Phone connected to WiFi but not IP being pushed and Internet not working - Verizon Samsung Galaxy S III

Hello XDA Members,
I am having a mysterious issue that has been very annoying. I have an EVO Wingle Wifi Device for Internet from PTCL in Pakistan.
It was working fine a couple days ago, my phone used to connect find to the wifi of the device and I was able to use internet on the phone, but all of a sudden one day, something went wrong.
Now the issue is that:
1. The phone can connect to the wifi, and it says "connected" but the device is not pushing the phone an IP anymore, it says "::1" in that place, and also the internet is not working on the phone.
2. On the devices stats page, I can see all other devices connected to the device, but not the phone. The wifi limit is 5, and I only usually have my laptop connected with it.
3. I also have tried to use a static IP on the phone like 192.168.1.128 and manually set it on the phone, and the phone still connects to the wifi, and it shows the IP, but still the internet doesn't work and the device doesn't register the phone in it's stats.
4. All other devices can connected and work fine with the wifi, with the internet working on all of them.
5. The phone works with any other wifi connection fine, just not with this device.
I have tried to:
1. Factory Reset my device, it didn't solve the issue.
2. Forget WiFi many times on phone, used different passwords, clear settings, etc.
3. Reset the phone, whitelisting phones MAC address on the device.
4. Used wifi fix apps from google play without any results.
But nothing seems to be fixing the issue.
Now I am at loss, I don't know what to do anymore, can anyone help?
Device: 9.1 Evo Wingle WiFi Device, PTCL.
Phone: Samsung S3 Verizon - Running KitKat 4.4 with CustomROM (SUPERLIGHTROM V5) with Safestrap, and rooted phone.

[Q] wifi not working on GB 2.3.4

I am not able to browse on wifi network. Wifi toggles to on position, can scan the network but not connecting
My phone is running on stock Indian ROM 1.52.720.3 with S-off and rest everything stock, "NOT ROOTED"
Till 2 days back it was working fine and i could use the wifi network
Now most of the time it does not connect to the wifi network, it keeps scanning, detects the network, attempts to connect and finally says disconnected.
Sometimes it connects, i can see the assigned IP but not able to browse the internet or use the android market.
However internet pass through option is working when plugged in USB
I am able to connect my laptop to the wifi network and use the internet, so my network is fine.
I spoke to the customer care, they told me to do a factory reset from Bootloader option...I did the factory reset but still wifi not working
Any help please

I haven't had that issue with the stock ROM, and but it has come up with some modified ROMs. The solution has been to scan for the network, and attempt to connect and then disconnect & forget the network. Rescan and connect worked perfectly after that.
Worth a shot.

A510 NO internet connection

A510 connected to router, can easily access files stored on lan, but I can't open any webpage ("Webpage not available", same with gmail or facebook). If I conect my HTC Desire over wi-fi to the same network, internet surfing works without any problem. I also tried connect to other network, turn off - on tablet but nothing new.
I am sure that yesterday it worked ok, but after that was only using lan connection.
Last night I have rooted tablet (using simple method), installed SuperUser, then TitaniumBackup, Asphalt, GTA3 and Kineticalc (from mobilism) and at the end tried to use cifmanager (without any success). I do not know if anything there make something wrong.
What to do?

Now I made reset under settings and at first boot it asks to sign in to google but I can not do that since network connection is still not working
Ive tried a few apps that didnt connect properly after bieng on another network for some time, particularly apps that needed authentication like Dropsync, and I sorted it by having my tablet connect to the internet through my mobile data connection. I dont know if your HTC Desire has that, but on my Sensation I just started mobile data and wifi hotspot, connected my Tab to it and was able to get online with any app on the tab. When switching back the Tab to my home wifi, everything worked as it should.
Might be a dns reset issue, that the Tab is forced to do on connecting to another network, it has to, but I cant say for sure that this trick will help you..

Wifi stops working after being left for a while (still connected)

Having an issue with the Tab 2 where you go to pick it up and start browsing after it has been sitting around a while (not sure if the time matters, but it seems like after sitting for most of the day) and the wifi is still connected, but nothing works than needs data. It acts like it would if you had not internet connection. Toggling the wifi off and on will fix the issue and notificaitons and emails start pouring in.
Anyone else have this problem? I found a similar issue on the 7.7 forums but nobody reported a solution and I am not even sure if it would have worked on the Tab 2 anyways. I am thinking about making a script that toggles the wifi automatically if it detects it can't connect to the internet. But that is a little ridiculous needing to do that. It shouldn't be losing connection in the first place.
Hi Pirate
it's a bit depending on the ROM you have installed - but since Android 4 you have a quite reliable setting. The default behavior of Android devices is to deactivate the wifi connection when it goes to sleep.
Some ROMs don't recognize the disconnection and the switch/button still shows "Wifi on" although disconnected.
First step: go to settings / wifi settings, hit the menu button (top right three dots) and check the advanced settings.
Somewhat like "Keep WLAN active in standby" - set this to always.
That should solve it already under android 4.x
If this doesn't help, look into Play Store - search for "wifi keep alive". But for the SGT 2 you shouldn't need it
Greetz - Chris
It was already set to "Always" so I don't think that will help. I will look at that app to see what it does.

wifi turns off when not in use to save battery. I think it might be a default even if you have it set to always on.

The problem is that it never comes back on. Well it shows the wifi icon and the signal and everything but it just doesn't have any data connection. Any apps that use data act like wifi is off. The only way to get it to start working again is to toggle wifi or reboot. I also forgot to mention it is the stock ROM, only rooted. It got the OTA a few days ago too and it has happened since then.
You're not alone

It's the same effing stuff people suggest to every wifi glitch out there.
To people who think it's due to the wifi sleep policy: although I've set it to always, why would wifi not resume, after screen is turned on? It's not the wifi that gets disconnected, it's the internet (or the download speed) that stops working.
To people who suggest it's a power saving feature under low battery conditions: Sorry, I've tested it while charging and with full battery.
To people with the above two arguments: Connection to some routers works perfect with the phone. Like when I turn on the hotspot on another phone, the wifi works great. Also, wifi on the other phone from the same source (laptop used as internet access point) works well.
To people who suggest resetting the router or wifi on phone: The internet does start working again, but only for a few minutes. Even if the screen is turned on, the internet may stop working mid-download.
The actual situation is that the phone disconnects from the internet, but keeps showing a connection to wifi. Like I used connectify hotspot to create an access point, and after a few minutes, the phone moved from "connected clients" list to the "previously connected clients", even as the phone showed connected to wifi with even the download arrows blinking, but no internet (or download speed). This only happens with certain sources (of wifi). And other phones may work well with the same source.
I have tried (several times and in different orders and permutations) the following to no effect:
1. Resetting the router.
2. Resetting the wifi on laptop.
3. Resetting the wifi on phone.
4. Restarting the phone and laptop.
5. Static IPs, gateways and DNSs. (Even though the problem was not with connecting to wifi and even internet works momentarily after resetting wifi).
6. Turning off items controlling wireless network in wireless connection properties.
7. Turning off firewall.
Waiting for a savior.
I know this isn't super helpful but I had the same bug you describe on the previous version of carbon. When I updated to the latest it seems to have stopped.

Same issue. also using connectify and also tried all things you have described. If you find any solution please let me know.
I had the same problem on my Huawei Honor. You need to set static IP in wifi settings (when connecting to AP, press "show advanced settings").
Mine settings were:
IP adress: 192.168.1.75 (make sure other devices are not connected with this IP)
Gateway: 192.168.1.254 (it could be different. Use the same as you're using to connect to your router)
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 4.4.4.4
No option for static IP in connectify

There is no option in connectify for static IP and in USB wifi dongle also there is no option to set static IP.

1. I have had the exact same issue for (atleast) the past 2 years. Have survived by repeatedly turning wifi on and off.
2. I too use connectify. This issue doesnt seem to happen on every wifi connection (just like your case). Even more specifically, it seems to happen ONLY when I connect my phone to the hotspot created via my laptop (connectify).
3. Even when the internet is actually working, some apps do not seem to recognise that(take some time to realize it is working), while others are able to connect instantly. Specifially, whatsapp is unable to send/receive messages for about 1-2 mins, after which I receive a whole bunch of messages at once.
This does not seem to be an issue due to connectify as well. I have tried creating a hotspot from my laptop without using connectify as well, but unfortunately, nothing changed. Further, this does not happen when my phone connects to a hotspot created via connectify by some other pc. The wifi and internet work perfectly fine when connected to a hotspot created via my friends computer.
Further, this problem happens only when a mobile connects to the hotspot. Doesn't occur when another laptop/PC connects (not sure about tablets).
I have looked into every nook and cranny on the internet, explored every forum for any working solution, but have been unsuccessful. In fact, this is the first place where I saw the exact same problem as mine, and was wondering if you have found any solution to it .

I'm having the exact same prob on my ZTE Grand x V 970
It started when i had kitkat and i couldnt even "fix it" restarting the wifi, i had to reset the phone in order to have my wifi work for like 2-5 mins and then stops recieving data, tried to reconnect and stays on turning on wifi.. Now i changed to the stock Rom and the problem is still there but at least now i can "fix it" restarting the wifi connection until certain point.
Issue sharing internet with Connectify from PC
Go to:
Control Panel\Network and Internet\Network and Sharing Center
On the left column, click on CHANGE ADAPTER SETTINGS.
You should be in: Control Panel\Network and Internet\Network Connections by now.
Then click on: Microsoft Virtual Miniport Adapter and click on Properties, then click on the 'Configure' button in the 'Networking' tab. From this window, go to the 'Power Management' tab and uncheck 'Allow the computer to turn off this device to save power'.
This works for me. Try this out
If this doesn't work further, you can try out mHotspot for the same purpose.
I've had the same issue, with the wifi saying it's connected even though it isn't.
This thread is 4 years old and this issue still hasn't been fixed. What a shame.
Same issue here on OnePlus 3 even after factory reset.
I have this same problem after the security patch Mid March to Jan 1, 2019. The WIFI doesn't show in the top status bar, but toggling wifi off/on fixes it till the next overnight. I did make one change to my wireless about that same time and that was moving the min connect speed from 6Mbps to 12Mbps to help with bandwidth issues being cause by devices using low speeds and having several SSID broadcast. My S7 and Tab A both work fine - so I think it was something in the security patch.

[Q] One device has connection problem, but not others

Hello,
Airdroid works fine on several devices here (my phone, my son's phone, my mother's tablet), but is very picky on my mother's phone.
All devices are connected on the same wifi network.
She has a samsung GT-S5839i. Here's what happens:
First, after installation, connection was ok.
Next day, no connection, the browser could not reach the phone. My phone could connect (over same wifi network, same browser on my PC). I restarted her phone, launched Airdroid : works fine.
Today, one day later: everything the same: not working at first, I had to reboot her phone.
So she has to reboot her phone to use Airdroid, that's not very convenient
What could cause this? How can I investigate this issue?
Thanks a lot ^_^

[Q] Phone will not connect to Wi-Fi at work

I’ve received my One on Monday. It’s working very well except it won’t connect to the Wi-Fi network at my work place.
1) The phone connects without problems to my Wi-Fi at home
2) I have the exact same Wi-Fi settings for the work network than the ones on my other android phone which was connecting just fine to this network.
I’ve rooted the phone but otherwise I’ve not changed either the ROM or the kernel.​Any idea what might cause this or what I could do to fix it?
