The laptop sees the wireless router but will not connect or get the IP address. Another computer works fine with the same wireless router.
1. Wireless card driver corrupted.
2. Problems with the operating system.
Possible troubleshooting steps and repair solution:
There could be a problem with the wireless card driver, maybe the driver is corrupted.
Go to the device manager, find the wireless card listed in the network adapter, right-click on the wireless adapter, and uninstall the driver. Now restart the laptop and let it detect the wireless card and reinstall the driver. Test wireless connection.
If it doesn’t help, try downloading the latest wireless driver from the manufacturer’s website and reinstall the driver. Test wireless connection.
If the connection still not working, back up all personal files and reinstall the operating system and device drivers from the recovery disc or installation CD. Test wireless connection.
If the wireless connection still not working, most likely the wireless card has failed. Replace the wireless card.
