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 1.4.4 on page 56.
2 Check the schedule rules. Refer to Chapter 47 on page 681 (SMT).
3 If 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).
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 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.
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

activating it. If it is enabled, you might consider changing the allocations.
