The Internet connection is slow or intermittent.
1 There might be a lot of traffic on the network. 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 Make sure the ZyXEL Device is installed in a position free of obstructions.
3 Check the signal strength. If the signal is weak, try moving your computer closer to the
ZyXEL Device (if possible), and look around to see if there are any devices that might
be interfering with the wireless network (microwaves, other wireless networks, and so
on).
4 Reboot the ZyXEL Device.
5 If the problem continues, contact the network administrator or vendor, or try the
advanced suggestions.
