Hate to say it, but your all wrong. RC is correct though, you you can use router ports. I am in the process of upgrading that side of things. Near my roter I have two switches, an access poit, a USB serial server, a slingbos, a skype handset base station. Plans include a home automation server and RAID array.
Further away, there is a wirelss all in one printer and a wired laser printer. I'm working on adding wired ethernet for IR repeating and gigabit ethernet for the RAID array.
I have this:

Here are the instructions for "Client mode"

In "repeater" mode, you can use the Ethernet port as well.
Usually, these types of devices are called wireless repeaters or access points. They allow all sorts of configurations such as with two, you can make a Ethernet to wireless - wireless to Eternet link
They repeat a wirelsss signal and the Ethernet port can be used for a device,
They act as an access point for wireless. I have a router configured to be that, but it doesn't have the other modes.
or what you need, they connect a wireless signal to Ethernet.
You will have to determine if you have wireless b, g, n or ac, Mine covers b & g only; hence it's on the way out.
I actually, just used it the other day to access my wired network wirelessly, but I kept it in repeater mode.
You can use a cheaper device, called a wireless print server. These usually use USB.

There is a whole bunch of products here: **broken link removed**
I have used these types of devices many years ago for a USB DeskJet. I guess I was an early adopter.
Same thing with the repeater. I know of no one that has one. With it, I have living room, porch and outside access.
