I'm sorry to hear that you're having trouble connecting your TV to connect.
In most cases, inserting the LinkStick should bring up a prompt asking if you want to change your network from wired to wireless (as wired is the default setting). If this isn't happening, try to go to your Network menu in the TV and search for an access point. If you're not able to perform this task and see a list of nearby wireless access points (assuming you have a wireless network in place already), the LinkStick may be faulty.
My TV is not recognizing my wireless adapter (WIS09ABGN). I thought it might be my firmware needed updating so I did that through a USB stick, which was successfull. Is there something else I need to do? I don't see anything about network on the menu set up screen. There are no instructions or anything that come with the adapter and the manual for the TV didn't help either.
