How to connect Aironet 3602i AP to Linksys CM100 Cable Modem?

[truongduy1901]

Currently, my D-Link DIR-625 Router is connected to Linksys CM100 Cable Modem.

I want to replace the D-Link Router with a Cisco Aironet 3602i Access Point. Apparently, simply connecting the 3602i AP to the cable modem through Ethernet port doesn't work. I've already configured the 3602i AP for wireless surveying and created 2 SSID's.

What do I need to do next to connect Aironet 3602i AP to Linksys CM100 Cable Modem for internet connection?

Ok that's even better.

Now will do this. 

1. Save the current configuration to AP flash"

ap#copy startup flash:3600-backup.txt

2. Erase the configuration & reload the AP

ap#erase startup-config

Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]

[OK]

Erase of nvram: complete

AP#reload

3. Apply the below configuration. Make sure you add the correct password  instead of <SSID_PASSWORD> section below.

conf t
hostname AP01
!
dot11 ssid Gemini
   authentication open
   authentication key-management wpa version 2
   guest-mode
   wpa-psk ascii <SSID_PASSWORD>
!
interface Dot11Radio0
 encryption mode ciphers aes-ccm
 ssid Gemini
 no shutdown
!
interface Dot11Radio1
 encryption mode ciphers aes-ccm
 ssid Gemini
 channel width 40-above
 no shutdown
!
interface BVI1
 ip address dhcp
!
end
write memory

Will give it a try to this fresh configuration & I think it should helps

Thanks Rasika!

I think I made a mistake during the process of enabling my AP to be a DHCP server (in order to telnet in to the AP). The ip address and defaut router address mismatched which, I'm pretty sure, was the source of the problem.

Glad to hear that finally you got it working. Yes your AP not to be DHCP server for the client as it is provided by your modem/router. 

Having a simpler configuration always helps

Thanks for rating as well. Have a great weekend.

Hi Rasika,

What is the proper way to change the SSID and its password without having to reconfigure everything from the beginning?

Can I change them via the GUI?

[Rasika Nayanajith]

Once you create a SSID, you cannot modify its name. So best way to change it by creating the new SSID first & advertise it on your radio interfaces as appropriately. Here are the CLI commands to do that 

dot11 ssid XYZ
   authentication open
   authentication key-management wpa version 2
   guest-mode
   wpa-psk ascii <XYZ_SSID_PASSWORD>
!
interface Dot11Radio0
 mbssid
 ssid XYZ
!
interface Dot11Radio1

 mbssid
 ssid XYZ
!

Once you successfully connect to the new SSID you can remove the old SSID from your AP.

 no dot11 ssid ABC

In GUI as well you should able to do same (creating a new SSID & removing the previous). Here is a config guide which shows GUI options

[truongduy1901]

interface Dot11Radio0
 mbssid
 ssid XYZ

When I used the above command to create a new SSID for Dot11Radio0, it gave me an error "Dot11Radio0: Guest-ssid already existing on ssid Sagittarius".

Hi,

Pls attach your AP configuration as a text file (simply copy & paste your config to a text file)

Then I can suggest the exact modification required
