I have a Windows XP PC, a Windows 7 Laptop and a wireless router ( Rosewill RNX-EasyN4). I put an additional PCI Ethernet card into my PC, so it now has two network ports (the first being the built-in motherboard Ethernet port). I am trying to do something like:
[PC] <---- Ethernet ----> [Modem WAN] <---- Wireless ---> [Laptop]
I am not good at networking so I might be missing something obvious here. I am trying to figure out if I need to use DHCP (Obtain IP Address automatically) or specify the IP Address on the PC. Also should I specify a static IP for the modems WAN port? (I think I can do this in the configuration.)
Note: No internet connection in my attempt above. The built-in Ethernet port of the PC is unused.
The following is what I have tried so far: I first tried to verify if the new PCI Ethernet card is working. I took off the internet connection to the PCI from its regular built-in Ethernet port and put the cable into this new port. The PC had internet.
I tried to establish a wired connection between the PC and the Laptop. For this I set both the PC and the Laptop to static IPs and connected them using a crossover cable. This worked.
So if I need to connect to my wireless router from my PC should I set it to DHCP or a static IP? Also what do I need to configure my WAN port, i.e. DHCP or static IP?
