THE Thread for Connection Issues on WM 6.1

I've noticed a lot of people having problems being with T-Mobile and having the new 6.1 ROM being used on their Dash. Now even though I don't know the answer or connection settings to get this to work, I though I'd take the liberty of starting a SINGLE thread about this known issue, so our friends don't have to go digging through the threads to find what they need.
I've tried to update the GPRS and Proxy connections to what they were before I updated, but there is no "E" in the top right corner. When I try to use Windows Live or any other data service, then the "E" pops up in the upper right and soon after, 2 arrows signifying a data transfer shows up, but nothing ever happens and it times out.
Has ANYONE gotten their Data Connection with T-Mobile to work with this yet? I'm going to call T-Mo to get the settings, but I though I'd check here first. I'm not payin' $19.95/month for nothin'.

First, go to Settings > Connections > Proxy and delete everything. Then go to Settings > Connections > GRPS and delete everything, then add an item:
Description: Tmobile Data
Connects To: The Internet
Anything that says DNS: 0.0.0.0
Access Point: wap.voicestream.com
Leave everything else blank.
Then configure another item called Tmobile SMS, with the only difference begin that it connects to "Wap Network"
Did this work? If it does not work the first time, restart and try again. It works for me

Got it working. Thanks for the help! I had alternated between those 2 settings to try and get everything working. Never thought of just adding both of them. Duh!

Your welcome. To be honest, I did not know that you had to have them both configured - I have just always done it that way because thats what the TMobile site told me to do. Now I know they both have to be configured You have just saved me a future headache

[Q] Is Wifi Calling Missing in CM7 on purpose?

I've done several Google searches on this topic as well as focused searches on the CM and XDA forums; I figured it was time to just ask the question myself.
So I noticed that Wifi Calling started missing in in the CM7 nightlies sometime after #21. I ran across someone from the CM forums who saw theirs returned after his upgrade from #28->#30 (which I did not see on mine even after a full wipe).
Is there a setting or condition on my phone that prevents me from seeing/activating this feature?
Thanks in advance,
Reg

I've been running CM7 since build number 0 and now I'm on build 31, I have flash every nightly released and have always had wifi calling on every single build.

So I did a clean install of #21, which had wifi calling, but when I upgraded to 22, it was gone. Might anyone else know what I can do to install?
Thanks,

When you are upgrading, what are you wiping? You only need to wipe cache.

I've tried multiple things: cache wipes, no wipes, "clean" installs, manually formatting each mount point. None of that matters for me. Wifi calling only shows up in builds up-to-and-including 21; after that, it just vanishes.
Thanks for trying though, dude.

As i installed the CM 7.0.0-RC1 with Nightly version 2. and i found the same thing means WIFI is not working but when i press the power button and found the option REBOOT and select this option and then again i select the option REBOOT, Phone rebooted and then turn on wifi and it started working. so all you have to do is to Reboot the phone as i said. you will hopefully find your WIFI option working.
as i had the same.

Yes, it is well known that a first reboot is required to get WiFi working on CM7 right now. OP's question, however, is about the missing WiFi calling application.
OP, that's very interesting that it won't show up. So if you do a clean full wipe and install of something like RC1 or higher, you still don't get WiFi calling? Mine has been in there on every build... hmm..

I did'nt Wipe the Cache , I did the reset factory settings option. and install the CM7.0.0-RC1 with nightly version 2. and after done i found the wifi option is not working.
as i told when i rebooted the phone and i found the wifi option working.

Do you have a g2 or a desire z? I am looking at the changelog right now and it says that wifi calling is only installed on the g2. I'm assuming that you have a g2 since you are asking about it, but just throwing my 2 cents.
Maybe the rom is thinking that you are running a Z instead of a G2. Idk. It might help. More than likely not, but it's worth saying IMO.

I know what you are saying . but i tried everything after that i said so that wifi calling is working. as you find the WIFI connection then go the wifi calling app and then enable it and connect to tmobile network so that you can use it. but if you are in such area where Tmobile network's service is bad then might there be a chances to have no connection with wifi calling even if you have connected to wifi network (Internet)

now i am store working and i have a wifi at my job too. so i connect there carefully once again and checked everything and when i open to the wifi calling app and connect to T-Mobile Network for wifi calling i see after connecting to Tmobile via wifi radio signals turn to zero and when i disconnect it singals first had a 'x' on it and then they turn green. so make sure you are using the tmobile network then you will be able to use wifi option.

No 3g or wifi

Good morning,
I've been reading the forums for a while for solutions and tips but I am stumped on this one.
So I had stock Epic 4g (SPH-D700) on the Sprint network that was rooted and running CM 10.1 just fine. My USB connection broke so I bought a new motherboard so that I could switch to Cleartalk wireless, which required a connection for them to flash. They flashed the phone and while in stock, 3g data worked fine as well as phone calls and texting. Even stock though, with new motherboard, wifi did not work. It wouldn't even turn on to search for a connection. After rooting and flashing CM 10.1 while on the new Cleartalk network, 3g data now does not work and it gives me this error "unable to resolve host get.cm no address associated with hostname." Wifi still behaves the same. Calls and texts still work but I currently don't have any way to connect to the internet via 3g or wifi. Please help! I don't want to go back to stock just for connection.
Thank you!

Sounds like 2 issues here.
1. You probably forgot to connect the wifi antenna when you swapped motherboards.
2. You don't have your APNs configured for Cricket after flashing CM10.1.

1. I will double check this as soon as I can.
2. Any idea how I can go about configuring the APNs? I saw a solution where I backup the APN's with an app while in stock then restore once CM 10.1 is flashed. Will this work for me?

****, no it's not lol. Sorry, I misread. There isn't a ClearTalk thread in our dev forum that I'm aware of. You may want to search the entire XDA site and even Google for that carrier's APN info.

No problem. I will try some things and update this thread with the progress. Thanks again!

So it isn't the hardware connection for the wifi problem. I checked everything and it still didn't work. I even reinstalled the old motherboard to make sure I had all connections right and the wifi worked fine. I just discovered the Bluetooth also doesn't work.
I haven't tried repairing the APN yet, I will update after I try.

Using "APN Backup and Restore" did not work. The app runs and says it is successful but doesn't actually restore the APN's. Or it does and that isn't the problem.

VPN and Tethering not working on rooted device, will custom ROM fix that?

I came from a GS4 where I used Private Internet Access VPN and WiFi Tether Router. On the Note both services connect but do not route any traffic, my thinking its related to knox. Would a custom ROM fix that? At this point I have to either trip the counter or take this thing back for an iPhone 5S before the jailbreak is patched.
***FIXED
All that needed to be done is to have this setting changed, I can use WiFi tether along with VPN running at the same time so I never hit my hotspot limit because Tmo cant tell if the traffic is from a phone or other device.
To change your APN, simply navigate to Settings > More > Mobile networks > Access Point Names. Select your T-Mobile APN, and scroll to APN protocol. Change this to IPv4, and then save your APN.

I have been having issues with the same vpn too. How are you getting yours to connect? I am running Jedi and I can't even get it to connect to the vpn. I tried cm11 too and same thing. I have changed my apn from ipv6 to ipv4 but everything else is whatever came with jedi and cm and stock. On my Nexus 5 I can use it just fine with tmo... so unsure what the issue is.

I'm just using the app from the playstore with the default settings. But I did install a custom ROM, Darthstalker version 6 and it still does not work.
Now the counter shows as tripped whenever the phone is restarted, I hope tmo will take it back because I'm just going to try to trade this for a 5S.

Are you using Fabios WiFi router? If so make sure to check his configuration page for the device. Yes I am not on WiFi, just came back from a 2 hour drive while my friend was tethered to my phone on his iPad.

T-Mobile is being very tricky and devious with blocking tethering

So over the past week, I've discovered that Fabio Grasso's Wifi Tether Router app has stopped working for my t-mobile LG G3. I tried different configurations, tried e-mailing the dev, and I tried changing the APN. None of it worked.
(Regarding the APN, he says to change T-Mobile to IPv4, but I can only change it to IPv4/IPv6. If I try putting solely IPv4, then my data connection drops out entirely).
Moving on, anyway, I've found out that if I use the Wifi tether router app, I can only access HTTPS sites. For example, any banking site, facebook, google, yahoo, etc. all work as long as I stick https:// in front of it. However, anything else won't work (like xda).
So I can only assume that T-mobile is somehow blocking that traffic...and now I need a way to disguise my own traffic...
I tried connecting through OpenVPN through a VPN I had, but even that won't connect properly.
And before anybody says to install the stock tether app Mod, I'm still on the stock recovery so I can't flash anything.
I'm on the stock recovery (but I'm still rooted) because I prefer to mess with my device as little as possible. I want to keep it as stable as possible, and having a stock recovery means I'm not tempted to go out and install new ROMs or flash anything that could potentially brick my device.
So...does anybody have any solutions? This is like a tug-of-war with T-Mobile, and right now it's in their favor.

This is old news. T-mobile made it knonw they would start blocking tether if it is being mistreated. Devs will have to become more clever and trickier with their apps. With this in mind, just be careful. They said anything that goes against the contract you signed regarding their data usage / tethering will cause your tethering to be cut of if data not cut of for that month (can't remember the full detail)

Well this is the first time I've experienced any issues. I have a total of 11gb usage this month, and it's almost over. 95% of usage is on mobile, so I see no reason for them to even become suspicious. I doubt I'll be cut off. The "warning" they gave a couple weeks ago referred to like 20 customers or something that were using hundreds of gigs of data.
In any case, I really hope devs can find permanent ways around this.
By the way, I don't really understand ports/encryption, but I know that "443" is secured, so how possible is it for me to just manually make everything go through that port?

Download THIS zip and extract it then find the APN XML and replace your old one with the one in the zip you extracted. Boom you should have full ipv4 for your tether app and vpn.
Make sure you rename instead of completely replacing. You'll probably need to restart and if it still doesn't work that means dalvik needs to be wiped and your Sol unless you want to install twrp. Unless a app exists that can wipe dalvik without recovery.

Okay now this is getting interesting.
Although this is getting into brick-able territory. With my LG G2 when I messed with build.prop I almost soft-bricked it.
In any case, I can't seem to find out exactly how to modify the APN XML, and a quick google search is just showing me "apns-conf.xml", is that the same thing? Is it just a value inside build.prop?
Also, the warning on the xda mod page says "TETHER BROKE FOR NOW". Does that only apply to stock tether or something?
Edit: Nevermind, looked through the zip file and it turns out the apns-conf.xml file is under system/etc.
I'm still worried that this could cause some damage though. Lemme just double check - not brickable if I just replace, correct? and Also, I can create a backup of the apns-conf.xml and restore it without any issue, correct?

Yes stock tether but the APN in that zip won't wreck it its the build prop edits that broke built-in tether. You won't need to do any builp prop edits just swap out your APN.XML for the one located in that zip.

I looked through that entire thread last night, and I discovered that somebody was having issues with Wifi calling after installing the mod, so I got nervous and backed out even though I've already created a backup of the xml, lol.
Do you know if wifi calling + texting still works? That's a dealbreaker for me if it doesn't, because I use wifi calling/texting all the time.

apns-conf.xml does not break WiFi calling or texting. This is where the tethering APN is stored. What could break WiFi calling is modifying build.prop.
I'm pretty sure they have deep packet inspection on their network and they can tell exactly what kind of traffic is being done. Any traffic using the fast.t-mobile.com APN that doesn't look like mobile can be very easily blocked. You can't deep packet inspect SSL (https) traffic, so I'm not surprised this works but everything else does not. An SSL VPN would get around this.
I'm using the PrimeTether mod which basically modifies the stock tethering to use the mobile APN so that your data looks like it's coming from the phone. WiFi Tether Router might be doing something different that T-Mobile can see and that's how they are blocking it. It actually might be that WiFi Tether Router is tethering using IPV4. The stock tether app tethers with IPV6.

The prime tether changes one line in the framework-res to the fast APN. At least that's all I had to do. I never released my version because auto beat me to the upload.

He changed more than that. I had made that change to framework-res but was still having issues with my stock tether. There's a check being done by the tether process. I believe he modified the smali code to get around this, just like it had to be done for the G2.

Are you sure? The change plus the APN XML I use worked flawlessly for me. Perhaps it was just the perfect storm of mods I had at the time.

I believe so, but could be wrong. I couldn't get it to work and had zeroed in on the smali file that needed to be changed. I believe I did a checksum comparison and found them to be different.
Without prime's mod I could only tether up to my 3 GB bucket or had to do a dirty hack to hostapd for it to allow wireless clients to connect. It would default to 0 clients for some reason. Maybe I had a weird storm of mods that broke it.

The way you worded that, you describe Prime's mod as using IPv6 to work around Tmo's tether limit, but it doesn't, it must use IPv4 to "mask" it.
When I change the APN back to IPv6, my hotspot enables but does not work whatsoever, nothing loads on my laptop, it'll connect and obtain an IP but no traffic is sent nor received over the phone's data. Can't remember if it's suppose to be like that or not, but IPv4 works, IPv6 does not with hotspot, but data stills work either way on the phone itself. I'll post over in Prime's thread about this.
BTW, WiFi Tether Router borked for me two about three weeks ago, a few days after Prime's mod came up, luckily. Been using it ever since. :highfive:

When I change the APN back to IPv6, my hotspot enables but does not work whatsoever, nothing loads on my laptop, it'll connect and obtain an IP but no traffic is sent nor received over the phone's data. Can't remember if it's suppose to be like that or not, but IPv4 works, IPv6 does not with hotspot, but data stills work either way on the phone itself. I'll post over in Prime's thread about this.
BTW, WiFi Tether Router borked for me two about three weeks ago, a few days after Prime's mod came up, luckily. Been using it ever since. :highfive:

It has been a while so I forgot how Prime and WiFi Tether Router worked. The stock tether app, with the stock tethering APN uses IPV6, but you're right, Prime's mod uses IPV4 with the mobile data APN.
WiFi Tether Router implements its own DHCP server, iptables and hostapd configuration. Something in the way it does things makes the traffic look different from the stock tether traffic, so T-Mobile is able to block it.

This is remarkable to me. It SHOULD look completely the same with the exception of user-agent (which is easy to spoof).
I've been using EasyTether (the USB version) and they have yet to figure out how to block that AFAICT.

That was my assumption, but I don't see why it would be different either.
I just tried WiFi Tether Router on my phone and it worked just as well as it had in the past. I did some tcpdumps and the traffic looks the same on both. My guess then would be the users that are getting throttled or blocked are doing things that are CLEARLY not mobile phone traffic.
Another user did 32 GB of Xbox Live traffic while using the PrimeTether mod and was throttled. Surprise? No.
Those getting blocked or throttled are probably abusing the system.

Wifi tether router works for me on my tmobile S5.
