If you have followed the install instructions exactly as they're outlined in the first post (i.e., Full clean flash, re-installing modem etc.), go to Settings > under Wireless & Networks, tap ... More > Mobile networks > Access point names (apn's) - check the latest apn's from your network provider and add them in, if different than what is shown.
You could also try the 'Network settings reset' under the 'Wireless and networks' header and see if that helps.

I've tried that last thing, but I'll try that first thing once I back it up

I've switched to havoc and the wifi works now. Thank you.

[INFO]What to do when you cannot access 3G

I had a problem accessing 3G when installing a new rom. After flashing a few roms and finding out that roms were not the issue, as well as applying a few radio updates and changing radios and a google on the internet, I found out what was the problem. The access point was not set up. Defrost's rom based on cyanogen mod had the massive APN List preloaded, hence I never ran into that problem. However, most roms did not.
Here's how to set it up
Creating a new access point
When you need to add another data connection on your phone, obtain the access point name and settings (including username and password if required) from your mobile operator.
1) From the Home screen, press MENU, and then tap Settings > Wireless & networks.
2) Tap Mobile networks > Access Point Names.
3) On the APNs screen, press MENU and then tap New APN.
4) On the Edit access point screen, enter the APN settings. Tap an APN setting item to edit it.
5) Go to this site and find your mobile network company name
6) Modify the settings as said
7) Press MENU and then tap Save.
You should now have working 3G!

I thought you already had a thread on this and a mod said to post this in general?
If you think its apn problem, install the rom it works on and then download apn backup and restore. Use that to backup apns and then when you install a rom you want, use the same app to reinstall the apns you backed up.

Good advice, but this doesn't need to be in development.

Samsung Focus S - USB Tethering: Confirmed Working

Anyone get this working, the old method doesn't work. The computer found the phone and installed the modem. Does the Samsung Focus S have different connection strings?
In the diagnostic screen there are more options than the Samsung Focus:
Zune Sync
Modem, Tethered Call
Modem, USB Diag.
Zune Sync, Modem.
Modem_QC, USB Diag.

internet sharing was loaded by default on my system settings.
Turning it on will trigger AT&T to enable the Tethering Plan. When I turned it on few months back on my Focus AT&T sent me a card within a few days stating they would turn on tethering automatically unless I called to tell them no. I used the USB tethering prior for 6 months with no word from AT&T until the I turned on internet sharing.

That will not prevent it at all. Without that you won't be able to turn it on, but once you do turn it on AT&T will message you saying if you continue you'll automatically be enrolled in a tehering plan.

The exact thing happened to me. I've USB tethered my phone since January no problem and a week or two after trying internet sharing I got the message from AT&T. I figured the internet sharing triggered that but in fear of loosing my unlimited data plan I haven't tethered using either method since. Have you used USB tethering since getting the message with no problem?

Yes, few months with no issues. I called AT&T yesterday and asked if any more "tethering" triggers came through and they confirmed no. I am 100% positive the internet sharing in system settings triggers the plan if you don't pay for one.
The USB method that original worked for the Samsung Focus doesn't work on Samsung Focus S. I have tried on 3 different computers that worked previously; I can easily connect my Samsung Focus but receive dial-up error 628 or error 619 on the Focus S, the strings have be different. The main reason I upgraded was the 4G speeds which are amazing on this phone.
I have uninstalled all the drivers, deleted the modem and reinstalled with no problems. I just can not get past the error. We need to get us new Samsung Focus S owners our modem back
Got it working...

Awesome! I'm tethered now and I'm trusting you that this is safe!
I didn't need to delete my old modem or uninstall any drivers. I plugged my phone in and it didn't even install new drivers but this worked right away.

I think I changed too many settings in my modem which caused me to uninstall everything. Hopefully the quick route will work for most people! I am glad you got it working! I have never had AT&T notify me this way, only using the Mango tethering option.
Hopefully we can add this to a sticky and under the Samsung Focus S section when it is up and running.

Good job. The Samsung Focus S forum needs to go up soon!
Hello is there any way to make usbthetering on Omnia7 available? wolud be very nice
Have you tried following the same steps used for the Focus / Focus S?
Alternatively, have you tried a search?
USB tethering for all gen1 devices, even things like the DVP which otherwise have very little homebrew, has been known for many months. I don't recall if you had to tweak it slightly for the Omnia7 or not, but I don't think so.

worked for me, I have a focus flash!!!!!! Adding the code in the advanced properties worked and the connection was no longer refused and connected right away
Hmm, I seem to have a problem. I get the phone set to "Modem, Tethered Call" no problem, but when I plug the phone into the computer the install new hardware wizard fails with the message that it "can't find the necessary software."
Any ideas?

That did the trick. Using my phone as a modem right now... thanks!
Are the instructions in this forum so that I can use my 3G connection on my Samsung Focus S by my laptop that doesn't have Internet?
Or is it the other way around so that I can use my laptop's Internet connection so that my phone will be able to have Internet as well - just by connecting to the USB port?
I'm assuming it's for the former but I'd also like it if someone could point me to the latter.
It's for the former. For the latter, that's built-in; just connect the phone to the computer by USB and start the Zune software. It will create an Ethernet connection over USB for the phone to use, off of the PC's Internet connection. You could also use Internet Connection Sharing from the PC over WiFi, and connect the phone to that (it may help to use software that causes the PC's WiFi to appear as an access point; I'm not sure if the phone supports Ad-Hoc networks).

Awesome! I didn't know that Ethernet connection over USB was able just by having Zune and the Windows Phone. Tried it and it works great!
Would that only work with Windows Phone or any other phones/devices I use while Zune is running?

BTW you should post in Galaxy Note 2 Q&A forum ( use xda device search engine to locate it)
A modem change might give you results only after you have checked your APN ,
Quick Guide
First Check your settings > about phone > status > your phone number ( IF UNKNOWN )
You won't be able to send SMS by any third party sms apps or Have a Network connection
Solution :-
You need to edit that "unknown" number to your phone number, by putting your SIM card on any old phone that has a "my number/owner number" option, (most old phones do). Edit and save it to the proper phone format as your Sim Card number (Example: +63913XXXXXXX). Now put the SIM back to M110S, to solve this problem.
Than check your system settings, in Settings > Wireless & Networks > Mobile Networks > Access Point Names.(APN) as provided by your Network provider . If your Apn is not set, you wont be able to have data connection, so set it first
If still no data connection, Common Trick is to toggle WIFI and Airplane mode or
1. Turn ON WIFI
2. Set the phone to Flight Mode
3. Power down the phone for a few Minutes
4. Power it back up
5. Turn OFF flight mode
6. Turn OFF WIFI
Should get Data back

APN
Try creating a new APN -> Thethering & Networks -> Mobile Networks -> Access point names -> New APN enter a name, same APN and Port Number as your current settings and save( Don't add anything else). and select it as your access point.
eg- name - newapn
APN - ppwap
Port -8080

I did deleted my APN when i did factory reset and entered a fresh APN. Still the problem persists. :crying:

how to specify different APN?

I just installed the latest pie lineageos ROM on my Samsung Galaxy S5 (Sprint version). I am unable to choose or add an APN through the settings app.
I can see (surprisingly) that the Tello APN (which is what I need to use) is in /etc/apns-conf.xml.
Is there some way to enable APN selection in the phone's UI? Or, is there some way to manually edit config files on the phone to specify my desired APN?
Thanks.

No menu option to get to APNs. The closest thing is "Carrier settings", and when I select that, some error occurs, because I get kicked back out to the main settings menu.
