This procedure addresses some symptoms that you might experience with wireless network:
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, access point and modem to make sure you are receiving power and that are no errors.
For connectivity issues, reboot your DSL or cable modem and wait for the LEDs to stabilize, then reboot your router and wait for the LEDs to stabilize, then reboot your access point (if present) and wait for the LEDs to stabilize. Finally, reboot your computer.
Other devices connected to the router may need to re-establish their network connections.
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 access point 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 or access point's documentation and verify communications between your computer, your router and/or access point, and the Internet.
