AP Aironet 1240AG Configuration Problem

sonuwd · ‎11-30-2016

Hello guys,

Before I start I would like to say that I am New to Cisco and never configure any access point or router before. I only used Linksys and TP link router and access point before. So please advise me as a new person.

I heard a lot of good things about 1240Ag access point and bought one for our home use. The access point is connected with a Virgin Media cable router via Either net cable and I have an IP address to use the web browser.

1- When I Login and try to use GUI and enter "Express Setup" to change Access point name and give it a static IP address, the "Apply" button doesn't work at all.

2- Then I enter into Express Security, assign a SSID and change the other settings accordingly, when I click on "Apply" button, it doesn't work. I doesn't even lit.

I have Enabled both Radio0 and Radio1 from Network Interface Settings, but since I can't assign a SSID to this AP, the Radio0 and Radio1 doesn't activate.

Product: AIR-AP1242AG-E-K9

Software File Name: c1240-k9w7-tar.124-10b.JA

Software Version: 12.4(10b)JA

Boot Loader: 12.4(13b)JA

I bought this Access point from friend and it was working perfectly in their office before they upgrade to a new one.

I have change the browser, laptop and even try to do settings from iMAC but no luck.

I read in this forum that I can do settings through Telnet (which I installed) on Windows 10. So could please tell me how to configure AP on Telnet from scratch? I just need the correct commands to configure SSID and WEP thats it. Just for my basic WLAN needs.

Thanks in advance for help

Edited: I noticed in forum that almost all GUI Guide has Radio0 and Radio1 settings in "Express Set-up" but I only have AP,IP and SNMP Community settings.

If you get CLI access of the AP you can try below. 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
encryption mode ciphers aes-ccm
ssid <SSID_NAME>
no shutdown
!
interface BVI1
ip address dhcp
!
end
write memory

Thanks Rasika for your reply,

What if I create a Config.txt file by copy and paste this text and make the changes to SSID and password and upload it through GUI interface, will it help?

I have the access to AP through Telnet and SSH. but when I type the text it says invalid command.

You need to go to enable mode first and then try it.

ap>en (you need to enter enable mode password - default is Cisco)

ap#config t

You my friend are the "STAR". My AP is not only transmitting wifi signals its also faster than I thought.

Now tell me how to recover an another AP which was turn off while updating the firmware and now there is only Red Flashing light.

Good to hear that :-)

Refer below guidelines for that AP you had problem getting upgraded.

If neither the GUI nor the CLI is available with sufficient privileges, complete these instructions in order to use the Mode button:

Disconnect power from the AP.

Disconnect the power jack for external power or the Ethernet cable for inline power.
Press and hold the MODE button while you reconnect power to the AP.
Hold the MODE button until the Status LED turns amber, and then release the button.

The Status LED turns amber in approximately 1 to 2 seconds.
After the AP reboots, reconfigure the AP and use the web browser interface, the Telnet interface, or Cisco IOS Software commands.
