- Device : SM-N900S
- OS : Lineage OS 18.1 (2021/07/14)
- Symptom : Wifi or Data internet connection lost occasionally
Good evening. I would like report an issue regarding wifi and data internet connection:
1. Wifi is connected and internet works ok. but when I am away from wifi network, my data(4g/lte) connection is lost, which should have automatically been connected. The signal strength is active, but no 4g/lte. Turn on/off of data connection as well as reset network do not work. Only reboot works - 4g/lte is active and signal strength is ok, internet connection is fine.
2. Then when I go nearby wifi networks, the device does not catch any signals of wifi network. Literally none. Only reboot works.
3. This symptom occurs "occasionally" once or twice a day.
4. Reinstall bios, OS do not work.
5. I hope it works well soon.
Thank you.
Report it to the roms thread as required .
Developer unlikely to read random Q&A .
BIOS ??? what do you mean its not a PC .
Network/ Wifi may be wrong baseband .

Thank you for the reply. Why did I think that TWRP is bios? haha. I will repost to the roms thread again as you recommended. Are there any baseband patch or firmware for lineage os 18.1/sm-n900s? Thank you!
The issue solved. Well, actually not solved. I have installed crDroid 7.x rather than LineageOS 18.1. It has been two days, and so far so good. It is quite interesting that what I know is crDroid is based on lineageOS kernel. but what exactly makes the difference? Later, I may try other OS too. Thank you for all developers! Dear manager, you may delete this thread

Mobile internet does not work to failure . Prior to the first number flashing Inet worked with enthusiasm. But after put CM 11 , then it stopped working . Sometimes appeared icon "E" and "H" icon beside the network signal . But even when these letters were , the Internet is still not there . In the general information number " data transmission mob. Sharing " is eternal " connection " or " connected " , but an Internet or not. Then moved on to the same CM 10.2.1 because thought because nightie , and no internet . Reflash radio module , firmware flashed correctly ... But an Internet and has not appeared.
What could be wrong?
To correct only reflash radio and switched to a stable CM 10.2.1
Tried to roll back to stock, still did not help. EDGE icon appeared on the second, but then disappeared. Internet appeared as yin.

Might sound silly, but did you check your APN? And is it selected? (is it "checked"?)

Ahah, yes. APN is right and checked.
How did you reflash back to stock? Did you flash the official Google images or restore a nandroid? I would suggest reverting to the stock images and trying again.
Can you verify the SIM is working properly with the APN you are using in another device?
Can you connect to your routers interface (usually an address like 192.168.178.1, check the bottom of your router or your routers manual)?

Yes, I flash official Google images.
I verify the sim on iphone and there internet is worked...
If you do a *#06# in the dialer, does it show a valid IMEI number? 16 digits beginning with 3564?

Greetings, today I installed the new nougat 7.1 rom for my jiayu s3 [MT6752]. But I couldnt connect via wi-fi, and no networks appeard to connect to.
So, I switched back to the older rom I had installed (AICP11 - mm) and the problem persists. Imei is fine and I can connect via mobile data, but wi-fi keeps searching and searching without results.
Does anyone know what is this about?
All the help is appreciated
Thanks in advance
I am not sure about it, but I think I have read somewhere for that problem. Other users re-installed Rc4, and some other used another modem from the thread that it is about modems. Check it out.
JiaYu S3, Nougat 7.1
Well, it looks like its software related so what I'm going to say may sound out of point, but anyway, you can check the physical connections of the wifi antenna (you will have to unscrew the phone).
Hello!
My Oneplus 5 does not connect to any wifi networks. It is able to see all wifi networks in the range, and is also able to save the network if the password entered is correct, however, it won't actually connect to any network that is saved. I have tried using advanced options while connecting to a network to change from DHCP to Static settings, but it still won't connect to any network. I have also tried changing the wifi band frequencies (2.4 and 5 Ghz individually) to connect to a network but that too does not help. Mobile Data and carrier signal on the other hand work flawlessly, and so does bluetooth connectivity, NFC and personal hotspot (which is why I am very confused). I should also mention that when it fails to connect to a saved wifi network, it occassionally displays "Disabled" under the network SSID (replacing "Saved").
I have changed 3 different ROMs (LOS, stock OOS and No Limits ROM, even replaced the stock kernel with blu_spark r69 when I tried using No Limits and stock OOS to try and see if that fixed the problem), but the phone just won't connect to any detected/saved network using any of those ROMs. I have reverted it fully back to stock now (OOS 4.5.14 and stock kernel and stock recovery) and am still having the same problem.
Sorry if this issue has been solved before and if I am reposting something, but I really need this fixed ASAP and am not able to find a working solution after searching the forums and googling the whole day. Please help me! Thanks!
Edit: finally fixed the problem thanks to Ivints and PeterGuru. Check out the post that Ivints linked below (especially the comments in page 2 of the same)

Thank you so much Ivints! I'm trying to fix it right now with the solutions I got from the post.
I'm having exactly the same problem that the guy who started that post had. I'll let you know when I fix it and everything goes well again! Thanks again, bud!
if you want to stay on Nougat look for the O2N revert flash file it's in the Oxygen 5 beta threads that will let you get back to a nougat based rom.
The Oreo update touched other partitions outside of /system so those wifi drivers don't work with Nougat anymore

aww you should have totally read this post and the one that Ivints linked to fix your problem, i.e. if you had a similar problem.
Glad that everything is working out for you properly now.

I see... I'll look for that thread and get the flash file! thanks! I'm currently using xXx's No Limits 9.2 OB03 ROM with bluspark 3.2.1 recovery and bluspark r77 (Oneplus 5). The only reason that I feel like reverting back to Nougat is that I want to be able to use Xposed again. So i guess I have that option in hand not too! Thanks, bud!
Hello there my friends, i have a problem with my op5
its about wifi: it doesn t see my wifi anymore. idk why
it s been connected to this wifi 2 years ,even after switching roms kernels, firmwares
and now , it doesnt see the wifi no more, actually it sees it, in `Saved` section, but when i press on it to connect
it says ` not in the area` but my other op6 its connected no problem
and i even tried through qr code, it says ` check ur connection and try again`
Just one add-on cause I was just a few minutes away from formatting my data. My OP5 unlocked rooted, rest stock, wasnt connecting to my home wifis (2,4ghz and 5ghz). I flashed a full ota zip. I deleted wifi bluetooth via backups settings.
But I found out that connecting to an iphone hotspot worked. So I entered manually the network SSID + password although the same network name was already in my wifi list (with marking: "saved"). I then clicked on the second "new" same wifi and it directly connected to my home wifi. Same happened to the 5ghz network. I then deleted the old 2 ones.
I have no idea why this happened, I only tried to get VoLTE/Wifi Call running with the magisk module. This might changed sth but I dont get the connection here since there should be no interference...
I am faceing weird problem with 5ghz wifi connection .
As soon as i try to connect to 5ghz wifi ( 2.4 ghz works fine all the time ) after connecting the connection drops within 30seconds and AP to 5ghz disappears , only reapears if i reboot or turn on and off flight mood .
But the intresting thing is 5ghz connects and works find when the phone is in flight mood .
Any solution please ??
Have you tried another kernel? If you have Oreo and are rooted (as you've described) you could try the mk2000 kernel in the V20's development section. There should be an Oreo version of it available.

Yes actually , i was on stock kernal yesterday with same problem , today tried mk2000 v2.0 kernal and still same problem .
From all my experience i noticed that when in fligh mood ( no GSM ) 5ghz works flawless , as soon as GSM Signal appears 5ghz AP disconnects and disappears untill phone restart .
Could it be frequencies interference of GSM signls and 5ghz ?
Just a suggestion, do you have any of these checked in developer options? Could they affect what your experiencing? I would assume you want them unchecked.
Again, just a suggestion that's simple enough to try.

Hello. I'm desperate to ask for this problem to be solved. I already flashed my phone with fastboot using miflashtool and went successful. The phone booted up to miui 11 logo however just after 1 second "system isn't responding" came out now phone was unable to search for Cellular signal as well as wifi signal is also not able to look for my own wifi.
After this, I tried to flash also the custom rom like Pixel Experience, EU ROM Stable and also Global rom but still they can't catch any wifi and cellular signal.
I hope someone can help with this. Thank you so much!:good:
