How to completley deactivating Wlan?

    I am using my LinkSys WRT54G (Rev. 2.2) with the latest Firmware HyperWRT 2.1b1 at 1mw.I tested at 0mw (manual) and the Wlan connection is working too.
    But most of the time I am using a LAN connection to the router.
    Is it possible to deactivate the Wlan on the router completely?

    Yes it is possible: just set the wireless network mode to disable. You don't need to change transmit power.

    Well, thank you for this hint! It was obvious, but I am a Rookie. Sorry.
    But the lamp in the front of the Linksys is still green.
    Is it really out? Is there any simple "trick" I can test if the Wlan is really completely out?

    How to tell if your router WLAN is off - install netstumber on your PC and look for wireless signals

    I believe if you SSH'd or telnet'd into the router and issued the following command:

    ifconfig br0 down

    That would have the desired effect (shutting down the WLAN)

    I started a command shell in the aministration Tab of the configuration menu and entered:
    ifconfig br0 down

    -> ifconfig: not found

    Thank you for your help dellsweig!
    I give this command:
    /sbin/ifconfig br0 down

    -> "SIOCGIFFLAGS: No such device"

    the seccond time I try this I have to make a reboot, because the router hangs.

    Isn't br0 the bridge with both the LAN vlan and the wireless eth interface. I forget if the wireless is eth0 or eth1 but wouldn't you want to take that down not the entire bridged interface.
