A few days ago, the wifi connection to my Verizon Note II stopped working. I see a strong signal from my router, and it attempts to connect, but inevitably gets "Authentication Error". It did the same thing with other networks, so it's not just my home wireless.
This is a well-known problem with 4.1.2 - and has been for a while. Google it. I did, and quickly went down a rabbit hole, leaving me frustrated, confused and still no closer to a fix. So I installed a 4.3 ROM, which also required an updated firmware.
I was using Jelly Beans 22 (http://forum.xda-developers.com/showthread.php?t=2032447)
I wiped everything and installed JellyWiz 4.3 (http://forum.xda-developers.com/showthread.php?t=2564495) with TWRP and VRUEMJ9 WIfI Firmware via Odin.
And still the error persists.
F** it. I'll jump to KitKat.
So I wiped everything again, updated TWRP, and installed Gummy (http://forum.xda-developers.com/showthread.php?t=2592339)
STILL NO WORKING WIFI. Same "Authentication" error
In between the above steps, I have tried literally everything I could find to fix this problem. Restarting my router (duh), changing settings in the wifi menu, the hidden "service mode" menu, energy saving, even dropping the /etc/wifi directory and replacing with a copy from 4.1.1.
What silly, stupid, inane detail did I miss?
SCH-I605
Android Version 4.4.2
Baseband I605VRUEMJ9
Kernel 3.0.64-gummy...
Have you updated to the mj9 firmware?
Fine. I'm done dealing with this, I thought, and nuked the phone back to the stone age.
Using Odin and instructions here: http://forum.xda-developers.com/showthread.php?t=2024207 I flashed back to 4.1.1 and a full factory reset.
Still. No. F***g. Wifi.
I have now spent the entire weekend upgrading and downgrading my Note II, to no effect. I'm almost *almost* convinced it's a hardware problem. If it didn't match so many other examples of a 4.1.2 wifi bug, to a T.
Anyhow, to the Verizon store I shall venture on the morrow, and demand satisfaction.

Yep. As part of flashing to 4.3 and Jelly Wiz.
No dice.
Did you use Odin or the flashable zip? ONLY the Odin method works. I tried using the zip, and while my phone said it was on mj9, it didn't update anything but the modem. This left me unable to use my WiFi on anything over 4.1. I hope this can be of some help

Hi Team,
I have a GT-19100T which had the carriers firmware (Vodafail AU) 4.1.3 (rooted) running with no problems until recently (2 wks ago), prior to the fault I have had this phone for years no glitches great phone for its age.
I had let the battery drain, upon re-energizing the phone and attempting to turn on the wireless i noticed it just reported "Turning WI-FI on" and the toggle switch was greyed out. this would last all day. switching the phone off and on would not stop the process of the phone attempting to turn wi-fi on.
I immediately went searching forums and people suggested hardware fault or perform factory wipe through CWM.
Troubleshooting I have performed so far is:
- factory wipe and cache cleanup (not resolved)
- flashed to CM 10.1.3 (not resolved) (multiple times)
++++
OS: 4.2.2
Baseband: 1900TDULP4
kernal version: 3.0.64-cm-g9c2e2bc
++++
I have found from research that the Bluetooth and wi-fi are the same module (I maybe wrong) and Bluetooth is working fine.
So this leads me to suspect a software/firmware fault.
I'm currently downloading I9100TDVLSM_I9100TVAULSF_VAU.zip from (sam mobile) the latest release for this phone from the carrier to see if firmware will resolve the problem.
In the mean time any suggestion, advice, help or solutions would be greatly appreciated.
Maybe if someone knows of a file i can flash specifically for wi-fi module that I could try.
Thanks in advance

I have same problem few weeks ago when my galaxy on Stock Rom 4.1.2.
Later, I try to reflash again through Odin, then install CWM and I flash CM 10.2 4.3 through CWM and it solved.
I think you should try to flash Newer Rom version, example CM10.2 or SlimKat.
Good luck

Thanks mate for your reply,
I installed cm 11, this did not resolve it.
need the file for the radio/modem, i'm hoping this will fix it but not sure exactly what I am looking for.
**Update***
Just finished installing I9100TDVLSM_I9100TVAULSF_VAU (latest release from Sam Mobile) 4.1.2
Still wi-fi not working.
will try and install cm 10.2 on your recommendation huytrandinh
Okay latest nightly of CM is installed cm-10.2-20131216-NIGHTLY-i9100.
Still has not resolved the wi-fi issue.

Try to flash a modem using odin,

Modem won't solve the issue as WiFi/BT drivers are in the kernel on the S2. OP was on the right track, but for whatever reason a clean install of stock didn't fix the problem.
Maybe try the 3 part firmware in Hopper8's Odin Troubleshooting thread, then a clean install of the Voda stock rom after that ?
There's 'WiFi fixes' (which are actually the LTE modem) for the I9505 as it actually has two separate modems, and the LTE modem also controls WiFi (which isn't the case with the S2 as per my comment above).

Thanks Mistahbungle,
I checked out that thread http://forum.xda-developers.com/showthread.php?t=2345831
Nothing i could really use.
But I did try a few other kernels:
Siyah-s2-v5.0.1
Unfortunately as soon as flashing with other kernels the screen would go black after the initial boot logo.
Only way to resolve it not booting into the OS was to roll back to:
1. GT-I9100_JB_ClockworkMod-Recovery_6.0.2.9 (flashed with odin)
2. flash CWM-SuperSU-v0.97 with CWMRecovery
3. install cm-10.2-20131216-NIGHTLY-i9100
4. then your general cleaup through cwmrecovery
I'm not sure if I'm doing something wrong when trying to apply another kernel.
anyone able to offer assistance please with right kernel?

Will try the 3 part rom XXLSJ for GT-I9100.
Fingers crossed
Yeah, that's what I suggested in my PP. Sorry, seems the 3 part was on HotFile & Hopper didn't have his own copy up somewhere.
The rationale was - there's possibly something from a previous installation causing your issues, and flashing the 3 part would wipe your phone. I realise you've done this manually, but at this stage you're fast running out of ideas before you declare it a possible hardware issue, and it was worth a shot.
So...What I'd try is - while you have a rooted phone, go into CWRecovery and format everything/ (not EFS though obviously, or your external card if you have one), then try re-flashing whatever stock firmware you have with Odin in download mode.
Edit - Also, maybe do a Google search for that 3 part firmware (details are still on Samfirmware, just that the files are gone), you never know, you might find it somewhere.

Okay just finished testing the rom by installing it via odin (3 part)
still has not yielded any favorable results .
Little disapointed as this was a great backup phone and served for the past 12 months as a mp3 player
Guess as they say; It is all planned obsolescent which is fracked ...
Thanks for the suggestion/help anyway.
I know this is an old thread but my gs2 had this problem and I was able to fix it. Using es file explorer made my way to /data/misc/wifi pulled up the properties to wpa_supplicant.conf and changed group to wifi...then wifi finished initializing...hope this helps somebody

for consideration.
I have this phone. the GT-i9100. Had this issue also. I took it apart. The little onboard battery had blown and corrosion got all over all it.
and guess where WiFi hard is. Right Next door. I cleaned it up real good. Put it back together and WiFi came back to life.
So give it some thought guys.
Alright guys, this is gonna be kinda long so get ready. I was running stock 4.4.2 NEW and I saw that there was a way to get GPE 4.4.3 and 4.4.4 rom working on the s4. I followed all the instructions on RickGrimes's post and wifi didn't work. Not and big deal. I couldn't soft reboot, so I tried flashing gogolies nc2 wifi fix and this modem worked. I then tried to update to 4.4.4, also following the instructions and the wifi didn't work once again. I flashed gogolies nc2 wifi fix again but it did not work. I also realized that I had no service at all and that I couldn't send or receive any messages or calls. So I did the safe thing and used Odin to get back to stock. I am currently running stock but the service is still terrible in places where I usually get great signal. Also, my wifi strength seemed to go down from what it usually is. Another issue is that my contacts that were backed up in backup assistant aren't there anymore at all. I generally know what I'm doing when it comes to this stuff but for some reason I have no idea how to resolve these issues. Any help will be appreciated.

The easiest way to fix your phone or any phone for this matter is always to download and flash the stock tar file of whatever version of Android you were last on in Odin.

I wound up going back to stock 4.4.2 via Odin, but the problem still persisted. I figured out the my network settings were changed to Global instead of CDMa/LTE. Changed it back and all is well! Thank you though!
Device: Galaxy S3
ROM: Slimkat
ROM version: Slim-4.4.4.build.6-OFFICIAL-5242
Build: slim_d2lte-userdebug 4.4.4 KTU84P 5242 test-keys
Kernel: 3.4.95-cyanogenmod-gd56ed95
I purchased my S3 in April of last year (4.1 Jellybean), and at the time the wifi worked perfectly. After the first (or second?) OTA that was pushed to my device, my wifi started acting up. It would cut out and I would have to cycle the wifi off and back on in hopes it would work again. I have been patient hoping they would push an OTA that would finally fix it. A year or so and a few OTA (I don't recall how many, or which versions) later and it still doesn't work properly, so I decided to finally try a custom rom to see if it would solve the issue. The last stock version of android I was using was the 4.4.2 OTA.
I rooted my device using towelroot, flashed CWM Recovery (CWM_6.0.4.7_Non-Touch_GT-I9300) using ODIN 3.04, then proceeded to flash the Slimkat rom listed above using CWM recovery. The wifi seems to be better, but it still cuts out and is unresponsive even though it says I have full wifi signal. A wifi cycle seems to fix it temporarily, but I'd like to solve this issue.
So as far as I can tell the last working modem I had was stock 4.1 or so. So I guess my question is, can I flash previous modems to try to get a working one with this rom? I have tried using WIFI Fixer from play store, and even with full signal on WIFI I get signal poor, signal hop scan messages spammed. Any and all help would be greatly appreciated!
So ive run out of ideas on this problem. I no longer can update my prl and profile. I was on freeza's not3 2.2/2.25b rom had some issues with slow data and other hiccups. Flashed stock debloated and got tired of its blandness so i moved back to freeza's hoping for a better experience now that it had some time. After flashing back to it ive run into these issues.
Poor network signal, unable to update prl or profile with error code 6602. Ive gone stock tar nh7 and reflashed the modem too with no solution. Ive regained network connection after losing it entirely for a bit but still cant update prl or profile. Everybody else is talking how theirs is working great....i havent done anything different. Hope to get some input. Thx ahead of time.
Reminder at this point everything is stock flashed on odin. Twrp recovery latest version. Odin 3.09

I had similar PRL/Profile problems, 'tho I was getting error code 6500. Network connections remained strong and through-speeds were very good. But the failure to update Prl/Profile really pissed me off. I also tried return to stock, other ROMs, but same error 6500. I just lived with it and did the occasional battery pull to good effect.
Then I installed Sacs_Note4 _Ported_apps_Rom_V2.
As part of the installation instructions, I updated PRL & Profile and was shocked when they worked!
Then I set up the phone as I like it, and back to error code 6500.
I turned-off the various Wanam mods and presto, no 6500 error code.
I then added them one at a time, (stuck with a few less this time) and still no error code 6500.
Good luck!
For anybody that wants to go back to 4.4.4 from 5.0 I can confirm it works great, I just flashed back with Odin. The 4.4.4 firmware is at sammobile right below the lollipop firmware. The 4.4.4 flash put it into a bootloop to which I then factory reset and it started up perfectly with none of the completely unusable issues I was having.
Bummed out that I can't use lollipop for the time being, but more than relieved that I have a usable phone again, I thought it was toast.Lollipop made my phone worthless, literally couldn't do anything, major bootloops and constant crashes.
I made another thread about it here
http://forum.xda-developers.com/verizon-galaxy-note-3/help/reboots-lollipop-t3090421
You should retry the upgrade, it's faster and more stable. You just had a corrupted file or something, if you really want the best is worth a try. It's 40% faster. There was just something wrong with your install.
Did you do a factory reset when you upgraded? A lot of Note 4 users who upgraded had similar issues which a factory reset corrected.
I took the upgrade and found it to be faster and more reliable as well. Still fingers crossed for a root exploit. At least we know if an exploit ever happens for 4.4.4 then we can downgrade to get it. Good to know!
Oh really? I thought we couldn't roll back after taking 5.0. I am having a hard time a stable host to download 4.4.4
Can someone help me out with this? <confused>

Success! The 4.4.4 firmware took forever to download but worth it! Thank for this!

Trust me I really wanted it and tried all the usual steps. I think something is wrong with my phones hardware that works mostly ok on this version. I actually stayed on an old version for a very long time, I rooted "root de la vega" and took one ota using the supersu option to keep root when using an ota. The next update after that would not work for me, I would have had to wipe and odin to update, so I held off thinking I wasn't missing anything. Till about a week or less after 4.4.4 came out then my phone started crashing the moment I received or made a call. I hadn't gotten any new apps or anything like that but just in case I factory reset to see if it fixed with no luck. So I finally upgraded via odin, no root now, but miraculously my phone could make calls again. I am giving you this essay because I have a feeling this issue is related. It seems it's my phones hardware that is messed up and i'm just lucky that 4.4.4 works at all. I still have issues every couple days where I make or receive a call and hear nothing, with a reboot needed to fix, that is confirmed still after a fresh install of 4.4.4 after all the 5.0 stuff I tried. Anyways thats why I think it's my phone. I wish I had an extended warranty so I could just update and make a claim.
As for everything I tried in the update, I took the ota, which was literally unusable by anybodys standard, I could use the phone for about 5-20ish seconds before it would crash, turning the sound to mute would help, but still crash at a couple minutes of use. I downloaded the firmware and flashed via Odin, same exact issues, changed nothing. Did several factory resets between all these steps. I kind of walked through the process on that thread I posted in the OP.
After making this thread I did try it one last time and flashed via odin, knowing that I had a workable fix, but same exact thing again. If they release another update I'll try then, but looks like I'm stuck till then at least.

Can you be more specific? There are two firmware versions that are 4.4.4-NJ6 and NK1. I assume you used NK1? I'm a newb and sort of know how to use Odin/download mode. What version of Odin did you use?
I want to rollback to the previous build until they sort out the radio issues. My phone was fine on NK1 but on lollipop it drops LTE indoors frequently. Aside from the radio issue, lollipop runs great. I factory reset after the update, didn't make a difference.

Okay, to anyone whose interested: I used Odin 3.09 & NK1 (most current VZW build of 4.4.4) and it worked. Phone went into a bootloop, started recovery did a factory reset an it's back to normal.
Lollipop ran fine on my phone-probably because I reset it as soon as I updated...BUT, my data signal was halved. I get a weak LTE signal at work and by weak I mean 1 or 2 bars 105-115DB at best. Old brick building and I work in the basement. On lollipop, it wouldn't hold onto LTE anymore. It'd flip between 1x/3g..usually settling on 3G. Voice was unaffected. Hopefully they sort this out but this sort of signal performance (especially when it was fine on KK) is unacceptable.
Rolling back to NK1 has solved that. Thanks to the OP!
I can also confirm that flashing 4.4.4 NK1 from 5.0.0 OB6 works.
Tried it myself, but after I got done playing with it I went back to 5.0.0 OB6 afterwards.
I didn't look to see if it kept the 5.0.0 radio when downgrading to 4.4.4, but it kept the 5.0.0 boot loader.
I did not test the radio (as I didn't have a usable sim card at the time.)
Also, don't try to run URDLV on the 4.4.4 firmware before flashing, it will not boot (even with a factory reset.)
But I didn't try to flash a modified 4.4.4 firmware after 4.4.4 was already on there.
so just so I understand there's no root for 4.4.4 or 5.0 but it's possible to go back to 4.4.4 from 5.0 ?
