box and ensure that the values are correct. If the values are incorrect, enter the correct
frequency settings in the Network > WAN > WiMAX Frequency screen. If you are

5 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.
6 Disconnect all the cables from your ZyXEL Device, and follow the directions in the
Quick Start Guide again.

1 Check the hardware connections, and make sure the LEDs are behaving as expected. See
the Quick Start Guide and Section 1.2.1 on page 35.

The Internet connection is slow or intermittent.
1 The quality of the ZyXEL Device!s wireless connection to the base station may be poor.
Poor signal reception may be improved by moving the ZyXEL Device away from thick
walls and other obstructions, or to a higher floor in your building.
2 There may be radio interference caused by nearby electrical devices such as microwave
ovens and radio transmitters. Move the ZyXEL Device away or switch the other devices
off. Weather conditions may also affect signal quality.
3 As well as having an external antenna connector, the MAX-210HW2 is equipped with an
internal directional antenna. If you know the location of the base station, orient the front
of the ZyXEL Device (the side with the LEDs) towards the base station. If you do not
know the location of the base station, experiment by moving the ZyXEL Device while
observing the SIGNAL LEDs for an increase in received signal strength. The MAX-
200HW2 and MAX-230HW2 do not have internal antennas.
4 There might be a lot of traffic on the network. Look at the LEDs, and check Section 1.2.1
on page 35. 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.
