    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?

    Regards

    Power off the phone. Hold Volume down+home+power on until the recovery screen loads. Use the volume button to select "clear cache partition". Don't clear anything else.

    Reboot and see if that allows you to reconnect. If it doesn't, you'll probably need to ask IT to reset the router and see if that helps re-establish your connection. Let us know how that goes.
