Thanks guys, to do this ssh, do I need a wifi router with active connection to the web?

My only option for web browsing is currently to tether using my trusty N900, so that presumably wouldnt be an option for me...

However, I do still have a BT homehub router, which i guess could still just serve as a LAN, which might be good enough to let me do a SSH?

Hmmm, i must try...
