WiFi App interference?

Is it possible for an App to interfere with the WiFi connection? I've downloaded plenty of third party, torrented apps and I've been noticing that my WiFi will work for a few pages and then stop loading, throwing up an error saying "Web page not available" showing the little Android. This would cause me to disable WiFi and go strictly with 3G. Enabling WiFi later would help with a few more pages until it wanted to die again.
After I uninstalled ALL of my apps and unrooted the phone, I've noticed that the WiFi works again (so far at least). I still have the same 1 bar signal from across the house, but it isn't giving any more errors.
I constantly used task killer to free up memory, so I don't think those apps would have made a difference in the sense that they may have been taking up some bandwidth or the such.
Any clues guys? Thanks for any help.

Same
I have the same problem. I rooted and did the settings.db. My wifi will turn on and connect but 20-30 seconds later it just turns off on its own. I haven't unrooted it to see if it fixes it though.
How did you unroot yours?
Thanks

Like, I'm pretty sure that's just karma, dude. Harsh vibes from people like me that make software for a living reaching out and disrupting your chakra centers. And your WiFis.
That and using Task Killer in the first place. Not needed, causes more problems than it solves (and it solves almost nothing on Galaxy S).

I am in the same boat--just started noticing it today when I got home from work and turned the phone back on only to see I wasn't connected to wifi. When I connected to my network again I noticed the 3G icon stayed on the screen with the wifi connection symbol, where the wifi icon used to replace the 3g icon. After a little while, it was gone.
I have rooted and removed some of the AT&T apps but nothing else. I havent sideloaded any apps either. It usually take me a couple of tries to connect to my router (WRT54GL). Sometimes it also seems that my phone turns off wifi by itself.

I hope this isn't a symptom of the battery cover antenna. Does your WiFi signal show as weak in the strength readout?

It does actually turn off wifi by itself! I did the following last night and haven't seen an issue since. As a new user, I can't post links: androidforums.com/samsung-captivate/130163-wifi-connection-turns-off-when-sleep-mode-default.html
From androidforums.com:
By default the wi-fi setting is set to go to sleep (and use cellular data instead) when the screen is off, which will most likely happen while you are streaming music as well as other things. To change it so the wi-fi never turns off, go into the phone's menu -> wireless and network -> wi-fi settings -> tap the menu button and select advanced which has an option for wi-fi sleep policy that had been defaulted to sleep "when screen turns off". There you have the option to change it to "never" or "never when plugged in".

Did a little more playing around with it, finally had to reset my router to maintain any type of consistent connection after restarting the phone. One weird thing is that my old iPhone wasn't able to connect to the router consistently last night until the reset either--it has never had any issues in the past.
After the reset, the captivate did maintain a consistent connection--I browsed a few websites and streamed part of a show from my computer using Allshare.
This morning when I turned on the phone wifi wasn't connected so I went into the settings and looks like the phone had attempted to connect unsuccessfully. I clicked it again to connect and it connected without any issue and was fine until I left for work. The whole thing seems a little wonky, as well as it should automatically try to re-connect if it fails the first time if network is in range, or at least give you an alert.
I just set up tdogz suggestion above, so we will see if it helps.

Haha sorry bud, but after browsing for some good videos to put on the phone my curiosity made me type in "android" in the torrent search box. I was amazed I could do such things.

Before I unrooted the WiFi wouldn't work with full or low bars, not sure of the strength readout.

Running into the same issue, I am positive it is a software issue. It only seemed to happen after I flashed my phone with the Odin One click downloader. Dunno if it is coincidence or not. Going to try clearing the user data from the recovery window to see if it helps. I also notices on the power widget, i cant control GPS from there, blue tooth as well i think.

Yeah, user data reset did not do it. Reflashing now.

Huzza! I figured my issue out, may be yours as well. Did you do the sideload hack with the settings.db? Turns out you need to change the owner of settings.db to system:
Code:
# chown system settings.db
After that, I was good to go. The logic behind this is that settings.db tracks more settings than just if you can sideload apps or not. I'm betting the system is trying to change a value in that file and it cant after the hack, so various systems fail.

[Q] Streak7's bug???

--------------------------------------------------------------------------------
Do any other Streak 7 owners have this problem also?
To reproduce the problem:
Run from an area with good signal coverage (home/office)
into Subway (NYC Subway) where you find no signal.
Inside the subway, when you turn on the screen (as many people will do to kill time), the data connection will of course, finds no signal.
Then when you come out of subway again, in an open area where signals are all good, Streak 7 cannot establish a proper data connection while showing perfect full bar signal strength..
Only restart can restore the data connection. Turning on/off airplane mode wont help....
Is it just my configuration or a bug in streak 7?

I go from the street level to the red line subway in chicago but i lose 3g and hop onto 2g. I lose signal a few times until i get back in the elevated tracks and gain 3g. Not sure if it helps you but i don't have a problem with data connection in that situation. Granted, data is mostly worthless when the train is moving between stations.

Thanks so much!
I am continuing monitoring what combination will create problem.
Believe or not I have observed 3 times such issues witin the past 7 days... Hopefully they were only due to some apps, not the system defects.

sighs...
Right at the moment when I decided to keep and love this streak 7, this bug came to life again...
Today I used the streak 7 in NYC subway, and the signal bar, of course, displayed "4 grey bars with a red cross" which means no signal.
And when I get back home, it STILL DISPLAY THE SAME THING. that is after coming out of subway for 10 mins +.
Then I switched on airplane mode and switch off again, the signal bar display is
full signal, but without the 3G/4G sign , and I tried apps, all reporting no data connection.
Only solution is to restart it.
Can I figure it somewhere in kernel or software apps?
If not, I may really need to return it with 15 days of purchase =(

Similar situation happened today. My Streak showed 4g signal with full bars, tried to open a app it told me i had no internet connection. Once i closed the app the 4g signal flashed then everything was up and running.

Just wanted to let you guys know that I have had a similar issue with my Droid Incredible. If it fails to get a data signal while attempting a background sync, it will actually restart. My solution has been to put the DInc in airplane mode before I enter the subway, and then remove airplane mode when I leave. Not real a big issue, since it takes about 2 seconds to go into airplane mode (& out of it).

This problem barely happens to me now.
I just want to make sure it is not a hardware problem. As long as there is a "soft" solution to it, I am fine. =)

No incomming calls while in 3G (UMTS) Network

Hi all together.
I'm interested if someone else can confirm this Problem. Situation:
- HTC Incedible S (brand new )
- Provider: Orange Switzerland
We suddenly recognized, that it's not possible to call this phone . The caller just get's a voice-info that the "The person you have called is temporary not available. Please try later". But the other way round works perfectly, so a call-out FROM the Incredible works fine and everytime.
I did some investigations and discovered the following:
- When forcing to 2G (=GSM) the Problem disappears.
- When forcing to 3G (=UMTS) the Problem reappears - but...
- ... when at the same time "mobile data connection" is active --> Problem away!
So when i'm at my home then the WiFi-Connection automatically get's active and the "mobile data connection" get's offline. And in this situation no calls reach the phone any more. If i manually disable WiFi (and then "mobile data" get's active again): Voila, everything is ok.
Reenabling WiFi - mobile data goes off: No more incomming calls.
Disabling both WiFi and mobile data: Also no incomming calls.
It seems that the incomming-call-signaling is handled in a way that requires an active mobile-data-connection. This seems to be a little bit odd.
Thanks for any ideas or just a confimation that i'm not alone.
Oli
P.S.: Of course i called the providers hotline. But they just said that there is no problem in the net. I should try it a few days later agein. Damn...

Hmm sounds strange....
The only tip I can give currently: goto settings - WiFi & networks - mobile data. And check the mobile data always on.
It's not a real solution, but should fix it for the time being.
But it is strange... Should not happen, maybe there are some problems with there network, so keep trying for the next few days. Otherwise contact them again.

ah! I believe this is something to do with the network provider. Do you live in a place where the network coverage is midiocre? I have the same problem with the iphone 4 (with the bumper )... sometimes even I am not able to make calls... so I have to switch off my 3G! it is indeed odd coz it interupts with the wifi! Did you try doing a master reset?

Thanks for this idea, but this option was already checked. This seems to be the default, so all my tests (as described in the first post) ran under this config (e.g. "mobile-data-always-on" is checked)
Hm. Still hope for any other ideas.

No, it seems to be a pretty good UMTS-coverage. And the mobile-data-download-speed with HSPDA is really fast (1-2 MBit/s). And when i go outdoor the signal-strength (as shown on the phones display) goes up to 4-of-4-bars (100% Signal). And still: incomming calls not working.
So i think the 'physical' Network-Infrastructure is not the problem. It's obviously a netwrok-logic-problem.
Thanks a lot for your help/ideas.

Ok, some new observations.
The problem of "no incomming calls while connected through UMTS" seems to be a local problem of the network-cell/Antenna around my home.
If i'm about 500m away then the problem seems to disappear..
Of course i did not test every Antenna of Orange Switzerland
Another point: I wrote that the problem just occures when i'm booked in in UMTS AND mobile-data is inactive. That's not completly true, as my newest investigations show: The problem is also present if UMTS-mobile-data is enabled.
But it dissapears for some seconds while and shortly after there is mobile-data-traffic.
Example:
- UMTS forced (no GSM), mobile-data enabled, WiFi disabled
- Phone 'idles' some minutes, no background data-transfer
- Here the Phone can not be called
- Now i go into Android-Market, search a 'Big-App' (10-20MB) and start download
- While the download is in Progress the Phone CAN be called
- A few seconds after the download completes, the Phone still CAN be called
- But later - let's say 60 seconds - the Problem re-appears.
So it seems that an active data-transfer is like a 'heartbeat' for the Orange-Cell and the Cell registers the phone as 'online'. But when data-idle the heartbeat is missin.
I will make some more calls to the Orange Hotline

did you solve it. i don't think thats the case certainly not for me as i'm having exactly that issue of no calls while in 3g mode but if i go back to a stock rom its fine. so the reception distance/signal is identical (i.e i haven't moved anywhere) and its fine on one rom and not another so it must be software (in my case)

So, hi together.
As the original poster i can now confirm that the described problem dissapeared.
We had nothing to do - so no change of any settings nor doing any software-updates. It's simply woking again.
So i'm no pretty sure that the problem was just a local one, in exactly out network-cell. No problem of the device.
Nevertheless: Thanks all for yout infos and tipps.

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] While in Europe: Moto X won't reconnect to cell data, post-WiFi use

Hey guys/gals -
I got my Moto-X a few weeks ago, and have been using it without issue on AT&T. Unfortunately, I'm just wrapping up my first trip through Europe with this phone (left my iPhone 5 at home), and I've noticed a very odd thing over the last week.
For some reason, my phone will not re-establish a cellular data connection once it has connected to WiFi (and subsequently disconnected from WiFi). I have noticed this - consistently - in both Germany and Italy. In all cases, once WiFi is no longer connected, I can see that the cellular data network is available (the 4G or E logo shows up, grayed out, next to the cell bars) but it will not reestablish. The only way to obtain a cellular data connection is to restart the phone.
I've tried going into airplane mode; I've tried cycling cellular data. Nothing I can think to try causes the cellular network icon ("4G" or "E") to cycle from gray to white...I simply cannot get back online without a full restart. But once I've restarted it works fine - so long as I don't jump on WiFi.
The phone isn't unlocked; it's an AT&T device, with no APN tweaks.
Anyone have any idea what could cause this behavior? Unfortunately, it's going to be another four or five weeks before I'm back here to test any ideas...but I figured I'd reach out while the issue is fresh.
Cheers.

Just to chime in, I've also seen this issue on mine, but it only happens with certain WiFi access points. After using the Cisco ones at work the problem occurs, but my Asus N66U doesn't seem to upset it.
