If you are using external headphones or speakers, check that they

are securely connected to your computer.

This is feedback between the microphone and the speakers. It

occurs in any sound system when input from a microphone is fed to

the speakers and the speaker volume is too loud. Adjust the volume

Wireless networking problems

This section provides general troubleshooting tips for networking

problems, specifically wireless (Wi-Fi

The terms and concepts used assume a basic understanding of

networks, and may be for more advanced users. If you need

assistance or if you are not familiar with the terminology, please see

If your computer is equipped with an internal Wi-Fi

adapter,

verify that the Wireless antenna is ON (the wireless indicator

will be lit).

❖

Verify that your computer can detect access points or routers. If

it can detect a Wi-Fi

access point or router then it may be a

configuration issue.

❖

Verify that signal strength is good using the utility provided

with the Wi-Fi
