Connecting your TV to a Wi-Fi network without a remote can be done in a few different ways, depending on the type of TV that you have.
If you have a smart TV, the best way to connect to the internet without a remote is to use the TV's built-in Wi-Fi capabilities. Most smart TVs have built-in wireless adapters that allow you to connect to your home network without needing any additional hardware. To do this, you'll need to access your TV's settings menu and select the Wi-Fi option. From there, you'll be able to enter your Wi-Fi network's name and password and connect to the internet.
If you don't have a smart TV, you may be able to connect to the internet without a remote using an external Wi-Fi adapter or dongle. These devices are relatively inexpensive and plug directly into your TV's HDMI port. Once connected, you'll be able to access the internet using your home network.
Lastly, if you have an older TV that doesn't have any Wi-Fi capabilities, you can connect it to your home network using an Ethernet cable. This will require you to have a modem or router close by so you can connect the Ethernet cable from the TV to the router. Once connected, you'll be able to access the internet.
