Reboot the Computer
It seems trivial, but you should always begin troubleshooting computer problems by rebooting your computer! This is particularly important if your computer has worked fine in the past and only just began to exhibit problems.
Power-Cycle the Wireless Unit
Power-cycling the wireless unit causes it to re-synchronize with the tower.
- Unplug then wait 30 seconds.
- Plug the wireless unit back in. Wait another 60 - 120 seconds.
- Restart your computer.
Remove Network Devices
Remove any network devices (such as hubs, wireless routers, or network switches) that sit between your computer and the DSL router. By running your computer directly into the DSL router, you can eliminate the possibility that another device on your network is causing the problem.
Firewall
If you are running a third-party firewall program on your computer, these may be interfering with your computer?s ability to access the Internet. Try disabling any firewall program that you have running.
