Bought a new Samsung smart tv today. Once the tv was all set up, it had to connect to the wifi. It eventually worked but some of the devices in my house struggled to connect. One laptop and an iphone connected, but a different desktop and 2 other phones wouldn't connect. After resetting the router, the desktop and laptop connected fine and worked. But now none of the phones work. They show the wifi as joinable, but don't fully connect. Everything is wired correctly and the internet speed is the same as it was before the TV. Any suggestions? New router? thanks guys!
