I travel all over the UK in my work, I tend to stay in cheap B&B places with no wifi but looking around there are residential properties nearby where BT hotspots exist, I am a BT customer so I can use these for free if I login, but the signal is not good enough for my devices.
What is needed is an router, configured as an client to pick up the wifi signal and then make it available to my devices via wifi and cable (for my Roku).
When I get back home I want to use the same router to use WAN port for cable connected Internet.
Thus far this has been a total failure, I can see the wifi hotspot signal on my Linksys Wrt32x when I scan for it and I can get an IP and DCHP lease for it, but the IP changes so I can't hard wire any route into it, other than it is always a 100.x.x.x/16 network.
Are there firewall settings I need to change?
How would I configure the interfaces in OpenWrt to make this work?
I can see the connection as a client is working on the OpenWrt status page
The Wifi Hotspot is transmitted without encryption and on a Laptop or phone would take me to my BT Login page, but that never happens with devices connected to the Wrt32x whether by cable or Wifi.
Do I need to configure some sort of route from 192.168.1.0 to 18.104.22.168 or is there more to it?
Ideally I would like the thing to be plug and play, so that when I return home I just plug in the Wan cable and it figures is out, but if I have to connect and disable something I am OK with that.
