I need the driver to set my antenna as an AP, but build from svn fails:

Re: AP mode for zd1211 won't build on 2.6.31.6

You obviously did not read any of the archive postings, nor look at the web site in details. The
vendor-derived driver has been defunc for a while; most people use the in-kernel rw driver, others use the
vendor driver + my patchset.

Grep the latest vendor tar ball, 

http://www.kernel.org/pub/linux/kernel/people/mcgrof/zd1211/

then grab the corresponding patch set:
http://htl10.users.sourceforge.net/patchsets/

Re: AP mode for zd1211 won't build on 2.6.31.6

Executive summary: thanks for the links. I built the driver but master mode 
doesn't look supported still:
gandalfthegrey:/usr/src/zd1211# iwconfig ath1 mode master
Error for wireless request "Set Mode" (8B06) :
    SET failed on device ath1 ; Invalid argument.

Back to your mail:

Well, I did spend about 1H looking, but:
1) which web site?
Isn't http://linuxwireless.org/en/users/Drivers/zd1211rw the canonical
site?
If so, unless I read wrong it states nothing of the site you gave below.

2) I searched all archives I could find with "zd1211rw master mode"
on google and it brought me to this list, although I didn't find any
posts I should have found you are referring to.

Even http://lwn.net/Articles/186311/ points back to
http://zd1211.ath.cx/wiki/DriverRewrite which brings one here
http://sourceforge.net/projects/zd1211/develop.

Is there a way to seed google with the right answer and get it on
http://linuxwireless.org/en/users/Drivers/zd1211rw?

Interesting - here used to be some info explaining the three at :

but now that's gone and get re--directed back to the download site.

You need to ifconfig up first. Nothing works before ifconfig up.

Re: AP mode for zd1211 won't build on 2.6.31.6

Thanks for your replies and pointer to the code that builds.
Unfortunately, after I bring it up, it doesn't seem reliable enough to
allow connections.

In a nutshell, my phones see the AP. Sometimes I am able to connect to
it but not get an IP. Very rarely I get an IP, and my machine usually
ends up crashing some time around that.

One noticeable thing is that 
Tx excessive retries
in iwconfig shows a few hundred errors per second.

Is the AP code working and stable for you?

Below is the code I wrote:
----------------------------------------------------------------------------
#!/bin/bash

IF=ath1

rmmod zd1211rw
sleep 1

The code works alright for me for the 6 months I used it as my main AP - until the machine to which it is connected
to die of old age. (it is ust under 10 years old, so way past its expected lifetime).

A couple of comments: I now remember that I found that I need to run at least an 'iwlist scan' or do something
*on the AP* before a client can connect. Otherwise it is not visible to a client.

> One noticeable thing is that

Hmm, I don't have that.

> Is the AP code working and stable for you?

Yes, can run it for days. But yes, the AP machine sometimes crashes after a few days.

Different code base - we have been talking about the vendor driver, not the rw driver. The rw driver will
never support AP mode - see the discussin a while ago on linux-wireless mailing list. (apparently the
vendor driver is not being entirely correct about power-saving issues, and the hardware itself does not
have the required spec to implement power-saving support in AP mode properly according to the 802.11
spec, so the kernel developers have decided that if it cannot be done properly, it will not be done at all).
This may be what the problem with iphone client going to sleep and the AP going funny.

Have you seen any support in mainline yourself?

The 'someone' is possibly me... AFAIK I am the only one maintaining a patch set to keep the vendor zd1211b
driver working with current kernels.
(for the reason that the rw driver is not adding AP support any time soon, and the AP mode in the vendor driver
sort of works now).

oh my, I don't know what 'someone' means here. That word does not
belong.

yes. Sorry that my dodgy sentence possibly meant otherwise.

Thank you, I think I had misspelled networkmanager when I was doing the
