So here is how it all started. One day i woke up and my phone was continuously restarting and just got stuck on wifi turning on. This is a very common problem and is said to be a hardware issue. A common fix to this, is to open the device and put a couple pieces of paper on the wifi chip to press it against the motherboard. This fixes the problem for most. So this is what i did. But for me, now it identified all the networks in the area but when i connect to a network, it just says "saved"or sometimes "wifi connection failure". The restarting issue is completely gone. I have tried factory reset but no luck. I was unable to find people with similar issue so any help would be highly appreciated!!
I am using android 6.0
previously before adding the papers, the mac address also changed to 02:00:00:00:00:00 but now its back to normal.. but not connecting to wifi.. It just says "connecting" and then "saved".
Please anyone? I am still unable to solve this issue!! ::crying:
BUMP!
Same Issue
Did you find a fix? Im still facing the same issue.
I got the same issue but only with one router. I believe there is something with the router not G3 itself.

This problem arrises due to installing custom rom and restoring qcn and it could not be solved by restoring back to stock etc.
Simple solution to that problem is
First you need to install any Marshmallow firmware custom rom fulmics etc.
Then go to hidden menu
1- on dial pad : *#546368#*850# (850 is for D850 and write for your model )
2- find and click SCV Menu it should be 3rd one
3-click on CRCWIZARD Test
4-click the tab Auto MID
5- uncheck IMEI in MID settings
6- click generate to generate your new MAC's
7- click MID write
8-Click Refresh to be sure that you changed MAC adress
9-Rebbot phone to take effect!
After reboot you will be able to connect any wifi without having wifi saved problem or connection failure

Hey, I've got CM10 on my GS3. When I go under Settings, the Wifi toggle is set to Off and grayed out so I can't toggle it. When I go to Wifi, it just says "Turning on Wifi" indefinitely. I also have issues with wifi tethering sometimes.
Any solutions to this? I haven't been able to find any posts on it. I'd prefer not to reset to another ROM, but if there's no other ways to fix this, oh well.
Thanks!
Flash to a TW rom and see if it works.
If it doesnt work, try the following:

So as to fix this problem,some people suggest to do a Factory reset.But, it is completely unnecessary.Instead you can try the following methods, which where tested by me successfully.
1. Dial *#*#526#*#* to reload the wifi driver.If it doesn’t work, restart your phone and dial it once gain.It will work for sure.
2.There is an app “Wifi-Fixer” from android market,which claims to be fix this problem.But seriously,it hadn’t worked for my mobile phone(Samsung Galaxy Ace).But,
if you are interested, can download and try it here.
For HTC users, I have a pretty good trick which works very well.
When you have obtaining IP address problem,
1.Turn off wifi.
2.Open “Allshare”, then you will be asked to connect to a wifi network.
3.Then select the wifi network that you need to connect from the list opened.
Magically, you will be connected without any extra effort.This works 100% sure without fail.
If that doesnt work try this:
1.Dial *#*#526#*#*.Then a message will be shown “Driver loading Successful”.
2.Now Start the WiFi, it should work.
If the message “Driver Loading Unsuccessful” is shown, follow these steps:
1. Dial *#*#526#*#* again and click options button on your phone.
2. Select Rx test.
3. Select Channel >9 .
4. Click Start and exit.
5 . After some time, turn on the wifi.It should work.

My phone won't even let me dial that, the code disappears the second I hit star the last time, not sure if it's supposed to do that. I'm gonna just try updating CM and see if that fixes it.
I purchased my Galaxy Note II (GT-N7100 without LTE) in Hong Kong on November 18, 2012. Upon returning to the United States, I used the phone without any problems, until February 2, 2013, when I received notification on my phone from Samsung that an Official Samsung software update was available for my phone. I clicked the icon to select installation of the software update, which resulted in my phone being updated (over-the-air) from OS 4.1.1 to OS 4.1.2
After installing the update, my phone functions properly, except that I am unable to receive WIFI from my Netgear WNDR3700 Wireless Router, or from any other locations having free WIFI Access on the 2.4ghz band. When attempting to connect to WIFI, even when the signal is strong, the connection remains at "obtaining IP Address" for about one minute, and then displays "Network Disabled Poor Connection". Prior to installation of the 4.1.2 update, the phone connected to WIFI without problems. I did a Factory Data Reset, and it did not solve the problem. I reported this problem to Samsung in Hong Kong and the United States, and they were of no help.
I have concluded that I may be able to fix the problem if I replace the 4.1.2 wifi files with the 4.1.1 wifi files. I have since extracted the system.img file from the 4.1.1 Hong Kong ROM. I would like to unpack the system.img file to retrieve the WIFI folders/files, but have been unsuccessful in unpacking/extracting this image file. What software do I need and what specific procedures do I need to follow to unpack/extract the system.img file in order gain access to the wifi folders/files?

I am facing the same problem, can't get connected to any wifi.:crying: Did you fix the the problem?
Even I had this problem. You can solve the problem by switching off Power Saving Mode (PSM) for WiFi.
Tap Phone to start the dialer.
Dial *#0011#
The SeviceMode screen appears.
Press the Menu button and click WiFi.
You will see that WiFi Power Save Mode is ON. Click the ON button to turn PSM off.
Now your phone will connect to WiFi. But remember that every time you reboot the phone, the PSM is turned ON so you have to do it every time you reboot the phone.
GoodLuck

Keep calm and do the following:-
Download this zip file. And extract it to your etc/wifi folder.
http://db.tt/BWGleyxg
Since you need to overwrite a system folder, mount it as R/W from the default R/O using Root explorer or any other explorer(This is the important bit and there is no excuse for messing this part up)
Then copy and paste the conetnts of the "wifi" folder you earlier extracted to etc/wifi and choose "Overwrite files" option.
DONE.
If this doesn't work, then probably nothing will.
Doesn't work. I tried switching off the wifi powersave mode as you suggested and the first thing that happened was that I lost my wifi connection. That's with me sitting ten feet from my router.

I was having problems with Wifi connectivity ever since I received the 4.1.2 updates (around Christmas time). After trying the steps that I had suggested my problem was fixed. I am using the stock ROM. Are you on custom ROM??? You should try the steps suggested by zeeshanonlyme.
Wifi drop issue
I had the problem of my Note2 dropping its wifi connection as well. I tried the solutions discussed here - turning off wifi power saving mode, and copying the contents of the wifi folder from 4.1.1 to the /etc/wifi folder of 4.1.2. The latter worked for a day or two, then the problem started to reappear.
Last night I went into the advanced wifi settings of 4.1.2 and deselected "Network Notification" that informs the user that an open connection is in range. Guess what, my WiFi connection has been rock solid stable since then (crossing fingers ...).
Haven't stopped kicking myself yet. Try it, it might work for you.
This solution works? I'm almost tearing my hair out.

BTW you should post in Galaxy Note 2 Q&A forum ( use xda device search engine to locate it)
A modem change might give you results only after you have checked your APN ,
Quick Guide
First Check your settings > about phone > status > your phone number ( IF UNKNOWN )
You won't be able to send SMS by any third party sms apps or Have a Network connection
Solution :-
You need to edit that "unknown" number to your phone number, by putting your SIM card on any old phone that has a "my number/owner number" option, (most old phones do). Edit and save it to the proper phone format as your Sim Card number (Example: +63913XXXXXXX). Now put the SIM back to M110S, to solve this problem.
Than check your system settings, in Settings > Wireless & Networks > Mobile Networks > Access Point Names.(APN) as provided by your Network provider . If your Apn is not set, you wont be able to have data connection, so set it first
If still no data connection, Common Trick is to toggle WIFI and Airplane mode or
1. Turn ON WIFI
2. Set the phone to Flight Mode
3. Power down the phone for a few Minutes
4. Power it back up
5. Turn OFF flight mode
6. Turn OFF WIFI
Should get Data back

Hello,
My phone can not find any network. Phone recognizes the SIM, when i try to select manual 4g/3g/2g phone does not find any signal. Wifi and bluetooth working.
When i look in "phone information" Mobile radio power is off and preferred network type is wrong. I cant get it on and i cant select the true network type.
I did flash modem.img again and again.. I don't get what is the problem.
Before that, i broke the partitions as 45/46/47 and /vendor, after i recover these, Phone works fine but i face the this dead end problem..
I tried these;
Flashing AOSP, same.
Flashing (same model RN5) modem.img
I did flash the global rom a few times
Reset tens of times..
How can i solve this problem ? can anyone help please ?

Modem always crashes especially when outside. As long as I am at home on wifi, it seems to work, it crashes but not a lot (sometimes even during the night). But going outside and the phone switching to cell/wifi/cell/wifi/etc make it crashes rapidly.
Easy to see because I am losing voice/data. Phone does not reboot.
My F3 is stock, stock rom, never been unlocked or anything. It did this last year already. I am using the latest MIUI 14.0.4.0(TKHMIXM). I'm in Canada with PublicMobile.
error is
modem subsystem failure reason: ssr:MP:rflte_dm_rx.c:8779:rflte_dm_rxagc_config_update_switchpoints_and_lna_offsets_in_d
I have a lot of ramdump, for instance right now I have

Would disabling specific bands fix this? Is so, what ones?
In another thread it seems someone tried it and it changes nothing :-/
Dial *#*#663368378#*#* to access modem test tools suite, hopefully something there can tell you more about what is going wrong
It seems I cannot access "MODEM test tools" (aka Rueban / MTB) app on official ROMs without authorized Mi Account according to some search. It only gives me a black screen.
Well that's mildly frustrating. Sometimes theres modem debug options in city (dial *#*#6484#*#*) tucked away in the 3 dot overflow menu in the top right...
Unfortunately there's no such option here :-(
I have a lot of ramdump about modem crash, always the same error. I tried to email poco support but gmail reports back that the server refused connection or something...
