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.

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.

H and 3G

After flashing CM6RC2 I can see that the data connection keeps switching between 3G and H, while it does this, my connection goes on and off, and I believe it's killing my battery as well.
I'm pretty sure it's not the ROM because the connection goes on and off while I was on stock. The ROM just made the difference of showing the data changing.
Is there a way I can make it go between only Edge and 3G, or just Edge and H? Like to try it that way for a few days and see how it goes.

No and no. Your connection does nothing wrong, you have data streaming - that's why you see H coming on. If you want to save your battery - look for the application that pulls the data constantly. HSDPA is extension of UMTS (3G), it works when you're connected 3G.

Can you give me an example of "pulling data constantly"? Like setting up Twitter to check for updates every 15 min?
Everytime my battery goes low and I check usage, the top two are Display and Cell Standby, with Display having a huge lead.

That's what you're going to have. Your battery status looks ok.
Example - setting a widget to update every minute, or setting a widget to update when it can't access whatever it needs to access. Also, if I'm not mistaken, data usage shows as a part of "Voice calls" or "Phone idle", and not as a part of "Cell standby" or "Display". I'll try to verify it later today.

Now this is curious to me, I just recently unlocked/rooted and flashed to CM6 RC1, on a Nexus One. I'm on a ATT Microcell and previous to root always had 3G at pretty constant speeds around 1.5/1.6 Mbps. Since flashing I see the H i'm guessing probably 60/70% of the time and after looking at the DalviK Debug Monitor Logs i'm pretty sure I know what widgets/apps are keeping the data connection alive. The thing is though when the H is displayed the highest speeds I see using the Speedtest app are around 0.2/0.3 Mbps which seems pretty lousy. If I go to *#*#info#*#* and click WCDMA only I seem to lose my connection altogether, although I didn't leave it there long. I'd like to go back to 3G only but not sure how to go about this, it was never an issue before root/flash, and I really like The Cyanogen Mod, my device is more stable now then when I was running stock 2.2 FRF91. Any ideas? or am I stuck with this situation until I flash something else, or go back to stock (ain't gonna happen, the stock thing).

Cyan ROMs automatically set your build prop file hsxpa to 1, but stock value is 2. This probably is limiting your speed. I know it caps my upload speed to 0.3 Mbps so I edit the value back to stock of 2.

BTW, if this thread is still up - I've checked, and the data (at least when I tether) falls under "Voice calls" category.

Is it possible to adjust build.prop to only use H and Edge?

what you are seeing is the way the microcell works, i think it only operates at a certain frequency and registers with the phone at whatever rate is displayed when the cyanogen icon is displayed for 3g, the slower data speed is because the microcell uses your own internet pipe when you use data from the cell

nope to both!

Always on hspda?

Is there a way to force the phone to always be on hspda?
Normally it would switch back to umts after like 2 seconds after being done transferring data.
I read a lot of comics, and switching between comics takes a few seconds every time because it needs to switch from umts to hspda. When it for some reason already is using hspda it loads the next comic in a second. So it can save quite some time if you read comics a lot.
Also will it significantly drain more battery? I will of course set it back to standard when I don't use my phone.
Thanks in advance.

No you can't. It's the network that switches you over, not the phone.

Okay. Thanks for the quick and helpful answer.

is there a way to force a faster switch from umts to hsdpa?
when i hit a link in my browser i notice that it takes 3-10 seconds before umts switches to hsdpa.

The only thing you could do is have something constantly using the data connection so it never drops back to basic 3G.

You can set your phone to only use an hsdpa/umts connection by dialing *#*#4636#*#* and chosing WCDMA Only in the Phone Info section.
Edit: whoops didn't really read the OP. this doesnt help

You're right, I guess running a ping command from a terminal client will do just that. Atm I'm on gprs only since I'm home, but it seems to keep the data connection busy while it runs in the background.

To the battery thing: yes, it'll drain the battery much faster.

[Q] HD7 Data Connection Issues (T-Mobile USA)

Has anyone else had trouble with loading web pages occassionally on T-Mobile's data connection?
Every once in awhile, web pages simply won't load, and I get the "This Page Cannot Be Displayed" error. It seems like I have to close all my tabs and then open a page to get it working again. This "glitch" or whatever it is, doesn't happen on WiFi, but has happened numerous times on the data connection.
Is this happening to anyone else??? It's like T-Mobile is trying to throttle the connection or something... I haven't used THAT much data

I have noticed this too, but when I look I usually have dropped to Edge from 3G. I think it has more to do with the 3G signal than the device itself. Possibly issues with your location the construction of the building you are in overhead fluorescent light, all of those might factor into the dropping signal. Just a theory.

I was pulling some CRAZY download speeds on mobile speed test website.
I was actually getting 25 Mb down consistently... With a 7 Mb sample size and about 5 different tests on 3G! The phone was blazing fast at the time too.
When I got home on wifi my speeds were back to normal - around 9 Mb.
I wonder if they were doing some network upgrades in Princeton NJ today?
Pretty crazy, and while it may have been the speed test was whacky, I really don't think it could've have been wrong on that many separate tests.
Anyway, that's my input. I think data has been good.

Yea, speed is no issue. I get 9 or 10 Mbps download speeds regularly. The problem is as I described, once in a while pages simply refuse to load, and I basically have to restart the browser. You have never experienced that? Thanks to the other user for your feedback, that might be true about it switching from 3G to Edge, I'll try to pay attention to that the next time it happens.

yeah, i got the issue you mentioned earlier this afternoon. hitting the refresh button doesn't seem to help either.

On several occasions, I've struggled to get a decent data connection, despite there being an apparent signal. Turning the data off and back on again in settings->mobile network has fixed it, but it is frustrating.

Yep. well it's good to know that others are experiencing it. I don't believe it is a problem with T-Mobile's network, since my old WinMo phone worked just fine. I wonder if people on ATT have this issue, cause I would say it is something that needs to be fixed in Windows Phone in general. I'll post the question in their Samsung Focus forums.

I usually do not have any problems with the data on my device.
But one thing I have noticed that is happening frequently on my phone was... It gets stuck in 'G' (which I think is GPRS, worst than Edge). After a bit of analysis, I have realized, that when I get into and out of a tunnel (I take a subway to work), at times, my device does not get the 3G and stuck in G.
But once I reboot the phone, I am back to full signal.
Again, this DOES NOT always happen. Only once in a while.
On the whole I am actually VERY HAPPY with the data speeds. I was actually amazed to see how Netflix app was streaming movies seamlessly on my device with out any hiccups even while passing through areas where the coverage fluctuates from 3G to Edge and back.

hi all, I have the following problem: buy a t-mobile hd7 released, I need to manually configure the 3G connection and I have that option. I live in Argentina and so far with my previous phones had no problems (hd2 htc, htc desire, xperia x10) thanks

I have noticed this issue too and I don't think it's t-mobile but on a positive note the web pages load up very fast.

[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.
