This procedure addresses some symptoms that you might experience with your PC Card or PCI Adapter, wireless connection, and connection to the Internet:
Verify the physical cable connections between your wireless router or access point, your computer, and your modem.
Ensure that the power outlet to which the router is connected is a live outlet.
Refer to your router's documentation and then check any LEDs or indicators on your router to make sure you are receiving power and that are no errors.
Reboot your router to refresh your Internet connection information.
Some electronic devices, such as 2.4GHz - 5.8 GHz phones and microwave ovens, may interfere with the wireless signal and affect your wireless range and link quality. Try creating a wireless connection on a different channel.
Low link quality or range can be caused by environmental interference, such as lead-based paint and concrete walls. Try to move the antenna of the router or to reposition the wireless clients to improve the link quality. If possible, ensure that there are no obstructions between wireless clients and the router.
Refer to your router's documentation an verify communications between your computer, your router and the Internet.
