Why did this happen?
How to handle it?
cm7 # 20 - # 34 are like this, WIFI connection is not on,The official 2.2 or 2.3 can connect wifi.mac address is correct,Several friends also encounter this problem, hope to solve technical friends about.
I come from China, the English level is not high, I hope you understand.

Might this be due to ur not using optimus black, but marquee? Maybe u need a special version of the software, i guess any1 can customize it ;-) u can also try wifi manager to fix it

U pushed thank button, so it worked?

no, I do not know how to work, but very grateful for his reply!

Did u already try WifiManager from android market?

Today has been tried, and the WIFI method is useless, or the last mac address 00:00:00:00:00

who can help me?

[Q] Wi-Fi and Bluetooth not responding

Hey guys. First of all I want to thank you all for detailed information and in advance for helping me I've got a really weird problem that I can't solve. I bought my milestone from a guy(second hand) and I found wi-fi and bluetooth is not working. I thought that I can solve the problem but I can't find any solution over all android forums.
I flashed some different ROM's but nothing affected the Wi-Fi and Bluetooth problem. When I try to Turn On Wi-Fi it tries to start and then stops then again starts, it goes on and on. I tried to find original MAC address it shows 00:00:00:00:00:00. I tried to Mac Spoof but I can't change it from terminal.
And for the bluetooth I click Turn On then it tries to turn on and stops like I didn't click anything.
As a summary I lost my Wi-Fi and Bluetooth. Anyone can help me restoring it back to normal? Cause in my Area 3G is unstable and I want to use my home network! I can't use it any more. I'm waiting for the good responses.
Thanks in advance...
Please help. This is important for me... If someone helps me I'll donate 15 USD from paypal. Thankssss...
There are several possible reasons why it's not working. They include:
Bad hardware.
Corrupt software.
Non Stock Firmware.
To eliminate the last two, you can flash the appropriate SBF.
To do this, follow the instructions on how to get your milestone back to stock here: http://forum.xda-developers.com/showthread.php?t=696845
On the page to get sbf, scroll down to the 2.1 section and dowload the latest version for your carrier
This will completely wipe your phone, and make it like a new phone. If that doesn't resolve the issue, the problem is probably hardware related.
If this worked for you, please donate the $15 to xda. You can do that via http://forum.xda-developers.com/donations.php
Thanks for quick-reply. But i tried this one before. But it didn't solve this issue. I'll try one more time... How could hardware (both bluetooth and Wi-Fi) be bad? There must be a way to return it back... I'll update this as i try again the original file...

I'd assume that the same chip runs both as is usually the case for embedded systems. If the original firmware doesn't work, the it's likely a hardware issue.
I tried a new update and bluetooth worked for once. And then stopped again. And I sent to warranty they said they cannot change all mainboard cause it'll cost near phone's cost. And after I see Bluetooth works for once I thought may be it's radio based problem. How can I update the original radio update only? Thanks in advance...
I have got exactly the same problem.
I have already sent it back to motorola under warranty and they changed a few things. It work for about a day and then exactly the same.
I thought the update to froyo would work, it did for a day and then reverts back to the same problem.
Have you solved this yet?

try to assign staitc ip............it happened in i9003 too
download a root explorer, go to data/misc/wifi/wpa_supplicant.conf and set: update_config to 0 and priority to 1, it doesn't solve the problem but it gets a little better

i guess he means 528 instead of 526. *#*#528#*#* is the wifi test mode which loads the wifi drivers automatically.

Yeah there are plenty of those codes actually.
for example:
*#*#7780#*#* factory reset
*2767*3855# factory format (everything wiped, also the internal sd card)
*#*#1575#*#* gps test
*#*#1234#*#* pda phone version
*#*#1111#*#* fta sw version
*#0*# lcd test (cool one )
*#*#2664#*#* touchscreen test
they should work on every android device. try google to find more
Thanks mate
So after the tips from Sakindia and BackDaws, when i changed the phones ip to static, and changed the routers DHCP settings, i have no more problem with the wifi connection.
Thanks again guys
I hope, that this thread will be helpfull fo other S+ users

Change title to "SOLVED"
If it is set to static ip and you changed dhcp settings it is only solution for your home network, not anywhere in public, right?

This was exactly the cure for the problem, I can also confirm it. I tried several things, such as exchanging config files between several ROMs, what a waste of time
But I'm still wondering why 2.3.4-2.3.6 can not work with forever leasing time... It's bad.
p.s.: for me no static IP needed for proper work
Thanks for sharing this BackDaws!

XXKQ7 WiFi Problems

Ok since nobody will notice this problem on i9001 general topic on i9000 category, i will make a new thread here.
How do fix this problem ? after a long sleep, like 1-2 hours, wifi will automatically drop and 3g won't properly connect.
Also, Google Plus app can't be deodexed or installed either, so it gives crashes.
How do we fix these ?
Here use the xxkp4 modem http://dl.dropbox.com/u/63588663/SMD_MODEM_I9001XXKP4_CL374422_REV00_user_low_ship_EMMC.rar
Somebody with kq7 please try them and tell us if it's working.
But couldn't we have the modem from xxkq1 ? i am on kq1, just tell me what files to extract and i will make an archive.
I need these files in the "normal" version too (not at .smb format). Can anyone help?
i don't seem to be having the wifi issue... is there any other way i can test to see if i get the issue just to see if there is an isolated reason for the wifi drop...
Edit: just so you know it is XXKQ7 and i did factory data reset from privacy menu in settings after initial boot... and i haven't changed any wifi settings, it's not rooted either (kept it unrooted to test this wifi issue)...
check this thread guys maybe will help you a bit abt wifi probs ...
Nah, it didn't help me.
Tbh, i'll wait for Samsung official Value Pack ROM for us, since KQ1, KQ6 and KQ7 are beta.

[FIXED] Android and TP Link TL-WR941N Problem

This problem only exists with Android phone not Windows computers, Nokia Express music phone...
I can't download huge files more or less 10MB because the internet virtually disconnects even the wifi connection is still okay on this TL-WR941N and also happens on some android devices like Xperia Ray.
On MOST routers, my Xperia X8 (MiniCM7 2.1.1, nAa-13), it has a decent connection with less failure of cutting my downloads than our router.
So I'm suspecting the 'AUTO' settings of this TL-WR941N which could be the reason why my phone disconnects when I'm downloading using BROWSERS (Downloading) and OSU!DROID (Downloadind beatmaps) while in GOOGLE PLAY, it doesn't...
If you do KNOW why, please RECOMMEND me the best settings and also I want to keep the BGN mixed because my Xperia X8 and other X8 (Stock ROM) does connects with N standard but speed like B standard... even with the N standard mod... useless mod...
In short, it IS connected to Wifi but there IS NO internet connection after it cuts my download (It only happens on our router)...
I need some advise...
PS: Happens on MiniCM7, MiniCM9, PrimeHD. On stock ROM, it has good connection though... I don't personally like GDX due to personal problem of the ROM, sorry about that... I don't want to return to 2.1...
I have the same router as you, and I never had this problem. You have the latest firmware on the router?

Pppoe is my internet connection.Take a look. Do update the firmware. If you compare the first image, you'll see the firmware is very old at you.

Thank you very much! I didn't know the firmware was outdated... Actually, I tried to see if it's updated, but still don't know about routers...
Somehow, it can now download smoothly... Some apps with the same problem is also fixed... Problem is now FIXED.
I appreciate your hard work for helping me out.
PS: This is my first fixed problem on XDA Q&A

[Q] Wifi connection unstable after update to 2.3.1

Hey there!
I recently rooted my I900 (which I had never updated before) using SuperOneClick and everything worked just fine. Now I decided to update the firmware to 2.3.1 using Kies and it worked(my root is gone, but I knew that), but now I have run into a problem: I lose my wifi connection every 40-60 seconds or so, which makes online games or downloads impossible. The Wifi symbol dissappears for a few seconds and then returns, the internet works again instantly, but, as I said, any download or the like is cancelled. I tried getting a static IP adress and turning WLAN standby mode off, but to no avail. What seems to be the problem? What can I do? I would like to fix that without formatting anything, if that is possible.
Thank you very much in advance,
WittyWhiteFox

why not update it to 2.3.6 First, normally KIES will update to the latest for your region, so check here for your region or use webversion of Check Fus 2.0 ROM Downloader
Thanks for your answer.
In fact, I already have updated to 2.3.6(instead of 2.3.1), I made a stupid mistake there, sorry ' bout that.
But I managed to fix it, turns out my static IP configurations where somewhat off. I used a guide I found (but can't post here because I'm new) and now everything works just fine. So, yeah, my problem's solved, sorry for wasting your time. ^^
