I have a desktop the connects to the internet via a dial up connection. I alsohave a laptop with a USB (airlink) 802.11g adaptor.

I want to share files/internet connection between the desktop and laptop wirelessly. I have a Belkin 802.11g router on the desktop.

Since I have no DSL router I have plugged the WAN connection on router into the NIC in desktop. I then set up a network on my desktop using the "wizzard". I set the TCPIP protocol to obtain IP automatically and obtain DNS automatically.

I then set up a network on the laptop with the wizzard. It was set to connect to internet from another computer and to share files. I also plugged in the USB adaptor for wireless g

I have shared folders on both systems, put stuff in my shared folder, and tried to connect to internet from laptop WITH NO LUCK. Shared files do not appear, I can not see the other computer in "my network" and no internet connection sharing to the laptop.

Does anyone have advice on next steps? I am forced with the dialup connection and will try getting another USB adaptor and just use those w/o router. I wonder what will happen?

Thanks

As noted by , the core issue is the router and the PC both trying to act as gateways/DHCP authorities; that separates the two machines into different networks so shares and ICS will not cross. The practical fixes are to make the Belkin act only as a switch/AP (LAN ports, DHCP off) so the desktop can provide Internet Connection Sharing, or else to bypass the router entirely and create a direct wireless link (ad-hoc or a second USB radio on the desktop) so the desktop can be the gateway for the laptop.

Recommended checklist (apply in this order):

  • Put the desktop on a router LAN port (not the WAN port) and set the router to AP/switch mode by disabling its DHCP server and giving the router a static LAN address in the same subnet (but outside the desktop’s DHCP range).
  • Enable Internet Connection Sharing on the desktop’s dial-up adapter and let it assign the gateway/IPs (Windows ICS commonly places the shared interface at 192.168.0.1 — confirm on the host).
  • Configure the laptop to obtain its IP/DNS automatically (or use a static IP in the shared subnet with the desktop IP as gateway).
  • Temporarily disable firewalls on both machines (or at least allow File and Printer Sharing and SMB) to verify name/SMB visibility, then re-enable and add rules for SMB/ICMP as needed.

Diagnostics to collect and tests to run (these outputs clarify routing/DHCP problems):

ipconfig /all
route print
arp -a
From the laptop: ping <desktop IP>, ping <router IP>, ping 8.8.8.8
From the laptop: net view \\<desktop IP>   (to list shares by IP)

If the Network Neighborhood is blank, accessing shares by IP (\192.168.x.x) usually works. As recommended, include the IP/DHCP/router settings and firmware if further troubleshooting is needed. Security note: sharing across wireless exposes the desktop to the LAN—enable password-protected sharing and secure the wireless link.

To get to the root of the problem most quickly, you should give us all of the IP configuration settings for both computers and the router. If we can review those configurations we'll have something solid to go on.

Hello.

I think That´s the Fault.

A router works connecting networks, so if you connect your PC in the WAN connectión, it is in a different network than the one that the other computer is.

Routers use to have LAN connectións, usually four of them , you must conect yor Desktop to that connectións.

Then , If you´want to share the desktop Dial Up connectión, you have to disable DHCP on the router and Assign static Ip Adresses to computers, because the Desktop have to act as gateway to the laptop, by default, the router when assings by DHCP will reffer his own IP as the gateway for the computers.
