I seem to be cutting out on wifi calls

A couple friends have complained I cut out while on wifi calling. I don't notice them dropping. Any ideas?
I'm on Darkside 2.5.1, my network hardware is...connected to Linksys E3000 operating as an AP, upstream is a Linksys E4200, Cox is my ISP 25 Meg circuit. Ping times over the same wifi connection are always under 35ms.

I had that happen when I would walk to far away from the Router...is this happening when your standing close to it? Seems odd for sure.
Kinda off topic but have u noticed voice lag when using wifi calling?
I have stopped using wifi calling as the voice lag is disturbing compared to using the cell network which has no voice lag issues.. Makes zero sense to me.

I havent noticed any lag, just apparently cutting out. Im not far away from my router either...full signal. Im going to try an experiment and connect to the main router upstairs instead of my AP downstairs...maybe something in that connection is causing it.

I've had problems when using a bluetooth headset while on wifi calling. This happens on stock and on both roms I've tried. I don't have trouble with wifi calling as long as I stay off of the headset.

I've experienced the same issue but always blamed it on my Internet connection.

Its not the internet connection, for some reason the current ROMS dont play well with wifi sharing, or should I say Wifi and Data connection. I was running Juggernaut5.0 when I noticed that the wifi would stop working after 15mins. I also used All Share and it at the same time wifi calling would stop working. I also noticed when I woke the phone from sleep state, the 4g symbol would return and then I would loose wifi calling. The 4g would disappear and only wifi would show but calling still wouldnt connect. I returned to my nandroid of the stock rooted and I havent had an issue since. Wifi calling will always work along with allshare. One thing that I did notice is that airplane mode would help keep the consistency across the board. IDK
P.S. my gateway is in my bedroom where I mainly use my phone. Most of the time its in arms reach, sits right next to my xbox

Well I set my phone to connect to my main router upstairs instead of the AP downstairs. It seems to have helped a bit. Friends reported far less cut outs. Only a couple in a 20 min call.
Perhaps there are others with similar set up having similar issues this may help.

{REQUEST} T-Mobile Wifi Calling

Is there an app that I can download somewhere or is this something that someone could throw together for use with the Nexus?
I work right outside of Tmobile service area. I usually get about a bar or 2, on a good day. I rarely ever use the phone, didnt even realize these things could make calls anymore!
Anywho, I had an Amaze which had wifi calling and the call quality would be crystal clear over wifi calling and did wonders for saving battery.
Any help would be much appreciated!

I was disappointed to find out also that it was unavailable on the GNex and from what I read on it it's near impossible to port it over.
An alternative may be a combo of Google Voice & Groove IP, I use that combo on my Moto Xoom Tablet and it work fine.

OK so maybe I don't understand how groove IP works....but when I make a call over wifi the phone is still looking for a mobile signal. While I was in the call the phone showed one bar or service. So at that point isn't the lack of cellular signal still going to eat away at my battery?
I suppose grove is made more for a situation where you have no service at all? I tried putting the phone in airplane mode and make a call that way which does work.....but then your screwed with the texts......ugh....FML! Ha.

Heres a screenshot showing one bar even when I am on wifi within a call over groove. If i remember correctly when wifi calling was being used on the Amaze, the mobile signal would be turned off completely.

Hopefully with the One S out now we'll be able to get wifi calling? Anyone heard any progress on that?

Download "Viber". This is an OTA/WIFI calling app. Also dl "phone + WIFI on/off" widget. Both available in the market.
Sent from my Galaxy Nexus using XDA

Viber requires both parties to have the app installed if I'm not mistaken. I think that is unrealistic.

wifi was never crystal clear on the t989
that is why we left tmobile it would cut out swell groove should work fine why dont you disable data then turn wifi on and link up tjat way it will work like a charm i promise

I'm not sure I follow you too well. I'm still a noob. Would you care to elaborate on that.

Try the Vonage app. You can make calls over Wifi and data the other person does not need to have the Vonage app to receive calls. It's only good for making outbound calls on Wifi or data. (Doesn't count against mins either) If you receive a call it goes through regular cell service and bucket of mins. You can make calls to any where in the US for free. Right now you can use up to 3,000 mins a month for free to make calls. (Promo with no end date set)

But in order to receive calls the radio would have to be left on or else they will go directly to voicemail right. Which means I would have to leave the radio on.....so once again I would have low reception leading to eating up better. But anyways I think you maybe mistaken....vonage app says the other person must have the app. FML! Ha.

WiFi/data issues

How's it going everyone. Just left sprint for T-Mobile. Even with the problems I'm having its still better than sprint crappy network. Anyways. For some reason no matter what ROM I'm on I'm having issues where the WiFi will turn off it will go to 4g than WiFi will randomly turn back on. Or I'll have great service than randomly I'll see an E near my signal bars and it slows down for a good 5 minutes. Any idea what may be causing the problem?

Make sure WiFi calling is disabled. Then go into Mobile Networks and change Network mode to WCDMA Only. See if that helps.

Well if you are getting the E, that's Tmobile's network for ya. It is quite spotty. I get the same thing and goes back to 4G soon after. One of my main gripes with Tmobile.
If you do what DocHoliday said, it won't work at all. Just won't have any signal at all. If you leave it to auto, you will at least get the EDGE network.
Did this do the same thing with your old phone? If not, not sure what the deal would be besides weak radio maybe.

Try using the Llama app to force wifi on and disable the radios when around specific locations?
That's a workaround though...

Its worth a shot. I had issues with staying on 4G when I first got the phone. That fixed it for me.
Spotty service depends upon your area imo. Sounds more like a network issue to me. Could be a side effect from all the refarming work they're doing on the network. Its a nationwide project so it can hapoen anywhere.
@op
If you turn off WiFi does it work as it should? If so check that WiFi calling isn't enabled and set to WiFi preferred. If it is turn it off and test, then if fixed turn it back on and try Cellular preferred.

Dude I had that same issue until I flashed lh2 roms. Havent had that issue with lh2 roms at all.. try stocked up or wildchilds xquizit.

For what it's worth, I had this issue yesterday out of the blue. Nearly every time I would unlock my phone, wifi would be disconnected and I'd see the 4G icon. After unlocking the phone, a few seconds later it would connect up to wifi again. And yes, this is even with wifi set to always on in the advanced settings.
I realize there could be multiple causes for this symptom, but the fix for me was simply forget the wifi network and connect up to it again and the issue disappeared since then. Hasn't happened today yet either.

Strange issue with wifi

Stock sgn2 in the upper right hand corner I have the LTE icon and wifi at the same time. Am I missing something here?

Yes,I noticed it with mine too..but i think it will still use Wi-fi network when you browse(i tested it with speedtest app,it used Wi-fi)

It seemed to keep saying couldnt connect wifi using mobile data on Att messaging app, it didnt seem to be using the data connection for anything else and was only sending/receiving on wifi

I noticed mine seeming to drop from wifi when the screen is off for a while, even though I have it set to leave wifi always on.
When I would turn the screen on, it would show LTE, then LTE and wifi, then just wifi and give me the message that it connected to wifi. I also noticed the icon for the preloaded AT&T Smart Wi-fi. My assumption is that this app is causing me to drop from wifi when it shouldn't be.
I disabled AT&T Smart Wi-Fi and haven't had the problem so far today.

Jrockttu, thanks for your suggestion, it was driving me nuts. I've just picked up my Note II yesterday and UNFORTUNATELY I enabled the AT&T Smart WiFi app (and then forgot about it, of course). After that I couldn't stay connected to WiFi, the WiFi radio kept cycling on and off, it was maddening. Luckily I found this post, and after disabling the stupid app, now I can stay connected to WiFi.

Note II drops WIFI Calling??

Hey I'm a 1st to T-Mobile i'm testing it out before I switch all my lines from Verizon. The question I have is that both the Note II and the GS3 that I have seem to drop the Wifi calling feature randomly. I thought at 1st it may have been some sort of power saving option but it seems to happen in frequently. (Doesnt matter if I'm close to the Router or not)
Is this common? Or am I the only one that has had this happen?
Thanks for any input!

I'm not sure what you mean by turning the App off? When turning the WIFI calling app off does that not mean you are unable to use the feature?? LOL- I have to have this as I have zero reception at my home.
Thanks for letting me know!

@ scoob go to setting, more setting, deselect the wifi calling app and it should work for you my coverage at my place is between 0 and 1 bar so this should help

mine goes on and off on both my new note 2 and my wife's new galaxy s3. really aggravating. worse on my phone, when in wifi calling, it only answered calls like 1 out of every 10 times, otherwise they went to voicemail. I took the sim out of mine, then put it back in and pushed it in and out and in the holder a few times and now it seems to receive calls in wifi mode but still always in and out and error to connect and such.

My experience with Wifi-Calling has been nothing but troublesome. It's really not reliable at all, sometimes calls comes through sometimes don't.. and when it does come through I can hear the caller but caller cannot hear me. This is quite common problem with wifi-calling and i given up.
If you get even a 1bar of reception near by the window, I suggest calling T-Mobile and getting their Cel-Fi device (Free of charge but has to return when you leave T-Mobile). 1~2 bar by the window will give you full 4bar reception throughout the house on 4G. Only requirement is that you must be living in single house, can't ship out to house that are connected by or close by. I live in townhouse and I just told them I live in single house and got the device in 3 days. =)

Wi-Fi calling is a disaster. For me, incoming audio drops constantly, but the party I am calling can hear me fine. On other occasions, the call will just randomly drop. Came from a Sensation where Wi-Fi calling was perfect. There does not seem to be any resolution... I have spent hours talking to tech support and they have replaced the device with no improvement. I have also had my ISP out and they have verified that my connection is fine. I have even changed the router out... same issues.

With my wifi calling, as soon as I turn kt kn my bars at home would drop where I would hardly get any service. As soon as I turn wifi calling off I magically get bars. So I leave it off and now I get bars pretty much everywhere I go....almost

With wifi calling on, it's suppose to drop signal bars to nothing. You have to go by the wifi bars instead.

Wifi also greatly depends on your network conditions. Cause I have the same problem but it doesnt happen to me that often after some tweaking.

Wifi Issue
I have that problem quite a bit but the signal strength on my router is good. Yesterday i had my internet company reset the cable modem and my wifi problems have decreased a lot but it is still happing. It has to deal with the wifi certificate problems on the Note 2 (Samsung). It is the same problem that I had on the GS3.
Oh well

Uhh, that's the point of wifi calling, to make calls over WiFi and disable your cellular radio. If you turn on Wifi Calling, you should get a blue phone icon on the top left and your "bars" should drop to nothing as your phone turns off the cellular radio. You can still make/recieve calls/sms/mms.
I've been getting an ER01 error lately with invalid certificate, but it seems to be a T-Mobile backend problem? It happens, about 10% of the time and only on my school's network (I have a feeling, it might have to do with the sign in process there).Otherwise, it works well at my apartment.

i get that certificate problem at my house, not too much anymore, but I still see it. and the wifi calling does drop in and out at various times. not a huge deal for me, but the average person wouldn't deal with that.

I've been noticing more & more problems with my service in the last two months. I called T-Mobile to fix it and whatever they did seemed to only help a little. I get times where I get frequent ER01 errors with WiFi & duplicated text messages (same text message gets received by my phone 2-3 times) for an hour or two. I used to also get errors sending texts around that time, but that appears to have gotten better.
Someone else mentioned Uverse, and my WiFi calling problems are at home & work, both of which have AT&T for internet... When I switched from their DSL to Uverse I expected less problems, but got more.

Seems to be a problem that a lot of people are experiencing. Just did a quick Google search and some indication points to a possible T-Mobile back-end problem. I wonder if i call up T-Mobile and ask for wifi calling to be explicitly added to my plan if that'll change anything.
