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 

2 Check the schedule rules. Refer to

4 Reboot the ZyWALL. 
5 If the problem continues, contact your ISP.

The Internet connection is slow or intermittent.

1 There might be a lot of traffic on the network. Look at the LEDs, and check 

. 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.

• 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.

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.
