My wireless card worked out of the box, but now I want to turn the maschine into an access point so I followed these guides

Unfortunately, iwconfig eth1 mode master returns Error for wireless request "Set Mode" (8B06) : SET failed on device eth1 ; Invalid argument. and according to iw list supported interface modes are IBSS and managed.

Strangely using Windows' hosted network works fine.

My Network Controller is Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01).

IBSS means ad-hoc, that is computer-to-computer: http://en.wikipedia.org/wiki/Independent_Basic_Service_Set

With 802.11, one can alternatively set up an ad-hoc network of client
devices without a controlling access point; the result is called an
IBSS (independent BSS).

Therefore, your hardware and driver combination supports master mode; that is computer-to-access point as well as ad-hoc mode; that is, computer-to-computer. Master mode is evidently unsupported.

  • unfortunately ad-hoc mode will not work for me because I want use an old android device and a handheld that won't support ad-hoc connections. But are you saying that I should just follow the instructions in the guides? – user28061 Jun 17 '13 at 16:36
  • installing the open source driver (wireless.kernel.org/en/users/Drivers/b43#Ubuntu.2FDebian) helped now iw list shows AP – user28061 Jun 17 '13 at 17:33
