    wireless master mode !!

    Hello .. im desperately triing to let my laptop to work as access point ( and then forward trough my wired card). I read several howtos but i fail almost immediately on this command:

    root@hyperion:~# iwconfig eth0 mode master
    Error for wireless request "Set Mode" (8B06) :
    SET failed on device eth0 ; Invalid argument.

    note that wireless card is detected and work correctly in managed mode, the only think im unable to enable master mode ( even ad-hoc mode is accepted, but its not what im aiming for ). I read also that some card are not capable to work in this mode but i triied with 2 laptops ad even with a usb wireless card, and i get always the same result. Its possible that im so unlucky or there is something i missed ? its just a driver problem and i should try another driver even if card seems work correctly ( in managed mode).

    Any hint will be really appreciated.

    This may be a stupid question but is eth0 definitely your wireless card? I know that on my comp eth0 is my ethernet card and wlan0 is the wireless (look in kmenu>system settings> network settings if you are unsure).

      Is there a specific reason for doing it on the command line?

      I would first open knetworkmanager - it should be there as an icon in your taskbar anyway in the form of a plug from lan cable - if you are plugged in, that is.

      Right click on that and enable wireless. Does it work?

        @marshallbanana

        yep .. for unknown reasons my wired card is eth1 and wi-fi card is eth0. SInce its not a big problem anyway i never cared to rename the deviced. Anyway heres some info to prove it:

        root@hyperion:~# iwconfig
        lo no wireless extensions.

        eth1 no wireless extensions.

        I think you dont understood the problem. I dont want to connect to an access point. I dont want to "find" an essid. What i aim is that my laptop provided essid and an access to other wi-fi devices.

          Sorry mate - no, I didn't read your post properly/understand your problem. I'll be following this thread with interest though, as I know nothing about what you are planning to do...

          Good luck

            Re: wireless master mode !!

            Seems i have no chance to do it. there are not many good howtos onthis topic, and most of them are quite old. but what i got is that not all devices are capable to run in master mode, and even if the device can, the linux driver often was not made to enable it ( probably the first goal was to use it in standard mode and they not cared much alternative usage).

            Anyway:
            in both my laptops have intel 2200GB chipset for wifi, and the linux driver dont support master mode, ndiswrapper seems also not capable to enable master mode ( at least i read so). the usb wi-fi device its a DWL-G122 and also this cant be used in master mode ( at least with linux). >

            So i think i have to give up.
