connecting wifi to a TV (Sony) SMART

Not sure about T-Mobile and new devices (outside of my phones/Macbook).  I have plugged the T-Mobile gateway into my existing WiFi router, so that I don’t have to make any network changes on my end, and everything just works as is (i.e. unplugged cable modem + ethernet jack, plugged in T-Mobile gateway + ethernet jack into WiFi router).

I get better range with my own gear, and a lot more control.

@Greenhats Find the Network section in the TV’s settings menu.  Look for something like “Set up connection”.  Let the TV scan the available wireless networks.  Select your T-Mobile network and type your network password with the onscreen keyboard.

Hi @Greenhats, I’m assuming you are trying to make a wireless connection. I have a TCL Roku TV. Every smart TV is a bit different, but in my case the setup is Settings > Network > Set Up Connection > Wireless.  It will then scan for available networks.  Once you choose the “T-Mobile” network you would enter your network passkey. It should then connect to your network.  Are you getting an error message after entering your passkey?  There wouldn’t be anything that needs connecting to the back of your TV, unless you are making a wired connection (Ethernet).

@Greenhats Are you able to connect your other devices to the T-Mobile network? Assuming you are, are you getting a good signal near the back of the TV?  (Use your phone and the Speedtest app.)  If that is the problem, try moving the gateway to somewhere closer to the TV, but still able to connect to the tower.

Next try unplugging the TV for at least 30 seconds.  Then try the TV setup again.

The next thing is to read this article -- https://www.lifewire.com/how-to-fix-vizio-tv-wont-connect-to-wifi-4685906 -- though some of it isn’t relevant to the T-Mobile gateway because it has very few things we can change.  I can tell you how to set up a second T-Mobile network (on the same gateway) with WPA/WPA2 security if you can’t get the TV to connect to the default network (which has WPA2/WPA3 security.)

   I did move my gateway closer to tv. It goes to excellent to very good.but still wil not connect . I did get the app speediest which is a scam because they wanted my credit card number but there would be no charge for using. When my bank detects something unusual they call me. They were going to charge me $39.00 which I declined. Do you have any other suggestions.

Called TMobile ant got it working. Hurray can I put as many devices on gateway. I was going to put my I-pad on it. Then I going to get rid of my high outrageous cable company. I hope I don't have a contract with them because I don' know if I do. Thank you for helping me out.
