I cannot access the Internet.

1 Check the hardware connections, and make sure the LEDs are behaving as expected. See 

the Quick Start Guide and 

Section 1.5 on page 27

.

2 If you are trying to access the Internet wirelessly, make sure the wireless settings in the 

wireless client are the same as the settings in the AP.

3 Disconnect all the cables from your device, and follow the directions in the Quick Start 

Guide again. 

4 If the problem continues, contact your ISP. 

V

I cannot access the Internet anymore. I had access to the Internet (with the 
ZyXEL Device), 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 1.5 on page 27

.

2 Disconnect and re-connect the power adaptor to the ZyXEL Device. 
3 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 1.5 

on page 27

. 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. 

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).

3 Disconnect and re-connect the power adaptor to the ZyXEL Device. 
4 If the problem continues, contact the network administrator or vendor.
