Try some troubleshooting first.
Reset your Access Point/Router, or try a different router/ap. Flash back to 100% stock and do a "master clear".
I also find it useful to clear out the /efs partition after returning to Samsung ROMs after using CyanogenMod. Of course ONLY do this after you have a tested and safely stored a backup of your current "nv_data.bin" file. You have been warned.
Take out your battery and just let your phone chill for a few hours. That sometimes helps too.
Anyway, if after a complete flash to stock and master clear, and some troubleshooting with different access points you still get no WiFi signal, something may be wrong with your hardware...
From there you might either need to send it into a Samsung service center, or find a very technically minded XDA member to help you further. Good luck!

Im new to flashing roms, so bare with me. I flashed my first rom last week, using Andromeda3 and Ursa Minor #2 kernel, everything worked great except, i couldnt connect to 3G/H, even though it showed up on notification bar, tried looking for answers, i ended up flashing different modems to no avail. So, i flashed back to stock eclair, used kies mini to upgrade to Froyo 2.2 UCKB1, Data worked. I then flashed UCKB2 rom, data didnt worked) i tried wiping cache and all that, still no data connection, btw, wfi worked. So i flashed back to UCKB1, again, everything worked perfectly. The other day, i flashed Fusion XI and GB bootloaders, i must say i like this rom very much, but again still couldnt connect to 3G/H, everything else worked, although i havent tested the GPS yet, i am getting amazing DL/UL speeds through wifi. Anyway, i searched XDA for any answers i could find and pretty much tried them all, seems like only KB1 3G will work, but any custom rom out there, data hasnt worked even though i see it in notification area, i'd use market and browser, but would say could not connect. Am i doing something wrong/ missing a step?? I really like Fusion XI and dont want to flash back to stock. Any help would be appreciated.
Didnt know where else to post this, seems like other people dont have the data connection issue :/
That's weird.
Try flashing the kb1 modem on fusion.
I did try flashing the KB1 modem, but that too, didnt work. it only works if i go back to stock KB1 for some reason.
where do you live? what Carrier are you with?
have you checked your APN settings?
fill in your location and carrier/ device info in your signature/ xda user information.
I Live in Southeastern Pennsylvania. And currently have AT&T as my carrier. I tried APN settings, but not sure what to set it too, i have used APN Manager from the Market.
Try resetting ur apn settings to default. Then reboot.

how do u reset apn settings?
Settings, wireless and networks, mobile networks, access point names. Now hit the menu key and reset default apn well be on the bottom left...
Ok, tried that, still a no go connecting to data. I just flashed stock 2.1 then 2.2 update through Kies mini, i no longer have data connection even on official stock roms could this be a hardware issue??? gps sucks. ran a gps test using the app from market. other than that, everything else is working. what did i do wrong?
Hi folks,
I can't post in the dev section so I'm hoping someone can answer here instead. Searched imilka's thread but couldn't find anything that helped me. Wipe & reflash has worked for others but not me.
Wifi doesn't work for me. It worked when I activated it in the setup wizard after flashing the rom but after the first reboot it doesn't present me with any networks and it doesn't connect to the one I configured. I know the wifi device works because the mac address is identified in the status menu.
Also, battery time isn't very good. Less than half remains after being fully charged then left alone over night.
I have tried a full wipe & re-flash and also flashed the last version released yesterday. Does anyone have any tips or do I just wait for a new version? Seems weird that it works for everyone else.

Indeed, I didn't come accross any of these problems... I don't know what to say mate, might have something to do from whatever ROM you came from, some kernel remnants...but again, that's just guessing...
What I'd do in a situation like this would be to revert to a stock GB, use jBroid's kernel cleaner, and then try to reflash Chainfire's repack and back to CM. That's just what I'd do...
I'd try to do a factory reset first. That way you'll get another chance to setup your WiFi from scratch and see what transpires. If it fails, it's back to basics, most probably. Rooted GB --> ICS Repack --> CM9.
It's such a hassle to reinstall everything again.
I'm downloading a stock rom now and I'm going to try flashing the modem partition. Perhaps the modem in the chainfire repack I flashed before is not 100% compatible with my phone... Otherwise I'll just have to stick to mobile data.
Flashing modem made no difference so it's something with the ROM. Luckily I have a good data plan so I'll just leave it and see what happens in the versions to come. If anyone has an idea, feel free to let me know.
And thanks for your answers guys.
Suddenly it all works. Thank you Google. You're swell!
So I had some escapades today, I had my SGS running jellybean, then I tried to change the screen density and bang, bootloop. I panicked and after some odin fiddling managed to get it booting Darky using odin. I was in a room with no signal at the time so I thought nothing of not having any signal, even so I then went ahead and used recovery to reinstall my Jellybean rom since that's a bit nicer than the 2.3 Darky.
Long and the short of it is, I can search for networks in my options and it will find them, but when I tell it to connect to one it says "Can't connect to this network right now. Try again later"
I have tried later and surprise surprise it didn't work. I have tried installing a different radio, clearing the dvalik cache and fixing permissions as well as a few other things. Please can anyone suggest something, this seems to be a very uncommon scenario and it's stressing me out that I can't find any solutions.

Yeah I've checked them and unfortunately they all seem to be in order still, though there are a lot more settings than any website offers things to put in them
same problem
i am having this same problem on all cyanogenmod 7,9,10. i have tried many radio and modem flashes. i can scan and see networks, but i can never connect to them.
have you made any progress?
Problem is EFS folder which tends to do with IMEI.
To fix it you need to copy the backup EFS folder from your SDCARD to the root of your device. (/)
If you don't have a backup you'll have to ODIN back to stock and re-root....etcetera

thx
thank you for the response. I put it back to stock lastnight before bed so i will give this a try.
i have the gti9000m from bell in canada. I updated it through kies to 2.3.3 gingerbread and it all went badly. It would boot up and load to the os be on for a bit then reset. It turned out to be wifi problem, running it on airplane mode stopped it from rebooting. Then if i tried to turn on wifi it would quickly reboot.
So then i tired all the cyanogenmods, which worked it stopped rebooting all the time. however the wifi would connect and work for about a minute then it would drop. doing the
1.turnOn gps
2.turnOn wifi
3. turnOff gps
this would let the wifi work again for about a minute. I tried all the wifi fixer apk, and a bunch of wifi.zip mods, and then ping the router gateway constantly, none solved this problem. Very annoying because i need the wifi working for develpoment of apps. I have spent a great many hours on this problem. lots of people seam to have this problem but no solutions have wokred for me.
So, my questions are....
1. does your wifi work?
2. how the heck do i get mine to work?
back to stock
After going back to stock then upgrading connecting to network operators is fine.
wifi is still broken though
Yesterday, my phone just decided it didn't want to be connected to a network anymore. I was running DynamicKat ROM. It just happened out of nowhere and continues today. I've tried flashing different ROMS and they install fine, but I still can't register to a network. I believe I need to update the modem, but I'm not sure. I'm currently on baseband version ANK4, but I think I need to update to BOC4. Does this sound correct? Any advice would be great, and if you might point me in the direction of any files needed it would be greatly appreciated as well. No need to link, but just a general section where I could find the files would be helpful as I seem to have little luck with the search function here. Thank you in advance.
EDIT: Ehhh... Nevermind. It just started working again. I can't explain it. Suddenly I was connected again.
Always a good idea to check your APN settings if you are in a known coverage area with a new ROM. Been my problem 90 percent of the time

Funny you mention this as I run the same ROM and have had this occur to me whilst traveling around my area and in and out of T-Mobile "Dead Spots" which seem to be many...
Even called T-Mobile to report and best they could tell me is go into "More Networks-Mobile Networks-Network operators" and select - Select automatically.
A real PITA when you driving down the road and need to call out or re-connect your call with someone.
Note: I've had numerous issues on different ROMS similar to this so I pretty much blame T-Mobile and their service in my area unless someone else can chime in, I would be curious...

I had a similar problem on DK, except that it was unmounting my sim card completely & I had to reboot to get it working again. Happened every hour or so, very frustrating. I tried a different rom & the issue went away, so it's definitely something funky with DK which makes me sad cause that's my favorite rom.
I just reflashed it last night though & I took the precaution of completely reflashing ANK4 through Odin and redoing root & TWRP too, then flashing DK like normal. So far, so good(and it seems to have fixed the battery life issues I was having as well, yay), so you might try that method & see if it helps for you too. But be sure to back up your internal storage first cause odin WILL wipe it. Learned this the hard way, bye-bye all my pictures & titanium backups :/
Files I used can be found here.. BOC4 is for LP, so you should be fine with ANK4.
Hey everyone, so I just recently upgraded my Note 4 from KK to LP, but during the process, I had to flash the Baseband and modem before I flashed the LP ROM. I then flashed the ROM after I did that, and ended up with no network... I'm still able to make calls ONLY when I'm connected and close enough to the WiFi, texting is still fine I believe. So then I tried going through the process of downgrading to see if that would relieve the problem of my network issue, but it still isn't even working. Even after doing the process in reverse, flashing the baseband and modem before flashing my ROM.
I'd like to add that I did take apart my phone because my screen needed replacing, so I took apart my phone to see if I made my signal cables loose, they were, but then I popped them back in again, turned on my phone to see if that was the issue, and it still doesn't work, as well as my hardware back button doesn't work anymore so I have been using a nav bar to access my multi-window app.
I have tried flipping my signal cables, going from LP to KK, KK to LP, and reinstalling the firmware...
Edit: Whenever I factory reset in the stock recovery, I get an " Error:failed to mount /preload (no such file or directory)
Have you odin'd to stock lollipop?
You need to Odin stock firmware from Samsung, this will fix what you borked.
Then you can try again.

I've tried 2 fresh downloads of the stock firmware and it hasn't worked, but I will just download the file straight from Samsung this time to see if that could fix the problem. My new signal antennas I ordered from ebay are on the way and should arrive tomorrow. I'll then try that if this troubleshoot doesn't work because I don't have any 4gLte network at all, and it only pops up randomly and at certain areas I drive. I'm constantly moving and I could never have a stable connection, no calls, no text messages till I'm connected to the wifi:crying:
Edit #2: So I have installed new signal cables, and still not getting any 4G/LTE Network. I have constantly checked on my wires to see if it does anything to the network, but it doesn't. Still able to make calls on Wi-Fi only ): And I have used Odin to try and revert back to stock fully and no luck..
