I'm on a bus4you with destination Oslo for a visit to Opera Software's main offices. The bus has wireless internet. That's good, I've been reading webpages on map-reduce, distributed filesystems and other interesting stuff the whole trip.

The bus driver mentioned that the network sometimes stops working, and requires a restart when that happens. It happened, and after confirming with one of my co-passenges that they too had trouble, I went to tell the driver.

No problem, he said, I'll restart it. And to restart it, he pressed a button marked "WWW".

So, if the WWW doesn't work for you, now you know where to find the button with which it can be restarted - just find the nearest bus4you bus! :-)
