Acer Aspire One 722 Troubleshooting

Audio Problems

You have trouble listening to sounds on your computer.

Volume Controls

It’s a common mistake that is made. Check your sound icon and raise the volume bar to a higher level if it’s very low. Also, when watching videos and listening to music check that the volume bar in the application is heightened too.

Laptop Has Been on Too Long

Laptops develop strange issues when they’re on for too long. Restarting your laptop will refresh your device and clear up most issues like audio problems.

Faulty Driver

If you have a hard time listening to any sounds through your laptop speaker, or if your audio is distorted, this might be a result of having a faulty driver. You can check this by going to the Device Manager and then click on the Sound, video and game controllers. The Device Manager will tell you the manufacturer and model. If there is a yellow or red exclamation point next to the sound device this probably means you’re missing a driver and will have to find and download the latest drivers for your version of Windows. To install the driver, you can go to: http://www.acer.com/.

Microphone Not Working

No voice recording or output.

External Cable Connections

If you can’t record your voice into your laptop you should check which cable port you’re plugged into. Make sure external cable connections for recording is plugged into the microphone port.

Internal microphone

If it is an internal problem with your built-in microphone, updating your driver for your microphone will solve this problem.

Loose Headphone Jack

If your audio cuts in and out or is distorted in any way, this is usually a sign of having a loose headphone jack. Inserting the jack fully into the computer can solve this issue. If the jack is fully inserted and problems are still occurring, then your microphone itself may be faulty.

Problems with Wireless Connection

The netbook will not detect or connect to wireless connections.

Wireless Button

Check if the wireless button is actually on. Users inadvertently turn this button off and don’t realize it. This button is usually above the keyboard.

Wireless Connection

If you think there is an issue with the connection you're using, try to connect to that same connection with a different device. If the other device works well on that connection, then the wireless connection is not the problem.

Router Settings

Check the router setting of the Acer Aspire One 722. Make sure that you have the DHCP (Dynamic Host Configuration Protocol) turned on and don’t have the mac filtering on. This can mess up the connection between your wireless connection and this device.

Router Type

The router type factors when it comes to the Acer Aspire One 722 wireless connection. A D-Link router doesn’t blend well with this device. This router tends to think that this device is still broadcasting and that kills wireless connection.

Acer Wireless Drivers

If the wireless connection is fine, and there is nothing wrong with the router type or settings, than the problem is most likely your Acer Wireless Drivers. Drivers need to be kept up- to-date and if they’re not then they become damaged. To manually install your updated Driver you can go to http://www.acer.com/ and find and download the missing Drivers that your laptop needs. The website may give you instructions to help guide you with your installation.
