[Q] Radio Issue? - Nexus 4 Q&A, Help & Troubleshooting

I have an intermittent issue that happens in multiple locations and on both WiFi and 3G. Occasionally, when I have good signal strength (3-4 bars) and have a blue "connected to Google services" status, I cannot connect to the web with any app. The status will sometimes show as connected to Google services for 30+ seconds before the network status goes to grey and shows no data. After that, it can take another 30+ seconds for the network status to reset and then I have network access again.
This isn't always the case, and I sometimes unlock it to find it on the grey "no data" part of the cycle and have to wait for it to reset before I can do anything useful. I am on CM 10.1-M1, and have seen this with stock kernel and franco nightly. My network is T-mobile, though this happens with WiFi too, so I doubt that has anything to do with it.
Are there any radio updates or other fixes that might stop this behavior?

I get this problem too. It stopped since I moved to my new apartment. Dunno what was going on cause I had full h+ signal and out of no where, data would drop. Happened multiple times a day.

HD2 Radio Has Horrible Instability

Is anyone else here having similar problems with the radio on their HD2? Mine seems to crap out severely when it comes to 3G. I have notice dhtat just about every time the phone is powered on, it will turn the data connection in the settings off by default regardless of It's state when the phone was previously powered on.
Also, I have noticed sometimes the phone will sporadically switch out of 3G mode and into phone only mode and I must go into the settings menu and re-enable it.
Also, Sometimes (The phone has done this twice today so far), the phone will still indicate that it is in 3G mode but when I attempt to browse the web it will return a page cannot be found error and the only way to fix this is to go into settings, disable and then re-enable the data connection.
My current radio version is 2.08.50.08_2. Is there something better out there?
I had the same problem with the data connection shutting off. I downloaded HD2Tweak and it helped keep it on.

It's been a while, but I think I got it here. It was the English version.
http://www.montecristoff.com/hd2tweak.htm
Under "4. Data", I turned on Internet, MMS and Data to be on permanently. Worked like a charm. First day, I had 13 hours straight of data connection. Before using HD2Tweaks, I never had more than 20-30 minutes.
I've noticed today the 3G connection went from full bars to none and also no phone bars.. and it reconnected again.
Sometimes it will not reconnect to signal for a while after I leave underground train station.
In areas of weak-medium signal strength, I've noticed it switch between E and 3G a lot and drain battery much faster.
The signal reception is generally excellent in the city, except if inside a building with thick walls, so I don't understand why it has signal issues when outside.

[Q] cellular radio problem?

Now I want to know is it related to this thread:
http://forum.xda-developers.com/showthread.php?t=882518
Every time when the phone stays under "no signal" condition for more than 10 minutes, the phone is unable to regain signal when the signal is back (grayed out signal bars) except do the power cycle.
I need to decide whether it happens just on mine or similar to the thread above and I may send it back for exchange, or wait for updated radio ROM to fix.

3G connected but no data on Xoom

Anyone else had issues in which the Verizon 3G is connected and shows good signal (2-3 bars), but the signal bars are grey (instead of blue) and data doesn't work? I have to reboot it to resolve this problem.
I am also having this problem with WiFi in which it shows great signal strength, but the bars are grey instead of blue and no data flows. This one normally resolves itself after about 1-3 minutes.
I've seen people report issues with a WiFi memory leak issue, but nothing about the 3G doing the same.
Guess I am the only one having this issue. But I am tired of it now and it's going back to Verizon.
I have attached images of what it looks like when it loses the data flow, and one right after rebooting showing it working after reboot.

[Q] defy+ data network woes

i have a variation on the data network problems, not as annoying as reboots,
but getting close.
normally i am on GSM only, as my data needs are low and it extends
battery life. for hours, everything is dandy. then i notice that
the "G" icon and the signal bar are not blue anymore (stock theme)
but grey. 'settings' say i am still data "connected", but in fact
data connection is out (the operating system thinks there is
data connection, browsers and mail clients keep spinning and
trying until timeout).
turning on and off wifi makes the phone try to connect to the data
network again. sometimes this works, but more often that not, i have
to switch to 3G mode for this to work, and sometimes even that does
not help, and i have to go airplane mode to turn the radio on and off
completely. otherwise it just tries and tries and tries to reconnect,
draining the battery like crazy, and sometimes resulting in these
mysterious reboots others are experiencing as well.
is this the phone or a network problem? (tmobile in the netherlands)
i was on the same network, same SIM with an older LG android phone
and i dont recall having this problem, so i am a bit hesitant
to blame the network for every outage...
should i just send it back for repairs/replacement?
system version: 45.0.74.MB526.Retail.en.DE
baseband: EPU93_U_00.60.00
for a while i will keep the phone in 3G mode to see if the same
problem exists. as my mobile data needs are low, it would be
a shame if i cannot keep it in GSM mode because of this...
I had the same problem couple of months back but since I'm on msginger don't have that enjoying problem anymore.
Ohh and as far as remember it was only when the battery was on maximum save, now I'm using custom and it's fine

i am on custom saving mode. i think that the saving modes, where
the data connection is cut off after some inactivity, just flesh out
the problem more, as trying to connect back to the data network
happens more often then during normal use, when data connection
is kept alive all the time.
since i set the connection mode to 3G or better, i did not have the problem
but that was only a couple of hours ago. sometimes a day goes by
without manifesting itself...
I'm on 2G all the time. And the custom saving still got set up for cutting the data off but i don't seem to have that problem anymore i can check later on if it would still appear on max saving.

so after days, it seems like i cannot reproduce these problems
while on 3G. seems like 2G only for data is not 100% reliable
either because of the phone or the network itself, or both.
pitty.
i m having problems with network reception with the 7.2 CM rom on the defy+.tried the baseband switcher in this link but still little or no reception
http://forum.xda-developers.com/showthread.php?t=1203297
i have been on 3G last couple of days, and no data woes.
however i had a spontaneous reboot, so the reboot problem
is seemingly not only a 2G issue (if it is)..

Mobile Data will not enable!! (Dynamic Kat)

I need help this is driving me insane!
I've been running Dynamic Kat Rom for about 6 months or so now. Everything was working fine then all of a sudden a week or two ago I noticed my mobile data is not enabling at all.
I can only connect on Wifi and only receive SMS.
I've tried
- Messing will all the data/network settings
- Turning Mobile Data on and off -- no effect
- Toggling Airplane Mode on and off as suggested in some places
- Wiping everything but Data and reflashing latest ROM
- Reseating the SIM card
- several other things I forgot..
I do see the carrier information in the top left (AT&T) and I am getting signal bars.. but not indicator for 4G/LTE/etc
I've been messing with this for a week now and it's driving me insane.. I can't get a connection anywhere unless I'm on Wifi.
Anyone have any suggestions? I'm not super phone savvy, but willing to try any suggestions anyone may have.
Hmmm.. weird.
So I called AT&T and asked them about it.. figuring it could possibly be a carrier issue.
They told me to try things I had already done 100 times.. turn the phone off and on.. turn wifi off... etc.
I turned Wifi off... (which I had done 50,000 times before) and 4G popped up.
I guess they did something. So.. guess it's resolved.
Problem has returned.. same issue. I will have 4G signal for hours and then all of a sudden it will drop completely and I can't get a data signal no matter what I do.
I see AT&T in the corner and have signal bars, so I AM getting some kind of signal.. but no data connection whatsoever.
It seems completely random and intermittent.. I can have data signal for days with no issues then I will lose it for days.
Restarting the phone 5-20 times sometimes fixes it.. but that's about it. Anyone have any ideas what could be causing this?
Bad signal / carrier issue?
Call them and report a fault in your area?
I have called them multiple times, they will reset the signal.. sometimes it will come back right away, sometimes it wont.
And this happens regardless of where I am. I know for a fact where I am right now has a great signal strength. I get 4-5 bars on average. But this also happens at home as well about 20 miles away, which also has a good signal, or anywhere I go really it can happen. This isn't in the middle of nowhere either, it's smack in the middle of SoCal (LA/OC)
I'm beginning to think it may be a SIM card issue or a hardware issue with the phone. I'm going to try asking them to send me a new SIM card.
Another thing I will notice is when I have a working 4G LTE connection, and I'm on Wifi... it will sometimes CONSTANTLY switch back and forth between wifi and 4G like every 10 seconds, even when I have full signal strength on Wifi and 4G.
Disable Smart Network Switching in WiFi settings
it's nothing but a buggy headache, disabling might fix most of your problems, almost certainly the constant switching back and forth
Yeah forgot to mention I have disabled that. It's disabled now. It solves the constant switching back and forth (when I actually have a data connection), but that's kind of a separate issue as the losing data connection.
