[Q]WiFi calling, issues every night

OK so I've searched this a lot and really didn't want to make a thread but it's driving me crazy. My WiFi calling is rock solid all day and then from 6, 7, or 8pm till around midnight it constantly drops and comes back. I've gotten the red invalid certificate thing and reg99 (or 09). Whichever one IS NOT the 911 one, my address is up to date.
Is it network traffic at night or what?? My house has 0 cell coverage so WiFi calling is important. It's getting really frustrating having it drop and come back every few minutes.
I'm on frostyjb, but I think that's probably irrelevant. From the tmo forums it sounds like these issues have been around for a year or so. Does anyone have any advice, or tips or tricks?
Thanks.

Most likely its due to increased traffic on your isp. They probably don't have a very good uplink making it easier to run into these type problems.
That's my best guess seeing as it always happens at the times known for heaviest traffic.

I've been using Wi-Fi calling since it was first released on Blackberry, haven't noticed a specific time when it fails, seems to be random.
I will say each phone has had its own "quirks". the HTC Sensation wouldn't like to re-register to Wi-Fi Calling until it established a mobile network connection, pretty annoying
but I will say without a doubt this is the worst phone for Wi-Fi calling I've had to date. Samsung really needs to fix it. generally my issues include:
- One way audio (10% of the time, or more)
- "Digitized" voice calls
- Red certificate error
- WiFi calling just shuts down, in the menus it says "enabling calling", typically takes 3 - 4 minutes to come back up
- Dropped calls, typically due to above
- Wi-Fi signal drops, I have my router on my desk and I can watch the Wi-Fi connection bar randomly drop to 1 / 2 bars for a few mins then go back up, why? no idea. Doesn't happen on my Tab 10.1 or other devices
OVerall its an awesome phone if you have signal, but the wi-fi calling is trash

I am in the same situation and I assumed it was just my phone losing wifi coverage at least now I know im not crazy. I would assume its just something to do with the date turnover because it seems to happen at around 9pm for me which is midnight on the east coast.

I had the same problem, So first i would try updating the firmware for your router. If that doesnt work, Check to see if your router is a single or dual band. I had a single band Linksys,which gave me terrible reception, so I upgraded to a dual band and the problem is much better now.

I have a dual band router but I don't use 5g because its range is pretty bad. It has drop outs when I go in the bathroom and that's a big time use for me lol.
When wifi calling drops I still have full wifi signal and the Internet works. It really sucks because I have 0 bars in my house. I've seen 2 bars but as soon as I touch the phone I get the do not enter circle.
I'll try updating the fw to see if it helps tonight. I've read something about the security used can mess with it? I just think it's weird that its usually at a specific time. Ie the security settings is a cop out.

Yeah, I read that having mac filtering enabled or a hidden ssid can cause issues too. Check that out while youre updating your firmware. Edit: I also tried a factory reset, which you might want to look into. Also, try testing other kernals/modems!. Thats all I got for ya though. Best of luck

I blame tmo...
I ran a speedtest immediately to see if anything was suspicious. I still need to play with the router

I plan on flashing FrostyJB and Xquizit tomorrow. I'll let you know if I can replicate the issue on either rom.

Is it possible that having Comcast voice is somehow screwing up the internet? Like if tmo and Comcast are sending similar packets??

Not Only Me
Its nice to know I'm not the only one with this problem.
I updated the firmware on the phone, bought a new router; still have the problem... The little blue phone icon comes and goes, turns red. Seems to do what ever it feels like doing.
Will follow the thread for a solution.
Thanks to all for the effort.:good:

The last few nights have been a little better. With it usually coming back after leaving the phone on for a minute or so but it's still dropping every night. It really sucks for me because my house has 0 bars.

Im also having same problem where I live. I have no bars. I use Grove ip to make calls when wifi calling dosent work but I need wifi calling to send and receive mms thats the only down fall to grove ip

I have been having the same issues too. Not necesarilly at specific times, pretty much all times of the day. Specifically random disconnects in the wifi calling (losing the symbol all together, then it comes back spontaniously whenever it wants). Probably the most irriating is the one way audio which has occured EVERY PHONE CALL RECIEVED OR PLACED for the 1st time after about 10 minutes of inactivity (meaning everytime I make or recieve a call the one way audio happens and I have to call back or the other party must blah blah blah). And digitized calling is almost a guarantee on every call. All is well with router and wifi settings, no data/cell service inside the building at all.
This is my second GSIII (this is a refurb POS they sent me after my new one had a screen crack). After 2 week back and fourth they are replacing it Ill have a new one tomorrow (prob another dumb refurb) and Ill let you all know if the issue is resolved. My first GSIII (the brand new one I purchased when they came out) had no issues like this at all. Hopefully they replacement will shed light.

No one can hear me when I use it (8 of 10 times). I also never hear a ring. People are just on the line all the sudden. Sooooo frustrating.
Does everyone have this problem? If not maybe it's a router setting? Would be interesting to know.

I've had this. I was calling someone on Verizon and after some silence they picked up. Also if I call my phone from my Comcast landline there's no indication it's going through on the landline but my phone rings. I think these issues have been around awhile and tmo hasn't done anything. I wonder how we can get them to actually look into it...

Flood the support forums maybe?

Yeah I think we need to bring this to t-mobile attention because most of all that i've read on here, i'm experiencing the same. I've tried different router settings as well but, nothing has worked.

I tried dmz and opening ports that tmo has on their forums. Nothing worked.

I love this thing!

I've been troubleshooting as well. Looking into my router settings, I had my channel set to 11. I changed it to 1 and so far so good. I'll update as I go.
I'm just sayin!

[Q] [RADIO ISSUE] SGN GSM slow at reconnecting to network

Wondering if anyone has the same issue: after losing the network signal (in the underground garage), it takes up to 2 minutes to reconnect when I exit the garage... Very embarassing, I checked on my old LG Optimus 2X and ZTE Blade and reconnecting takes 10 sec max.... I am on the latest CM10.1, using the latest radio, I remember the problem existed in stock as well. Thanks...

Guess I am the only one having this issue...

No, you're not the only one. And not the first person to post about it either.
In my case it's taken far more than two minutes. As you said, it's easily repeatable. Just go into an area with no signal like an underground garage. I've seen close to ten minutes and I just gave up and cycled airplane mode to fix it.
It's really surprising how much basic functionality doesn't work right on Nexus devices.

Weak Wi-Fi signal

Since I first used the phone I noticed that it doesn't perform very well when it comes to picking up Wi-Fi signals. For example, the access point in my house is about 15 feet from the bathroom, blocked only partially by a column corner; with all my previous phone I'd get maybe 2 or 3 bars (at least), but with my P6 I can barely get one, if it connects at all. Everyone else (but me) seems to be able to connect to a given access point from the same spot. Aditionally, when connected to a Wi-Fi network (very close access point, of course), the symbol seems to very briefly dissapear and reapear again, I'm talking about miliseconds, but it happens somewhat often.
I've read something about radio bands, but I'm not really familiar with these stuff.
Is the P6 Wi-Fi antenna particularly weak or is it just my device?
I'm on B512, coming from B508, both firmwares perform equally bad with Wi-Fi.

i think it is the way the p6 is build up hardware sides..i have often the same issue..

Throwing my phone across the room.. Help

I have had this phone a total of 3 days. I am coming from a iPhone 6 and previously had a Galaxy s4 and 5 before this.
This phone is annoying me. Its sad because its so beautiful and if it functioned normally, we wouldn't have a problem. Sometimes I want to throw this thing across the room.
Someone please help me with these issues. I rely on wifi and wifi calling.
Issue 1: When I am home and connected to wifi and wifi calling, my messages and alerts do not come to me when I leave the phone down for a while and it goes to sleep. I will pick my phone up and suddenly I will get all my text messages and alerts. Wifi sleeping is on NEVER already. My iPhone never had this issue, nor did the previous samsung phones.
Issue 2: When I leave my house, the internet connection does not work all the time. Today I left my house and drove somewhere and needed to use my gps. I had full LTE service, and it was telling me I am not connected. This also happened with my apps that also did not work because it was acting as if I was not connected. Issue was fixed with a phone restart. I do not want to restart my phone everytime I leave wifi.
Issue 3: MMS does not receive or send on wifi. I had this issue with prior galaxy, but I am shocked this still has not been adressed.
I also keep LTE voice OFF because like with other phones that have VOLTE, for some reason it just does not work that well. I am in NYC so its not a reception thing.
Those are my MAIN issues and would like some help with them.
The only other thing apple has samsung beat on is that with headphones connected, the apple blows away the samsung in terms of volume and sound quality. Its sad because I have expensive headphones that I would love to use all the time, so I guess I will have to buy an iPod touch when and if I sell the iPhone
Also the screen is very sensitive. I see myself accidentally opening apps when all I want to do is swipe across my menu screens. Not to mention it keeps telling me that hangouts stopped working, when I have it disabled already!
I am stock btw. Latest version, and battery has been good surprisingly. I do not want to root
Anyway, thanks everyone and please help and address the top two issues

Turning Wifi calling off will help drastically with those issues have you tried it without yet?

As I said, I rely on wifi and wifi calling. I live in a basement apartment with zero service. Who would buy a phone that is almost 1000 dollars, and have to turn off services you pay for to make it work the right way? There is no way wifi could be turned off while I am home

Try doing a factory wipe, that usually solves issues like that.

Factory reset a brand new phone? Sweet.

Contact your carrier and request a signal booster, no charge to you. Then you can rely on data instead of wifi. Also start a complaint ticket for the phone, after a while they will send you to tmobile store and replace phone. Maybe it's buggy, maybe it's not.
But if you really have to throw it I'll come over and catch it.
Our phones must be total opposites because this is the best Samsung phone I have had, this makes # 4, Captivate, GS2, SG4 and now the S6e.
But you never know, visit the Tmobile store, remember that you have 14 days to be totally satisfied, that means replacement with another NEW phone if necessary.
Pp.

I know your pain. The fact that you're on t-mobile for wifi calling and this garbage device just not cutting it huh. I had almost all flagship samsung phone and this one right here is the most frustrating and expensive one of all. This device out of box is just terrible. Memory management, wifi issues, battery leak, FC left and right is just what I experience. Honestly this phone is making me understand why apple is better. Not because the people are stupid. But because they don't deal with half of the broken process we do here in Android. Yea I agree apple is like 2 years behind android but wtf. Now with Jump on demand I am thinking to make the switch to Apple or continue to toss my phone on the table when upset that the device once again is not responding. But lesson learned. Not jumping on new Android devices on release. This phone is a testament why.

Actually the phone works great right now. Maybe it needed a few days to become normal. Battery life is better then my iPhone 6. The text issue seems to ha e gone away. I still from time to time have the issue of leaving my house from WiFi and the phone acting like it has no connection, which requires a restart. I wonder what is causing that. Overall I'm happy with this device.

I can relate to you on T-Mobile LTE, and the screen. Although the reason the accidental app opening while swiping I think was happening because my hand was touching the side of the edge screen. Hold the phone differently or put a case on it and will notice this issue is decreased or gone completely.
There is still a screen issue with this phone and I've noticed it when typing out a fast message. Touch inputs do not register sometimes. That issue has some what been resolved with the case and my hand not being on the edge, but the issue is still there. My Note 3's screen is so much better in regards to accuracy and sensitivity.
For a $1000 phone, this thing should be close to flawless but it does have quite a few flaws, especially with Touchwiz and crappy lollipop. My main issue with TW is the way it manages memory. I just wanna throw this phone at the wall and stomp on it. I'll be in Chrome, go to reply to a text and make a note in Google keep, or whatever, come back to Chrome and it reloading the page I was just viewing a minute ago. So damn frustrating.
I haven't really been on XDA as much as I have in the past, but what ROMs can we flash for this phone because from the looks of it, the dev forum is a ghost town.
In regards to T-Mobile's crud network, just switch your phone into airplane mode, then off, a lot faster than rebooting the phone. This issue I've noticed only happens with LTE, what I do is just go to network settings and switch to WCDMA ONLY, which turns off LTE and connects to HSPA only, which is more reliable and FASTER in my area. Hope I helped someone out there cause I just typed this all on my S6 Edge.
Don't get me wrong, I love this damn phone and wouldn't trade it for any other phone, but better believe I'm gonna swap it out for the Note 5.

This phone has fantastic hardware and the worst software of any phone I've ever owned. I can make compressed twrp backups in like 10 minutes. The screen is the prettiest I've ever seen. The fingerprint reader is very good. The camera is damned fantastic. The software is a pile of dog ****. Samsung should be ashamed. They should be ashamed because I just bought a heavily discounted Fire Phone and loading CM11 on it because I just can't take this crappy phone any longer. I'll check back in on the next update to see if things have improved. Until then I'll be using a phone that cost around 4.5 times less and will somehow perform better.

Funny thing is I have to reboot it if that problem ever happens. Airplane mode doesn't reset it. Weird

Going to have to disagree politely with the OP on headphone output quality. I too have an iPhone 6 and while yes, it has more volume, they both have enough volume to drive proper headphones and I find the output on the S6 to be extremely clean and more lively than the iPhone 6 output. Check GSMArena's review and notice they say it has the cleanest output of any smartphone they've tested thanks to the onboard Wolfson DAC. To each their own with sound quality, but I find the S6 to be extremely good, especially after the 5.1.1 update.

Nonsense! That sort of behavior is not allowed here!

Yeah nothing wrong with disagreeing. In my opinion it's much lower then the iPhone 6. It went from being fun to listen to music on my vmoda m100s to me wishing I could make it louder on my gs6. Also affected the quality in my car via Bluetooth. Much lower output. I guess every one has their preference

WiFi drops

I'm away at the moment, but I've come across a problem that my partners Galaxy S7 is not even phased by.
weak WiFi signal.
where I'm staying, my partners grandparents have basic Internet, just phone line BT so it's not brilliant in the first place (at least, not when your used to 150+mbps). And is just naff at WiFi signal. I'm on the same floor as it, not very far from it, and it's just weak.
But my problem is that my phone just gives up when I try to do anything "demanding" like a quick video or download a picture from Google drive. the phone just cuts off the WiFi. and I have no mobile signal whatsoever, so that isn't even an option whilst I'm in this house.
I know the m8 had similar issues on it, to the point where I could not even get back onto WiFi until I changed the SSID to something else.
I usually have no issues at home, so it's only really just a problem that's come to the surface. what I don't get is why I'm having these problems and my partners s7 keeps on going.
guessing it's just typical HTC quirk?

I love my HTC 10 but the WiFi on this phone is just plain weak... I'm upstairs and my almost 3 year old lg3 can do YouTube videos no problem, but my HTC 10 can't even connect.. Was hoping it was a software problem,but 7.0 update didn't fix it...I go downstairs and the HTC 10 works fine...all phones have problems... What to do!
