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/showthread.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.

I checked, looks like it is not linked to a specific location. I've been travelling and issue kept occuring.
Once data connection is ok, it usually stays up for 2 to 5 minutes, then drops.
"4G" symbol is still displayed - but no more data connection. Web pages not available in browser, no email sync, no more IM, ...
While data connection is down, Cellphone still works, WiFi as well.
It may be linked to an APN issue ... Or definitely a Radio ROM issue.
I'm running Baseband I927RUXKJ5.
Anyone else having this issue ?
When I got the phone the AT&T rep told me there was a known issue with the phone dropping down to lower data speed. He told me if I experienced it to get a new SIM card. Doesn't sound exactly the same but maybe try that?
I've got a strange problem that I cannot solve or find anyone else that has had the same problem.
I recently updated to Minco V4 and since my status bar has been showing no signal and mobile standby shows 100% without signal yet I have mobile data. I cannot make any phone calls but can browse the internet. No amount of rebooting, airplane mode on/off will work. I've also gone back to both stock ICS and JB where the problem still exists.
My network is T-Mobile and it won't let me manually connect to it but the phone will occasionally register when I select automatic although it doesn't correct the fault. Anyone have any ideas what has gone wrong with my phone?
UPDATE: It seems I can only get a phone signal when select 2g T-mobile network only or connecting to T-Mobile orange. If I untick 2g networks and it connects to t-mobile 3g I can't receive or make calls.
Does your Radio and baseband match?
I installed the linked radio from the MiNCO thread after flashing the rom and discovering this issue yet it made no difference.
I got a phone signal momentarily about 15 mins ago which allowed me to make a short phone call to test it. I then accepted the JB system update from Google and now have no phone signal, just data.

Hi all
A search of the forums revealed 5 potential threads similar to this but not quite (not same symptom, phone, modem ...)
Keep loosing mobile data connection...
I have installed X-note 3 and found that my mobile internet is intermittent particularly in Youtube where I frequently have to click "No connection , Retry" or "Connection to Server lost, Retry" and in Play Store and Gmail where the problem tends to occur on a screen unlock after it has been unused for a few minutes - about 3 to 5 mins.
I dont believe this is a ROM issue because I d/l various ROMS such as Revolution, Alliance, PacMan, Paranoid and still I get the problem.
I tried installing all 9 of these radios here: http://forum.xda-developers.com/show....php?t=2044937 to no avail.
Also notice that if I set Network Mode to "GSM only" then this makes no difference to the problem (the default is "GSM/WCDMA Auto" which is what I've set it back to)
WiFi works fine.
Any ideas?
same issue here.
a lot of time trying to know why this happen. and i think it is due to fast dormancy.
the phone usually stays in standby in 3g... when you request some data it will automatically turn h or h+. Here is when you will notice the internet moving.
But unfortunately if you have some.coverage issues you can have this problem and then the programs instantly report no conection. If you insist you will see you can obtain connection. 5 seconds later 3g will appear again
It does not mind you will see the bars of coverage at maximum... if there is no quality signal you will have this problem.
I just have this problem at work. Not in other places.
But if you want a constant connection I recommend to keep for example online music while navigating...this will avoid the issue...unfortunately you will increase your data plan..
Yes!! This is exactly what happens.
So it can't be my specific phone but perhaps a hardware design or software issue. I don't recall this I happening before I rooted
Weird
Fixed it - so far at least
Fast Dormancy is the problem. It was enabled by default and I have turned this off. The connection is now fine and seems to be "always on". For me this is okay because I do not have any data limits or pay per MB for data. I do notice that new connections take a little longer to start (for example, time taken to access internet when opening up an app that is not currently running) . This is not noticeable for apps already running (in the background)
This explains ....

Hello,
I'm using two swedish providers in my phone - 3 and Telenor. Both are capable of LTE/UMTS, I'm using 3 as the primary provider for all options in the Sim settings and the Telenor one only to receive calls.
So I recognized a problem where my data connection would drop when the 'open wifi'-notification popped, I tried to disable that and it seemed fine at first. However I'm still getting data connection drops when me phone swaps from LTE to UMTS(3G/H/H+), no errors are thrown and I'm only seeing it due to no data loading within apps or disconnects in-game, the display isn't dropping the coverage indicator nor the indicator for which network is being used(3G, H, H+, LTE, 4G+). After some time the data connection returns but keeps dropping rather frequently once this pattern starts.
Airplane mode restores connectivity for a while (I haven't clocked it) but eventually the connection stops receiving data and the disconnecting pattern returns.
Calls and SMS are working as far as I've noticed so far.
Any ideas?
Edit: I've restarted the phone multiple times.
Any one got similar issues or any fix :3?
After a phone restart, VoLTE/4G Calling and Wifi Calling work for a short period, then stops working, usually after moving around between mobile towers and/or wifi hotspots.
I find it happens whenever the device loses mobile signal, or when the device flips down to 3g and then back to 4g, 4g data service returns but both VoLTE calling and WiFi Calling remain disconnected despite being enabled in settings.
This happens on my primary SIM only. I have a second sim in my phone at the same time which works perfectly with both VoLTE and wifi calling. I upgraded from a Mi 9 phone which worked perfectly with both these SIM cards.
Looking at the device logs (With Logcat reader), I get lines like
QImsService] ImsServiceSub : [0] Permanent IWLAN reg failure (IKEv2 auth failure)
I also see
IKEV2ErrorReceiver] Canadian configure is not set, return
Other things I've tried:
Updating to the latest MIUI version (12.1.5.0)
Network settings reset
Only using the one sim
Removing the second SIM
Clearing all caches
Clearing caches and storage of things like CneApp, Carrier Services, Phone Services, Phone, anything carrier related
Resetting APNs, adding APNs with bearer set
Setting phone to prefer 4G/LTE (ie do not connect to 5G)
Removing my VPN, same problem with VPN installed or not installed.
Removing sim cards and leaving phone off for a while (an hour or so)
Getting a replacement SIM
I have not tried a factory reset yet, as I am not confident in being able to back up the phone fully and other threads with similar issues suggests that won't solve the problem.
One way I've managed to get it stable is to dial *#*#4636#*#*, go to phone and set preferred network type to "NR/LTE". The phone does not connect to 3G or below in this mode, and unfortunately this setting gets reset when the phone restarts.
At this point I think its a problem with the MIUI software version itself, or some firmware driver that comes with these versions of MIUI. I'm hoping MIUI 12.5 will fix it, but I'm wondering if anyone else has seen this issue or knows what else I can try.
Upgraded to 12.5.1.0(RJDEUXM) and the issue is still present, also tried asking my operator to completely reprovision the line with no luck.
I guess I'm stuck with this behaviour until I upgrade my phone
STEP #1) See if VOLTE works normal when switching towers with a different phone.
If it does then you can try the things below, if it doesnt maybe it might be the cellular carrier issue.
If other phones work find then please note that VoLTE mainly works on 4G LTE ... donest work on 2G or 3G and may or may not work on 5G depending on your carrier. Find out what NETWORK BAND your phone is using when VOLTE is working. You can use a app like
Network Cell Info LiteOnce you find out the band you can then use a script or use a app so it stays on that network BAND. A little more advance but it may also possibly be a DNS issue in the tables during the change of towers during the reprovisioning... you can try a script to flush the DNS and reload the tables when the network info changes or bind them statically for testing purposes.
Still doesnt work it may just be the firmware's modem issue with that phone in the way it handles re-provisioning process during cellular multiplex switching.
