Sharing Dial Up / Wireless Modem Internet Connection to WiFi Access Point

In general, internet connection can be accessible via various modems such as USB Wireless Modem, Dial Up Modem and ADSL Modem. Most WiFi access points or routers are designed for ADSL modem with WAN and Ethernet ports only but unfortunately do not have a USB and RJ11 landline jack so you won't be able to directly connect a USB wireless modem or dial up line (RJ11) for sharing internet connection on them. You may be wondering if you can still share your USB or RJ11 dial up internet with others via a WiFi access point as illustrated below without switching to ADSL modem with WAN port.

Sharing Dial Up / Wireless Modem Internet Connection to WiFi Access Point

The answer is definitely yes, nothing is impossible. All you need is just a computer with working internet connection access via either a dial up modem or USB wireless modem which you want to share with other computers around you through the WiFi access point / router. This computer will be named "host computer".

  1. Connect and set up WiFi access point
    Connect your WiFi access point to host computer via the RJ45 Ethernet port on both sides, you will need RJ45 cable to do this. Be aware not to connect to the WAN port but the LAN port. It could be mistaken because they are both RJ45 jacks.

    Your desktop system tray may show a popup balloon notifying you of successful connection: "Local Area Connection is now connected". If you cannot connect to the access point, make sure you have enabled the Local Area connection before (enable it by accessing Control Panel > Network Connections > right click Local Area Network > Enable). Next, open Internet Explorer or Mozilla Firefox and type in the address box and press enter. What we are trying to do is to open the web configuration control panel of your WiFi access point. Please note that is the default IP address which most WiFi access points and routers used, this IP address may varies by brands and types of WiFi access point you purchase and it is usually printed at the back side of your device with both default username and password. Enter this username and password if prompted on screen.

    If you cannot access this IP address (the internet browser shows a blank page), you may try to reset the access point (push a small pin to a small hole at the back of the device and hold it for about 10 seconds) and then try to open again or refresh the browser. If you have successfully accessed the web configuration control panel of your WiFi access point, then find the DHCP setting and turn it off. If you encounter difficulty to locate the DHCP setting, read the manual book. DHCP stands for Dynamic Host Configuration Protocol which is used to automatically manage and assign IP address to every computer connected to it. We need to disable this DHCP on access point side as it may clash with the DHCP of Internet Connection Sharing from host computer, there should be NO 2 or more DHCP servers on a network server.
  2. Connect and run either USB wireless modem / dial up modem
    Connect USB wireless modem or RJ11 landline jack to your host computer and connect to internet as you usually did. Try to browse any internet page to confirm that you have a working internet connection. There must be a name which you have given for this connection before. Remember this connection name. If you cannot connect to internet, resolve this issue first before proceeding to next step. You can test the connection with ping command (just run the command prompt and type in: "ping -t" without double quotations) Successful pings will show you replies from other side.
  3. Set up your host computer
    Go to Control Panel > Network Connections. Switch to Details View (click View > Details) to verify connected status of each connections. Right click your active internet connection name (the one i ask you to remember in step 2) and click Properties. In the properties box, go to Advanced tab.
    Enable Internet Connection Sharing

    There you will find Internet Connection Sharing checkbox with these words: "Allow other network users to connect through the computer's internet connection", check the box and leave other boxes below it unchecked. If a drop down list show up to ask for your "Home networking connection", click on the box and select "Local Area Connection" (the name of your WiFi access point connection). This will enable the Windows Internet Connection Sharing (ICS) to WiFi access point.

These 3 steps conclude all you need to do to share a dial up / wireless modem internet connection to WiFi access point. Test connecting other computers to the WiFi access point and check the internet connection. Please note that sharing dial up internet connection on a big network with lots of computers may slow down the internet access speed as the already-low dial up bandwidth will be divided among computers. Your host computer must always be turned on too as it is acting as a server where DHCP and internet connection sharing are run.

Good luck folks, happy to share with you.
