Hi Graeme, I think that 1) and 2) was done correctly in my case. For 3), I'll check dmesg. For 4), I found the thread in 2013: http://lists.etherlab.org/pipermail/etherlab-users/2013/002074.html But I can't get the attachment since I'm not in the etherlab-user mail list. Is there any other way to get the attachment?
Thank you for your response.
