Some Common Cisco Aironet Access Point FAQ


Q. What is the default user name and password for Cisco IOS® Software-based APs?

A. Cisco IOS Software-based APs have a default configuration that includes a user name and password combination, both of which are Cisco (case sensitive). After you reset to factory defaults, be ready to give Cisco as both the username and password when either the GUI or the command-line interface (CLI) prompts you.


Q. What cable should I use for a console connection?

A. Use a straight-through cable with nine-pin male to nine-pin female connectors in order to connect the COM1 or COM2 port on your computer to the RS-232 port on the AP. Use a terminal emulation program on your computer, such as:


Microsoft Windows HyperTerminal

Symantec ProComm



Use these port settings:


Speed:           9600 bits per second (bps)

Data bits:           8

Stop bits:           1

Parity:           None

Flow Control:           Xon/Xoff

Note: If the flow control Xon/Xoff does not work, try using the flow control None.


Q. How do you check the radio type on autonomous AP?

A. You can use the show controllers command from the privileged EXEC mode on the AP to get information on the radio type.


Q. How do you set up an IP address on the AP?

A. By default, the AP requests an IP address through DHCP.


Cisco IOS Releases 12.3(2)JA and later change the default behavior of APs requesting an IP address from a DHCP server:


When you connect a 1200 or 1230 series AP with a default configuration to your LAN, the AP requests an IP address from your DHCP server. If it does not receive an address, it continues to send requests indefinitely.


When you connect an 1100 series AP with a default configuration to your LAN, the 1100 series AP makes several attempts to get an IP address from the DHCP server. If it does not receive an address, it assigns itself the IP address for five minutes. During this five minute window, you can browse to the default IP address and configure a static address. If after five minutes the AP is not reconfigured, it discards the address and reverts to requesting an address from the DHCP server. If it does not receive an address, it sends requests indefinitely. If you miss the five minute window for browsing to the AP at, you can power-cycle the AP to repeat the process.


You can also manually set the IP address of the AP. On a Microsoft Windows PC that is connected to the Ethernet segment, from the DOS prompt, issue this command:


arp -s a.b.c.d 00-12-34-56-78-90


Note: The term a.b.c.d represents the IP address that is to be set on the AP, and 00-12-34-56-78-90 is the MAC address. This address appears on the panel on the bottom of the AP.


Issue this command in order to verify the address:


ping a.b.c.d


Note: This procedure does not work if the AP has already been assigned an IP address by another method.


Q. How do you enable HTTPS access on the AP?

A. In order to enable HTTPS, you must add this command to your AP:


AP(config)#ip http secure-server

When you add the ip http secure-server command, you see the RSA keys required for secure communication regenerated on the APs.


Q. How do you extend the coverage of the AP?

A. There are several ways to extend the coverage area for an AP. These are the most important methods:


Use APs in repeater mode.

Use a secondary AP in AP mode with nonoverlapping channels.

Change the transmitter power level parameter of the existent AP in order to extend the coverage.

Position the APs optimally.
