The Internet connection is slow or intermittent.

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

. If the ZyXEL Device is sending or receiving a lot of information, 

try closing some programs that use the Internet, especially peer-to-peer 
applications. 

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).

Turn the ZyXEL Device off and on. 

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

• 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. 

The telephone port won’t work or the telephone lacks a dial tone.

Check the telephone connections and telephone wire.

The PHONE light should come on. Make sure that your telephone is connected to 
the PHONE port.

You can also check the VoIP status in the Status screen.
