Chapter 48 Troubleshooting

I cannot access the Internet anymore. I had access to the Internet (with the ZyWALL), but my Internet connection is not available anymore.

1Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide and Section 1.4.4 on page 56.

2Check the schedule rules. Refer to Chapter 47 on page 681 (SMT).

3If you use PPPoA or PPPoE encapsulation, check the idle time-out setting. Refer to the Chapter 8 on page 165 (web configurator) or Chapter 32 on page 565 (SMT).

4Reboot the ZyWALL.

5If the problem continues, contact your ISP.

The Internet connection is slow or intermittent.

1There might be a lot of traffic on the network. Look at the LEDs, and check Section 1.4.4 on page 56. If the ZyWALL is sending or receiving a lot of information, try closing some programs that use the Internet, especially peer-to-peer applications.

2Check the signal strength. If the signal strength is low, try moving the ZyWALL closer to the AP if possible, and look around to see if there are any devices that might be interfering with the wireless network (for example, microwaves, other wireless networks, and so on).

3Reboot the ZyWALL.

4If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions.

Advanced Suggestions

•Check the settings for bandwidth management. If it is disabled, you might consider activating it. If it is enabled, you might consider changing the allocations.
