Can I still use WiFi while connected to LAN

My PC is set up to use LAN as 1st priority, and WAN as secondary. I'm using an Ethernet connection, but I see the WiFi still shows "connected" to my wireless router.

I'm considering ChromeCast to stream website video from my PC to TV.

My question is this: Will the WiFi still work and send signal for ChromeCast, even if I have my LAN cable connected, or must I switch the PC's connection priority from LAN to WAN?

Thank you.

PS: Any additional comments about using ChromeCast would be appreciated. So many conflicting reviews...

I would go to the Chromecast website and see what they recomend

ChromeCast.

1st impression, interesting.
Read just a bit info, then i am able to understand better.
This is what i know:

ChromeCast is something like a server connection.

I had accidentally bought a Server HDD.
This Server HDD must be connected to the Router directly by LAN, (where USB cannot be connect to PC)
There is a simple setup and it is easy.
No program is required.
In the Laptop, i need to use Windows Explorer to open the "Network" left panel.
The Server HDD is listed there, open as similar to Windows explorer.

So, this is similar setting, which required a simply setup.
If you PC is streaming video, your LAN cable from PC to router, which is better than wireless.
The Router is now acting as Gateway.
Likewise for Mobile Handset.

Do correct if i am wrong.
I use the way i connect the Server HDD, as even mobile handset turn on wireless, could access the Server HDD directly.

Conclusion: No Wireless is required for PC unless your LAN is having problem, as LAN is faster & stable.
Other devices using wireless, such as handsets.

Your question.

Just use the LAN connection between the Router to your PC. It is not so good to have both LAN & wireless together.
This is that ChromeCast is set as wireless connection to the Router, another internal IP Address.

Answer:
There is no need of using Wireless as all the connection is to the Router as Gateway.
This is how the term is used.
Just a simply straightforward setup.
Even you can streaming video from Mobile Handset using an app, to ChromeCast -> TV

ChromeCast is wireless by itself.

Hope you understand and Thanks for reading.

I am sorry, but I am a bit confused. The only question I have is whether the Wi-Fi will still work on the PC if I have an ethernet cable connected to it, and the connection "priority" is set for LAN. Thanks again

Simple Answer: NO, The connection is only on 1 type, either LAN or Wireless.

But you can still surf internet while streaming video to TV thru Chrome Cast.

This is answer.
Meaning you want to surf internet, while streaming a video to TV thru Chrome Cast.

Correct

When streaming or surfing internet, it works both ways; correctly said,
BOTH DIRECTION <==> As similar to UPLOAD and DOWNLOAD

Now, The Answer is much clear.

Wi-Fi is not required if you an Ethernet connection established to your router. It won't cause any connectivity issue though. As you have a solid connection to your router via Ethernet, it won't matter if you're connected wirelessly as it'll still pick up a connection regardless.

That being said, there might be an IP address conflict, however. It's best to disconnect from the wireless network if you're using Ethernet to avoid any possible network connectivity issues should any arise.

S/He is not stated clearly enough.
Confused.
Nothing to do with IP Address.
As each device had its own IP Address.
Devices meaning include mobile handsets.
As the Router had assign the IP Address to each individual IP Address.

What S/He is thinking is using wireless for streaming directly to Chrome Cast, which is not.
And at the same time using LAN cable from PC to Router for surfing internet.

So the combination of both come in, interesting!!!

Chrome Cast wireless connection is from Router, which act as Gateway; which may confused him/her!

Answer to your question: When streaming a video from the PC to the TV using ChromeCast, I will not be surfing the internet, or doing anything else with the computer. Just watching the video on the TV.

Question:
My ISP uses a cable modem, which plugs directly into a WiFi Router. The router in connected to the PC via an Ethernet cable.

With this setup, will the WiFi Router still be able to transmit the streaming video from the PC wirelessly to the ChromeCast receiver plugged into an HDMI port on the TV?

YES.

The statement should be:

The wifi router is able to transmit the streaming video from the PC via LAN cable to router.
Chromecast will receive the streaming video via wireless from the router.

Router is acting as a gateway.

For connection using LAN cable between the router and the PC is much stable.
But you can use wireless, no LAN cable needed, but may not be stable, it depend.

Do note, there are apps &or program required for these setup.

A simple explanation.
Hope you understand.
