Mobile Unit Issues
This section describes various issues that may occur when working with the mobile units associated
with the wireless controller or associated Access Points. Possible issues include:
● Access Point Adopted, but MU is Not Being Associated
● MUs Cannot Associate and/or Authenticate with Access Points
● Poor Voice Quality Issues
Access Point Adopted, but MU is Not Being Associated
Access Point associated with an MU is not yet being adopted. The table below provides suggestions to
troubleshoot this issue.
MUs Cannot Associate and/or Authenticate with Access Points
MUs cannot associate and/or authenticate with Access Points. The table below provides suggestions to
troubleshoot this issue.
Possible Problem Suggestions to Correct
Sensor Port flapping
(going up and down)
This may be caused by the sensor being unable to find its server. Ensure
that the detection configuration is correct and that all cables are secure.
All else... Contact Extreme Networks Support
Possible Problem Suggestions to Correct
Unadopted Access Point Verify that the controller has adopted the Access Point with which the
MU is trying to associate
Incorrect ESSID applied
to the MU
Verify on the MU the correct ESSID has been applied to the MU
Ethernet port
configuration issues
• Verify that the Ethernet port connected to thenetwork and has a valid
configuration.
• If DHCP is used, verify that the Ethernet cable is connected to the
same NIC upon which DHCP services are enabled
Incorrect security settings Verify the correct security settings are applied to a WLAN in which the
MU is tryng to associate
All else... Contact Extreme Networks Support
Possible Problem Suggestions to Correct
Preamble differences Verify the preamble type matches between controller and MUs. Try a
different setting.
Device key issues Verify in Syslog there is not a high rate of decryption error messages.
This could indicate a device key is incorrect.
MU is not in Adopt List Verify the device is not in the “do not adopt ACL”.
Encryption Problems If Encryption is being used, verify the encryption settings on the MU and
the controller match.
If WEP encryption is used on the WLAN, ensure proper encryption key in
either HEX format or Passphrase is used on the MU.
