For most folk you give the a rundown of what a Roku or Amazon Fire TV stick or box adds. Older Smart TVs pale in comparison to the Roku and Fire offerings.
In other words forget what you have and shop for a stick or box.
I have a 2007 model Samsung LCD TV LNT325HX/XAA. I’ve tried to connect a 2009 Samsung wireless link to the USB port, but cannot connect to my wireless system. I suspect because it is not a “Smart TV.” Am I out of luck or is there a work around? Thanks in advance for any assistance.
