On my laptop have it forget my network connection (varies widely on laptops!) Then I connect again. Sometimes I have to go to the router and find a menu to forget the laptop's IP reservation.
I have a Samsung Smart TV and many other wireless devices in my house. However, whenever the TV is on it restricts access to the internet from my personal laptop. All other wireless devices work fine. Whenever I try to use the laptop while the TV is on, it will say "IP address conflict" and won't access the network. Any help?
