Wireless Client Connections

The following are common issues observed with wireless client connections:

n

Wireless Client Unable to Connect to AP

n

Wireless Client Unable to Get an IP Address

n

Wireless Client Unable to Pass Traffic

n

Wireless Client Fails 802.1X Authentication

n

Wireless Client Fails MAC Authentication

n

Wireless Client Fails to Reach Captive Portal Authentication Page

n

Wireless Client Fails Captive Portal Authentication

Wireless Client Unable to Connect to AP

The following procedure describes how to troubleshoot issues, if the wireless client fails to connect to the
AP:

1.

Check the SSID Configuration of the Wireless Network

2.

Verify if the SSID is Broadcasted by the AP

3.

Check the Quality of RF Environment

4.

Check the Channel Change Behavior of the Broadcasting Radio

5.

Check the Authentication Message Exchange Between the AP and Client

Check the SSID Configuration of the Wireless Network

The SSID settings must be defined to support the desired clients. The following are SSID configurations that
impact a client's ability to discover and connect to the network:

n

SSID settings

— The SSID must be enabled and visible for clients to join the network. Ensure that

Hide

and

Disable

options are disabled in the SSID settings.

n

Operating radio bands

— The SSID must be broadcasted on the RF bands supported by the client.

Ensure that the SSID is operating on the RF band supported by the client.

n

Minimum and maximum transmit rates of the radios

— The minimum and maximum transmit

rates of the radio must include the transmit rates supported by the client. Use the following table as
reference when configuring transmission rates for the network: 

IEEE Standard of the
Client

Supported Bands

Supported Transmit Rates

Legacy 802.11

2.4 GHz

1 to 2 Mbps

802.11a

5 GHz

Up to 54 Mbps
