which hostapd version for which wireless driver

which hostapd version for which wireless driver

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 supported
    WEXT auth param 5 value 0x1 - Internet Systems Consortium DHCP Client V3.0.4

dmesg output (note the bbatt error):

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

I tried hostapd for the first time last night and it worked with my
old PII laptop and b43. So it should work :)

I used latest git for both the kernel and hostapd. My notes here:

http://marc.info/?l=linux-wireless&m=118823232032439&w=2

I did not issue these commands, but I don't know if it makes any
difference in practice.

>     root@funk [~] ifconfig wlan1 up

I think I didn't do this, but can't be sure anymore.

My advice is to double check that you are really using the correct
hostapd compiled for the kernel you are running. And did you remember
to do make clean for hostapd between compilations?

Both git trees (wireless-dev and hostapd) work fine together :)

That's the one you want.

No chance of getting these working.

That's expected, ignore it.

Also known and can be ignored.

I don't think that supports AP mode.

Nor do those, HOSTAP driver is the one you'd want here, along with the
hostap hostapd driver.

Don't do any of that, hostapd configures everything.

Do that after starting hostapd while the interface was down.

You need to start hostapd while the interface is down ("ip link set
wlan1 down").

Ok, it works now for me.  Knowing which of the many combination to play
with
helped to focus my efforts.  Thanks a lot for your help.

I tried this only shortly, but I am not so sure about this one.  The hostap
driver states that it is for "Prism 2/2.5/3 wlan cards".  Isn't there a
difference between this and prism54?

Ok, it does now.  My problem turned out to be the "hw_mode=b" in the config
file.  When I use "hw_mode=g" instead, everything suddenly starts to work
:-)

Many thanks,

Many thanks, I also got this combination working now.

All the best,
