen. Click "Control Panel" then "System Maintenance."
Step 3
Click on "Device Manager," and then enter an administrative password if Windows prompts you to do so.
Step 4
Expand the "Network Adapters" list entry. Right-click on the network adapter you are trying to repair, and then select "Properties."
Step 5
Click the "Driver" tab in the window that posp up, and then select "Update Driver."
Step 6
Close the Control Panel windows and try connecting to the Internet again. If the adapter is still not successfully connecting, right-click on the adapter's icon in the taskbar in the lower right hand portion of the screen. Select "Diagnose and repair," and then proceed to follow the instructions in the window that comes up.
