Cisco Access Point (AIR-LAP1142N-S-K9)

Power on the Cisco Access Point and press the mode button to reset the previous setting then connect the console cable rj-45 end to the AP and usb end to the laptop. For its configuration we need two things.
- Putty Download link https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
- Driver of COM port

Run the putty setup and select Serial from the connection type

You have to check whether your COM port driver is installed properly and its name would be like COM5(it differ with everyone). you can check under the device manager and select the Ports tab. If the driver doesn't installed properly then the yellow triangle would appear.

After the COM driver issue resolved. Run the putty and enter your COM port name like COM5 and start its session.

Below are the commands to configure the web access of  Cisco AP

Cisco access point configuration

ap>en

Password: Cisco (this is case sensitive)

ap# config t

ap(config)# interface GigabitEthernet 0

ap(config)# ip addr 172.16.1.2 255.255.255.0 (or whatever IP you need on your production network)

press ctrl+z to exit config

type wr to write the config

Then access the ip address in your browser and configure the Access Point. Default username/password is Cisco

- Click on the left tab option Easy Setup and select Network Configuration 

We already configured the network configuration from the terminal. Now we have to configure the Radio configuration for wireless access.

Enter your desired SSID and disable the Universal Admin mode. Under Secuirty it is your setting to set this up. In my case I am getting my wifi access from firewall and it is on MAC based so I select the No security.

Select the second tab Network and select the Radio0-802.11N 2.4Ghz under Network Interfaces and enable the radio under Enable Radio and save the settings.

Now connect to your wifi SSID.
