[Q] WiFi Causes Signal Loss - T-Mobile myTouch 4G Slide

This just started happening within the last week.
My phone is rooted.
It seems that when I have WiFi turned on I have a complete loss of 4G/3G/2G/G RF. If I turn WiFi off, then the phone signal comes back. This wouldn't bother me that much if I could send texts over WiFi with no normal phone signal, but everytime I try to send a text over WiFi it fails to send. Anyone else experience this issue?
Thanks

With wifi calling it purposefully turns off your mobile data so it doesn't use any of your minutes/data. You can go into wifi calling and select preferences and turn it to cellular connection preferred - that way your phone will still use your signal whenever it can, but keep in mind you'll use a lot more data and your battery won't last as long. I do have texts fail from time to time on wifi calling but it hasn't been too bad recently. If you don't have a good wifi signal then just turn off wifi calling.

Thanks for the info!
So why would the texts keep failing? I will even try to keep re-sending the text and still they will fail. Is there a specific port on the router that needs to be open for better optimization?

[Q] Wifi Calling Issues

I am having an issue with wifi calling on a my One S. For background info I am using a completely stock rom, I am rooted and I have only removed non t-mobile related apps like where's my water and movie editor.
My issue is this, I have wifi calling disabled in settings and yet every time I connect to a wifi hotspot whether at home or anywhere else it attempts to use wifi calling. when it does this I lose all cellular signal and can no longer receive/send calls and texts. I have tried factory resetting the phone as well as calling t-mobile. I was on the phone with them for about 2 hours or so last night and still no fix. Just curious as to what I should do to fix this issue or would it be easier to just get an exchange on the phone.
I have also tried setting up wifi calling but at the same time I would prefer to use my phone connection for calls due to irregularity in hotspots i connect to, hence the reason I have it disabled altogether.
Any help is appreciated
Try setting wifi calling to cellular preferred

Yeah that doesnt seem to help either. I am just about to take phone back and try another. I hate not being able to use my phone my WiFi. No matter what setting I use I can't seem to send or receive any calls or texts. The instant my WiFi connects I get a big X on my cell signal indicator.

This problem is stupid but is easy to fix. Whenever you finished using wifi calling feature, the phone's radio is auto-turn off. That why you can't call or send text message. Open dialer pad, type *#*#4636#*#* ==> phone information => turn on radio. I believe this is a bug because i never have this problem before when i used htc sensation,mytouch 4g

Wifi Calling/SMS over wifi --issues and solution.

I have had a crazy time both with wifi calling remaining connected (suffered sudden drops), and further SMS over wifi seemed spotty at best.
Part of this was caused by either a bad SIM card, or deletions of stock apps and/or services...which now have been fixed.
At the moment everything is working fine. Don't know if this will affect anyone, but I thought I would just add to the library of knowledge.
First, once I got wifi-calling working (meaning the status bar icon was no longer red), I started to read the log files and realized that every time the wifi was reset, wifi calling would not consistently restart.
What I have realized is that wifi-calling and SMS are dependent on TMOs mobile network via wifi. However, any internet connection is simply that...and any apps you have like FB or Google Voice will work with that wifi internet connection. Conversely,the TMO wifi-calling service/app either connects on a different layer (such as the IP layer) or uses some unusual node-based connection to traverse the 802.11 frequency, over your ISP's and other networks to arrive at the TMO servers which then are linked into the mobile network. You can see this by downloading an app that triangulates and provides tower locations nearby or gives you other mobile network data (i.e., CID, etc)... That data is either not decipherable by the app trying to get this data, or one gets unusual info when compared to non-wifi calling. Bottom line is that there are two separate signals being carried by the wifi: "data" and "mobile wifi calling" and they are completely different.
Another example of proof: if you are having difficulty with SMS using your wifi internet connection, try sending the SMS via Google Voice. If you have an internet connection, it will go through immediately. But regular SMS has problems if wifi-calling is not working correctly.
And one of the biggest culprits of this is wifi fixer or other similar wifi connection apps. Although it's only a guess, the "scan" these apps do are likely a simple ping to determine status of the DATA connection.
I shut off wifi fixer (but left it as a widget to use as needed), and I have perfect wifi calling and SMS.
Whatever criteria wifi fixer apps use when deciding to reset or reassociate the wifi connection is not reflective of the integrity of your connection using wifi calling. In fact wifi calling may partially interfere with your data connection which will typically trigger a reset by wifi fixer.
From now on, if I am planning on simply surfing the web and my wifi signal is less than optimum, I will turn on wifi fixer. Otherwise it just tears down wifi calling connection.
Hope this is of use.

Thanks for sharing your experience. I have an issue where over time Wifi calling disconnects even though wifi is still working. I have to re-toggle wifi to get Wifi calling back. It's very annoying.
Talk to NRGZ28... I think Energy ROM had a fix for that I'm the Amaze 4G Energy ROM

Although there have been occasional exceptions, it's unusual for a wifi call on my H1s to last longer than about a minute before dropping off/disconnecting. When this happens, the call time counter changes back to say "Dialing." Of course, there is no dialing, just dead silence. There are no other signs of a problem, no error messages, no indicator icons, etc. On the same wifi network I can make long uninterrupted calls with our older MyTouch 4G - no issues at all with wifi calling.
I'm running unrooted, locked, stock ROM (for now). I don't think I've removed any apps and I think the only wifi-related app I've used is Wifi Analyzer. Could you offer suggests on how to debug this? The firmware update didn't give any improvements. Should I ask Tmo to provide a new SIM card?
Thanks -

Well the first thing I would suggest is a factory reset. This being the most simple option given your phone is not rooted and on stock. The strange part of this is the "Dialing" instead of the normal keypad (which typically reverts when a call is disconnected).
As far as a SIM card, do you ever get any SIM card errors? Like "ER05" or "REV99"?
These are typically the errors of faulty cards or a bad wifi signal. Check out an app called Network Signal Info....it will tell you the strength of the wifi signal compared to the mobile network (although its not always reliable).
Let me know what a factory reset does. All of your apps will be restored by google (and their are apps to modify this restore as well).

Didn't reset yet, want to test a little more.
I've never gotten a SIM card error. The unexpected "Dialing" with the End Call button still showing is the only indication something is off.
Tonight I ran a few tests calling between our 2 Android phones in the same room, same wifi. 3 calls 1S to MT4G: 2 were perfect and lasted several minutes, while the middle call disconnected after less than a minute. 3 calls MT4G to 1S: all 3 went directly to voicemail, the 1S didn't even ring. Now I recall that's been a complaint before - that calls to me go straight to voicemail when I've been on wifi calling.

Are you sure wifi-calling is on? Do you have the blue icon in the status bar?
Sometimes this isn't on, even though wifi is on and you are making a call.. Not sure if that is intentional or not.
Just in case... The switch is in settings> more (under wireless and network buttons)

Yep, it's on.
Just to be clear, the H1S has received calls when wifi calling is on, it's just sometimes that they go directly to vm. For example, as I'm typing the phone just received a wifi call and is handling it fine, hasn't dropped after 3 minutes.
NO CONSISTENCY, BUT USUALLY DOESN'T WORK.
A factory reset did not fix the problem.

Radio signal disconnects

I've been explaining these 2 scenarios:
1. Wifi and edge are on, and data stops working, whatsapp messages don't go through, i have do disconnect wifi and data is restored
2. wifi is off, edge is on, SMS's don't go through, and I can't make any calls saying the network is unavailable.
In both situations I have a full signal bar.
Using faux kernel. Has anyone else encountered these issues? factory reset doesn't help.

[Q] No Wifi during Calls?

So, whenever I made a call on my N5, the Wifi gets turned off and it switches into 3G/HSPA+ mode (no LTE). When I end the call, it will connect to LTE and then enable Wireless again and connect like normal. This is on T-Mobile if that means anything.
Is this suppose to happen? Is there a way to prevent it from disabling Wifi during a call?
EDIT: The issue was with Tasker, since I use Cell Towers to tigger Wifi, and I guess calls uses different towers.
Anything? Even when receiving a call, before the call actually "comes through" the Wifi will be turned off; THEN the call comes through.
I just tried calling my ATT phone in a good LTE area with good WIFI. It did not drop wifi. I'm stock non-rooted 4.4.2.
There is a setting in the wifi page which prevents the phone from connecting to poor wifi. Is it possible that you're in a borderline poor wifi area and when a call is received your wifi drops just below that threshold and phone then falls back on 3G/LTE ? I noticed my phone at home when I go far from my AP I get 1 bar on the wifi but the phone says it is connected. But then wehn I try to access a web page, the phone would drop wifi and connect to 3G. I don't have LTE at home so I can't say if it would've connected to LTE straight away after wifi drop off

Question Wifi calling problem

Hi.
I get wifi calling working fine on my phone, but it just disappears and stops working after a few hours. Rebooting makes it work again.
Anyone else have this problem?

Are you sure it's failing and what do you mean 'stops working'?
Do you try to place a call and it fails because WiFi calling is broken?
Or are you just watching the carrier name change off of WiFi calling? Because your phone will move off of WiFi calling if the signal strength is low enough and the strength of the cellular signal is higher.
The preference switch just dictates which to favor first over the other, it doesn't lock you to WiFi calling only.
Try walking closer to an access point and checking if WiFi calling comes back, that's what it does for me I move from outside with a weak WiFi signal to inside with a strong signal.
If that's the case then you'll need more access points in your house.

Where I am right now there is no cellular (offshore). I can also recreate the problem if I turn flight mode on and off. After I do that I can't do wifi call (the icon/text is gone and calls and texts are not working anymore). Kinda weird behavior tbh. It might be the wifi, but it was stable on my last phone. I can wait till I get home and try that wifi, but it's only here at work I need it

Try disabling MAC address randomization for the access point you are on, it defaults to enabled. It can cause issues if the DHCP lease time is low and your phone gets on and off the network, making it show up as a new device each time.
If it still is having issues then it might just be the network, a grocery store near me has filters and when you get on their guest WiFi you can place a call for a couple seconds before it kills the connection.

Disabling the MAC address randomization did the trick. Been on and stable since I turned it off. Thanks again
A new problem have emerged in this same topic.
Using the same phone, same sim, same wifi, same settings (disabled mac address randomization) the wifi calling won't activate at all now. Any idea what I can do to trouble shoot? Wifi calling is turned on and set to preffered.
