Loosing connection on android 4.4.4 - Nexus 5 Q&A, Help & Troubleshooting

Currently I'm experiencing the following annoying problem:
My phone keeps loosing connection to my provider (KNP, NL) in areas with normally full signal strength (city center, rural areas everywhere). When I put my phone in airplane mode and switch airplane mode off again, the connection is back.
After posting this problem on a Dutch (tech)blog I got responses that people experience the same problem with their Nexus 5.
This error happens with different Roms.
Anyone with tips / more insight?

[Q] Help with diagnosing data connection issue

I'm having a bizarre issue with my HTC Desire HD where the notification bar shows 4 bars of coverage (the max available) and the data connection shows 'H' (again, best possible), but the data connection often freezes/stalls/fails. Changing my data connection to 2G only fixes this issue and I get normal 2G connectivity with no issues. This is happening inside the building I work in (in central Edinburgh). I also experience this is other central edinburgh areas outside. However, further afield 3G works just fine.
Can anyone suggest what might be wrong? Alternatively, are there any tools which allow you to monitor the strength of data connection the phone is making? Or other diagnostic tools? Thanks!

[Q] No data transfer on UMTS

Hello all,
Been using this phone for ~6 weeks now.
Familiar with all 3G/H and no network issues - been there, done that...
Yet, I find it odd that while my phone is sometimes steady on UMTS, it has no actual data connection (Ping fails and also other tools), while calls can be carried out!
Also, at times, while network signal is showing as working, I'm actually w/o network connection (phone calls) at all.
And last, in several occurrences a day, while I'm not in a call and probably also not in 2G (I restricted my connection to WCDMA only), I get Network signal yet no data signal in the notification bar (WIFI is off).
I tried re-flashing 1.78 EU RUU (for my unbranded phone) with no change.
I tried rooting and putting Lee's ROM with no change.
I switched microsim from my provider with no change.
Is my only solution is sending it back to HTC for repair? or there is another solution to that frustrating (!!!) situation?
Many thanks for any response!

3G Data disconnection

Hi. Is anybody else having issues with the 3G icon being displayed, despite having no data connection? I get this on occasion, and my only solution has been to cycle airplane mode and hope it connects to the 4G network. My best guess is that my connection is poor, and 3G is just an indicator that it's connecting, not actually connected. I'm on stock, S-off, root and TWRP recovery. Any help would be appreciated, or anyone else having this issue so I know whether or not I'm alone.

Low / no GSM signal after update

Hi there,
I have updated my phone through "Wireless Update" found in the System menu and since it's been updated I have either low signal or no signal at all (depending on location). For example, at my workplace there isn't much signal strength by originally but my phone was available at 3/5 signal strength marks. Now I have Zero marks and no network, nobody can call me all day long. At home, the signal strength was 5/5 before now it's 4/5 constantly but if someone calls me it drops to 1/5 or 2/5 immediately.
My phone is a THL4000 with KitKat 4.4.2, MTK6582KK
Would you please help me how can I solve this problem?
Today I found out it's a phone issue and not the carrier.
I tried to switch my SIM with my colleagues' phones and my sim worked just fine, while I tried their SIM in my phone too and still no signal even with another carrier. I also contacted to my carrier and they made zero change to the signal strength or anything else in my area.
I also did a Factory Reset to my phone from the system menu. I'm not sure it reverts the recent system update that may cause this issue, but nothing has changed - again. No signal at all at my office. It worked just fine until last week and I made zero damage/fall/etc, only a system update.
So please, does any of you have idea what causes this or how on Earth can I fix this?
Thank you.

I do not have any connection issues to the mobile network. Can you check at another location?
OP, try "Mobile data always active" in Developer settings. Also try "Reset Wi-Fi, mobile & Bluetooth".

I have some network problems too on my 2 days old Asus zenfone 6. The signal from mobile network is lost for few seconds and imediatly after the signal of wifi is lost. Does anyone have a solution for that?
No network issue as such.
But mobile network standby battery is twice that of screen battery consumption. Could be both are related
Yes, I am having network issues but I am not sure if its the phone issue or airtel network issues. So waiting to see if it fixes after few days.
I have network issues since updating to the 156 firmware. While having full 4g reception the phone switches to 3g for a few seconds without success and then 2g. It show full 2g reception but everything i try runs into a timeout. Switching to 3g only brings back full 3g connectivity most of the time, switching to flight mode and back does not help. Rebooting the phone does not help. If i just let the phone sit in 2g without a connection it "fixes" itself after 10-15 mins. This happens a few times a day. I have tried using different providers (tmobile and vodafone) but the problem remains.
