Troubleshooting

Networking

What should I do if my computer cannot connect to a wireless LAN access point?

❑ Connection availability is affected by distance and obstructions. You may need to move your computer away from

obstructions or closer to any access point you may be using.

❑ Make sure the WIRELESS switch is on and the WIRELESS indicator is lit on your computer.

❑ Make sure power to the access point is on.

❑ Follow these steps to check the settings:

1 Click Start and Control Panel.

2 Click View network status and tasks under Network and Internet.

3 Click Connect to a network to confirm that your access point is selected.

❑ Make sure the encryption key is correct.

❑ Make sure Maximum Performance is selected for Wireless Adapter Settings in the Power Options window. Selecting

any other option may result in a communication failure. To change the settings, follow these steps:

1 Right-click the power status icon on the taskbar and select Power Options.

2 Click Change plan settings under the current power plan.

3 Click Change advanced power settings.

4 Select the Advanced settings tab.
