The symptom — LAN file sharing works but Internet stops when those machines use a "static" address while DHCP clients work — usually points to configuration mismatches rather than a defective Intel 945Gcnl board. Key causes to consider are how the ISP delivers the address (a single public/static on the modem/router, PPPoE credentials, or MAC-locked service), incorrect gateway/netmask/DNS on the manually set address, or a driver/firmware issue on the onboard NIC. This expands on the diagnostic direction raised by , and the router/OS angles flagged by and .

Useful CLI checks (collect once and compare between a working DHCP client and a failing static client):

ipconfig /all
ping <default gateway IP>
ping 8.8.8.8
nslookup google.com
arp -a
route print

If the gateway ping fails while local peers respond, the problem is routing/ISP side (PPP oE or MAC binding). If the gateway responds but external pings fail, check NAT/ WAN setup on the modem/router. Practical fixes that follow from those outcomes: configure the ISP-provided static on the router WAN and leave LAN on DHCP (or use DHCP reservations), clone/register the router MAC with the ISP if they bind addresses, update NIC/chipset drivers and router firmware, and test with a USB Ethernet adapter or a Linux live-boot to rule out driver/hardware. Note the security warning: assigning a public static IP directly to a PC exposes services unless a proper firewall/NAT is in place.

We need a lot more information than that to work with.

What windows version are you using?
Is your broadband modem set to DHCP or staticIP?
Are your computers set to DHCP or staticIP?
What things have you already tried?
Do you get no internet connection at all or do you get error messages?

Dig into your router settings, and assign a static IP to the machines. Then, retest, and repost.

Static IP addresses are configured at the operating system level, usually when you install the system. The board itself has nothing to do with the IP address the network ports will use. As mentioned, you need to see what address range your router is configured to use for dynamic addresses, and then select one in its subnet that is not in the dhcp pool. Example, on my network, which is to (254 being the router address), addresses thru are reserved for dhcp (dynamic) addresses, so my workstation and other static devices are given addresses under , such as , , etc.
