Local-only networking while two machines can see each other but one cannot reach the Internet usually means the LAN is fine but the path to the gateway or beyond is broken. and described that scenario; suggested Internet Connection Sharing (ICS). ICS is only appropriate when the modem is connected directly to a PC. When a modem is connected to a router and both PCs attach to the router, the router normally handles NAT and DHCP — enabling ICS in that setup often causes address and gateway conflicts.

Start with basic diagnostics from the problem PC to locate the fault:

ipconfig /all
ping <DefaultGateway>
ping 8.8.8.8
nslookup example.com 8.8.8.8
tracert 8.8.8.8

Interpretation hints: if the adapter shows an APIPA address (169.254.x.x) DHCP failed; if the gateway shown by ipconfig does not respond to ping, the link to the router is broken; if the gateway responds but 8.8.8.8 does not, the issue is upstream (router/modem/ISP); if IP pings work but nslookup fails, DNS is the culprit.

Check the router itself (use the gateway address from ipconfig to open its admin page). Confirm the WAN/Internet status shows a valid public IP, that DHCP is enabled for LAN clients, and that no access control or MAC filtering blocks the non-working machine. Verify the modem cable is in the router’s WAN/Internet port (not a LAN port) and that router/modem status lights indicate a live connection.

Quick remedies that often fix this class of problem:

ipconfig /release
ipconfig /renew
netsh int ip reset
netsh winsock reset

Reboot after the last two commands, power-cycle modem and router, swap Ethernet cables or ports, temporarily disable third‑party firewall/AV, and update the NIC driver. Avoid running ICS on a PC when the router is already providing NAT/DHCP — that configuration commonly creates the symptoms described.

Hi guys

ICS or Internet Connection Sharing. Try the following : The computer that has the modem connected to it give it an IP address of
and the other desktop an IP address of and set the default gateway to this means that it must look at the computer with the modem for access to the internet.

Then on the computer that has the modem, open your network connections and right click on you internet connection and got to properties and then Advances then tick the box to allow ICS on this connection and then makes sure Local Area Connection is selected.

I have five PC's using 1 dialup connection to connect to the internet using ICS.

Hope this helps
