Hi Martin, Currently i'm using a SAMR21-XPRO because OpenMote doesn't provide tranceiver's drivers. Anyway this issue is strange...

Hi Alessandro,
Hi Martin,
My name's Martine 
Currently i'm using a SAMR21-XPRO because OpenMote doesn't provide tranceiver's drivers.
Sorry... I meant the OpenLabs radio adapter for the Raspberry Pi [1]. OpenMote, OpenLabs... either to confuse ^^"
Currently there are two (predominant) ways to set-up a border router between RIOT and the Internet via Linux: either use a Raspberry Pi with an OpenLabs-type device mounted on it using this [2] tutorial, or by flashing the gnrc_border_router example to another node [3]. Which one did you went for? If you went for the first: please try the second (if you have another radio-equipped device).
Anyway this issue is strange...
Hope my reply could provide some clearance.

Also could you maybe change your subscriber settings to non-digest subscription or at least keep the discussion context, please? I know that this causes more mails in your Inbox, but with some clever filtering this shouldn't be a problem. On the other hand, the digest format makes following our discussion very hard, since it shreds the thread structure (see [4]). I'm not even 100% sure what you are talking about in your reply.
Cheers, Martine
