Some people who are using the Motorola Defy ME525 have the WiFi connection issue, it usually happen with the official roms, such as Android 2.2 or the latest Android 2.3.4, they can not connect to the Wireless Router, or the WiFi connected successful but just can not access the Internet, if the other devices such as PC or Laptop WiFi is working normally, and your Wireless Router is working under 802.11n mode, you should do some modification in your Defy Android system.
The problem is caused by the WiFi hardware configuration, there is a WiFi problem in some Motorola Android phones, some of them can not working well with the 802.11n WiFi network, it could lose connection or hard to connect to those WiFi network, one of the workarounds is disable the 802.11n function on Defy, use the 802.11g mode. How to change the 802.11n mode to 802.11g mode?
You need to root Defy first, as we need to modify a system file.
Follow the steps:
1. Use the Root explorer, open this file path: “/etc/wifi/”,
2. Use the file editor to open the “tiwlan.ini”.
3. Find this two lines below, change the value if it is not 0.
HT_Enable = 0 # 0=diable 802.11n support
BurstModeEnable = 0 # 0 - Disabled 1 - Enabled
4. Save the file, then reboot your Defy.
Try connect to the WiFi again, every should working correctly. though give up the 802.11n mode, We don’t need the 300Mb/s speed on Defy, so this method has no side effects.

Hi, I applied the change to the file “tiwlan.ini” without any improvement. Question, should we not change the other 2 files (tiwlan_ap.ini & tiwlan_rfmd.ini), in this way?
Hi Pascal, some said they have to change the files “tiwlan_ap.ini” and “tiwlan.ini” to get the WiFi works, don’t know the reason, you can give it a try, and remember to restart the phone after change anything.
Hi Charles,
I’ve made this change (the 3. tiwlan files), no success…
I think, I’ill by a iphone 4s….
Bye
Well, if you have control over *your* wifi router, just change it to G mode only, and use TKIP instead of AES.
hi, i modified the tiwlan.ini and rebooted my phone, and it worked! thanks a lot!
BTW, there are two APs in my office, after this modify, i can only access one of them, i don’t know why.
By going in and turning that 1 to a 0, you are disabling the “N” type wifi. Some routers only put out type N, (not too many). That may be the case.
Worked for me, thanks!!
Change all the tiwlan files… still not working

I also have some wifi problems on the Defy, and CM7 didn’t fix it. It connects and works great, for about 10 min. If I stop using the phone for 5 to 10 min, let it time out and then turn the screen back on, it will still say it’s connected to the net, but it has logged me out of chat, and won’t load anything until I reset the wifi. Sounds like what you described, but mine does work, and then times out. Anyone know if this work around described here will fix my Defy? Will it work if I have CyanogenMod on it?
Edit to the above post: It worked!! NEVER disconnects now, EVER. Wish I did this months ago. Thank you for this info!!!!
i got tawlin.ini.bak is that all right orr…
“tiwlan.ini.bak” is a backup of file “tiwlan.ini”, you can use it to replace the file you have modified when something is wrong.
GREAT JOB MAN THIS HELPED MY MILESTONE 2 IM SO HAPPY NOW THAT MY WI-FI WORKS
it says error while saving… how to save the file? i really want to fix my wifi.. it is giving me headaches..
can you load up a photo to this page about that how looks like the modified “tiwlan.ini.”
thank you
My Defy+ couldent “see” my D-Link wifi, tried “everything” until I disabled “Wi-Fi Protected Setup” in the router and then I could connect.
