It finds the WiFi on one firmware but not that other?
could just be one is slightly buggy, Or there is a very small possibility that there could lay a hardware problem (more than likely not though) - try and keep on the MJ7 fw if you can, as for rooting and having the issue. It certainly seems strange. - Assume you have tripped your KNOX ? Try stock flash via ODIN and then try and see if you can root it again, if you haven't tripped KNOX already then it will trip it so be careful.

OK, if you have upgraded already (which you have) to MJ7 you won't be able to downgrade back to MJ1, MJ7 carries a new bootloader and Samsung have blocked downgrades. - Go on to sammobile.com and find the stock firmware you need with the CSC you require. - Flash the stock firmware you need to the device with ODIN, then once you have done that check your WiFi to see if it works or not, then root the phone as you normally would and see if it still works. It seems like it's just a small bug with the software.

XSP -CSC and N9005XXUDMJ7 is the stock firmware you require on your device? -- I'm not sure what the issue could be, as it is only happening sometimes and not all the time, so that rules out HW and a list of other things. I'd put it down to buggy software. Go with the firmware that worked, that is the safest option currently until you/we can figure out what the issue is.

if you're rooted, maybe you can try this, mine n900 works fine

Do not mess around with PIT files and re-partitioning unless you know exactly what you are doing and what each file will do.. cause you will end up with a nice paperweight.
Factory reset, wipe cache and boot into stock and see what happens.

hi, thank's for all your answer. This Note 3 will make me crazy. At this time, i decide to try to rooted and add Wifix manager, and try to change wifi region, when i do that, for moments recognize my wifi, but at the moment don't recognize, which region code i have to use in USA ?? or help to find a solution thank's

Another HONG KONG ( TGY ) Note 3 SM-N9005 with WIFI PROBLEM

Hi all,
I just bought a note 3 on ebay with a fault "wifi can't connect to networks" .
I received it 2 days ago and turned on then turned WIFI on, connected to my network and everything was fine.
After a minute it shows software update available so i let it do that. Downloaded 81MB trough my wifi network then it had the update.
After the update finished I can' turn the WIFI on anymore.
Then I just take the battery out for few minutes, install it back, turn it on and it fine again. Until reboot..... Then battery out, wait, back and fine...
Kies update to the latest firmware-nothing changed...
After a quiet few hrs of reading forums i made a decision to try flash a UK official rom from sammobile. Odin failed. Then i installed custom CWM and tried install OMEGA ROM V6 . It was looking all good until reboot. Stock on the note 3 logo....
I di give a go anther UK firmware but no luck.
No im back to HONG KONG TGY again and the phone but fi.
Simle i just can't turn it on.... It shows turning on theen after 2-5 minutes it just off.
If i reboot the device WIFI always try to turn it self on, without pressing it..... This was a same when it worked. I tried to reboot the phone without removing the batte and WIFI OFF but it was rebooting and WIFI was "turning on" but wont work...
So th Q. is: Where can I go from TGY or can I change modem or CSC or something to give a go?
Right now it official TGY:
Android: 4.3
Baseband: N9005ZHUMDJ9
Kernel: 3.4.0-2061029

Anyone got any tip how can i fix this?
Thanks a lot!

Reflash the custom ROM and update your baseband to MJ7.
Though, a word of warning. As far as I understand, you can't go back to a lower baseband once you do this.

Still TGY after costume rom and baseband changed....

I had a go a few hrs ago and i managed to change the rom to omega rom.
Kies was showing:
:
PDA: ML2 PHONE: MJ9 CSC MK3 (TGY)
How can CSC still TGY???
After this I downloaded a new GSM modem ( N9005XUDML2 ) trough omega rom and installed succesefully.
Now KIES shows
PDA: ML2 PHONE: MJ7 CSC MK3 (TGY)
I did belive after install the N9005XUDML2 the baseband should be ML2....
Wifi still not working and still shows "turning on" then after a few minits it just looks like it off.
After I reboot it it is "turn on" again..... (without me turning on)
So again how is still on CSC:: MK3 (TGY) as TGY is the Hong Kong provider but everything is different now.....
Also why wifi is always on automatically in boot up?
Thanks for ANY help!

Try flashing the pre rooted MJ7 ROM (Odin) from here: http://forum.xda-developers.com/showthread.php?t=2461929
If it goes like how it went on my TGY Note 3, the flashing will give an error when it tries to flash system, but before that, it should update your baseband to MJ7. Custom ROMs should work fine after that.

Wifi fine again temperately?
Here is some update:
I removed the battery last night and left a phone like that. This morning i had start the phone and the WIFI was OFF and i was able to turn it on. Now basically works how it should as i can turn it on / off as many times i wanted to. Im sore if I reboot the phone without battery removed it will have the same problem again... I will try this tonight as i will set the phone up for my self during the day..... If WIFI goes wrong after reboot again i will leave the battery out for a night again.....
The Q. are the same. Why WIFI is "try to be on" after normal reboot? ( battery in phone ) ? After custom rom installed why it is still sows CSC is TGY?
Thanks !
Sammy

I'm at a loss, man.
Tried any of the CSC changing app?
And in my previous post, I was trying to get your baseband updated. That solved a lot of issues for me.

Wifi well get stuck or well refuse to turn on if you have the wrong radio installed. You'll need a firmware and baseband that works with each other for wifi/data/cellular to work. I would reflash the Baseband

hey thanks a lot for the answer, did you midn to teach me in tutorial please

Flash a fresh firmware using ODIN or Flash a rom of your choice in recovery. It should update your baseband. Make sure its region free or made for your region. I myself have never flashed it on my Note 3. But wifi being stuck has happened to me on countless different phones and it all points the the baseband/radio installed.

Signal problems

Hi
I've had the i9505 for more than a year now, within the week of buying it I installed wanamlite rom with no problems, maybe a little weak on the signal, but nothing major, but a couple of days ago y wanted to try the latest one from wanamlite, but after installing it the signal was horrible, no signal for the most part, I read it could be the modem or something, so I changed the rom to goldeneye, now I have signal but no internet (I have 3g), does someone know what could be the problem and how to solve it?
I have a GT-I9505 4.4.2
baseband I9505VJUAMDE

well all that depends in what bootloader you have , if you were 4.4.2 before you installed wanamlite you could flash any of the newer ones or
update all modem / bootloader as your knox has been tripped already

re-flash 5.0.1 again
somehow your modem is still old one (wasn't updated)
I had similar situation with "unable to turn wifi on" when updating OB7 -> OE3 (both 5.0.1, just new build).
It took me like 4 flashes before my phone finally grabbed modem files enabling wifi again.
Tried different Odin versions each time, forgot which one finally did it (possibly the one shipped with CF-auto-root)

Hardware failure. It's not software. If it was software then it just would not work at all.
Service center or let someone replace the wifi module.

Thank for suggestion, i will try go Service Center. or maybe i will change phone.

Also I did another option for change modem.
http://forum.xda-developers.com/showthread.php?t=2192025
I did it.
But, the baseband version, didn't change.
MODEM: I9505XXUEMJ5 to MODEM: I9505XXUEMJ7.
ODIN = PASS
Now appear I9505XXUEMJ5.
Well....

I'm having a similar issue
It started when I went Form Cyanogenmod 11 back to Stock 4.4.4
Every new method i came across would get it working for a short period of time then i would quit working again. I think ive exhausted the method of trouble shooting.
Method of trouble shooting thus far: safe mode boot, changing Wifi and bluetooth supplicants which worked for a period then deleted and booted in to safe mode which worked until reboot. Ive also tried numerous rom flashes both stock and custom along with modem flashes, short code and build.prop modification all to no avail
So this is what i believe I know. If I'm wrong if someone could kindly lead me in a direction of proof. I DO NOT believe it to be a hardware malfunction. For several reasons: 1. if it were a hardware issue would it simple not work at all 2. When using a stock rom every time i go to turn on wifi it tell me that some security measure is kicking in and no further action is required, but only for a brief second in using the back key to exit the message does it give my a list of networks around.
Which leads me to believe that its KNOX or KNOX related
I'm currently working with a Knox 0x1 9505
Is there any way to modify/add security credentials to by what ever might be the issue
