Re: madwifi, F9, atheros 5413 cards

Thanks Martin for your reply.

I tried the recent madwifi-hal but still the same problem. I think the
problem is somewhere else because in dmesg it can be seen that ath_pci finds
correct chipset and loads properly. There are no error there.

I added a vista laptop (intel wireless card) to the adhoc network and ran
wireshark on it. When I ping the laptop from F9 machine, I can see that ARP
arrives at laptop and laptop replies it with its MAC. But then that reply is
never accepted by F9 machines. Its like, it drops those packets somehow and
Rx packets in ifconfig ath0 remains 0 (there are many Tx packets though).

Is there some preset security in F9 blocking this? It says an unsecured
network in Vista laptop. What else it can be because same think on Ubuntu
runs just fine..

Any pointers??

I have an AR242x. Livna madwifi didn't work at all.

Solution: Download madwifi-hal-0.10.5.6-r3861-20080903, compile and

If someone can please help. same cards AR5413 (ar5006x) work with
madwifi-0.9.4 on ubuntu but does not work on Fedora. I tried upgrading
kernel too but still no luck.

ath5k which comes built in in F9 works with this card. Initially some
howto
mentioned to blacklist this module before loading madwifi's ath_pci.
Isn't
ath5k still in starting phase? Has someone tried to use it with ar5413
(ar5006x) cards?

thanks,

Hi All,

I am trying to use Adhoc mode with AR5413 card (5006 chipset) with
following -

#uname -a
Linux localhost.localdomain 2.6.25-14.fc9.i686 #1 SMP Thu May 1 06:28:41
EDT 2008 i686 athlon i386 GNU/Linux

There are 2 machines running F9/madwifi and having same cards in adhoc
mode. (livna - madwifi-0.9.4-1.lvn9.i386,
kmod-madwifi-0.9.4-31.lvn9.i686,
kmod-madwifi-2.6.25-14.fc9.i686-0.9.4-31.lvn9.i686,
madwifi-devel-0.9.4-1.lvn9.i386)

In adhoc mode, they associate with each other (same cell ID) but are not
able to further communicate. ath0 interface created on top of wifi0 does
not
receive any packets but wifi0 do receive. I am not able to ping one from
another. routes are set.

On both machines ath0 RX packets remains 0 and I don't know why is this
happening!!! Can someone please help..

I think that there no problems with ath_pci loading as can be seen -

#dmesg

In last 3 lines, I overdid security because initially I thought the
problem is due to authentication. I don't want any security at this
point.

[ Other tests -
- the same card works in managed mode and connects to my building's WLAN
AP. This makes me wonder more what I doing wrong.
- same cards with madwifi 0.9.4 works on Ubuntu in ad-hoc mode which
shows
that something in Fodora is going wrong. I really like F9 and really
don't
want to switch to ubuntu. ]


Any help is really appreciated.

Thanks in advance,
phm
