The Linksys NAT router has a built-in *switch* that will take full advantage
of full duplex for any machines connected to the LAN ports of the router or
if another standalone switch is connected and machines are connected to it.
Most NIC(s) will work in full duplex mode in that situation.

If the machine is compormised with malware, you need to find it.

What's wrong with the Linksys NAT router as the gateway device and provides
protection from the WAN for the LAN?

I don't think you need to be using Linux to do anything here IMHO.

I'll have to question the whole laptop thing period.
