How is it that some i9505 can just flash ROMs such as Omega and get properly working wifi whereas I and many others still have to flash the modem/wifi fix to make it work? And apparently i9500 users don't have this problem. What seems to be causing this issue?
Hi guys !
I've just bought a samsung galaxy s4 (i9505) (a used one not new) and i flashed Imperium v7 and modem GNF1 and bootloader GNF1 (initially the phone was on stock 4.2.2 and the problem was already there).
My problem is that i don't get the network i rarely see two or three bars but it directly goes to zero (i can see the no network sign) and stays like that until a reboot (as said it drops to no network very fast).
So my question, is it software ? (should i flash the latest samsung stock firmware ?) or is it hardware ? (replace the internal network ship ?)
Or is it a common problem on S4 i9505 and no solution cannot be found ? :crying:
Could it be related to CSC ?
Anyway, i hope anybody can help me because i really like this phone and the rom that i just installed ..
Feel free to ask me about additional informations.
EDIT : I already tried :
1) the modem+bl FNDA => same result
2) force the phone to gsm only => same result (maybe better but even it solves the problem there is no point to not having 3g activated all the time)

It's going to be pretty difficult to narrow this down with what you've posted. You say the problem was "already there" when you got the phone -- how long did you use it on the stock 4.2.2 rom before flashing a new one? Did you see exactly the same behavior before you started mucking with it?
Hi ! Finally an answer So i used it for about 3 days and i really can tell that it is the same behaviour
My fear is that it may be related to hardware .. I am gonna try to flash the latest samsung stock firmware (with its csc and modem) ?
Anyway any idea ??

In general I'd say it's worth getting the phone to "current" stock, or as close to it as possible, and seeing what kind of situation you're in (i.e. if the behavior disappears or changes in any way). If you're seeing it on every configuration, it seems reasonable to suspect that it could be a hardware issue -- especially given that you got the phone used.
Perhaps someone else knows of a more definitive test you can try.
Hey ! Thanks for the idea ! already flashed the latest samsung firmware and same problem .. i stayed in touch with the guy that sold it to me so he took it back to samsung sav where his friend (who work there) told him that this is a famous bug in the i9505 4g serie and that the only solution is a
nvm restore (something like that). Of course he'll do it for free cause we agreed that if a problem come out he'll have to solve it on his own.
Anyway, i hope to get it back tomorrow or monday ! I'll let you know what happened as soon as i get it back !
solution?
Were you able to solve the problem? in case u were, how? i have the same issue sometimes i have 3g network, then it goes to gprs then edge, sometimes when im connected to wifi i cant receive calls, but i can do calls, any idea?
So I am from Canada and picked up the exynos version from a Korean seller on ebay.
Model number sm-n910K I actually have a huge problem. When wifi is turned on phone will reboot whilst in sleep mode after about 5 minutes if I turn off wifi it works fine. Note this happens even if I am not connected to a network the radio just has to be enabled. I am out of options I might rma it to the Korean seller but I think I might have to open a case with ebay, as these guys are being very difficult here is a video attached. I filmed it for 5 minutes but only recorded the last minute. http://youtu.be/ahLB0A2pCOM any help would be super appreciated thanks guys. I am at a loss whether this is software ie corrupt modem from improper driver installation at factory or just a faulty modem things I have tried already.
1. factory reset + cash wipe
2. Reinstall firmware using kies
3. turned off automatic scanning
4. turned off download booster.
The only thing that works is keeping wifi off. Any suggestions would be appreciated thanks.

Have you tried flashing with Odin?
Hey, I also have the SM N910K. What network are you using it on?
I have that version as well without that issue. Can you grab a picture of your About device specs?
Hello there i got same version SM-N910K i didn't have that issue with wifi , but i got battery drain , i live in uk and the phone keep searching for LTE- A ,
N910C with the Samsung SoC
I have the same Issue, i live in the US, I was in Malaysia and manage to get a N910C with the Samsung CPU, when I set the network to LTE/WCDM/GSM (autoconnect) it keeps serching for 4g networks, and it does not switch to lower networks even if available, which causes a huge battery drain, i had to set it down WCDM/GSM for it to get data. I did not have this issue with my note 3 which i also got in Malaysia last year, btw, the note 3 came with qualcomm cpu, and that leads me to believe there is a problem with the modem on the samsung SoC.

Hi! i found a solution where you can force your phone to go to GSM Only, WCDMA only or your preferred network type. In your dialer app type: 319712358. It will ask for a password and the password is 774632. And voila you can now choose what type of network you want to use. This will help with the battery drain.
Hi everybody..im from south korea. I have sm-n910k.

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!
Hello,
since I installed Nougat to my G4 Plus, first stock, then lineageos 14.1, I have problems with the wifi connections... every know and then, it just disconnects. I observed this behavior at many wifis, not just mine at home.
Does someone else have this problem? Which baseband are you using? Are you using dual SIM?
I got the baseband M8952_70030.25.03.62R.
Thanks for your help!

I'll concur with this. On both 2.4 and 5GHz as well as over 4G, my connection will drop every so often.
Nothing life-changing, but somewhat annoying. I'm on the Nougat RETUS radio.

I'm not alone. Fine. Which baseband version are you running on?

Same as yours; 70030.25.03.62R
I also have the same issue since the official Nougat update. Any ideas as to what it could be. Very annoying.
I have the same issue, it's very random and sometimes the wifi will not re-connect, I must manually connect to re-establish it. I have attempted to discover what if anything I am doing which may be causing it to occur with no real answers. I find it more than mildly annoying as it results in my connection timing out. Sometimes I may go hours without an incident, other times it is perpetual and constant. I believe that it may be caused by faulty hardware or firmware for the wifi radio as I have been incapable of discovering any evidence to suggest that this is widespread enough to be related to Nougat. That being said I did not have this problem until completing the official update on my phone which was completely stock at the time it was initially completed. My only course of action at this point is to A. rely on someone far more intelligent with this device to fix it. B. replace it with a different device
Same here. Very annoying when using VOIP etc. I tried both M and N basebands and different roms/kernels.
The problem might be due to the router settings.
Try to update firmware of check your wifi channel.
Wifi connectivity problem after ROM upgrade: baseband VS Llineage VS stock ROM
I flashed the newest clean stock firmware NPJS25.93-14-18 on XT1625
baseband M8952_70030.25.03.62.02R Athene_RetUSA
Then I flashed Llineage-14.1-20180815 and observed problems with Wifi, mostly with old WEP protocol.
Then I downgraded to stock ROM NPJS25.93-14-7-8
baseband M8952_70030.25.03.64.01R Athene_RetUSA.
Wifi connection seemed to be OK on stock NPJS25.93-14-7-8.
So is the wifi problem resolved with baseband M8952_70030.25.03.64.01R?
Not exactly so. After I flashed Llineage-14.1-20180815 with GApps (nano) , the wifi problem re-appeared despite having "good" M8952_70030.25.03.64.01R
So baseband is the same, but Andoid 7.0 stock ROM handles wifi better than the latest Lineage. Or is Google apps and software is involved?
The problem was discussed on Motorola forum
The problems seem not to be limited to Moto G4 only, but clearly appeared after upgrading to newer firmware. It might have something to do with tightening security in resent Android and Google firmware as Wifi WEP protocol considered outdated and of low security . However, some people reported problems with Wifi WPA protocol, too
