The tv is both wifi wireless and can be hooked up with a cable. Even though it works through wifi, do not be confused by thinking that you can surf the Internet. It is strictly used for the apps which you can download right on the tv. I have had for almost a month and have had no regrets! This tv is awesome for the price point!
Hello Lynne, Please download and read the PDF File of the User Manual before using this TV for the initial set up. The TV has the Wired and Wireless WiFi features. You can choose either convenient to your settings. The Cable connection is better if your Wireless Signal is weak.
This tv is completely wireless (for Internet apps) and does not need an Ethernet cable from the modem. Just needs to be in range of wireless router. Took less than 30 seconds to establish wifi settings and connection successfully. I hope this helps!
