My captivate has a problem. It'll connect to WiFi no problem. Unfortunatly, after a while (could be anywhere from long 30 seconds to a few minutes) the WiFi stops sending data. I have to disable/reenable wifi to get it to work again. It still says connected to network, it just won't receive data.
Anyone know of this happening, have a fix, or maybe what I should look for that might be causing this issue?
I disabled recently installed running apps, no help.
I did try a speedfix last night, and it was unsuccessful, and I uninstalled it. Didn't test enough after that to know for sure if it was the issue, but I don't think so.
It was like, I was going through google reader, started a youtube vid, paused it, restarted it, and it wasn't loading. Just wouldn't load. That's when I think the problem started, and I haven't installed anything since then, that i haven't disabled/uninstalled.
Have you tried flashing the stock OS. Maybe this will help. My wifi has been solid so far but i will see if i get a problem like yours. Try reflashing. If it doesn't work post back.

I have the exact same issue on enterprise class cisco wifi APs. The only difference is the symptom is immediate, and not after an interval of time.

I'm thinking of this, but I don't know...
I have my music on my computer, I have my .apk's in a folder and my market synced with appbrain. Anything else I need to do? Will appbrain reset, and make me go find and reinstall everything?
What about the apps that I paid for, what happens to them?
Would be my first flash, and I'm thinking about flashing one of those I9000 roms, but that would be a last ditch effort. I really hope to avoid this.

It's an AT&T U-verse router, and only started a few hours ago, as near as I can tell.
I experience the same phenomenon of dropped wifi, and it occurs at any AP, but I have an interesting twist.
One time out of twenty when I start wifi, the 3g icon doesn't go away, but stays up on the status line with my wifi icon. On those rare occasions, my wifi stays solid for days. Unfortunately, it's random and rare.
same issue
My Wifi stops sending data and the 3G still shows. Sometimes restarting the router helps and sometimes nothing helps.
For anyone that might find this later, turns out (after two rom flashes) it was the router. I found this out when connecting my laptop to it. Surprised the captivate didn't admit it lost connection though.
I wish that were the case for me. My Captivate stays connected, but stops receiving at many different APs--Home, Starbucks, airport. I need a solution or a Scotch.

I had this exact problem, I tried a factory reset and it was still broken. I exchanged my phone and now it works perfectly holding a signal (except for enterprise 802.1x ap's which are known to be broken). (Also if you run dd-wrt check your logs for "deauthenticated due to local deauth", there is a problem with the wpa/wpa2 modules in either android or dd-wrt that they are not compatible with each other).
I actually found this searching for a solution to my own issue with WiFi. I actually fixed it while I was reading this. Unfortunately I have AT&T DSL with 2wire Modem. I went into the setting and setup MAC filtering and assigned it it's own IP. It has worked flawlessly for the past hour. I know this probably will not help when at other locations but at least at home I have a good connection.

Same router type as mine that lost it originally. Interesting, wonder if there is a connection? Or random coincidence.
I'm having a wifi issue as well, but not to the extent others have.
I connect fine, but it appears as though my data download speed is capped at <2mbps for both wifi and 3g?
My wife's iPhone is getting download speeds of over 10mbps on the same wifi network and >3mbps over 3g.
Is it worth flashing back to stock? or is this a known issue?
I'm running stock JH3 with SRE 1.2.1a with lagfix
I have this same issue and it's really random. Running JH2, sometimes it works on wifi, sometimes it doesn't. Sometimes disabling\re-enabling wifi fixes it, but rebooting the phone always fixes it. Really frustrating...
Ever since I got my Captivate, it has had issues with wifi. It's not my routers, or any configuration in my routers, as it happens with 3 different routers (not to mention that I work in IT, so it's definitely not the routers).
Here's what it does. When you start with a fresh boot, it works perfectly fine. As the day goes on, it gets worse; it starts dropping the connection randomly, and eventually stops working altogether. This wouldn't be so bad of a problem, but the point that it "tries" to start accessing a wifi AP, it drags the phone down in speed, eventually freezing, causing me to ave to reboot the device.
I already tried all options with wifi sleep policy; I've tried 3 different ROMs; I've tried clearing all wifi settings and letting the ROM generate a new .conf file, I've tried different wifi firmwares. Nothing works as it should.
What should I do now? Does anyone have any tips for me? I know it's the OS and not the phone, because the last ROM that worked perfectly was Perception 4.
Thanks for the help.
Easy fix I found.
Open Allshare, it should have come pre-installed.
Connect.
Your Wi-Fi problem should be fixed.
You will have to repeat this step when switching between locations, or when you come back to the troublesome router. I don't know why this works, but it does. It seems to have helped alot of other users in other forums with this problem. Maybe someone should make a sticky of this...seems to be a big problem with 2.2 Foryo.
Similar experiece with both an EVO and Captivate with a Linksys router and DLink wireless AP. Whenever I walked into the house, the other PCs attached to the router would stop working, the phone would not get data although it showed as connected and I had to reboot the router - both wired and wireless clients. The Linksys was a very old firmware and I had bad experieces with flashing a few previous devices. I ditched my Linksys for a DLink 8 port and wireless and have not had the issue with either the EVO, Captivate nor any devices attached to my network.

This is news to me. You are correct, I do have Allshare. I'll try it the next time I have the issue.
What if I simply remove Allshare? Will that fix the problem?

I have 2 Linksys routers with the latest firmwares, and one D-Link. No matter, it does the same thing with them all.
I should also mentioned that I already tested with changing the router's wireless broadcast channels, signal strengths, firmware updates, the whole 9 yards. The problem is the phone, not the networking equipment.
I used this on 3 Captivates in our house and they are all working great now. Had F&*%%#ed wifi issues before that. They are all ok now. Hope it lasts!

I'm not sure if that will work. I don't think this is by any means a permanent fix, but a temporary work-around. I think it just kicks the wi-fi into gear again somehow...=-(
Hope it helps someone out though.
I had a friend who was having issues with her phone not even attempting to scan for wireless, seems there is an issue on android phones that the networking cache file or whatever it is gets cluttered and needs to be renamed. (Android recreates it)
The process is rather simple, I walked my friend through the steps over the phone w/o issues.
I had her use oneclick root/unroot to root her phone.
http://forum.xda-developers.com/showthread.php?t=739304
Then Had her go through these steps to rename the file.
http://androidforums.com/samsung-moment/46179-unable-scan-networks.html
The steps are for a samsung moment but still work. Also noted that the steps w/o rooting do not work. After you finish renaming the file you can use the application in the first link to unroot the phone and go back to stock
SlappyMcgee seems to have the best fix
It wont hurt anything and I suggest just renaming the file to .old instead of deleting it. the entire process takes like 8 mins

Link doesn't work, at least for me.
Update:
The Allshare thing works. The problem is that it's not a feasible workaround, because you have to keep doing that every time you want to restart the wifi after the screen goes to sleep or what not.
I will next try that config file delete. I read up on that last night, but didn't think that was it, because I already did a few ROM installs which didn't seem to clear it up.

Little early for me to say this is working for sure. But ill be damned if it didn't, at the very least, temporarily fix it. Instant reconnect. Doesn't hang. Seems like it might be the real deal, for me at least. Ill come complain if it craps out again.
Edit: .... worked for 15 minutes. Aka doesn't work...

I tried all different ones. Firebird and Speedmod mainly. When I flash newer versions, I always wait till the battery is 100%, and I clear the Dalvik cache. Nothing ever works.

i had wifi issues and still do. my girlfried does too with her Aria. The phone really seems to only work on routers who have a DNS set to google. The bar near my house it flys and at home i was getting no wifi so I changed my router DNS to google from comcast and its fine. I agree there is a problem but not one that is going to get fixed by Google
My wifi workaround
I had two captivates which both had problems with my home router. Reseting the router never fixed the issue, but resetting the phone did, at least for a few minutes.
I found that phone has problems using DHCP with routers that assign addresses in the 192.168.1.xxx range. It seems to be a conflict with some other internal IP in the Captivate or something. To get around this problem, I had to change the local address of my router to 192.168.2.1, and change the DHCP range to 192.168.2.xxx The new subnet cleared up the problem immediately for me and it hasn't returned, at least, not on my home router. Unfortunately, this won't work on hotspots or other networks that are stuck in the 192.168.1.xxx range.

I ran into this problem on my Router. Netgear wndr3700. For some reason when I turned the wifi on my phone either the router was assigning it the same address as my Tivo or my phone wasnt accepting anything but that address. To resolve I forgot the connection my phone then reflashed the firmware on my router. Then reconfigured the wifi on my phone. After that no more issues.
Well i honestly dont know whats wrong with mine. I've done all the "fixes" in this and other threads but it doesnt work. What is weird is that it connects using All Share and only All Share. However it does connect at other places like my friend's, sister's, granparents and gf's houses. I think I'm gonna go to att and demand a new phone and an upgrade
Just wanted to post an update on this. For the most part, deleting the wifi configuration file in data\wifi seems to have cured the problem. The wifi signal did get stuck on one or two occasions, but I'm bound to believe that the issue was caused elsewhere.
I have a stock Skyrocket (4.0.3-IML74K.CLE5) I am using as a media player. I keep it in airplane mode all the time with the Wifi on connected to my router. Yesterday the Play store started telling me there was no connection even though I was connected to my router. I went to the web and found I could connect to pages, but constantly get security warnings. If I click continue I can go on to see the page. Netflix tells me there is a problem connecting to Netflix. Voice search works fine. Google Voice tells me there was a network error. Facebook says it can't find a secure connection. Gmail says no connection. Zedge works fine.
I have tried four different wifi Hotspots both secured and insecure. I have tried telling it to forget the connections and reconnecting. I have restarted many times, removed the battery, and tried all the frequency bands.
The wifi icon in the notification bar shows a strong connection. And the little arrows light up orange and green to show activity.
I am guessing there is something wonky going on with establishing a secure internet connection, bit I have no idea how to fix it. Any advice is appreciated.
Q&A please

Sorry about posting in the wrong spot.
I have been using it like this for three weeks. The problem started two days ago.
Update: it works again. I don't know what I did to fix it, though. I went through every setting, and did turn off screen lock and unknown sources, bit I doubt that did it.
i figured it out, i had the same problem, the date and time were askew. updated them and it worked just fine ^__^
I can connect to the wifi in my office at work. I can browse the internet with chrome and I can even perform a speed test with the speedtest app. However, I cannot download or update apps from the play store. I can do these things via network data. A co-worker has no problem with her GS6 on the same network. Anyone else having this problem?
Nope. And works fine on other WiFi networks?

Most likely being blocked by firewall or the like but that doesn't explain why your colleague can use fine

Haven't tried any other network yet, but I will this evening. Also need to mention another co-worker got a GS7 yesterday and is experiencing the same problem as me. He didn't mention another network and I realize that will be an important piece of information.
Would a firewall allow me to browse and speedtest?
Mine has the exact same issue. It simply won't use wifi for apps other than Chrome. I tried doing some recovery mode steps I found on another site, but to no avail. I have tried it on my network at work and then my home network and still the same. I am going by the Verizon store tomorrow to hopefully get it resolved, unless someone in this arena knows what to do.
Same here. Got my S7 yesterday and 1. Play store will not download apps on wifi but I can browse surprisingly. 2. It seems my wifi signal is weak. I have tried using both my 5 and my 2.4 off my router. Same issue. Taking it tonwork today to see how it does.
Update, but no solution. I am able to do everything on my home wifi network. However, my office network WILL allow me to browse with chrome, do a speedtest, DOWNLOAD apps from Amazon. It will NOT let me download or update apps from the play store and it will not let me stream from Pandora.
Does this make sense to anyone?
My wifi issue is a bit different. It seems to randomly connect/disconnect me at work, but my home network is fine. Never had an issue before this phone.
I had a similar issue and a reboot of my router fixed it..The issue was most notable when downloading from the market
Maybe we don't go to work. Problem solved. lol
Had the same problem as you guys, found this on another site posted in 2014 by djsusant - worked for me
1. SWITCH OFF YOUR MOBILE DATA.
2. SWITCH ON YOUR WI-FI.
3. SWITCH ON FLIGHT MODE.
4. RESTART YOUR PHONE. (KEEP ACTIVATED FLIGHT MODE & WI-FI)
5. AFTER RESTART DON'T SWITCH OFF FLIGHT MODE.
6. OPEN GOOGLE PLAY. WAIT FOR OPEN.
SEE IT WILL OPEN GOOGLE APPS
7. NOW YOU CAN SWITCH OFF FLIGHT MODE.
Hope that helps

Thanks , I tried that when I got to work. It didn't help. I found out that I can download and stream from amazon music but I cant download or stream from the play store or pandora. I wish I knew more about networking, I'd check the settings on our routers.
Having similar problem on home wifi. I have reset home router. I can download and update if I turn off wifi. With wifi on I can browse with chrome. Have to keep turning wifi on and off to do things.
have the same issue except it will work at the store I purchased at but not at home. Tried every remedy but factory reboot so far. There is a great signal to the phone at home but won't download any apps. Facebook etc seem to come in but I didn't purchase this phone for FB. Any help will be appreciated as Samsung reps have been no help.
Pandora isn't working on mine either, not sure if it's a wifi issue only as service is very poor here (much worse than the old G3, tradeoff for battery I spose) so cannot isolate the cause. Will do later. The steps above didnt fix it.
No Pandora and not being able to read the SD card from cpu will probably be deal breakers for me if they aren't fixed within the 30 day trial. Shame, because there's a lot to like with it.
I can say just one thing - at least on the 802.11n networks the signal reception is much lower than e.g. on Sony Xperia Z3 compact .... that is little disappointing .... I was kinda hoping that brand new super ultra class phone with a/b/g/n/ac modem will have also super ultra good signal reception ...
I have the edge and I'm experiencing similar issues. I've also noticed that backups and even ones through Google photos will not work on wifi.
My previous response seems to be only temporary. Ive been doing the DNSet app and it works. So it looks like something on googles end, hopefully they fix it soon
I bought a GS7 edge and have faced the same issues. Unable to download/update any apps via wifi at home. Using a netgear AC router. All my other devices work fine. I've tried restarting the router. Didn't help. Tried both 2.4 and 5G connections as well. What's weirder is the phone works flawlessly on other wifi networks (school and the best buy store I bought it from when I went back to talk to them about it, it even worked off a tethering connection off the rep's phone)
Try switching wifi secirity from AES to TKIP. It helped me with S6 wifi issues

UPDATE (3/15/16)
So we were able to fix the issue as of last night by changing the advanced settings of the network we were connected to on the phone to static IP. This fixed the google play app issues but oculus apps still wouldn't download. We then turned off enhanced 4G LTE and that seemed to remedy it. Phone as of now works fine, hoping this doesn't cause anything else but will be talking to store reps about this soon.
Googled links acknowledging WiFi issues but nothing here? I can't be the only one. Best solution I've found until LG fixes in an update is to run DNSet from the play store. It changes DNS servers for phone to Google's.

Honestly, I've had no issues whatsoever with my WiFi
Long live doodoo
I've had wifi drop pretty frequently to the point i have to turn off data in my home.
I changed my home router to use OpenDNS rather than my ISP's DNS servers, which seemed to fix the issue, but after a while the problems have returned. I've tried booting to recovery and clearing the cache. Right now running DNSet app is a workaround that's working.
I have a Nexus 7 2013 tablet running same 6.0.1 Android and have no issues with it, which leads me to believe the problem is not my router but the LG G5 device.
The saga continues . . . my wife's Samsung Galaxy S6 has worse problems than my LG G5. Hers won't even download or update apps on Play Store. Sometimes Facebook just "spins" trying to update. Meanwhile my Nexus 7 never has had the slightest problem, and all three devices are running Android 6.0.1.
I reset my Belkin AC1200FE Dual-Band Wireless Router to factory settings and reconfigured the 2.4 and 5Ghz access points. I then went on both our phones to "Backup & Reset / Network settings reset" and did that. So far, so good.
My WiFi is slow as well. I went from 171mbs to 30 mbs. I can't figure our what would cause this. What's the difference between my old M9 and the G5
I'm thinking it's Android 6.0.1 affecting certain devices. My wife's Galaxy S6 had zero issues before updating to Marshmallow.

I was having the same painfully slow wifi issue on my home network. It was "Return of the Slowskis". Turned out to be using Duel Band Router. What I did to resolve my issue was make my router 2.4GHz: g, n.... 5GHz I set to AC only. Each has with different names as well. Then I reset the phone's network settingsbto make sure cache was dumped. Restarted the phone.... Set the phone to 2.4GHz and off to the races I go.
