V The Internet connection is slow or intermittent.

1 There might be a lot of traffic on the network. 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 ZyXEL Device

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).

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.

• Check the settings for QoS. If it is disabled, you might consider activating it. If it is

enabled, you might consider raising or lowering the priority for some applications.
