What you need to do is create a bridge-group virtual interface (BVI) to link the wireless to the switchports so all your computers can talk and have internet.

Do you know how to do this or do you need a config?

 

by: railitPosted on 2008-10-02 at 05:22:05ID: 22623404

I would appreciate it if you could provide me with a sample config.

 

by: CaoiltePosted on 2008-10-04 at 02:46:34ID: 22640107

Have a look here http://www.ceenet.org/workshops/lectures2004/Erkki_Kukk/labs/wireless_vlans.pdf

a good starter point for multiple VLAN's - it looks like you are missing a BVI and VLAN20 configs.

The above is for a dedicated AP but the config for he radio, BVI and Eth ports are the same on your kit

 

by: PugglewugglePosted on 2008-10-04 at 21:38:36ID: 22643437

Hi railit,

The following commands create a bridge group and assign IPs to your default VLAN 1 and your guest SSID.

Let me know if this helps!

I was able to obtain a wireless connection with the commands provided by Pugglewuggle.

However, the computers when first booting up for the day, always ask for the password from my isp, Earthlink.
Is there a command to either include the password or bypass its requirement?

thanks in advance
