S5830 Wifi connected but internet doesn't work

Hi guys,
I've been trying to solve this on my own for a long time, but I've found no clue on how to do it.
I have an ADSL2 router with wifi at home and many devices connected to it via wifi (smartphones, notebooks, pcs) and every one of them works fine. Only problem is my Samsung S5830 which connects to the wifi, THE INTERNET WORKS FOR A 4-5 SECONDS and then it just stops loading pages and everything else, it is connected to the wifi but the internet doesn't work. Every other device works on that router but this Ace. Strange thing is, that on other Wifi (hotspot made by my HTC One) the Ace works just fine, so it is not a problem with Wifi driver/rom or something like that.
Solutions I've tried :
1. *#*#526#*#* code to restart wifi driver
2. Using Static IP
3. Changing DNS
4. Restarting router/phone many times
The router is TP-Link TD-W8961NB.
Strange thing is that I cannot even access the router's configuration page on 192.168.1.1 after that 5 seconds, so the problem isn't just in accessing the internet.
Also, I've checked all firewall/security/blocking functions of the router and none of them should be responsible for this, noting that all other devices work.
Thanks for any other ideas, I'm seriously fed up with this.

Wifi problems on certain networds (CM11 Android 4.4)

I got a wifi problem on my defy with CM11 Android 4.4.
At home I can connect to my routers wifi perfect.
But in school I can't connect to any network. The school has two available networks, one with a password and one without password that authorizes you through the browser.
I'm unable to connect to either of these. They have full wifi signal, but when I click connect they immediately drop to 1 "bar" and disconnect. After the disconnect I got full wifi signal again, but when I connect to drops to zero immediately.
Any idea on how to fix this? Maybe some of the network drivers having problems with networks with a lot of users?

Galaxy Tab A 8-inch (SM-T350) Wifi/internet issues

Hi everyone!
Recently, I bought my mother a Galaxy Tab A 8-inch device (Model Number SM-T350) and it theres an issue where the device seems to be connected to her Wifi network, but after a while, she is not able to browse the internet or use Viber. The Wifi Network shows connected. But after a specific time, when she needs to use Viber, she cannot connect to the internet even though the network is connected to her Wifi network.
Its not only Viber, but she cannot browse the internet using Firefox or the native browser.
The only way to resolve this is by turning ON/OFF the Wifi.
We tried a number of things like Setting the Sleep options to Never disconnect from Wifi, resetting the router, and so forth...
I tried updating the device but it seems like that this unit only goes up to Android 6.0..1. There is no security software that I know of installed on the device either. I checked the router settings as well and all devices going through that router are not Blacklisted. So all devices can pass or connect to the network. No MAC address filtering turned ON, it is OFF. But these settings are irrelevant to the issue in question, as the device Wifi shows status as Connected...
This is quite a "PITTY" situation as her Viber contacts cannot even call her either because of this issue.
To recap or to sum it up on the issue, is that after a while the internet does not seem to work on the device even though its connected to her Wifi network.
My mother does not have any other devices at her home.
I wonder if this is an Android bug or there is an issue with our router?
The router in question is a Cisco WRVS4400N if this helps.
Thanks

Bump. I have the same issue with my Tab A 6.

How old is there router

I have a similar problem with the Samsung Galaxy tablet a. My version is SM-T350. When I 1st got it a few years ago, everything worked great and I was able to connect to the Wi-Fi no problem. However, I believe that was after an update, the tab A will no longer connect to the Internet in less it is sitting right next to the router. Even this can be sketchy. It has to be within 2" to connect. I don't think it has anything to do with the router, but something with the internal Wi-Fi. I was thinking before when I wouldn't be able to connect it I had to select WEP instead of WPA

[A5 2016] Can't see 5GHZ WiFi after setup is complete

Whenever i setup my A5 2016 after factory resetting or initializing with Smart Switch i can see my 5GHZ WiFi network and connect to it, but after the setup completes it disconnects and i don't see the network anymore. Wtf

Update: For some reason right after i posted this thread i can now see and connect to the 5GHZ network
Update 2: So my phone's battery died and when i turned it back on i can't see the 5GHZ network anymore. I'm running the latest Samsung update 100% stock

[Problem] Wifi Hotspot without internet connection

Since the last official update I'm always having problems when I turn on my wifi hotspot to use my other phone with the Zenfone Zoom Data.
When I turn it on it doesn't work, my connected devices show "no connection" when connected to the wifi hotspot, I manage to get it working always swearing while I reset the wifi and data settings, I turn on and off the data and the wifi hotspot. Sometimes I have to go to the VPN and re-tap on the correct VPN in use (that is already selected) and then the connection will stat working on my connected devices. Often I have to repeat those steps many times.
The other weird thing is that when I'm using the Zoom S as wifi hotspot, the connection on the phone itself stop working. It works only on the connected devices.
Never had those problems with previous android phones I had (several Nexus, a Note 3 and an Ulefone Power). I use the wifi hotspot really often since I still use my Note 3 and this is really frustrating.
EDIT Maybe I posted this in the wrong section. My mistake sorry. If some mod can move this I'll be glad.

try adding ",dun" to the access point types under the APN settings. I had a similar issue that fixed it.

Last week I used my Asus 3 Zoom to give my laptop internet by Wifi hotspot. Worked flawlessly.
