3g vs. wifi conflict

As we all know meanwhile, there seem to be different bugs that all drop the connection.

1) One very common bug for Cm7/9/10 seems to happen when 3g is used together with wifi

2) The more strange bug may happen anywhere, and at any time, but usually, if it tries to connect to a new tower or with a different connection type. Since it is reported that CM10 network settings are not consistent against *#*#4636#*#* settings, and are not persistent at all in such cases, suddenly switching to auto 2g/3g while still claiming to be on other settings in the system options, it may, but don't have to be the same bug, together with a strange new one.

Bug type 1 is as old as CM is, I faced it on the White Rabbit Editions of CM7.1 and 7.2, on CM10, and even on CM7.0 whare at least bug type 2 seemed to be fairly unknown until end of november 2011. I tried nightly builds from october and november 2011. Both are very stable against bug type 2, but wifi together with 3g, especially if coming from flightmode in the morning, still may kill the connection deeply.

So I just tried out one of the latest MIUI builds, where this kind of bug seems to be very unknown, although it is based on CM7. I tried and observed... and noticed a funny thing that may explain, why MIUI could be that far more stable than the rest of CM7: It never ever runs 3g together with wifi, so it should be able to prevent most cases of bug type 1. While connecting to wifi, an I guess it really happens before wifi is fully established, it drops the 3g connection, just to reconnect on 2g a second later. It really looks like a complete drop, and not just like switching. If this is a stable implementation, this prevents lots of trouble right from the start.

If you face bug type 1 alot, you might want to try out apps that act similar. I know that you can configure tasker to do this trick, and there is a CM-only app called "2g auto toggle (Cyanogenmod)" that seems to be able to do the same. Since I have no idea, how this is managed in miui, it may be more stable there or it may be the same method. But I think it is worth a try anyway.

@ atma_weapon

To not confuse you too much:

9_24 is the latest defy-only release of CM10, correct.

From there on quarx managed to flash a custom kernel too as 2ndInit boot which means that there are newer releases in a new folder, named 2ndInit-Releases for Defy(+) which have the 526 in their name but fit to ALL defy (525) and defy+ (526) devices the same, by flashing a 526 kernel together with the rom. Of course the new kernel is not as stable yet as the original one, but those roms are pretty fast.

Right: With those roms, your 525 becomes a 526. :eek:

And yes, this may be reverted using the backup/restore of 2ndInit recovery.

Data Dropping on Plex, BBC iplayer and Skifta etc

Hi

I'm using Quarx 09/11 build on a red lens defy (mb525) and everything is working exceptionally well but for a massive silent hang when one attempts to use any of the following; Plex, BBC iplayer and Skifta

I say silent because there is no indication that the data connection has crashed, but in order to surf after starting these apps the wifi needs to be reset (toggled off/on).

I know there are a lot of threads about this and I had a problem with wifi a few builds again which I fixed y removing wireless n from a config file (can't recall but will provide details if important).

Is this a similar fix, or is it something related to multicast and/or ports which require a little more structural changes in the build. In short can I fix it or is it an upstream (quarx) build issue.

Thanks

I am not very active even if i am reading your posts since 2010... as many of us, i am facing connectivity problems and after hundreds of test, rom reset, etc i did not fixed it but i found that the YouTube standard (i mean from google) application is NOT facing connectivity problems.

I mean that even when i am updating an apk from google at only 32kbit/s and I can simultaneously watch videos on YouTube without any lag nor connection problem (and still slowly download the updated package).

I have flashed many version of our CM9/10 roms and it is still the same, good speed for few hours, and then after that a poor 32kbit/s EXCEPT for Youtube.

Can some other users confirm that unusual behaviour ? If so, many someone with the right skill could find why and then fix our problem :highfive:

In Cm7 latest builds by Maniac103 you are announced if a ril problem appears while in other builds a reboot its done without you know. Those reboots I've experienced them even in stock Rom.

[Defy Q&A, Help & Troubleshooting] cyphomatic:
I am getting really confused with this problem

I have 2 Defy's: One Defy red lens and one Defy+.

Both have CM10, latest december version from Quarx installed.

Defy, red lens:

Before

I had CM7 on the Defy wich was quite stable. With 50+ apps it became laggy and used a lot of battery.

After

: ICS is working nearly perfect. It lags with chrome and google now (keyboard swiftkey) and sometimes Trebuchet. It looses connectivity only 1-2 times a day. Weirdly it's mostly at home at the end of the day (+-18u). During the night and deep sleep, no problems. So far so 'good'. The loss of connectivity I almost take for granted since I love ICS above CM7.

Now My Defy+ is (still) getting me a headache

Before

: stock rom on Defy+, version vodaphone Germany (rebooted many times daily with no reason and instantly rebooted when making 2g//3g connections). I had to keep all mobile networks off to keep it alive for +-2hours before next reboot. This was a problem wich many defy+ users encountered. Advice from motorola was the get another SIM-card. This seemed to help a lot of other people effectivly. I tried all the possible SIM's availible in my country, wich didn't matter. The phone was produced to work with German Vodaphone SIM-types. Altough I bought it simlock-free on a dutch webshop. (should have taken my money back, but tought I would fix it :silly:.)

Now

with ICS: After reboot, the phone stays alive :good:. I also can make mobile network connections without crashing :cyclops:.

BUT, and here it begins, it looses

all connectivity

after a few random hours. It has no reception whatsoever. When I do make a call, the call aplication doesn't shut down anymore. No internet, no call reception is availible. After manual reboot, the problem is gone again and mobile networks and calls are possible again.

I tried othor basebands, without succes. My network (Belgium) is on 900 and 1800 Mhz. There is no selection in the list that has the exact same frequency. The is only central europe 3.4.x, wich practicly works fine on the Defy red lens.

Altough I don't believe that is the problem. Because my Defy red lens works (almost) fine. So the problem should be somewere in the difference from the drivers/hardware from the Defy+. There were the stock rom just crashed or reset itself, CM10 just ignores the problem.

I used the stock to travel daily to the city. So managing cell-towers and signals weren't always cousing the problem. Switching to 2g only didn't matter at all. Switching mobile connections off, still coused to lose call reception.

My idea:

My idea is that there are many differences in production of the Defy(+). Especially with handeling the SIM-cards to connect to (mobile) networks. Specific provider-made types of SIM-slots are what I believe the key to solve the problem. There must be a solution in the driver/kernel to handle this. Somewhere in the system there is probebly a time-out function that has to be corrected wich should reset the connection without having to manually reboot the full system.

Hi cyrusct82,

after installing the files from test_ril.zip the data connectivity drops occurred much less frequently. However, since I installed these files my battery usage has gone crazy. The phone lasts about 10 hours now. Log says the Wifi signal is eating up the juice almost completely.

The stupid thing is that I did not back-up the original files when installing test_ril.zip. Do you or anynoe else here have the originals and could upload them? Would be a great help to me.

I myself had to change carrier because of problems. I had a virtual provider, and one day my DEFY started showing "out of service" messages. I could only get signal on 2G, 3G was showing that message. No matter what I tried it would not work consistently on 3G, while it was working perfectly on my girlfriends cheap ZTE phone. Conclusion: the RIL on the DEFY is buggy, and there is nothing we can do about it since it is a closed source binary blob from Motorola. The only thing we can do is to change to another carrier,, just as I did. I have proper signal and data now with no drops whatsoever. I know it is disappointing, but we can thank Motorola for those RIL bugs.
