•
Make sure that the “Signal Strength” indicator on the “Link Info” tab is not
zero. A minimum of 20% is recommended. If the “Signal Strength” is less
than 20%, the distance between the ACR-201-G and the targeted radio
(an AP or another Station) may be too far. Decrease the distance to see if
the radio link can be established.
•
Make sure that the SSID is “ any ” or “ ANY ” or the same as that for the
Access Point if operating in the infrastructure mode, or the same as that of
the other Stations if operating in the Ad Hoc mode.
•
Make sure that the encryption keys are entered correctly if WEP is
enabled.
•
Make sure that there is no RF interference present in the radio network.
No Network Connection While the Radio Link is Good
If the “Communication Strength” indicator shows good link quality on the “Link
Info” tab but the host computer/device cannot be connected to the network, the
cause might be one of the followings:
•
Make sure that the Yellow LED on the radio is NOT constantly ON. If it is,
Ethernet connection is questionable.
•
Make sure the Ethernet Bridge Station of the host computer/device is
properly installed.
•
Make sure that the UTP cable connecting the radio and the host device
meets at least the CAT-3 standard and has a straight-through connection
if the host device is a PC, or a crossover if the host device is a hub or
switch.
•
Make sure that the IP address of the host computer/device is properly set
up for the network.
•
Make sure that the host computer/device has initiated some packet traffic
since the radio was turned on. (That is the failure of the network
connection is not just determined by trying to access the host from a
remote point in the network.) Reset or re-power the host with the ACR-
201-G turned on may be necessary in order for the ACR-201-G to “learn”
the MAC address of the host computer.
Poor Link Quality
If the “Communication Strength” stays in the Poor range, check for the following
conditions:
•
Make sure that radio interference is not present in the radio network.
