[Q] Connection Issues on 3G and HSDPA

Hello everyone, anyone here suffered issues on their DHD when being oh 3G or HSDPA?
I'm from singapore and I'm running on Starhub's network.
What I see on my DHD is that the reception strength is full. and when I attempt to connect to the internet to browse websites or android market or whatever that requires internet connection, I would see the upload arrow light up...
However, it stays either lit up for a long time or just goes on and off... and I don't see the download arrow light up at all...
Only after a long time when it finally decides to disconnect itself from the network and reconnect itself again, then I can get internet connection.
I can also resolve it by manually forcing the radio to reconnect itself.
Anyone experiencing this too? I'm wondering is it a fault on my device or a common DHD problem.
I'm on stock Rom updated to 2.2.1

Serious internet issues..

Hey everyone, I've really annoying Internet connectivity issues on my onex, half of the time it's connected to the mobile network showing the "H" sign on top and the rest of the time it's showing the "3G" icon.
Now my issue is that while it's on the 3g the internet just stops - while playing it disconnects, on the browser it just loading forever, and on programs it get stuck.. while on the H everything is going fine!
I am living in Israel and worked with partner and now changed to "Pelephone" which should have the fastest/best mobile network, and it made no change. I also tried according to.an advice i got here to change my phone on settings to "wcdma only" and still no change.
Please, if anyone has any.idea about this problem and a solution i would be greatful.

Go check the network status in settings if it's hspa then it's 3g....if it's hsdpa then it's 2g

[Q] 3G > 2G switching issue

Hi everyone, I searched for a solution for my problem for a very long time, but found nothing. HOX has many issues with gsm network or signal, but mine HOX has a very strange issue with network mode switching. For example, I'm on 3G now and I set the WCDMA prefered in *#*#4636#*#* menu. When 3G becomes unavailable, HOX tries to switch to 2G network. But instead of switching to 2G, I get "No Sim card" icon and after ~30 second network icon disappears. I have to reboot the phone to recover the network. I made some tests and found, that this is not the hardware fault. I tried to change the radio RIL to any available and there is no difference. For now I don't know what to do, what else can I do... I will really appreciate any suggestions.
I can record a video to get things more understandable.

No signal when use 4G network for a period of time

I just changed my SIM Card from a 3G SIM to a 4G SIM recently. However I met an issue, whenever I use the 4G Mobile Network for too long (like 1-2 hours), the phone will suddenly lost all signal for 5-10 minute before recovering the signal. The signal bar is empty, and it appears the "Emergency Call Only" stuff. Is it just me or everyone is encountering this problem?
I have no problem at all when restrict the phone to connect 3G/H+ network only, it only occurs when I connect to the 4G network for a period of time.
My friend that uses the same telco with me doesn't have such problem (disconnecting/no signal at all) when connecting to 4G network, and it doesn't seems to be the antenna problem since the problem does not happen when I connect to 3G/H+ networks.
What might likely be the cause? Is there any solution to this?
Sorry for bad English, not my native language
(I live in Malaysia, and using UMobile Telco. )
Now that you mention it, I have pretty much the same issue of losing signals, and the problem hasn't occurred ever since I stopped using 4g. I didn't notice it was because of that, because I changed the phone too while changing the sim. I have marshmallow by the way. Don't know if that might be linked to the problem.
