|Connecting a second router is more work and requires more know-how than using an AP as Richard59 recommended. |
The only thing is, a router may very well be cheaper than an AP in which case, if you know your way around computers reasonably well, you may want to use a router instead. If you do some price comparing and find you can get a wireless router cheaper and want to do that, you will first want to click on my name above in this response and read my “how-to” guide titled, “Add a second Router to your LAN”
You'll want to pay attention to the scenario where you're just adding it to your existing network by interconnecting the two devices "LAN port to LAN port"
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
