It took me several hours to operate the wireless module in Infrastructure mode. It's madness what poor quality the appropriate firmware. Constantly the wireless setting is off, then it's back. Then you have to try by various methods in WPA2 routers until a go. But the biggest joke is probably the SSID: you have a WLAN with a separate SSID by spaces ("My WiFi"), then this network is not recognized by the router found and displayed. Only the removal ("MeinWLAN") shows the network at all.
Bugs usual I looked for a firmware update. But Samsung delivers nothing there. Although the errors have long been known so, how one can see the data of the reviews. If I were to deliver a software developer such lousy software, I had the job for the longest time.
