Thanks for the patch Dan. The modem seems to connect, it gets an IP
address and DNS servers, but there is no connectiviy. I cannot resolve
any names, I cannot even ping the gateway (I can ping my own ip
address)
There are also some warnings and errors that may be important. Find
here the log: http://pastebin.com/JC9BALPs
Thanks
