When you turn on Smart TV, every time it gives an error no connection to the network
Answer
Good evening. It’s a TV, the problem could be anything. They have their own quirks. But I don’t think the wifi problem is because of the wireless keyboard.
I can’t tell you for sure if LG’s Smart TV has a “reset network settings” feature. It would be good to do that. Maybe after that the TV would remember the password and would not ask for it every time giving the error “no network connection”. After all, you probably don’t want to do a full reset of the TV.
Check if there is a firmware update for your TV. If there is, update it. Perhaps the problem will be solved.
Another option is to change the Wi-Fi network name in the settings of your TP-Link TL-WR740N router. Information on how to do this can be found in the TP-Link TL-WR740N setup manual. After changing the network name, the TV will see the Wi-Fi network as a new one. And there is a chance that it will remember the password from it.
Isn’t there any item like “Connect automatically” in the connection process?
