Wifi Connection Losing Password - Galaxy S 4 Q&A, Help & Troubleshooting

I did some looking around but it's really hard to tell whether someone is having the same issue as me, so I thought I would post here and ask you guys for a bit of help. Yesterday I flashed CF-Autoroot and rooted my phone (GT-I9505). I also flashed KT Kernel and used the suggested values to start with, but haven't gotten adventurous. I'm running stock TW 4.3.
Anyway, moving on to my issue...I'm having a wifi issue where - it will connect fine once i've typed in the password, but when I leave and it disconnects from my router, or if I turn off my wifi and then back on, it forgets the password and I have to retype it in to reconnect. Is this an issue with the kernel? Or because I rooted? If it helps with the answer I'm on DBT (Deutsche Telekom - Germany) software. Thanks in advance for any assistance that you can give.

[Q] - i9507: No service on KitKat - Can receive calls, can't dial (no service)

Hi Guys,
I'm from Australia and recently bought an Optus Galaxy S4 4G. Strangely, the model number is i9507. I double-checked this online and usually weird model numbers are just carrier-spin-offs. So I went ahead to root and flash just like you would with an International i9505.
So far no problems - 4.3.x PA rom works absolutely fine.
BUT:
I've tried some Kit Kat roms recently and they all flash fine but give me 'mobile network not available'. Strangely though, I can receive calls/text and talk on the phone, but when I try to dial or send text messages, I can't do it. My reception bar is completely empty as well.
WiFi is totally fine, just no data and mobile network
I've tried messing with the 'network operators' setting and if i select my carrier (I have a Vodafone sim) I'll get network reception until I turn off the screen and then my mobile network becomes unavailable again
Not sure what the problem is; modem? APN? or roms not suitable for my phone?

I've been flashing for a while now but it's usually just basic stuff so you can probably tell I'm pretty amateur lol.
Any help is greatly appreciated!
Thanks =)

Hi Rich
As your baseband is quite out of sync with the firmware you are trying to run (MH2 is from 4.2.2 ,,, right?) I would suggest you change your baseband (modem) flashing an equivalent to the ROM firmware from here.
I've got yesterday the exactly same behaviour when finally and reluctantly I've added a data plan. I was running a successful low-baseband + high-firmware because was setted to "GSM Only" (try it ... will work flawless). When I've switched to LTE got what you've described in the face too . I've promptly updated my baseband and now all is fine :angel:
EDIT: please do nothing of the above described BEFORE taking a EFS backup with every tool you can find and preserving them in several highly fortified locations and 2 or 3 K7 Tapes too . Have an ODIN flashable copy of your MH2 baseband is advisable too.
Hope I've helped and please share your experience.
Nice regards.

Hey thanks for the reply! Helps heaps =)
While I still had those roms installed I did try flash a few modems within Odin, all failed though =S
Which one should I be flashing?
I believe I tried XXUFNA1 but the flash just doesn't go through
Does it make a difference which rom I flash the new modem from? I.e. flash when the new modem now or flash the new modem on the kitkat rom?
I'm currently using Pacman 4.3.1 since it's perfectly fine. Just can't wait to get on a KitKat rom though! haha

Hi Rich
Sorry, may be my fault, but quite didn't got your
You may proceed having the below as a rule of thumb:
Your baseband (modem) version should always match your ROM (firmware) version.
Failure to flash something is never good signal. As you have an i9507 (I own the 5) is very advisable to flash a modem built for your S4 flavour.
The above rule should apply to it too so, if the only modem available for the i9507 is the MH2 your firmware have to match or these issues reported will return.
Did you tested the "GSM Only" option to corroborate (or not) my hyphothesis? With this config, you should perceive no signal drops when waked. I know it isn't a viable operational mode but ... just for fun
Nice regards and keep sharing :laugh:

[HELP] [Q] No Mobile Data Signal

Hi,
I recently was getting frustrated with the ROM Gummy. ROM GUMMY: (http://forum.xda-developers.com/showthread.php?t=2563973) so i wanted to try something new and never thought i'd get a problem as when i flashed GUMMY it was so simple and everything worked.
However, when i flashed to the ROM S4 Google Edition: (http://forum.xda-developers.com/showthread.php?t=2544474) i noticed my signal / network won't stay connected. It may work for 2mins then disconnect - so i tried another ROM thinking it was caused by the S4 Google Edition.
I'm now currently on KOT49H【4.4.2】Google Play Edition (http://forum.xda-developers.com/showthread.php?t=2557353) and still getting no signal, only if i keep changing it to automatically find a network.
I've been reading it could do with Modems, or have i really messed something up and won't be able to fix my phone? I'm sort of new to this all so if you could explain more than tell me to do something that would be great.
Phone: Samsung S4 i9505

Any help would be great.

You have to flash a new modem for 4.4 like nb9. If you have a bootloader without knox, flash only the modem.bin file. If you have knox, flash modem and non-HLOS.bin. there's a nice modem thread in the general section.:good:http://forum.xda-developers.com/showthread.php?t=2192025

I have the same problem too!
Have you found a solution to it?
I have the same problem too!
Same here.
anyone got anything?
sheer terror.
Quite similar problem here.
I'm on Cloudy G3 1.2. My wifi is working fine, but impossible to turn on bluetooth. It stays on "connecting ..." then goes back to disconnected.
I think this is a hardware problem because it wasn't working either on stock 4.2 nor 4.4
I had same problem when Wifi/bluetooth MAC address are unavailable. It keeps turning on and automatically turned off after a certain of time. I tried to flash stock rom (4.2.2 & 4.4.2) and kernels as well (Cloudyfa & Dorimanx) and still the same result. In this morning, it's suddenly connected to my network and I am able to browse the net when I connected USB OTG to it. I was soon restarted the phone and the issue comes back, poor me . Now, I have no way to make it working again. Any suggestion on fixing the problem? Thanks in advanced!
I have the same issue.
Sent from my C6833 using XDA Premium 4 mobile app
Same here
I am definitely sure it's hardware related problem. I was so lucky when wifi + bluetooth could be turned on for few days but I need to turn both wifi + bluetooth on to get wifi working, the phone was pretty hot at that time and it only worked when I plugged my phone to wall charger at 100% battery. Sadly, it's not working now after many attempts. Need hardware replacement, I guess
it may be app lock or something
try disabling any app ,ocker or something like that, those things sometimes can interfere with the working of those two stuffs

[Q] Data Drops During Calls. Please Help.

Hello guys. I have the n900t, I am now running tweaked s5 base n4 style v6.0. And I run alot of n9005 ROMS as well. With that said here is my issue. For only the past few weeks ( month tops) every time i make or recieve a phone call my data drips down to hspa. The second i hit call and right before my phone rings is when it happens. After my call the data takes a very long time to jump back up. This is a new issue and i have no idea what it is. However, i did flash back to a stock ROM and the issue was solved. And i forget which rom it was but it was soley TE based and there were no issues. I did try to flash a modem but it didnt take. Is anyone else experiencing this problem? Or can anyone suggest a fix for it.
Thank you for your help.
bump.
Still having the issue. I tried to flash a new modem and it just failed anyway. Dont know if I should try a radio. I just cant fivure out why this happened out of no where. I was fine no matter what ROM I was running. Now...this crap. Please guys, 40 people saw this, can SOMEBODY please help.

1) Quite strange - your picture suggests you are on Verizon yet you comment about a N900T in the forum for the INTERNATIONAL Note 3. On what network are you? Are you aware that there might be network-specific factors involved which could only be visible for other users on exactly the same network in exactly the same region?
2) Try stock ROM (with corresponding stock modem) from a location with very good signal.
5 he physical device is an n900t, however, I am running as of now, the hyper drive note 5 port with n4 UI. When I do flash back to a full stock TW ROM all is good, A FEW TW based ROMs seem to be OK. Like this one, the calls do not affect the data signal. But most ROMs do effect it in that way. You said that it shows I'm running Verizon?
But I am very curious why all of the sudden I am having this issue. I have never had it before. Except with a few specific AOSP based ROMs. I just can't figure out what it is that's causing it. I have done vigorous wipes of the phone to no avail.
And I am in Philadelphia so there really is no place that is actually bad reception (except in the susubways of course...lol)
And thank you for your reply.

1) Your avatar mentions Verizon for some reason.
2) If it is all OK with the stock ROM then it is a problem with the custom ROM, ask in the specific thread for that specific ROM. Most likely it has something to do with the modem and the corresponding RIL.
So when ever a new ROM is flashed the modem is flashed as well. Unless the dev says otherwise?

Wi-Fi problem on cm13

Hi guys, I have installed cm13 on my S5 (klte), but I am experiencing wifi drops every few seconds and with screen turned off. I' ve tried installing different modem (BOK5, POJ1) and setting a different radio frequency, but none of this worked. Can someone help me?

I'm experiencing the same issue on my S5 SM-900F, when I upgraded from cm-13.0-20151025-NIGHTLY-klte to cm-13.0-20160203-NIGHTLY-klte. I flashed with TWRP-2.8.7.0. I read on another forum about flashing with nothing higher than 2.8.6.0 so I tried to upgrade when the 0204 came out, but no change. Anything new on this?
I've solved the issue, but I don't know how. I know for sure that this particular problem is related to DHCP, so I've messed up with my router configuration and I finally solved it. I suggest you to install TWRP 3.0.0.0 and make various try with your router configuration in DHCP section, good luck!
