Best Device/Solution to get unsecured wifi to Private Network

[pistolpete_1980]

Hi. I'll keep this simple.

Scenario:
My landlord provides free wifi via an unsecured public network. As of right now I connect my iphones, and Laptops to this unsecured network for internet access.

Goal:
I would like to have my own network but I want to be able to feed his free wifi internet into my network.

Stipulations:
I do not have access to his router via ethernet connection, I can only gain access through wifi.

What would be the best most efficient way of getting the free wifi internet into my own network? Is there a router that can connect to a wifi hotspot then transmit a new wifi to a seperate network?

I do the same thing, only difference is my landlords Wi-Fi is secured. I use a TP-Link WDR4300 with one 2.4 GHz and one 5 GHz radio with OpenWrt. A wireless client can be configured in a number of ways, only some require administrative access to the remote access point. One radio connects to landlords Wi-Fi, the other broadcasts an access point for my devices, and Ethernet devices also have Internet access through it.
