The status bar says that I have 4G LTE data, but no data connection happens.
I put the phone into airplane mode and then back, then data connection gets restored. This happens maybe once 2-3 days.
Has anyone has gotten this issue? Perhaps custom ROM will resolve this issue or maybe custom Kernel, I have not tried anything yet. Just wondering maybe there is a setting missing.
Thanks.

Ok, first up - Stock ICS 4.0.4 ROM, custom kernel (HydraCore v4.3), nothing changed on phone recently prior to this occurring.
Some time during the night (presumably) my Note has decided it does not work when it comes to mobile data. On waking I found the stock weather widget had not updated, the stock browser would not load any pages and the Facebook app said could not connect. Over wifi, these all work fine. Calls and SMS work fine. The weird thing is the status bar indicates I'm connected to H+, H, or 3G, and the upstream and downstream indicator arrows light up whenever an app tries to access the net as though all is fine. I find it odd that this has happened without anything being changed or touched on the phone, and with it working flawlessly for months with the current setup.
The website for my provider indicates no faults located either at home or work, could this still be network related?
Short of loading ICS again, I've tried everything I can think of. Cycle power, double check and toggle all data/network settings, reset APN, etc.
Just thought I'd check here for any ideas or a simple fix I may be overlooking before I go flashing ROMS (which may or may not fix it).
Thanks for any help,
Nick
Did you try with another sim card dude.

That might be an EFS partition corrupt, go to settings >> about device >> status >> IMEI
see if your IMEI is there or not
I have been having this issue for a bit now, it hasnt been like this always but only recently.
I also noticed that there was another user who was complaining of the same issue on a KK rom as well.
I have had this issue on Dirty Unicorns and Spirit Rom
I am going to give SlimSaber a try and see if it persists on that as well.
I know it could be network issue but I have never had this problem until recently and I did not change residence etc.
It shows connected in the status bar but there is no is absolutely no data transfer till i turn it on and off. And sometimes even that doesn't work and I have to turn of airplane mode. And this happens every 10 mins so I am sure it is no some sort of connection time-out issue
APN settings seem to be fine and such and I am out of ideas.
Could it be a ROM issue? Any suggestions as to what could help?
I am sorry for the horrible typos!
Tried slimsaber but issue persists
Updated the modem to the one for my country and it might help? idk
I have found that whenever my phone loses signal and then regains it, I have no data connection until I restart the phone. Even toggling airplane mode or manual signal search does not restore data. I have tried disabling 4G but that doesn't make any difference. I also don't have WiFi on as I never use it.
Does anyone else have this same problem and know a solution? It is extremely frustrating having to restart my phone up to 5 times a day and not receive emails etc.
I had more or less the same. What helped in my case was adding the apn of my provider manually instead of letting the network and phone handle it.

this can cause by network or firmware bug
you can manually add APN if system delete it then repair Firmware by PC Companion
:good:
I have the same issue.
Have you managed to resolve it yet?

Not yet. I have tried deleting the apn end adding it again myself but it's the same.

my problem may be slightly different in that I could not connect to Internet when out of wifi range unless I did a restart.Resolved by switching off stamina modes.

It works for me. Next week the Z3C will be updated to Lollipop. Let's hope it will solve this bug.
i'm experiencing this problem since upgrading to marshmellow:
when in low signal areas i have a problem with the 3g/lte modem not reconnecting after finding a signal again. I can see 1 or 2 bars but data doesn't work. I need to flip airplane mode on and off. i'm on TMO, not rooted. Anyone else notice this?
Something strange is happening here on my Pixel 5. It looks like the modem keeps resetting. What happens is this: the bars for cellular drops and I get a small x (like it is disconnected), then wifi shuts down. A second or two later, the mobile network comes back, and says 4G besides the bar. A couple of seconds more and wifi reconnects as well.
To me, it looks like the modem is restarting. This happens after a couple of minutes using the phone, and keeps repeating every 5 minutes or so. I have tried to replace the sim card, resetting network settings, restore to factory settings, reflash stock firmware, tried boh April and March updates. Nothing helps.
If I remove the sim card completely, the wifi connection drops and no networks are visible, so I can not connect to anything.
This is the strangest thing...! I am going to try to flash a custom rom, probably proton to see if anything changes.
I suspect that this is a hardware failure, but has anyone seen anything like this? Any more suggestions on things I can try?
I have this exact same issue, did you find a solution?
