WiFi - issues of the new Moto/TI drivers and firmware

[GoogleCodeExporter]

0.03-10.10.21b

I have a problem with WLAN like many other users of GOT 2.2.1 and CM6, too. My 
connection drops frequently and the speed is very low. It just happens with 
specific router / Milestone configurations, but it did'nt appear on 2.36.

Could it be possible to fix it, e.g. with replacing some WLAN-modules / -files 
with old ones to get it working again? Because the situation is very 
frustrating...

Currently know workarounds (on AP side):
- switch from WPA2 to WPA
- switch from TKIP to AES cipher
- don't use the mixed mode
- disable N mode

Interestingly enough, some people find the new wlan firmware from the 2.2.1 
test firmware better than the old one...

After looking at that thread about recompiling the drivers at xda-developers: 
Is the other way round also possible? I mean would it be possible to compile 
the old (in my opinion better) drivers for the kernel of our 2.2.1 firmware?

I also see the same problem... hard to get connected and intermittent 
connection. I Found the solution and looks like now time to share with you 
another tweak from me.

Fix unable to connect to wireless b/g/n. Even mixed mode works now.

1) Download wififix.sh that i attached
2) Put under /sdcard/OpenRecovery/scripts/wififix.sh
3) Boot into RECOVERY
4) After you be inside OpenRecovery, click on "Run Scripts"
5) Choose wififix.sh

DONE !

Fix intermittent connection

1) Download dnsfix.sh that i attached
2) Put under /sdcard/OpenRecovery/scripts/dnsfix.sh
3) Boot into RECOVERY
4) After you be inside OpenRecovery, click on "Run Scripts"
5) Choose dnsfix.sh

DONE !

It works for me and hope it works for you all.

Thanks!
I've been actually including the default.prop with the dnsfix content in the 
previous CM6 releases, so I take it as a notice that it's missing now :).

Those who experience the WIFI issues, please test whether the disabling of the 
802.11n (HT_Enable=0) in tiwlan.ini helps (wififix.sh).

The wifi-fix indeed fixed the wifi-problems I had with my FritzBoxes!

this was not a problem for me on "0.03-10.10.27 6.1.0-RC1".
But its happening on "0.03-10.10.31".
I have since roll back to 10.10.27.
will try the Wifi fix and see if it works.

with the last build (0.03-10.11.08) mi milestone no longer detect my wifi 
network (WPA-PSK+WPA2-PSK). It doesn't event detect that there is a wifi 
signal, i didn't try with another wifi newtwork yet, but the fact that it show 
no available AP it seems like as the wifi module remains turned off.

Since the version 10.10.31, the option in /system/etc/wifi/tiwlan.ini:

HT_Enable=1                     #0=diable 802.11n support / 1=Enable 

Has been changed to HT_Enable=0 (N support disabled), as it was causing 
problems to many users, whose WIFI AP has been set to allow both G and N 
connections.

If it is causing you problems, you can set it back to HT_Enable=1 (or change 
your wifi AP settings to allow also the G mode).

HT_Enable is on line 186

yeah i know that, but with the 10.10.31 build all was fine, just with this last 
build this issue appears.
If i'm the only one having this kind of problem, sure it depends from me. I'll 
investigate on it, thanks.

thshine

I'm having the same issue as you..i tried the scripts but its not helping..
I then tried changing the HT_Enable to 1... this fixes my problem..!! :D

Is it because I'm using fiber optic connection? no idea.as long as its working 
now..
i'm happy.. :D

AFAIK putting HT_Enable to 0 is the right way to solve the problems. Hardware 
of the Milestone is not capable using 802.11n.

I think, that the problem has something to do with:

https://forum.openwrt.org/viewtopic.php?pid=114504

"...The  cause is that the wireless driver in many of the custom ROMs is 
WiLink_Driver_6.1.0.0.131, which incorrectly sends two WPA2 RSN IEs that are 
different. It uses the value of the PTKSA from the AP to generate the PTKSA and 
GTKSA settings in the RSN capabilities section for the first RSN IE, but just 
uses 0 for the second. If WMM/WME is enabled on the AP, the AP sets its PTKSA 
to > 0, causing the Droid to respond with one RSN IE with non-zero values. But, 
hostapd uses the second RSN IE, notices the mismatch, and drops the 
connection..."

My logs on my wifi router confirm the problem:

Thanks, it's a good tip - disable WMM/WME on your AP router.

Btw., there are lots of similar wifi issue reports also from the 
Droid/Droid2/DroidX users... go figure.

At this point, without the proper kernel sources, there seems to be no chance 
to fix the tiwlan driver.
