@Ewan15 Thanks for your reply was trying hard not too draw to much attention to it all! The 2.5Gb/s nic interface's can sometimes be that way when timing becomes that bit more critical between devices, so everything needs to be done just to give the helping hand, thought i would have had some issues with the son's 10Gb/s interface but no turned out to be rock solid on both the 10 and the 2.5, must just have hit that lucky streak!
