Chapter 13 Troubleshooting

4Check your WiMAX settings. The WiMAX Device may have been set to search the wrong frequencies for a wireless connection. See Chapter 6 on page 72. If you are unsure of the correct values, contact your service provider.

5Disconnect all the cables from your WiMAX Device, and follow the directions in the Quick Start Guide again.

6If the problem continues, contact your ISP.

I cannot access the Internet any more. I had access to the Internet (with the WiMAX Device), but my Internet connection is not available any more.

1Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide and Chapter 14 on page 203.

2Disconnect and re-connect the power adapter to the WiMAX Device.

3If the problem continues, contact your ISP.

The Internet connection is slow or intermittent.

1The quality of the WiMAX Device’s wireless connection to the base station may be poor. Poor signal reception may be improved by moving the WiMAX Device away from thick walls and other obstructions, or to a higher floor in your building.

2There may be radio interference caused by nearby electrical devices such as microwave ovens and radio transmitters. Move the WiMAX Device away or switch the other devices off. Weather conditions may also affect signal quality.

3There might be a lot of traffic on the network. Look at the LEDs, and check Chapter 14 on page 203. If the WiMAX Device is sending or receiving a lot of information, try closing some programs that use the Internet, especially peer-to-peer applications.

4Disconnect and re-connect the power adapter to the WiMAX Device.

5If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions.

The Internet connection disconnects.

1Check your WiMAX link and signal strength using the Strength Indicator LEDs on the device.

2Contact your ISP if the problem persists.
