Non-free firmware is included in the deployment syste Some years ago, I had a defective cable which had only problems when using larger ethernet packets. Pinging worked very well, but when the machine started using NFS and NIS, the whole networked stalled because of the larger packets. IMO only the packages size should influence if the network is working or not. I'm not aware of any reason that software or a different driver could "fix" a defective cable. -- regards Thomas
