Wifi connected but still not working

Hi, Ive been having problems with my wifi connections lately. Im running stock rom on my vibrant and from time to time I have trouble with the wifi conection. the vibrant will connect just fine with a strong signal but will not load webpages, or open market. This problem happens sometimes. The connection is a secure wap. I am wondering what I can do to fix this issue, its really frustrating.
Thanks in advance
btw all other devices in the house have no problem connecting and using this connection. Sometimes I will have my laptop in front of me using this very conneciton.

Happens to me all the time. Have to disconnect it and reconnect. If it still doesn't work, you have to reset your phone.

My friend is having same problem with wife on his Vibrant....is the a hardware or software problem? Because I had Captivate and it never had this problem since I had the phone.
WIFI is good and connect is Excellent.... but just can't use it to surf web or log on fring.....HOWEVER, it was able to logon the Market today using wifi.. Does anyone know why and how to fix this problem?
Thanks!!

What exactly do you mean by reset? you mean a factory restore? Im finally likng the battery life on this phone I dont want to lose that, will that be affected? Is there any other fix?

Wifi Not Working Correctly?

I tried searching and I have not found a solution yet. I'm running SHOstock-I with ktoonz kernel on android 4.4.2.
For some reason, my Wifi randomly disconnects from any currently connected wifi network. The first thing I try to do is to connect back to the wifi network (any available network), but it simply tries and says "Connection Failed". Next, I try to disable the wifi connectivity alltogether, but after I tap the toggle button it becomes "greyed-out" and I can't toggle it.. it just hangs. If I go back a step and then select wifi again, then I can try to disable it but the same thing just happens again.
If I reboot, then wifi works again.
Oddly enough, if I enable/disable teathering, then wifi starts to work again.
It seems I can't run Wifi for more than an hour without this issue happening. It seems to have just started doing this out of the blue. I suspect a full wipe would solve the issue but I'd rather not do that unless I have to. It usually takes me a while to get things back to normal after a wipe.
Any ideas?

Some solved the problem by unInstalling the Smart Wifi utility (for ATT and maybe other carriers too).

Thanks, but I don't have that app installed. I am positive this is not a router issue as well.
Everytime I wipe cache/delvik then the issue doesn't occur for a few days, which I think is odd. I also tried different kernels and the problem persisted.
Does anyone know if it's possible to confirm if this is a hardware issue? I doubt it...

It is a good idea to turn off any 'connection optimizer' or 'wifi optimizer' application or setting, in short anything that decides what connection is selected based on available connections should be turned off. The most probable reason for the problem is badly programmed software.

Serious WiFI Issues

Hoping someone can help me
My S7 Edge WiFI connection is playing up. My phone is fine on data network but only when connected on WiFi (Have tried other networks too) it has some serious problems like,
- Whatsapp notifications not received unless I switch to data connection or open the app
- Trouble loading internet applications, they just hang randomly but if I switch to data then they load
I first noticed this when I switched over to SuperManROM, however I have since reflashed the previous ROM I was using and still have the same issues. I've tried custom kernels and stock kernels and no difference.
Is it simply a faulty WiFI chip in the S7 Edge or coudl it be something software related? An important point to mention is that for the SuperManROM I had to update the bootloader and Modem, but I did downgrade them again to see if there was any change
Please help

Having the same issues. Tried multiple Wifi networks, same issue. Shows I'm connected to it, but no throughput. Tested the same networks on my laptop with no issues.
I'm using SuperSU.

This happens to me too, but only when I enable power saving mode, could that be your issue?

Well I thought it fixed it, but it doesn't look like it did. Rebooting the phone to see if that helps
Update: even after a reboot no luck.
On cell data no issues. As soon as I connect to Wifi, I lose it.
Update 2: Had a system update available. Tried to install it, and after the phone rebooted it told me the update failed, but the Wifi works okay for the moment. Honestly no clue.

You guys got any VPN profiles installed or anything?

Great to hear that the problem is fixed for now, hopefully the problem won't return!

Wifi not connecting automatically to saved networks

I have been experiencing an issue where wifi is not auto connecting to saved networks after being on 4g data. Refreshing the Wifi screen does not bring any results until I switch the wifi off and on several times, and then the relevant networks are shown and DO auto connect. I am rooted with an unlocked bootloader, xposed. This is not new to gaining root, but happened about 10 days after. Has anyone experienced this issue and what did you do to fix it? Any help would be appreciated.

Yeah its happening to me. It doesn't connect and when I go to wifi settings, it looks like it's refreshing but no networks show up. I have to turn it off then back on and it auto connects. I'm fully stock, unrooted. I think a software update can fix that.

Got same issue with A2017G.
How can a phone be released with such defects??? Anybody at ZTE even used the phone 2 or 3 day in a row and didn't noticed that?

I'm having the same problem, I can't get onto the wifi at my work, or at home.

Weirdest issue Data & Wifi connection but no internet???

Hi, I have got a very strange issue, I have data and wifi connected but cannot connect to the internet with either, if it was just one or the other but with both data and wifi, I have tried many 'fixes' but nothing works, I restart the phone and both work fine for a while but after I wake the phone from standby neither work again... maybe this is a clue any ideas? thanks

What does not work? Is there only a particular app that doesn't work over either one of them?
Did you ever use a VPN for this phone?
Also, do a factory reset and see if getting back to the original settings it will work.
