Which model Samsung?
Do you have the User Guide/Manual?
If the TV has built in wireless then no you should not need a "second" wireless adapter.
If the TV has a USB port and is designed to and allow you to install and configure a wireless USB adapter then maybe so.
The TV would receive a DHCP IP address and appear on the network just as any other wireless device. You would need to use the TV's menus, if any, to configure the TV accordingly.
The User Guide/Manual should provide the necessary details if a wireless network/internet connection is possible.
