I have a Smart TV with internet connection.
If I want to surf the laptop and the TV stays off, I have no problems.
However, I turn on the TV first and then the laptop, I get no internet connection. Also not with interruptions. Even if I turn off the TV again. Only when I start the router completely again, I get a connection to the laptop.
Could it be a wrong attitude?
What you describe there with no connection make absolutely no sense on the tv related… The changes nothing in the existence of your signal he weakens it at most.
And if you turn on the notebook and then the TV? Can both of us internet?
Then it works with the laptop first and once the TV is on, it flies out again.
How are the devices connected?
WLAN or LAN?
Go into your router and assign the devices a static IP.
