WiFi problems on 4.4 stock i537 - Galaxy S 4 Active Q&A, Help & Troubleshooting

Hi everyone) I'am on stock official 4.4 update and I have problem with wifi (at&t i537 Active):
the phone finds some networks, but doesn't "see" others (including my home network, - and not only my, my friend's as well).
Tried to downgade to 4.3, but I couldn't even TURN it ON, because it just wouldn't switch to "ON".
Is there any way to fix the problem? (I guess it's a known samsung-software bug on i537)

[Q] Wifi not working properly

Today I tried the DoomLords method of rooting .244. After I downgraded the kernel to .423 suddenly my wifi stopped working (I wasn't able to turn it on - was turning off all the time). But hey I continued in rooting and after I rolled the .244 back I face another strange behavior of my wifi. Now I am able to turn on wifi, I am able to see packets flowing at the wifi notification icon but I am not able to load any page at all. And yes the wifi actually provides the Internet (my laptop confirms). Anyone facing similar behavior?
P.S.: I bought my Xperia in Japan if it somehow matters.
Edit: After reboot wifi always turn on itself.
I had the same problem, solved by flashing kernel from where I started.
What do you mean by kernel you started from? Original .244 from update or .244 from DoomLord? The original .244 would make me lose root permissions wouldn't it?
Original. 244, no you won't lose your root.

[Q] HTC One 801n - 4.2.2 update - WiFi issue

Howdy folks,
I received the HTC One (801n) earlier today. It arrived with 4.1.2.
Explored it for a few minutes, although I did not set it up fully - assuming I'd have to do it all over again following a 4.2.x update (I am coming from the HTC Desire, btw).
The WiFi was connecting without issues, then. I was also able to download the official 4.2.2 update from HTC servers.
The update was executed successfully - and surprisingly - I did not have to set-up the device from scratch. I then happened to notice that the phone would not connect to the WiFi network. I have my old Desire beside me (running a 4.2.2 custom ROM) and it has never faced those issues.
For a moment, I thought it was a hardware defect - but I recalled that the update from 4.1.2 was done OTA on the same WiFi network. I am, therefore, guessing it is a 4.2.2 bug.
Unfortunately, Google searches did not show any such issue specific to the One. However, there were 4.2.2-and-WiFi related issues in the One X.
I have tried a few full-resets in vain. Could someone please offer an insight?
Thanks, in advance, for your time/help.

Try removing the network in wifi settings and then reconnecting from new, it's not a issue with 4.2.2 causing this.
If that fails then after a base update (4.1.2 to 4.2.2) a factory reset is sometimes required after the update but this will mean having to set everything up again.

Thank you for the response. Did that, mate.
I guess you mean - 'forget' network and reconnect afresh? Yep, tried that. And did the factory reset too - to no avail.
Searched threads here, guess this is a first - in the meanwhile, I'll check out other Google results which indicated similar issues with the One X. Never owned one before, but shouldn't be all that different.

(SOLVED) Signal issues sice 4.3

Hi everyone,
since the update to Android 4.3 I'm experiencing some signal issues which makes me think about sending the phone to HTC.
First, after booting up the phone it connects to the GSM/3G network but after a minute or two it looses the signal for a while.
Second, every time i turn on WiFi the phone disconnects from the GSM/3G network. I'm not talking about switching from mobile data to WiFi, i'm talking about disconnecting from the mobile network at all!!! It says "no signal" and i get a little "x" displayed at the status bar every time i turn on WiFi.
These issues had not been present with Android 4.2.2 but with 4.3 it's just annoying.
I tried to avoid this by turning off the energy saving option but it's still the same.
Anyone with the same problem or even a solution?
Regards!
Phone goes in Unreachable state when power saver is ON after upgrading to 4.3
Hello All,
After upgrading my phone to Android 4.3, i am facing a problem i.e.when in built power saver mode is ON or any other third party application for power saving is activated, then when i am using my phone on 3G it works just fine but after some time when i put the phone in idle mode (screen lock & not using the phone) after some time when i again try to use my phone , my phone's data connection couldn`t start, and when i try to manually switch on the data connection through setting, it shows "Turning On.." & remains in this state. And during this scenario my phone goes in unreachable state, i have to restart my phone to make it working.
Pls help, is there any workaround to eradicate this problem, Am i the only one facing this problem or it is problem in all HTC one after upgrade to 4.3.
Thanks.

I bought a factory SIM unlocked HTC one with CID_102 and I'm using it with an austrian tele.ring SIM card. I didn't perform any software/bootloader/CID or whatever modification at all. I think the device has been shipped with Android 4.1.2, i don't remember. After Android 4.3 OTA update these problems occured. Before 4.3 OTA update i performed the 4.2.2 OTA update and used the phone for a while without any problems at all, until 4.3 OTA was available. Since then these signal issues make me crazy. According to system info the baseband version is 4A.21.3263.04_10.38m.1157.04L and the build number is 3.62.401.1 CL264544
If you need more info let me know!
Regards!
PS: I also performed a factory reset, but it's still the same.
Finally, there was a quite simple solution for this issue. I switched from "GSM/WCDMA/LTE automatic" to "GSM/WCDMA automatic" and this problem didn't occur any more.

[Q] i9000 can't 'see' my wifi network

I've just upgraded to Ressurection Remix Rom 4.4.2 (from 4.2.3 CyanAOSP), and everything is fine except the wifi. my i9000 finds some networks, but not mine! My network IS visible, so it's not that. But, given it finds other networks, i'm completely lost...All my other devices can see my network.
Has anyone else come across this issue?
PS: I don't think this is related to RR rom as i had the same issue with some other roms last time i tried to upgrade. Reverting back to CyanAOSP 4.2.3 resolves the issue.

XT1058 dead?WiFi

Hi guys i have a story to tell you... my WiFi doesn't work on XT1058 5.1... i thought was a Lollipop related issue so wanted to downgrade to 4.4.4 and see if the problem really was related to android version, but it isn't. I downgraded successfully from 5.1 to 4.4.4 with your tutorial, but the WiFi problem persist. Now i know i'm really screwed up becouse i tried i believe everything possible...
- Airplane mode
- Factory reset
- Cache wipe
- Full wipe
- Custom rom
- Custom kernel
- Android 4.4.4
- Different AP's and routers
- Delete wpa supplicant conf...
So i don't know what to do. Te specific problem is that WiFi can see available networks, but randomly some of them disappear and others show up, and when i try to connect for ex. to my home network, it says "connecting" and then "saved", with all networks happens the same. Does anyone has a clue, or maybe somebody in the same situation?
I have similar problem before. I tried returned to full 4.4.2 stock and no go.
In the end , I send it to moto and they replace me a new one which costs me 100 bucks.
I think It could be a hardware problem and might caused by running wifi hotspot too often...
