Lollipop looses data connection. - Nexus 4 Q&A, Help & Troubleshooting

Well more specific, data throughput stops but the connection is still active, full reception etc. The only way to solve is to reboot or toggle aeroplane mode. Did not have this problem on KitKat. I have internet speed meter installed so I can see when no data is flowing.

3G Data connection Issue

Hi there,
Sometimes, when I try to update weather data / anything else throught data connection (3G), my device say that I'm connected to 3G network but nothing seems get through the connection.
I've to restart all the phone part (switch to plane mode and go back to phone mode) to be able to get connected.
Is anyone encounter this issue too ?? Any idea ?
PS : GPRS Monitor say that I'm connected too, but the download/upload indicator stay to 0 kB.
Thanks for your help

Connectivity issues?

I've found I cannot connect to Facebook sometimes, upload pictures to skydrive, or use xbox live, and find my phone only kinda works sometimes. Am I missing something? I set up my LIVE account and Facebook account during initial setup.
You are connected to Wi-Fi or 3G when you try these things right?
If you're using 3G while doing these things, it's possible that you are having some weak signal strength in your area which is probably not enough to connect to those services.
I've been doing these things over a strong 3G signal. The data connection drops in and out. Sometimes turning on airplane mode then turning it back off will restore data. However, it shows 3G the entire time. I have no visual cue that the data isn't working unless I try connecting to a service and it errors out.

Do you have the same issues with a wifi connection?

[Q] Loss of mobile data connectivity - AT&T

It happened 4 times on my Note 3 in the last 10 days. I'm home or at work under wifi. Go out and try to use mobile data and I get an error message that I have no connection. Yet my LTE signal shows 50% and above in signal strength. I tried to turn on airplane mode to turn it off to force my phone to latch onto the closest cell tower and it's still doesn't fix the issue. If it happens while I try to upload some files, I check my email or try to browse the web and it confirms that I have no working connection to the web. I end up rebooting my phone and it fixes the issue. It's as if the phone is still looking for my wifi connection and "forgets" to switch to cellular connection once I leave the building. I know there is a setting under wifi that says to auto switch between wifi and mobile network but it doesn't seem to make a difference.

[Q] Keep losing WiFi connectivity

I have an SGH-I337 that is running Cyanogenmod 11-20151112-SNAPSHOT-M12-jflte with baseband I337UCUAMDB, and I am experiencing some odd WiFi behavior.
The WiFi will be connected, showing in both the notification bar and the WiFi settings, the notification bar with show traffic (blinking up and down arrows), and yet apps won't be able to access the network. I can restart the WiFi via settings and this will usually restore app connectivity, though not permanently; eventually apps will lose connectivity again. Rinse; repeat.
At times I'll get annoyed at having the WiFi problems and turn WiFi off and use LTE. However, the WiFi eventually turns itself back on, often times exhibiting the connectivity issue that drove me to switch to LTE.
Another issue is that the WiFi will forget the settings for a given network. The WiFi app will simply show the network, not indicating that settings are saved, and I'll have to enter them again.
I haven't been able to establish a pattern to these issues, and it's driving me mad! Has anyone seen anything like this? Have any suggestions, besides taking a handgun to the phone?

Data connection continuously drops

After restoring Stock ROM from AOSCP(CypherOS), when switch on data connection, it keeps automatically turning off & on repeatedly. After a few minutes data connection become stable.
Any idea why this is happening & solution?
