Blank Pages Appear When Open the Utility Program

This is either because the radio is extremely busy on the RF side or because the Ethernet connection is problematic. Try to hit the Refresh button a few times. If the blank-page condition persists, it is unlikely that the problem is caused by a busy radio. Check your Ethernet connection. Make sure you use at least a legitimate CAT-3 cable, but preferably a CAT-5. Make sure that it is a straight- through cable between the radio and the computer, or a crossover cable between the radio and the hub, if a hub is involved. Check to make sure that the Ethernet card of the computer running the Utility program is functional.

No Radio Link When Set Up As a Station (ACR-201)

If the AirEZY-2411-BT is intended to function as a Station but the “Link Quality” indicator on the “Link Info” tab shows 0%, check the following possible causes:

•Make sure that a target radio, an AP or another Station, is turned on and operating properly.

•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 AirEZY-2411-BT 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 AirEZY-2411-BT is set up as a Station, not an AP.

•Make sure that the SSID is “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 all the access controls are satisfied if operating in an infrastructure mode (i.e., connecting to an AP). For example, is the MAC address of the host computer/device of the AirEZY-2411-BT Station entered in the AP?

•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 Radio Link When Set Up As an AP (ASR-102)

If the AirEZY-2411-BT is set up as an AP, but one or more target Station radios cannot link with it, check the following:
