Data connection keeps dropping

---

I'm running my Captivate glide on Orange network (device is unlocked).

I rooted it following all the steps shown in http://forum.xda-developers.com/show....php?t=1378082 (BTW, works great thanks).

I kept AT&T rom, but issue happens also with Rogers rom.

This happens only on 3G/3G+ connections.
WiFi works great.

The issue looks quite simple: data connection drops (very) often.
No more email push notifications, ...


Have to go to Settings > Network > Airplane mode : switch it on and then witch it off to get data connection back.

It is not an operator issue. My other phone(s) are using the same and data connection works.

Is this a radio rom issue ? Is there a fix ? (didn't find a thing related to that issue).

Anyone having this issue ?

Depends on how strong your network is, I have experienced this a few times.

I keep getting this now that I have had more experience with it, anyone else experiencing random sharp drops in data speed/connection?

Well, I have 4 out of 5 bars... Signal looks strong enough to me.

If I use the same SIM card in a HTC MyTouch 4G slide => Works great, no data connection drops at all !

Looks like it depends on what programs are running and using the data connection:
- email push - connection last long enough.
- when I'm running Bejive (IM) - connection last a bit less (before the 1st drop).
- when I add Skype & LoudTalks : almost every 5 minutes connection drops.

I also noticed that after a voice phone call, sometimes data connection doesn't (cannot) restart by itself ...

Here is an idea :
Is there a way to tweak Operator connection like it can be done with HTC phones : GSM + CDMA, CDMA Only ?
Because when you switch the phone to CDMA only, it uses different frequencies and allow to keep data connections while talking on the phone.

Didn't find that option in Captivate Glide settings ...

Settings --> Wireless and Network --> Mobile Networks --> Network Mode

Didn't make a difference for me using HSPA only.

I just checked ... I don't have the "Network Mode" option in "Mobile Networks" section.
I have Roaming, allow data connection, APN, ... but not Network mode.
Weird...

I checked the operator info. Nothing out of the ordinary there.

I'm stuck ...and it keeps happening. No solution for now.

Maybe try flashing the Rogers kernel and ROM since that's what I have?

Already did that, but that was a few days ago when looking for the WiFi tethering feature ...

I'll flash it back to Rogers kernel & ROM and test.

Update: Flashed Rogers rom.

Good news is I now have the Network settings back. (AT&T rom is not the right one, for sure !)

Data connection last longer. But the issue is still here.

Still investigating...

Anyone else having this issue ?

the day before yesterday, I went to the copier room in my school and stayed for about 2 hours (too many copying). before i get out, i have no signal (mobile network not available). I need to go out to have signal back or reboot.

It happened again yesterday on the exact same location, I'm going to be there again now.

I believe it might be location wise....in my case at least.
