Well how do you have a household without broadband? You skive off free wifi and use your huge 6 GB cellular data on your $50 phone plan is how you do it. Since Vodafone has just upped the data on my plan to 6 GB for no extra cost.
I am connecting to the wifi using a Ubiquiti bridge to allow my regular desktop computers to work over the wireless. I started working with it in Bridge mode. This essentially makes each computer on your network an address on the remote network. Its main disadvantages are that your computer is on that network and therefore subject to the traffic on the rest of that network – and vice versa.
I then had a go at setting it up in Router mode. The Nanobridge needed to be updated to the 6.0 firmware a few days ago when I first started playing with it, and then once I set the router mode it handed out local addresses using its own DHCP server, but it didn’t actually work, until I went back through the settings and saw the NAT box needed to be ticked. Once that was sorted it all started working as expected.
