Thanks but that just adds to the confusion, I do not want to connect wifi.. I just want to know how to bring up a (wired) network card. My router lost power then when restored obviously gave out different IP address, for my PC, previously I used ifup eth0 but things have moved on, I just rebooted but thought I would ask what the latest command to use today is. I did spent some time looking online but there seems to be lots of various options.
