Will the pc be acting as a hub or do I need to setup the pc so that it can forward the requests.
Do I need to install some drivers on the pc for the WE5100 chip?
QuoteWill the pc be acting as a hub or do I need to setup the pc so that it can forward the requests.Yes and yes.
But you will not have a DHCP server, so have to set IP addresses for both.
Why would you want to do this ?If both the PC and the Arduino are connected with DHCP to a hub, they can connect to each other without problem.It is much easier with a hub as the 'glue' between the two. If the hub is connected to internet or not, that doesn't matter.
