If I have my Ethernet connected to a device will the wireless internet still work for other devices?

A wireless router can provide simultaneous Ethernet and WiFi connections to your devices so that these devices can communicate with each other, allowing you to have a file or media server supplying data, movies or music to your devices. The Ethernet and WiFi connections will also provide simultaneous connection to the Internet.

From a computer, if you configure both the Ethernet and WiFi connections to your router at the same time, the operating system (Windows) will normally use Ethernet and ignore the WiFi connection. It is possible, with the 'route' command to arrange for certain sites to be accessed over WiFi while other sites are accessed over Ethernet. For example, if you could configure the Internet connection to use WiFi, while access to a local file server could use Ethernet.

The term "wireless internet" is erroneous. WiFi goes only between devices (tablets, laptops, phones, etc) and the router. It does not go to the Internet.

To answer your question, with a wireless router you can Ethernet and WiFi connected devices accessing the Internet at the same time.

I hope this helps.

If you have a device with both wireless and ethernet connections to a router, whichever one is selected as your default connection type will be used. (never both at the same time)

If you mean at the router, I'll give you my LAN arrangement as an example. I have more than 2 dozen older computers (no Wi-Fi in any) that connect to my LAN (local area network) through a series of ethernet hubs (using ethernet cables that end at my combination Wi-Fi and ethernet router. Wireless devices connect to the wireless side of the router and all devices can connect with each other as needed. The wirless/ethernet router also connects to the modem and thus the entire ethernet and wireless network can share the internet.

I also have a second Wi-Fi/ethernet router used as a "range extender" that allows the ethernet and wireless network in an external building to also connect wirelessly to the LAN in my primary building.

Yes it will.

yes

The WiFi goes on standby
