WiFi access point with iwl3945

Hi,

I'm trying to set up my laptop to be a wireless access point. It has
an iwl3945 card. I followed the "Atheros Ath5k Wireless Access Point"
article on gentoo-wiki.com[1] before realizing that it was Atheros
specific.

Part of the setup uses hostapd[2]. Looking at this, it's not
immediately clear that iwlwifi is supported.

Does anyone know whether it's possible to use hostapd with iwlwifi
drivers? Is there an alternative access point software I can use?

Thanks,
Mike

Sorry, your hardware doesn't support working as an access point.

Except of buying new hardware, I think your only chance is to run in
ad-hoc mode.

Thanks for clarifying. No wonder I couldn't find any tutorials
specific to the iwlwifi driver.

Gentoo-wiki is a mess. :(

If only the people who wrote their separate articles about building
APs with madwifi [1] and ath5k [2] had thought to improve and
contribute to the pre-existing "wireless access point" article:

http://en.gentoo-wiki.com/wiki/Wireless/Access_point

That explains very clearly (as has Florian) that the hardware needs to
support "master mode" and also why. The explanation of setting up the
iptables / bridging / dhcpd / &c should not need to be repeated on
multiple pages.

I started that page originally, but this was perhaps as much as 5
years ago. At that time it documented how to produce a basic
installation with simple explanations in order to make it "easy" for
someone who was even just a little command-line literate. It has
actually changed remarkably little in some respects, but I doubt it is
any longer consistent or fully accurate. It actually claims that the
ipw3945 does do master mode - I assume this is a different driver for
your card? - but Googling leaves me dubious; I see the claim repeated
other places without the poster actually appearing to succeed.

Stroller.
