Thanks a lot!

Seems, that this fd11:22 only shows up randomly. If it's there, it works, as you wrote.

Are there know startup issues? Maybe "power supply"?

Hi,

It looks like you are missing the IPv6 address from the Wpantund interface (Default: on-mesh prefix "fd11:22::/64"):

> ipaddr
fd11:22:0:0:4567:cc67:5831:d8a3
fdde:ad00:beef:0:0:ff:fe00:8000
fdde:ad00:beef:0:c785:680f:db44:e436
fe80:0:0:0:9895:490:5998:65a7
Done

Done

Without the fd11:22::/64 address, you will not be able to reach internet through the Border Router. You can try power cycling the NCP, and then run "sudo wpantund" to bring up the NCP again:
