Hello all Seniors,
I am new to this forum and not a techy person.....Recently I update my Samsung S4 (Model # SGH-I337M) phone with 4.4.2 version and now problem started with Wi-Fi network.. At my house, no issue I can connect Wi-Fi without any trouble but in my Office I am not able to connect Wi-Fi network...before updating the phone Wi-Fi was working great at the office. it shows on the phone saved network but no internet at all.
it is kit-kat version -4.4.2 when I hit 5 to 6 times on version button to check which version I am using it came with letter "K".
someone told me to uninstall McAfee app from phone but I checked in my complete app folder but I could not find McAfee app icon at all.
in security folder - Device Manager it shows two Icon
1. KNOX
2. Android Device Manager
any suggestion please? anyone in the forum have any solution or similar experience?

[Q] lost galaxy s3, no internet connection on, no security apps preinstalled

hello, everyone!
my bad if this post is misplaced but couldn't really find a good answer to my specific problem.
basically, i lost my sgs3 today. it had no security apps like android lost, lookout etc. installed and neither wifi nor mobile data were on. have installed from my desktop android lost, but since the phone has no internet connection i don't see how this app can ever be pushed onto the phone.
so basically, my question is if there is anything to be done here? perhaps any code or instruction sent by sms that would trigger the mobile data on!!! i don't suppose so!
anyway, whatever you might think of, i'd appreciate any help!
i'll call the gsm provider at some point to deactivate the sim, unless i can find a way first to locate the phone using their network signal.
many thanks!

Obtaining address... no full connection

Folks,
I just fired up my old samsung galaxy tablet 7. The first samsung galaxy tablet. Attempting to connect to my home wifi after bypassing the activation screen. It just says obtaining address, but never fully connects and there is no internet connection at all on the browser.
- It used to have a verizon data connection but then I deactivated it from my verizon plan
- I factory reset it twice already and the same thing.
- I simply want to use it on wifi.
- I tried other multiple wifi signals with the same result ( wifi signals with NO passwords also )
- Also the super user app is on there from when I tried to erase it. Maybe I messed up the bootload or..the load/OS, I can't remember how to flash the stock one...
I'm pretty technically advanced but this is bothering me a lot.
You might want to make sure you're in the right forum to get help. This is the tab 7.7 forum.
Also before you go posting there you'll need to look up what ROM you're using and find out which model tablet you've got so you post in the right place. People can't help you with the information you've provided so far.

Galaxy S6 Wifi Hotspot cant be found on other devices

Hello everyone,
Longtime Samsung user here and believer in unlocked phones. Recently purchased an unlocked Galaxy S6 to use on Tmobile. I have it setup and working (data, wifi, and calling works flawlessly). However I've encountered an odd issue, I can start the Wifi hotspot, however no other devices can see the SSID being broadcast to connect to the network.
I did several hours of research, even found this thread: http://forum.xda-developers.com/gal...e-hotspot-active-connect-wi-fi-t3098933/page2 ; which pointed me to a couple of solutions I tried:
Enable/disable Wifi power saving
Make sure only approved devices isn't checked
Manually select a Wifi channel (tried auto and manually selecting channels to no avail).
The phone allows me to activate the tethering, and I do have a Tmobile plan that allows tethering, I just can't find the phones SSID on any other device during the wifi network scan (tried multiple other phones/tablets/computers).
This functionality allows me to work remotely on the road, so I would greatly appreciate any suggestions you all may have. Unfortunately due to the BYOD policies in place at my organization (and the root check in place in our apps) rooting is not a problem.
I am open to a third party tethering solution if one exists for this phone on T-mobile. Haven't been part of that scene in some time, so I'm unsure what apps are reputable, so any recommendations there are appreciated.
Wanted to add that the phone was purchased new from Amazon and has android version 5.1.1

Unable to login Synology Mobile Apps via mobile network

Hi All,
Issue: Unable to access Synology mobile apps (DS File, DS Cam, DS Video, etc) via my mobile network however still able to access via Wifi. I was able to access these apps previously via mobile network. I've also narrowed it down to the issue being local to my phone as my wife's phone (Huawei P20+) and my workphone (iPhone 8) has no issue with accessing the apps via mobile network.
Have uninstalled and reinstalled the app.
Have checked app settings set autostart to yes and no restrictions for battery saver. Also no date usage restriction.
Have anyone faced similar issues and found a fix or does anyone have any ideas what could be the problem?
MIUI Version: 12.2.6 Global
Android Version: 11 RKQ1.200826.002
Android Security Update: 01/03/2021
Thanks in advance.

Settings > Connections > Mobile Network > Access Points ... Then select an access point. It seems the update deselects the access point, you just need to reselect it and you will have connection back.

Yeah, cheap tricks.
That's one reason I never update the OS.
Still running on Pie, zero issues.
