Loose 3g data when Wifi is enabled with CM6.RC1

There have been a few discussions about this, but I have yet to find a solution that works for me...
I flashed CM6 today and now I'm finding that when I enable wifi, my 3g data connection is lost. Not sure this is really a CM problem, I just want to find a fix.
My setup:
Nexus One - CM6.RC1 - FRF91

what do you mean it's lost.. when you're turning Wifi on, that's the whole point (that you want to use your Wifi connection for data, and not your mobile 3G data.) Maybe I'm not understanding you?

Even with wifi on you still need 3g data to send and receive MMS. I can't replicate this problem, though, so I'm afraid I'm not much help. All I can suggest is trying a full wipe of everything but battery and rotate stats and try to flash it again. See if that helps.

It works fine for me. Are you sure you are confussing not having both icons in the notification bar with 3g being off?
I answered this question a few months ago too.

Your 3g is not lost, it just hides the icon. Go into settings and look what network you are still connected to for yourself, it will still say 3g. If you were to send or receive an mms the 3g icon would briefly pop up, send the message, then disappear. Your phone is working just fine

thanks for the help... @roger, you are correct, i didn't realize that the icon was hidden vs. actually turned off, nor did i think to go check the actual service rather than rely on the icon

[Q] Wifi Sharing on Tmobile Woes

I run CM7 nightlies on my Tmobile N1. Recently I killed my cable Internet/TV connection at home and have been using the built in WiFi tether for my home devices.
While it typically works great (for free), the data on my N1 will lock up. I have full 3G/HSDPA at my house. Using #*#*4636*#*# it states I am connected but fails to ping or load up any data on the phone or through its shared connection.
The only way to fix the problem is to toggle airplane mode and re-enable the WiFi Tether or sometimes a reset is required.
I've changed to several Gingerbread roms, flashed various radios, and even exchanged SIM cards.
Is this behavior normal or not? For regular web surfing I can live with it, but the main problem is that I cannot download anything without it getting interrupted (like updated nightlies or 50mb+ files).

Bumpity
No one has any problems with their WiFi sharing?

i used my phones internet as my regular home internet for a month. i used up about 25 gigs. i streamed videos, downloaded videos and podcasts with no interruptions. don't know what your problem could be. i was using cyan 6.1.1

I occasionally have experienced that issue, but it seems as if you have it much more frequently than I ever did. I would mainly get it when I tethered from areas with bad reception.
You state that you have full 3G/HSPA at your house. I am wondering how many bars of reception you happen to have. Also, try setting your phone to WCDMA Only in that 4636 menu. That seemed to decrease the frequency at which it happened for me.
I also found that once in a while, I could get tethered data working again by simply using the phone's native web browser to access any data. Good luck with the issue.

I typically have full bars of signal usually reading around -100dbm. When the internet drops, it drops completely; maps, browser, apps, etc all fail and I can't "jump start" it other then toggling airplane mode or resetting the phone. Typically a reset is best.
Perhaps I'll flash back to CM 6.1 and test it over the weekend. I'll do a backup of my current setup if things aren't fixed.
The purpose of this thread was simply to see if others have experienced the same issues and if it was worth "trying" to fix.

It might be a case of overheating device - it'll be good to test different ROMs and kernels.

I don't think the device is over heating at all rather then just a carrier issue. I flashed to CM 6.1.1 over the weekend and immediately found I was still having data issues (where it would work for like 5 minutes then drop out).
I did find that EDGE was a solid connection and stayed connected while I downloaded CM7 and GAPPS. I put a call into Tmobile and yacked at them for several hours. They escalated it up several times in their engineering department and so we'll see. I spoke to HTC a few times in there and they didn't think it was a handset problem either.
I guess we can close this thread as it doesn't seem to be a wide spread problem. I am running a stable version of CM7 now and we'll see.
@above: I have tested different radios, roms, and kernels. This thread started out as a issue with WiFi Tethering but ended up being the phone simply dropping its data connection. I originally was curious if this wifi sharing behavior was normal or not.

LG Optimus 2X P990 - Service Problem

Hello,
Since a couple of weeks I've been having some issues with my beloved phone: the LG Optimus 2X Speed (P990) running the latest and greatest Cyanogenmod 7. And I was hoping that you could help me with that.
The Problem
My phone, and my previous phones have always had great service reception. I would never find my phone with two bars or less, unless it was brain-dead out of juice. I've always had the same provider (T-Mobile NL) and I've never experienced any problems with them.
However, in the last couple of weeks my phone can't find my network more often and often. I'd check my phone to see why I haven't gotten text-ed in the last minute or so, and it would be offline. Zero bars and status "No Service". At the beginning, I could put Airplane mode on, and then off again and it would reconnect. But since a couple of days that won't work either. I can put the telephone into airplane modus, but it gets stuck in it.
The button remains gray saying "Disabling Connections". If you go back, and into the Connection settings again the button can be pressed but indefinitely keeps the phone in airplane mode. The only way to enable connections again is to completely restart the phone. And as of lately I find myself having to reboot the device about 1-4 times a day.
Could you help me with this?

Obviously CM7 went a little crazy! I don`t think it`s hardvare problem and the most safe and secure thing u can do is to go back to stock rom and root and reflash CM7 again!!! Android is weird system and many weird things happen to many people. If u have few hours to spare u should begin there and see what happens. If that doesn`t solve your problem than u can start thinking about hardware failure (maybe SIM card, maybe phone antena). But i`m allmost positive it`s software isue. :good:

Disable the automatic date and time (network-provided one). See if that helps.
That was preventing my P990 from getting network at all after a cold boot.

Hi,
I have exactly the same problem. Disabling network-provided time helped (i.e. the phone connects to the network and data connection is up), but I was wondering if this is a bug and if there's a thread or a resource discussing this issue? Btw, the phone has been having some minor connectivity issues in CM 7.1 as well, but otherwise CM7 is useable.
Phone: LG-P990 (Optimus 2X), "Made in Korea" under the battery, does that mean for sure it's the SU660 flavour?
Carrier: Fido (Rogers Wireless), Canada
ROM: CM 10.1-20130722-UNOFFICIAL-p990 (tonyp build version 5) (Wiped and flashed on 2013.08.27)
Kernel: 2.6.39.4-kowalski-exp
Basebands tried: (none get me data connectivity)
LGP990hNAT-00-V25h-FID-CA-FEB-22-2012+0 (Original)
725 V10d (shows as Unknown in About Phone)
450 V20m SU660 (EDGE only)

OK, Correction...
Only the Wi-Fi connection was up. The cellular connection indicator was blue, which has led me to believe that cellular data connection was up as well. When Wi-Fi is disabled, the cellular connection indicator goes white and there's no data connectivity.
Furthermore, even though basic cellular connectivity was available for approx. 8 hours during the night, as soon as I left home and started moving it started dropping out. For example, I was only connected ~30% of the time for the past hour (and the reception along my usual route is normally great).
Toggling network-provided time doesn't seem to have an effect now, but the old tricks (toggling cellular connection, going into Airplane Mode, rebooting phone) seem to restore cellular connection for a brief period.
I also noticed that often when I would launch a data-using application (Internet browser, gmail app) cellular connectivity would be lost in a minute or so (saying No Service).
I've tried looking into "logcat -b radio" for ideas, but I don't quite understand what's happening here (willing to learn though).
Help...

I have installed CM7.2 (official CM) and CM10.1 (tonyp 5, oldbl) with dual boot and can now switch between the two ROMs. I have good cellular and data connectivity in CM7.2, but no data connectivity even after a fresh install of CM10.1.
I assume the baseband has nothing to do with this since both ROMs are using the same.
So, armed with a dual boot device, the n00b is ready to do troubleshooting! It only needs guidance now... Help?

[Q] Gsm connection

I have flased a couple of roms and I am currently on Ultimate N7000 XXLSC v5.1 but I have had this issue in previous roms. When doing any on device browsing or data connection, I get continious timeouts, although it sometomes works (very slowly). 99% of the time I would just receive a no connection error message.
Even though I have H or atleast 3G icons displayed at the top. I have found that when I use my phone in tethered mode (mostly wifi) and connect with my Laptop I get full connection speeds (1Mbs and up) I have looked for a setting saying only wifi, but haven't found one that makes a difference?
Where should I look? Or what can I do to fix this?
It did the same on my previous roms and I did do a complete wipe and even formatted the external flash.

Have you checked parameters from your GSM providers ?
Take a look at Settings->More Settings->Mobile networks->Acces point names.
There are entries with parameters for each.

As I mentioned, when connecting via wifi/usb tethering form laptop (no other internet connections) I get full gsm speed. So I am thinking it is some setting from the phone itself specifying wifi only is "stuck" I do occasionally get a gmail notification and whatsapp/talk message. But it is very slow.
Browsing a site on my phone and at the same time accessing that site from a tethered laptop/tablet would result in the site timing out on the phone and almost instantly loading on the tethered device.

The problem sounds coming rather from GSM configuration. In tethering wifi mode the GSM is not in use.

you might want to reconfigure your APN Settings by contacting your service provider, you can also try different SIM to check if you have same issue (chances of which are less)

Signal Issues

It is quite common now that almost all of our beloved ROMs are "infected" from the well-known issue of signal dropping. The "No Service" indication appears and you're unable to make calls, send messages or use data (you're screwed in other words ). The problem seems to be appearing mostly when the battery is low (about 20% or lower)
While this problem doesn't seem to be getting solved any time soon, I would like to suggest to those who want to have a functional phone (by that I mean make calls), but still want to have a smooth Kit Kat experience, to look for older builds of their favourite ROMs. Basically all ROMs on 4.4.3, do not suffer from that issue that much. You will hardly notice it!
Me, personally I am using Liquid Smooth v3.1 2014-06-14 build, and I have never missed a call, or was unable to make one. I can also confirm that older nightlies of CM do not lose signal as well(2014-06-17 for example)!
I don't know while this particular issue hasn't be solved yet, but I bet our great developers will find a way to eliminate it eventually!

I am very grateful for your post, because I also noticed this issue and it's driving me crazy for a few weeks. I tested almost all available ROM 4.4.4 and everywhere was the same! I did so: clean install + iodak kernel v10 + about 6%/10% battery (no gapps).
When you first start, after a reboot and enter the PIN code to establish a connection with the network was easy and fast in any case. Then I use the "QUICK SETTINGS" - switch, to change
"Network mode" (2G | 3G | 2G+3G). The network was disconnected in order to connect again in a different mode. Unfortunately again, and sometimes third or fourth (at intervals of tens of seconds) could no longer connect. The worst was the last CM11-NIGHTLY: when you disconnect the network, you can not get connected network again, at 4% battery!!!
Only connect the charger meant that after a few seconds the network connection (whether of 2G or 3G) was possible.
I thought it was fault of my device.
Downgrading to 4.4.3 is a good idea. What do you think about LS-KK-v3.1-2014-07-02-p880.zip?
Is there this Signal Issues? Now, I'll test it.

I've already tested it, and it had serious signal issues.

It's funny, but after much testing, it seems to me that the solution is in "the middle of the road":
(3) - LS-KK-v3.1-2014-07-02-p880.zip - (last, no T2FS) loses connection to the network for no reason at a level below 20% of the battery, but it is able to establish connection to the network, but after a while it loses again. Sorry... disqualification.
(1) - LS-KK-v3.1-2014-06-14-p880.zip - In my opinion the disqualification too. Switch (3G/2G) in the "QUICK SETTINGS" does not switch, but only shows what is set as the "Preferred network type" in the settings. After using the "switch" network is disconnected, but again reconnect never occurs at the level of the battery 8% and below.
(2) LS-KK-v3.1-2014-06-23-p880.zip - as in (1), but the switch (2G/3G) works good, and can freely switch the connection types, up to 8% of the battery . Below this value, you will not be able to connect to any network (unless you connect the charger).
Corrigendum: after a few minutes, joined the 2G network at 5% battery. :good:
