WiFi direct connection between Laptop and Panasonic Smart TV

[zuzicuts]

Hello, this morning I installed windows 10 on my laptop, DELL 7720SE, and I wanted to see if i can extend my display to my Panasonic Smart TV TXAS650E via WiFi, it worked like a charm, easy and simple, i selected the option mirroring on TV then on my laptop, from the display settings I selected Connect to a wireless display. I managed to connect to the TV and watch a few movies, this afternoon when i wanted to connect again, the laptop can't find the TV anymore. I managed to mirror my phone on the TV, also I managed to play a video from laptop to the TV via the mirroring option in the windows media player, but I can't extend or duplicate the displays again. I have been trying to find a solution but all the suggestions were to get a HDMI WiFi adapter. I am looking for a solution that doesn't involve any other additional devices since I was able to connect this morning, but I can't connect now.
I would appreciate any suggestions.

Thanks for you time.

Since you were originally able to get it to work then I would not expect that other hardware is necessary.

Instead, I would look at how the various IP addresses are being assigned. i.e., static or dynamic. Plus double check any necessary port forwarding.

DHCP devices can get a new address assigned each time they join the network.

Probably need to reserve static IP addresses via device MACs to get it all to work consistently. Devices that lose power/get turned off may default to IPs that conflict with other devices.

Work to set it up again and track the IP addresses being assigned and to which device if static IPs are needed.

I would try setting a static IP configuration for the smart TV, and as mentioned ensuring the proper ports are allowed through the Windows host firewall.

Maybe try reinstalling video car driver also.
