Data connectivity problems have been reported by several people with CyanogenMod. I personally experienced it with CM, SlimBean....
Have you tried AOKP? I'm running 4.2.2 and have not had any data connectivity issues with this ROM. This is an unmolested install...no APN tweaking.

AOKP
I am downloading it now & will report the result

Same result
Hi
I just flashed AOKP same result, when i toggle mobile data it say connected in setting > about > mobile network state , but no internet!!!??

[Q] GS4 i950 CM 10.2 Nightly LTE problem

Hi all,
I can't get LTE data to work on the latest CM 10.2 nightly (cm-10.2-20131007-NIGHTLY-jfltexx). It establishes a connection to the LTE service according to the device status menu, but when I go to browse the internet, it says no data connection (there is also no valid ip address in the device status menu).
Am I doing something wrong? Or do I need to reset my carrier settings or something? I am with Vodafone AU. I have also done a full data wipe, and I have flashed both the MGA LTE modem and the regular MGA baseband modem.
Thanks
OK solved my problem. The APN settings were wrong, changed it to match the touchwiz settings and it has worked.

[Q] Phone cannot connect to Mobile Network (CM 10.2)

Hello, I had successfully flashed my LG G2 (D802) from stock to CM 10.2. The sim card was recognised and joined immediately to EE (UK - Mobile Network *T-Mobile/Orange*). During Christmas I tried flashing a new nightly from Cyanogen Mod (11), however I had an outdated clockworkmod version (even though I couldn't update it further). I couldn't launch back to CM 10.2, as the data was wiped when trying to flash CM 11 (Nightly).
Due to not having a back up file, I reverted to factory settings first, then wipe 'all' data off my phone using ALL the options avaliable on CWM. I then had to use 'adb' to push CM 10.2 back into to the phone. It successfully flashed and it was running stably. During the set up pages, CM gave me a pop up to look at sim card instructions to 'get it working', i thought this was a minor problem and couldn't to set it up. When this was finished, gave me everything (WI-FI, bluetooth etc.), however I didn't connect to my Mobile Network 'EE'.
I set 'Data Enabled', Network Mode: WCDMA Preferred.
I tried automatically/manually connecting via the CM settings, but response was 'Could not connect to this network. Please try again later.'
So no luck so far in connecting the phone function back up.
I would be truly thankful if everyone could help with a solution. ^_^
Many Thanks!
I've found out that the phone is locked to a HK network, but I am currently studying in the UK. The problem is that I can't unlock the phone in the UK with using the HK network; I have a HK sim card as well as UK, but since the phone is locked I can't use a UK sim card and the HK sim card doesn't seems to register UK Networks.
Anyone got suggestions to bypass this?

Any custom rom has wifi problems.

Hi guys,
I've got a Samsung Galaxy S4 with this custom rom.
Unfortunately, the wifi connection drops or doesn't even work at all. I downloaded another custom rom, Cyanogenmod 11. For me, this rom also has the same wifi issues. So I followed this tutorial here on XDA to update my modem and bootloader to XXUHOF2. (I also flashed the wifi fix for that bootloader in pda/ap).
The modem and bootloader update worked, according to these screenshots: (See attachments)
But the wifi connection still drops or doesn't even work at all.
Also, the mobile connection and wifi indicator have sometimes got an exclamation mark next to them. (See attachments)
When I go back to stock, the wifi works perfectly. (But I don't want stock because I hate touchwiz).
By the way the mobile data, texting and calling also works fine.
What do I need to do to get the wifi working?
Thanks in advance,
Twitmuck.

WiFi issues after Stock ROM. Won't remember my networks.

Hi,
Until very recently, I used CM 12.1 ROMs on my Note 3. I decided to go back to the Samsung Stock ROM for reasons (N9005XXUGBOK6 N9005H3GGBOI1).
Since flashing however my phone refuses to remember the Wifi networks I connect to, and I have to enter the network key each time.
This is rather annoying, and means that I am using more of my data allowance than I should be.
I would be grateful for any advice.
Regards,

Oneplus 5 does not connect to wifi networks

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

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...
