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 34 .
2
Disconnect and re-connect the power adapter to the WiMAX Device.
3
If the problem continues, contact your ISP.
The Internet connection is slow or intermittent.
1
The quality of the WiMAX Device’s wireless connection to the base station may be
poor. Poor signal reception may be improved by moving the WiMAX 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 WiMAX 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 WiMAX 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 WiMAX Device while observing the Strength Indicator 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 34 . If the WiMAX Device is sending or receiving a lot of information,
try closing some programs that use the Internet, especially peer-to-peer
applications.
5
Disconnect and re-connect the power adapter to the WiMAX Device.
6
If the problem continues, contact the network administrator or vendor, or try one
of the advanced suggestions.
The Internet connection disconnects.
1
Check your WiMAX link and signal strength using the WiMAX Link and Strength
Indicator LEDs on the device.
2
Contact your ISP if the problem persists.
