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.

[Q] Wi-Fi Woes

Ok I have a very iritating problem.
My captivate works amazing in all ways... except one. When I'm at home connected to Wifi, within a few mins of me putting the phone down, or even mid use, the wifi will just stop working. The icon still shows it to be connected however no apps are able to actually get internet. A quick pulldown of the quick access menu and tapping wifi off and back on again gets it going great... for another 5 mins. Then the same thing happens.
Its been like this ever since I got the phone, even after flashing different roms. Now i'm running a Linksys Wireless - N router - maybe they're not playing nice?
I dont think its a hardware fault because when I serve wifi, IE the captivate is an infrastructure mode access point for 3g, it stays on consistently and my laptop can tether for 2 hours or more.
Anyone know what might be causing this?
Thanks

When you have wifi on, go to menu settings and 'Wireless and network'. In Wi-Fi settings you can change the Wi-Fi timeout.

Try goin to settings->wireless and networks-> wifi settings (menu key)advanced and set the sleeping policy to never

I've done that...
i *Think* i've fixed it. I was using WPA2 IPK encryption or whatever.. Switched back to the 64 bit crappy WEP. Wifi was on all night and all morning with no cut out.
Might be just another linksys-is-crap situation.

HI, I figured I keep my wifi woes within a singe thread so.
I have an old D Link WBS 2310 router.
I recently got a message from AT&T that I'm near my data limit. This surprised me as my last cycle I barely got near 500mb. Since my bill isn't ready yet, I can't see exactly what it is I'm doing to use so much data.
TO be safe I figured I'd pull out my old router and set it up. After hours of hassle getting it to work on my new computer, I wasn't able to get my Captivate to hook up to it.
My laptop works fine. It gets a fast wifi signal, but my phone just says "Obtaining IP address" for a while and then gives up.
My phone gets wifi at work, at friends', at coffee shops - but not at home.
I've tried this with no encryption, WEP encryption and WPA2 encryption.
Each time my laptop would hook up to the wifi but my phone wouldn't.
I searched some other forums and found similar problems with HTC phones.
Some answers say that D Link sucks. But that answer applies to other brands as well.
Do I need "n" wifi, rather than "g"?
I don't want to buy another router only to find it still doesn't work.
Any help?

part of the IEEE 802.11n standard is backward compatibility with all previous 802.11 standards IIRC, so there should be no need to buy a new n device.
HOWEVER, i am also having issues with my wi-fi and my g capable router. i will meddle around with some phone and router settings to see if i can fix this, this is one area were i can actually be of some use on this forum

Hi. It turned out the wifi was broken on my captivate. I reset it to stock and it's all better. It had been working up to the previous day so I assumed that it was still working. The router goes down intermittently in general, so I've ordered a new one to see what's up.

Hi, I'm back! So after resetting the phone and getting wifi to actually connect (rather than being stuck searching for IP address), I'm now having the exact same problem is the OP. The OP seems to have solved this by switching to WEP. I tried this and it doesn't work. My timeout is set to never. Also, it's the same at home (I replaced my router) as well as at Starbucks and a friends house.
I'm connected, but can't download or sync. It works initially and then stops, and then comes back in briefly and then stops, all the while "connected." Sometimes I can fix it temporarily by turning off wifi and then turning it back on.
SO what's the deal? Is it a hardware problem? Is there some secret magic code?
edit: Just disabled encryption - same problem.

[Q] Am I the only one experiencing these 2 issues in regards to WiFi

Having had my LG 2x for a bout a week now I have come to find that it suffers from 2 issues I find annoying, and bordering to simply slack in making from the side of LG. Issues such as those should simply NOT excist on a phone such as this one :/
1:
I use my WiFi at home but sometimes I see that I am NOT connected to it and go into WiFi settings only to find that it says my network is "Disabled". How has it become disables, and why is the questions I would like to ask. I would like to know what causes the phone to think that.
Again my former phone was an HTC Desire and it used and connected to my WIFi network without any problems or issues leading me to suspet that this error is simply caused by LG either by fault in the hardware or a bad software that they released their phone with.....
2:
Sometimes if WiFi is actually enabled I will not be allowed to toggle on regular mobile data. The phone replies with the message "WiFi Connection open, cant open Mobile data" or something of that sort. I have gotten that message a few times over the last week and it comes regardless of whether or not my phone is actually connected to a WiFi Network or not.
Which basiclaly means that I cant use mobile data without first disabling my WiFi, reenabling mobile data and then reenable WiFi and then it works again.... for the time being.
Sometimes the phone also just disables mobile data on its own meaning I cant get any data connection unless I do the procedure above again. Its simply annoying and something that just shouldnt happen on a phone of this caliber . And with that comment I mean both the issues, because its simply not supposed to hapen for a phone in this price range or of this caliber.
All in all it seems more like LG cutting corners to be the first ones to release a Tegra2 phone. Cutting corners meaning that we have to content with a phone full of errors and bugs

I am having the same Wifi issue, it disconnects for no reason.
Hopefully this will get fixed soon in a 2.3 update. This minor wifi bug does not irritate me that much, the phone otherwise is a beast.

I had the same problem. It was caused by the wireless security/encryption method used in my router. I changed it from WPA2 Personal to WPA2 Personal Mixed, and now the router no longer disconnects my phone from the Wi-Fi. So try that.
You could disable the router wireless security entirely just to test ...

Well, I never leave the 3G connection on if I dont use it, so I can't answer you there. But Wi-Fi have greater priority than 3G. This means that enabling the 3G connection when having the Wi-Fi on and connected does not do anything. The 3G connection will only connect when the Wi-Fi is disabled.
It was the same on my former HTC Desire.

Sorry if I am a bit blunt. But that security setting has worked up till the point where I got my LG 2x, it works between all my laptops, on my SE G900, and worked flawlessly when I had my Desire, ie then its LG's issue and they just need to fix it.
IMO I can live with it getting tits up once in a while, AS LONG as it is fixed when LG releases Gingerbread. LG should however be asked why the phone "disables" the connection.
But I just checked my AP and its present setting is WPA2/WPA Mixed Mode. And the other "options" I have is: WPA2 Personal, WPA Personal, WPA2/WPA Enterprise Mixed Mode, WPA2 Enterprise, WPA Enterprise, WEP, RADIUS and Disabled.

I think you misunderstood me there . WiFi is turned on, but NOT connected, ie it should default to 3G data. But if I click my icon to turn on 3G data I just get told that it can't because WiFi is active, which it isn't since its not connected to any Access Point.
When I leaves my apartment I leave my Wifi on, and the second I leave the reception area of my AP the phone automatically switch to 3G data and back to WiFi again when I return. And thus I tend to keep both "on" to allow that seamless transition. In effect I could technically just disable my WiFi and stay on 3G considering I have a 25 Gig limit, but using my WiFi at home is just so much faster

I have the "disabled" status occasionally on my phone. It's triggered by 3 unsuccessful login attempts to the AP. This can happen if you're on the very edge of WiFi range but not sure that applies in your situation.

Well it might be that error that I am falling for then, but its just strange that the LG stalls, while my HTC Desire didn't seem to care and just grabbed the connection.
I wonder if there is some way to change it to try like 100 times or just completely ignore the limit and keep trying till it gets through.

I just had the "Disabled" issue again while sitting at home and being what 2 feet from the APN, so its certainly NOT a range issue :/
Hopefully this gets fixed with Gingerbread or I might go looking for another phone.

i have this problem with my folio and my 2x....
disabling wifi and enabling wifi helps.
for my folio i can say its a screen sleep issue(something messing with wifi as well,no solution afaik).
so if im downloading stuff and the screen goes to sleep my download stopps.
sometimes it resumes after wakeup, and wifi works fine, sometimes not.
for my folio the solution was to use the dockingstation, couse then it changes to a clock, and the screen doesnt time out.
today at work i was downloading stuff over my 2x, and expierienced the same strange behavior.
dont really know if its related(both tegra2 devices so it could be), but the occurance is too similar.

In publishing [ ] is used to insert words required for context....

Well disabling security will do me no good at all considering I dont want to leave my wireless network sitting open like leaving my house unlocked.
So no thats not really an option... sorry :/

Of course not, but have to tried? My earlier, and now, is that your problem may be caused by the security on your router. It was a problem I experienced.

I have not tried yet. Because if i turn off the security and my phone then stays connected then its not a solution >_<. Its still an issue that the phone is causing.
BUT that said I would need to leave the security off my wireless for at least a week in order to really get any reliable data on whether or not its the security setting in the router that causes the issue (But I think rather not when all other phones has no problem with it). And sorry to say this, but im not leaving my internet open for a week to determine whether or not disabling my security makes my phone able to stay connected.
My HTC Desire could get connected and never disabled WiFi on it self. And the LG 2x does it. Ergo it must be an issue on the phone when it is the only phone in and around me that causes that issue.

have you tried changing the pw to a shorter one? in the shop where i work, some devices have problems with long passwords. some just connect to the router with the 10 char pw. connecting to the other router(20char pw) is sometimes a problem. the two routers are the same modell.
EDIT just tried it with the optimus, both router work, so this wont be an solution. sorry

[Q] Major wifi problem

I have a major problem with wifi on GingerDX & stock kernel, it drops the connection everytime it is idle, and it many times doesn't come back by itself or the statusbar shows it is connected, but there is no connection, and in these cases i have to switch it off and on. There is no encryption on the router. I set the wifi sleep policy to never. This doesn't happen on stock ROM. Any solution to this?

Set the WiFi sleep policy to "Never" to avoid WiFi going "ZZzzzzzz" when the phone is idle (lockscreen kicks in)

I mentioned that i already did that.
And it does it too when it is awake... i already downloaded many apps to keep the wifi awake but no success.

In this case it would rather seem you have a compatibility problem between the ROM and your Access Point / Router.
Try switching channels or secure your network to rule out your problem comes from tons of strangers using your wifi.

I think i switched channels before, and no success. The router doesn't accept connections from unregistered devices so even without password, nobody can connect from outside.

LOOOL ... MAC addresses are sniffed in a matter of split-seconds.
Anyway, since you are certain you already did everything in the book, and outside the book ... maybe try changing your WLAN cable past a new one.

There is no WLAN cable on the router, the antenna is connected directly to it. By the way 2 computers are connected through wifi and their connection is constant. But if it works on stock rom then there is something in the rom itself.

I suggest edit twilan.ini to make N standard work. This solved my wifi problems on SDE .
Search XDA for n standard on x8
Sent from my E15i using XDA

I'm gonna test it for some time, I will report back if it worked or not.

I have similar problem myself as well. I even upgrade it to latest rom and it still does that. I already set wifi sleep policy to NEVER yet the damn thing could randomly decide to cut off. As soon as I wake the phone up it will re-establish connection. Ever single time. Why does it not try to re-establish connection while the screen is off? The funny thing is that I have no idea when it drops connection. The logging has no time stamp that I could track down events.
I believe sincerely that there's still some bugs to be rid of

Try enabling N standard, since i enabled it the wifi stays connected, for now.

i had the same problem.. U just have to use nAa or Alfs for cm7 kernel and rom which works with these kernels and no problems anymore

Wifi doesn't connect well

Is anyone else having issues with wifi connecting? My issue is that wifi doesn't always connect, and the only way I can usually get it to connect is to restart my phone. So I have my home wifi saved in the phone and when I leave it obviously disconnects, then when I'm back home I have to restart my phone in order to get it to connect. My work wifi has even more issues and it doesn't always connect from a restart. Is anyone having this issue?

Yup see my post in this forum, i have issues with my home cisco ap. I need to use a wifi fixer app just to stay connected.
Sent from my XT1254 using XDA Free mobile app

Mine has worked perfect so far. Have connected to several networks while at home or working.

Mine is working great too. I am getting better signal than my Razr M, and compared to several other phones I have owned, the M got wonderful signal!
I got it in red just in case anyone is curious. Most complaints I have seen seem to come from those with ballistic nylon, which was the deciding factor in buying it in red.

Magnum , which app do you use? i'd like to try it. But honestly at this point I think I'm swapping out the device...I don't see anyone else that has this same issue as me where I have to restart for the wifi to work. I did a factory reset and thought it fixed it but nope it disconnected grrrrrrrr. Luckily we can swap out within 14 days.
Oh and mine is red too and I still have issues

I am so sad. I factory reset, didn't help. I went to Verizon store and swapped out for a new phone. It connected to a random wifi by the store so I thought woohoo it works. It connected at home. Then I got to work today and its having the issues again. It won't connect unless I restart the phone (and even sometimes restarting doesn't help). I'm at a loss. I'm so sad because this is the only phone that I want that is out right now but if wifi doesn't work then it is completely and utterly usesless to me. My only glimmer of hope is that the case (verizon one that has the kickstand and the belt clip) is making the wifi act all wonky, so I took the case off and lets see what happens. Fingers crossed!

Did you disable the "Avoid poor connections" option? I found it wouldn't let me connect to a lot of networks on my old Razr M, so I disabled it immediately when I got this phone.

These are my settings, and I haven't had a problem.

Sorry to bring this back from the dead, but it appears to have resolved a weird issue I was seeing. Specifcally, I would see "old" Wifi SSIDs in the list that were not available anywhere near me. For example, I just traveled 3 hours away, and I was still seeing a router from the 3-hour-distant site. Only the phone saw it... my computer, for example, confirms it's not real. It would just show up as a "ghost" in the list, and never disappear.
I checked the post you had, and saw that I had disabled most of the items... except "Wifi Notifications" and "Scanning always available". So, when I disabled those, and then turned off/on the wifi, the ghost SSIDs disappeared.
In related news, this issue may also causing one of the routers I used to always show "Saved, secured with WEP" and yet it would never connect. It was a real signal in the area, and my laptop connected with no issues... but the phone would refuse to connect, even if I forgot the network and reconnected with the WEP key, etc. I'm hoping this fix (disabling the above two items) will fix that as well... but I won't know for sure as I'm 3 hours away from that router now
In any case, thanks for the posted pic... it helped me identify and fix the problem... hopefully this can help others, too!
