I'm moving into a new apartment at the end of the month which offers excellent (fiber) Internet access included in the rent. The problem is that the apartments aren't wired - it's WiFi only. I'd obviously like to use this instead of paying $80/month for Comcast, but I'm having trouble figuring out how.

One issue is that neither of the desktop systems has a wireless adapter. The other is that I'd like to be able to share data amongst all my devices without sharing it on the public network (or burdening that network with my LAN activity).

Current network configuration is:

  • Cable Modem
    • TP-Link TL-WDR3500 Wireless Router
      • Wired access to:
        • Desktop PC
        • Home Theater Gaming PC
      • Wireless access to:
        • Laptop
        • Cellphone
        • Smart TV
        • Console
        • Guest Laptop
        • Guest Cellphone

Desired network configuration is:

  • WiFi
    • (???)
      • Wired access to:
        • Desktop PC
        • Home Theater Gaming PC
      • Wireless access to:
        • Laptop
        • Cellphone
        • Smart TV
        • Console
        • Guest Laptop
        • Guest Cellphone

I have three ideas so far:

  1. Configure one of my desktop systems to connect to the WiFi and share its connection via ethernet to my existing router, from which I can then share it to everything else via a private mixed wired/wireless network.

  2. Buy a device (what kind?) that can connect to the WiFi as a client and then share the connection, either on its own or with the help of the router.

  3. Buy wireless adapters for both of the desktop systems and use an ad-hoc network for filesharing. (How?)

Option 2 would be my preference but I don't know what kind of device will do what I want. My router won't do it, nor will a repeater/extender, and I'm not sure about an access point.
