Hey,
how do I disable draft n / 802.11n on Quarx' CM11?
I can't find tiwlan.ini in /system/etc/wifi so what to do??

Thx.

SOLUTION: http://xdaforums.com/showpost.php?p=50426027&postcount=7

Code: 
/system/etc/wifi/hostapd.conf >
ieee80211n: Set to 1 to enable 802.11n support, 0 to disable it
Changing this line from g to n helped cyrus:
Code: 
hw_mode=g

I guess you probably know about alternative firmware for FritsBox routers, but if not, have a look at this site: http://freetz.org/
Perhaps this firmware will let you better configure your router.

Thanks. Yes I do know about that but modifying the router is not an option since I don't have access to all routers I can use as an access point, thats why I pointed out that I can't change the router settings. I need to disable it on the device and that was possible under CM7.

You want to disable the n mode because of the poor performance of Wi-Fi? I ask because I too have poor Wi-Fi performance but no matter what I do changing channels, modes, etc. my Defy doesn't want to download for example a nightly from Quarx site. Is downloading ~5% then stops think then download again and so on. With other 2 phones(Samsung and an old HTC hd2) this is not happening the download is continuous.

No, reason is that sometimes the Defy seems to interfere with other clients in the network (Macbook, other smartphone etc.). Sometimes I do have interupted downloads though.

But I think I just figured out where to change that:
Code: 
/system/etc/wifi/hostapd.conf > hw_mode=g
.
If that is correct, it is already in a legacy mode and doesn't use 802.11n.
There seems to be another setting:
Code: 
ieee80211n: Set to 1 to enable 802.11n support, 0 to disable it
so I will try disabling that tonight. Exciting!! :)

well that shouldn't be possible! :eek:
Reason: The N setting shouldn't be set there but there:
Code: 
ieee80211n: Set to 1 to enable 802.11n support, 0 to disable it

Maybe you disabled it alltogether because the switch doesn't exist and as a fallback the device uses 802.11b now... I don't know. If it's good, it's good! :)

It's not solving the problem.
After investigating more I have seen that after a reboot the Wi-Fi performance is good ~2Mb/s. But as soon as the device enters in deep sleep the download goes down at 500kb/s and is interrupted a lot. Can anyone else could confirm that?

I have tested with quarx2k.ru site.

    I can't answer, because I don't know. But may I ask why do you want to do this?
