Wifi problem just reared its ugly head after 48 hours with official Froyo

I may have bragged too soon on good ol' official Froyo. I had a smooth install and the only problem I've noticed is the messed up Quick Office deal like most others. Today I just had another problem start.
I've been using my secured home wifi network fine, but for some reason the Captivate will no longer connect to it. I've tried doing a battery pull, turning the phone off and back on, and even completely removing the home network from the list and then putting it back in. I'm sure the password is correct. It just sits there, saying "Obtaining IP address". It retries several attempts, and eventually gives up and lists my home network in the list as "Disabled"
This is significant suckage!

I had similar problem try unplugging router and plugging back in

Bless your heart! That did it! I just read on the AT&T forums that someone else had the exact same problem and he did a factory reset of his phone which fixed it. I was hoping I wouldn't have to go there

I found an easy solution to the problem. Open Allshare, then you should be good to go.

After opening Allshare, hit connect.

Yes sometimes power cycling the router is all that is needed. I notice this with laptop sometimes too.

Yeah that was me...
I tried everything else before the factory reset, but the reset fixed it, now I've got wi-fi with no problems

If you do a factory reset, I realize you have to reinstall all your apps, but what about the ones I paid for? Will I have to purchase those again? I'm thinking of doing one just because I think it will smooth things out and get rid of a couple of weird quirks like the Quick Office icon problem.

anything you purchase with your google account is tied to your google account. you dont have to re-buy those...for any phone that you log into your google account.

Has anyone tried my fix? Sure beats having tofactory reset...I'm just sayin.

It works, but you have to do it every time, so it's more of a workaround than a fix.

I had an issue with connecting to one of my work wifi routers (would just sit there saying 'obtaining IP address' but never would connect) and could not fix it until I tried using "FXR WiFi Fix and rescue" app from the market. Free app, will erase ALL of your saved WiFi data so make sure you have your passwords for encrypted networks, but this fixed it with one click and a reboot. Seems to connect faster to the networks now as well. I had a similar problem after the previous update that went out OTA and had to reset the phone for that one.

I thought about trying this app, as my wifi issue returned today. I thought I had gotten rid of it by doing the factory reset, but alas it's back. I'm really contemplating a custom ROM more and more every day. I just don't know which one to go with that will provide everything I need. This app sure asks for a lot of permissions, so I'm sort of leary about istalling it.

Welp, I bit the bullet and tried the FXR app. No dice for me. I'm waiting for the wife to get done surfing so I can try a router power cycle. If that doesn't work, I'm looking at my second factory reset in less than a week. Froyo, you suck! I never had wifi issues until I upgraded to 2.2. What I can't understand is, why some of my issues are better, yet some are worse. Is it that difficult for these idiots to figure it out?

Just going to throw something out there, that I noticed yesterday. I'm on a custom ROM, but I noticed some pretty flaky results to my wifi, but only when I was using the modified TouchWiz launcher. The wifi had trouble connecting, and wouldn't sleep. The notification dropdown widget wouldn't control it. Then I switched to Go Launcher EX, and the behavior stopped.
Check another launcher, and see if that makes a difference. Sure, it's a longshot, but I'll be interested to see if the stock TW has the same issue as the modded version.

I was having the same wifi problem after updating firmware to official 2.2 kb1. I used fxr and now wifi connection works great.

[Q] No Images when on WiFi?

I am running stock Kit Kat except that i have my phone unlocked and rooted.
What is happening is that when i am connected to wifi i am unable to load images on the play store, or any browser. Games work, video works music works, but images wont load.
I have no problem on my nexus 7 connected to wifi or any other device i have ever had. If i disconnect from wifi and use cellular it all loads just fine. Can anyone lend a hand on this for me?
Thanks
update: turns out that you tube thinks i have no network when on wifi, but other apps seem to work and think they have a network just fine.
Update: must be something to do with the router, when i connect it to a wifi hotspot it works fine. ???? thanks anyway.

Doesn't seem to be an issue with the radio on the phone, especially if you can connect to other hotspots without issues. Factory reset the router, that should fix the problem.

Try checking to see if you have any adblocking on your phone and disable it and try loading pictures up.

Thanks I'll give them both a try.

OK so no add blocking and that couldn't be the case as you tube and hangouts and google+ all behave as if I have no network. I will try the router reset and cross my fingers. I just updated the firmware on my netgear r6300.

Ok after testing resetting the router gave back a small bit more but non of the Google services act right such as no images in YouTube but I am at least not getting a no network error. This same issue now exists with my nexus 7 2013 after installing kit Kat. Now I am pretty sure its not my hardware, instead its the modem that's installed with kit Kat on both devices.

[Q] Wifi half not working

I have a moto g 8gb. It is rooted and i am using infusion custom rom (and have been for the past month). Yesterday, my wifi started being faulty. It works perfectly (though a bit slowly) for internet browsing on google chrome, and i can send hangouts fine. However, when i try to download or update an app from google play store, it doesnot download. It tells me it is downloading but after about 5min it says could not download. I also cannot connect to the internet in any games eg. candy crush and my instagram feed does not refresh. This occurs at home and work so i know it is not the wifi provider. Also, when i switch to 3g the apps begin downloading straight away.
I have tried rebooting my phone many times. I have tried lots of wifi fixer apps none of them help. My phone thinks it is connected but only chrome and hangouts works. I tried a factory reset then a TWRP restore to no avail. PLEASE HELP

Anyone else have wifi issues with GS7?

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.

No play store only on WIFI

Guys, everything was fine. I just got this phone today via cricket and as I always do I first connect to our WiFi network than to the play store. Everything was going fine and update was going good than all of a sudden I get error. After digging google I come to realize play store wont connect when on WiFi but work without any problem when on LTE mobile network. Can someone please tell me what is going on here. I never had any issue like this before. Everyone else's play store is working fine on our network so it has to be just with my case. I tried to clear data/cache, reinstall play store, delete google account than relog...I am lost now. I don't know what to do and what is happening. Any help would be much appreciated guys!
