Windows 10: Need to transfer files from Wired Desktop to Wireless Laptop

Happy Thanksgiving to everyone.

This is the setup I have connected at the moment, Dell Optiplex 790 connected to my AV Receiver via 3.5mm to RCA (audio), connected to my TV via VGA Cable and connected to router via ethernet running Windows 10 Home Premium.

Also running a Dell Inspiron 17R 5720 via WiFi running Windows 10 Enterprise.

I don't have any flash drives or portable hard drives laying around to transfer files over, so how do I transfer files wirelessly via the network.

Wireless laptop - wired desktop - internet

I'd recommend a wireless router. Plug the desktop into the router via wired cable. Plug your Internet device into the router. And then the laptop will have wireless Internet access.

Most desktops have wired integrated. Most laptops have wireless integrated. All you should need is a router and maybe some cables. Wireless routers start around $50 USD.

 

LAN with desktop wired to router and laptop wireless

This is probably has to be as simple as it gets, however i am having major difficulties.
I have a desktop computer running Windows 8.1 & a Laptop Computer running also Windows 8.1
What i need is a LAN between the two of them.

The lan would be required to play games and file transfer. I have partially managed to get the file transfer to work, using this guide: Tom's Hardware: For The Hardcore PC Enthusiast
However the actual lan does not work. I can not get any games playing. Maybe because i have automatic ip address on both computers?
When ever i made lan parties at the house,i set everybody's computers with a specific IP.So when i am in game,i just open console type :Connect IP and i am in game.
Can i make LAN with automatic IP? And if so,how to do so?

Another issue is how to integrate My Printer into this LAN?
I have a printer that i have it connected to my desktop. The printer does not have a network card on it. So no it is not ethernet capable. It's an old model,connecting only via USB 2.0
I want to be able to access the printer from my laptop.

 

Windows update on wired desktop disables wireless

I have a Windows 10 desktop on a wired connection in my home network.

Following the forced update KB3211320 yesterday, 1/25/17, none of the wireless devices I use on my home network have access to the internet. This includes a Windows 10 laptop and a couple of Android devices. If I power down the wired desktop that received
the update, all the wireless devices return to working as normal. All of my wired devices on this network appear to be unaffected.

Any suggestions where I should start looking? Nothing changed other than this update.
