Build Wizards - can you build this driver for me?

[BinaryJay]

I feel like a dunce but I have been unable to get this driver for my wifi built...

http://www.realtek.com.tw/downloads/dow ... #RTL8192SU

First, I had to change the Makefile so that it stops using uname -m to determine the source folder and replaced it with just "arm"... that got it looking like it might start working...

Reason I'm wanting to try this is because, although the standard kernel firmware (r8712u) for the device included with Arch is working fine as a client, I cannot get it working with nl80211 and can't use it for it's intended purpose with hostapd.

Here's as far as my attempt has got me... what's going on here?

I'm googling on the " error: implicit declaration of function init_MUTEX" now, but maybe somebody just knows what the resolution is already around here.

Edit... well I guess I may have solved this myself...

I changed the init_MUTEX in the offending file to sema_init ... still not sure what's with init_MUTEX on this kernel/gcc version.

This driver is available in the current kernel, but not built.
It's in staging, perhaps it can be built in next build?

[BinaryJay]

Just in case anybody else stumbles on this page - the latest driver directly from realtek makes no difference. It works fine as a wext driver (which wpa_supplicant can use, but hostapd cannot) but not as a mac80211 driver.

There is some hope, the driver builtin to Kernel 2.6.37 r8712u looks to be still under development and I found some patches kicking around the last few months that state that adding mac80211 support to it is on the list.

http://help.lockergnome.com/linux/PATCH ... 31134.html

@@ -3,8 +3,6 @@ TODO:
- switch to use LIB80211
- switch to use MAC80211

Hopefully the developer is close to wrapping that up. I have two of these devices and no use for them as clients, really.

[pepedog]

Ath9170 and P54 based chips work nice with hostapd, P54 is more reliable, other has regdom problems

I don't know that n will work as an access point. The ath9170 is n as a client, but (using carl9170) up to g only

I bled a few more dollars and ordered a Ralink 3070 based adapter to experiment with.

According to LinuxWireless.org, rt2800usb is looking better than the realtek drivers at this point.

Appears to be mac80211 ready, and confirmed monitor mode but question marks on AP support. I guess it will be touch and go but even if it doesn't work now it is closer to my goal than r8712u. Unfortunately Ralink 3070 is only 150mbps, but it's better than going all the way back to G.

If I can get everything working with the 3070 for now I'll be happy, and later on if the rtl drivers mature I can switch over. I just want to dump my router. Hopefully the chinese no-name USB ethernet adapter I ordered won't have any problems, though I expect that to be a lot easier to deal with than the wifi... from what I read it's chipset should be good to go in 2.6.37 (or even earlier) but with my luck it will have some chipset by some unheard of company in it as opposed to what was reported online.

[pepedog]

Will be interesting to see if N works as an access point

FYI, I successfully got the new adapter which is a Rosewill RNX-EasyN1 to work with hostapd in AP mode. I was able to connect to it, but only as far as to get access to the plug itself because I am having problems understanding setting up the bridge to eth0 properly.
