Cisco aironet 1200 and Virgin Broadband

cjones · 07-12-2008, 09:23 AM

Hi to all, new to this site but hope someone can give me a helping hand...
Previous to this problem..
I currently have a broadband connection via Virginmedia (UK). Virgin provide a modem that fits to the Cable feed. There is an RJ45 cable that then connects to either a PC, Mac or Wirelss ap. At the moment I have a KCORP KLS-757 which works fine if your sat on top of it. Not much good for roaming around the house though.
It was a fairly simple setup.
Got into the KLS, gave it an IP and range and made sure it could obtain an IP from the Router.
Connected the RJ45 to the WAN port. Switch on the Virgin Router (wait for config) then turn on the KLS AP
Works! I'm using it now... But, I want to upgrade to this Cisco Aironet 1200 thats a bit tougher.
I've got full access to the Cisco interface but cant for the life of me figure out how to get the thing working.
I've had it connected via a BT Voyager Router and it worked right away, just changing the IP but it had no security.
Virgins Routers do something strange. You cant just get the IP of the router and and put it in the gateway on the AP.
I've tried alsorts turning it on and off using patch cables and netgear switches as a go between but cant get any internet through it at all. Then theres the impossible task of figuring how to put a simple WPA security on it.......
If there is anyone out there that has managed to get the Cisco Aironet 1200 working through a Virgin Media Connection I would love some help please.
Thanks in advance to all those that can assist

When connected directly to the Virgin modem, then again when connected to the Cisco router, please post this.

Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Hi. The Cisco Aironet's are a lot more complex than your standard AP. You need to add the appropriate command into the modem connected interface to tell the Aironet to obtain it's IP address by DHCP. The best thing I can suggest at this stage is to follow this link to the Cisco web site and a list of configuration guides for you Aironet depending on the version of software (IOS) installed. If you are unsure of your version, go with a 12.2 or 12.3 version as a guide. You will need a Cisco console cable to connect to the Aironet and perform primary configurations. Once you have IP connectivity to the Aironet, you can use a web based GUI to configure your security etc.

Hope this helps.
