I had to do some rewiring of my network and unplugged everything from my router. After which B2 didn't come online anymore.. The router shows an IP for it and the correct MAC-address, but ping command says "Destination Host Unreachable" and ssh "No route to host".
I've tried both lan ports, tried the rescue system, also as last ditch effort I tried re-installing everything.. to no use.
So what gives?

Is the network chipset busted? ..or what. The B2 is around 5years old..
I have netwjork pico wlan usb thingy.. can I use that to network?
Hälp!
