Hello,

I am trying to get hostapd up and running on my Soekris net4521 board,
until now without much success.  One of the problems might be that I
am completely at a loss which version of hostapd is supposed to work
together with which driver.

Any help about which combinations of hostapd and device driver have at
least a chance of working together would be more than welcome.

I tried the following PCMCIA cards, device drivers and hostapd
versions:


*** LinkSys WRT54GL (broadcom 4318) ***

I tried the following drivers:

1) CONFIG_B43 in current wireless-dev
2) CONFIG_BCM43XX in current wireless-dev
3) CONFIG_BCM43XX in 2.6.23-rc3
4) CONFIG_BCM43XX in 2.6.22.5

I can succesfully use wpa_supplicant with this card, e.g. with driver
1) above, but there are some error messages.  On the console:

    ioctl[SIOCSIWAUTH]: Operation not supported
    WEXT auth param 4 value 0x0 - ioctl[SIOCSIWAUTH]: Operation not support=
ed
    WEXT auth param 5 value 0x1 - Internet Systems Consortium DHCP Client V=
3.0.4

    For info, please visit http://www.isc.org/sw/dhcp/

dmesg output (note the bbatt error):

    pccard: CardBus card inserted into slot 1
    PCI: Enabling device 0000:05:00.0 (0000 -> 0002)
    PCI: Setting latency timer of device 0000:05:00.0 to 64

    b43-phy7 ERROR: bbatt(11) >=3D size of LO array
    ...

lspci output for the card:

*** Netgear WG511 (prism54) ***

I tried the following drivers:

5) CONFIG_P54_PCI in the latest wireless-dev
6) PRISM54 in the lates wireless-dev
7) PRISM54 in 2.6.23-rc3
8) PRISM54 in 2.6.22.5

I also found hints to some driver called "islsm" on the internet, but
I did not find a place to download this.  Also I only found
contradicting information about whether this is USB only or not.

Again, I can successfully use wpa_supplicant with this card (at least
with driver 5 above).

*** hostapd ***

I tried the following versions

a) 1:0.5.5-3.1 from the current Debian/stable distribution
b) 0.6.0 from the hostapd web page
c) current git from http://w1.fi/hostap.git


*** the problem ***

I did not find any combination of a hostapd version (a, b, or c) and a
device driver (1, 2, ..., 8) which would work together for me.

Example: combination 1c (CONFIG_B43 in wireless-dev, current
http://w1.fi/hostap.git) gives

I tried many other combinations of drivers and hostapd version but
nothing worked wor me.  Does anybody have any hints about this
combination of driver and hostapd currently have the biggest chance of
working together?

Many thanks,
Jochen
