Chapter 54 Troubleshooting V I cannot access the Internet anymore. I had access to the Internet (with the ZyWALL), but my Internet connection is not available anymore. 1 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide and Section 2.6 on page 59. 2 Check the schedule rules. Refer to Chapter 53 on page 757 (SMT). 3 If you use PPPoA or PPPoE encapsulation, check the idle time-out setting. Refer to the Chapter 9 on page 169 (web configurator) or Chapter 38 on page 639 (SMT). 4 Reboot the ZyWALL. 5 If the problem continues, contact your ISP. V The Internet connection is slow or intermittent. 1 There might be a lot of traffic on the network. Look at the LEDs, and check Section 2.6 on page 59. If the ZyWALL is sending or receiving a lot of information, try closing some programs that use the Internet, especially peer-to-peer applications. 2 Check 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). 3 Reboot the ZyWALL. 4 If 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. 54.4 Wireless Router/AP Troubleshooting V I cannot access the ZyWALL or ping any computer from the WLAN. 1 Make sure the wireless LAN is enabled on the ZyWALL 2 Make sure the wireless adapter on the wireless station is working properly. 3 Make sure the wireless adapter (installed on your computer) is IEEE 802.11 compatible and supports the same wireless standard as the ZyWALL. 4 Make sure your computer (with a wireless adapter installed) is within the transmission range of the ZyWALL.
