Autonoumus AP configuration connection to Cable modem. using AP . AIR CAP3702I-A-K9

[Seroj Hacopian]

Hi,

interested in configuration of  AIR CAP3702I-A-K9 autonomous documentations to connect to a cable modem,

I did change the OS from capwap to Autonomous.

Below basic configuration will work as long as your modem provides DHCP IP. Modify SSID_Name & Password appropriately

conf t
hostname <AP_HOSTNAME>
!
dot11 ssid <SSID_NAME>
authentication open
authentication key-management wpa version 2
guest-mode
wpa-psk ascii <SSID_PASSWORD>
!
interface Dot11Radio0
encryption mode ciphers aes-ccm
ssid <SSID_NAME>
no shutdown
!
interface Dot11Radio1
channel width 40-above
encryption mode ciphers aes-ccm
ssid <SSID_NAME>
no shutdown
!
interface BVI1
ip address dhcp
!
end
write memory
!

Hi

Since radio interface encryption not configured prior to SSID config, this may come.

Try below missing lines again & see if that works

dot11 ssid Cisco
authentication key-management wpa version 2
wpa-psk ascii <SSID_PASSWORD>

I tried to configure DHCP scope for the clients from the GUI who are attempting to connect

and found no parameters for configuration.

wireless clients need ip addresses from AP DHCP server to connect.

does need to be configured from command line?

Thanks

[Rasika Nayanajith]

You can do this via GUI or CLI.

Here is an example config in CLI. You need to configure correct gateway (should be the IP of your DSL modem IP) & proper DNS server info. 

ip dhcp excluded-address 192.168.21.1 192.168.21.10
!
ip dhcp pool VLAN21
network 192.168.21.0 255.255.255.0
default-router 192.168.21.1 
dns-server 8.8.8.8

Note that AP cannot do any NAT, so your DSL modem should do this. Ideally you should define DHCP on your DSL modem
