Hi Nick, I am sorry but I have been misunderstood. Actually the same USRP2 that is not working and cannot manage to connect with one of my laptops, it actually works very well with one of my other laptop that use a UHD_003.004.000-325-g7e296167 revision of uhd. So I believe ethernet works just fine. Maybe the ethernet jack of my laptop does not operate that good. You think that one might be an issue?
