I don't have any detail to work with here. We do know that hiding the SSID and more can break WiFi on some devices.
Your post has so little detail that I can't tell if it's something we know about. To help others we have the top posts over in the CNET Networking Forum and a post specific to Samsung devices.
Tell more and if you can't change the router settings, I need to know that so we can stop before we start.
Hello, I own a samsung galaxy tab 7.0 plus and everything was great till it went dead one day and didnt start again. the reason it didn't turn on again was that i lost my charger and the laptop charger couldn't help the battery to start. So i had to take it to a Samsung maitenance point where they did a system upgrade. Then my problem with the wi-fi connection started. My problem now is that i cannot connect to my home wi-fi but i can connect to my office wi-fi. Mind you that i connect many devices at my houses's wi-fi connection: laptops, other mobile phones.... and they all work perfectly, except my Galaxy tab.
can anyone help me connect back to my house wi-fi connection please?
Thank you so much in advance.
