[Q] AOSP/CAF erractic WCDMA connection - Sony Xperia M

Hi,
I flashed the AOSP/CAF beta rom developed by PecanCM, a couple of days back. The ROM as a whole has been functioning superbly, however the WCDMA internet connection has become very erractic. All I am getting are sudden bursts of internet connectivity. Any idea about the cause of this problem?
P.S. Before flashing this ROM, I was using FXP320, and the internet connection was more-or-less okay.

[Q] portable wifi hotspot disables 3G ?

had the phone over a year now, never had an issue before.
As soon as you turn on the portable wifi hotspot, i loose the 3g/h symbol from the top of the screen and from that no data conectivity?
and as sopon as you turn the wifi hotspot off, it regains an internet conection
Any ideas, ive not installed any apps recently, as far as i can remember?
Do you get an internet connection when another device connects to your phone's wifi hotspot.
If you are able to connect, then it must be working, as it's the 3G signal that the phone uses to connect the wifi to the internet. It might remove the icon, but if you can connect then it's fine.
nope, can conect my ipad to the DHDs hotspot but no internet.
the same for when i turn the hotspot on, cant brouse anything on the phone as no data conection
still not sorted this, anyone else got a aide or something to sort this?
First post (longtime lurker)
I've got the same problem here although this has only started happening in the last couple of days. The phone's data connection is fine until you enable the wifi hotspot at which point the connection is dropped to the phone, connecting any devices to the phone is fine, they get an IP address and can ping the phone directly, but beyond the phone there's nothing.
Rebooting the phone does not help.
The only app I've installed recently is Google Shopper.
Out of curiosity Fil what ROM are you using? I'm on RCMix3d Runny 3.0 which is based on Android 2.3.5 and Sense 3.5. I'm looking at switching to an ICS build pretty soon.
It also looks like we're on the same network although I think that's just coincidence.
yep sounds exactly the same issue,
as for rom, still on t-mobiles original 2.50.110.5 Adroid 2.3.3
was thinking of flashing something custom to see if it solved the problem
I've just flashed IceColdSandwich today at work (it's been a slow day!) and you'll be pleased to know that wireless tethering is working again. I'm on the train home as I type this. It's possibly something in the 2.3 image? I can't really say since we both had different ROMs (mine was a Sensation port). It could just be a bad bit of code in the gingerbread OS that produces this bug on rare occasions.
It may have something to do with the fact that T-Mobile and Orange allow you to roam on eachother's networks. Do you have roaming enabled?
To be honest I'm just stabbing wildly at possible causes here and a flash fixed it anyway. I went ICS but I don't think you'd have to go that extreme but flashing a new ROM overwrites whatever it is that caused this in the first place.
I'm just hoping it's fixed in ICS and won't happen again!
cheers, enabled data roaming, and it now works!
Since the issue, my batterys turned to crap! guessing thats the cause constantly jumping networks, and also data speeds have been very poor lately, was ok when just t-mobile, but orange is poor!
Off to the t-mobile foeums to see if its just me, or others!

[Q] 3g weak signal unique workaround

Using HTC desire with MIUI XJ GB. Since last ten days, the 3g signal keeps changing. Sometimes internet doesn't work even with signal.
However, when I download something with ttorrent in the background, connection is stable. I am now always downloading something at low speed to browse without interruption. Battery life has gone for a toss.
Does anyone know the problem. It can't be network problem since ttorrent is downloading smoothly.
I have tried other ROMS like supernova and cyanogen but no change. Reentered apn settings.

CM11 and ATT network issues.

I have been using Beanstalk 4.4.4 for E980 for quite a while and my phone has been hehaving well. But lately I can't make or receive any phone calls if my network is on LTE. I know that voice is on 3G (HSPA) but when I am on LTE and I make a phone call, the signal switches to H and then it disconnects after I hear one ring. Also, when I receive a call and I am on LTE, once I hit answer, the call disconnects. I then did factory reset and also flashed other CM11 based roms such as Vanir and Blissstalk and the issue persists. I searched on the web and it seems to be an issue with CM11 users with ATT such as Nexus 5 and one plus one users. The rumor is that ATT is experimenting VoLTE in the northeast area (I live in NYC) and that there is a problem in CM11 in that situation. My wife's S4 doesn't have this problem with touchwiz version of kitkat. I can fix this problem by choosing 3G as my preferred network but then I lose LTE speed in data.
So are there any other people experiencing the same problem? Is there a CM fix that I could flash to avoid this problem?
try this
You try changing preferred network to 3G from LTE, and maybe that should fix the issue.
I'm using e980 with CM11 snapshot m11, and starts about a month ago, my phone starting to loose the connection to the mobile network regularly. It happens when ever I reboot the phone, and I have to reboot the phone 2-3 times before it's able to connect again. I switch to the cm11 nightly 3 days ago, as of right now I have been able to connect to the mobile network each time I reboot my device. I saw a few complaints regarding this issue on the cyanogenmod forum. Just thought I share the problem.

Cm12 official: bad data connection

Hello everybody, I'm on CM12 since a few days (upgrading to the latest nightly on a daily basis) and keep having data connection problems. LTE or 3g connection in general are very unstable, they stay connected for seconds or few minutes and then they stop working. It seems to be an unsolved problem. Does anyone else experiencing the same and found a fix? It is really frustrating.
Thanks!

wifi disconnects: Which ROM to use?

Hello All,
like other people I'm facing wifi disconnects when the phone screen is off. When it happens the phones switches to LTE although wifi signal strength is good. Of course wifi options are set to "always on". I had these wifi drops with the original OOS and with the official CM13 ROM. I assume both use the same wifi driver in the kernel.
Did anybody had the same issue and found a ROM which solved the problem?
Any help is much appreciated!
Freedomos seems to be stable with good wifi performance. Orion is also very good with connectivity.
