Radio signal disconnects - Nexus 5 Q&A, Help & Troubleshooting

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] WiFi Causes Signal Loss

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?

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.

[Q] WiFi and cell signal randomly cut out

Having a problem with my One. During normal use (screen on or sleep) both the WiFi connection and cell signal will be dropped. Internet connection is interrupted and SMS fail to send. When I pull down to the quick settings menu, the WiFi icon and Cell Signal icon are both orange. I know orange usually means that there's trouble connecting to Google services, but this doesn't explain the lack of cell connection. In order to fix it, I have to manually toggle both the signal and WiFi.
I'm on 38R, stock kernel. Using the phone on Rogers Wireless in Canada.

[Q] No SMS while on wifi, can't switch from wifi to cellular

My Nexus 5 is running Android 5.0.1 (Lollipop). Unlocked, not rooted. My carrier is Cricket. Here is what happens:
1. If the phone is connected to a WiFi network, I am unable to send text messages. The message will attempt sending for a while and then basically timeout. The app will report that the send failed. This will happen no matter what application I use (Hangouts, Google Messenger, chompSMS...). If I'm on the cellular network, texts send find. EDIT: Actually I'm seeing that's not actually true. Even when I'm on LTE, there's no guarantee messages will send. I can't actually detect a pattern here.
2. I am unable to switch from WiFi to cellular data by turning WiFi off. If I'm on WiFi and I disable Wifi in the Settings panel, the cellular indicator will change to show 2 or 3 bars of service with an exclamation point (!), seemingly indicating that I'm either not on the network or that I don't have data. If I reboot the phone I'll have full LTE.
I first started noticing the issues with text messaging back when I was running CM11 nightlies. Everything was fine and then a few weeks ago it started happening. I figured something had gotten messed up in those builds so I flashed to stock Lollipop but the problem persisted. I flashed to 5.0.1 and the problem remains. I also tried switching carriers from Cricket to T-Mobile, but T-Mobile service was so bad in my area that I had to switch back the next day; I didn't really get a chance to put it through its paces.
I know this is a weird one, so any ideas would be greatly appreciated. Thanks!

Issues with MMS, Network, and Wifi on OPO

I am having issues with receiving MMS, cellphone network, and Wifi on my OPO. I think this issue may be due to the a bug in Android and not specific to the ROM I am using. In addition, I think this issue is specific to OPO and not other Android devices. The reason I know is because for two weeks, I was using Nexus 6 with stock 5.1.1, and I never had any of the issues listed. I started noticing the issues again when I switched back to OPO. These issues existed in all previous builds of the ROM I am using.
I want to know if anyone else is having similar issues and how it can be resolved.
My carrier: T-Mobile
Build: BlissPop OFFICIAL-20150906
Baseband version: .3.0.c6.5-00007-M8974AAAAANAZM-1
Modem Firmware installed: Bacon Firmware May 15
Install type: Clean install by first wiping System, Data, Cache, and Dalvik Cache
The issues are as follows:
1) I am having issues receiving MMS. When connected to Wifi, I never receive MMS. I see that my contact sent me an MMS, but I have to first turn off Wifi then tap to "retry download of the MMS" for the MMS to show up. Another example is when I have a group MMS. I don't receive the message in the group thread. I receive MMS from individual contact, and I have first turn of Wifi and then tap to retry download of the MMS. Then only the individual message shows up in the group MMS. I think this issue is independent of the Messaging app I used. I ensured to to turn on automatically fetch MMS under the settings of the Messaging app I am using.
2) I am often in a building with poor network but connected to Wifi. When I leave the building, the phone disconnects from Wifi, but then also keeps saying no network despite the reception being good. I have reboot phone for it to catch on to the network again.
3) If I am talking on the phone, and I enter my house, the phone doesn't connect to Wifi automatically. I have to first disconnect my call for the phone to connect to the Wifi...
4) Issues 2 and 3 may be interrelated, because sometimes I noticed that when leaving a building with poor reception but connected to Wifi, I have to first disable Wifi for the phone to catch the network.
