Example 4: LAN (USB) Internet Connection and LAN (Ethernet) Private Connection
Many of the new cable modems today offer both Ethernet connection and USB connection. If you have only a single Ethernet connection you can use the USB connection and free your Ethernet connection to connect to your wireless router.
Figure 6 - USB with Separated Modem and Wireless Router
Figure 7 -USB with Integrated Modem and Wireless Router
Note: If you have a wireless router integrated with broadband modem, this method might not work, since some of the integrated modems will not work properly with both USB and Ethernet connections at the same time. If that is the case you will need to obtain a separate wireless router, access point, or wireless card (if using the wireless card method).
In this example, the Internet Connection is your USB connection, and the Local Area Network (Ethernet) Connection is the Private Connection.
1. Connect your broadband modem to your PC using a USB cable. If you have your Cable Modem or ISP CD insert it now. If Microsoft Windows can not find a driver for your Cable Modem download the latest driver from your cable modem manufacturer web site.
Tip: Examine your cable modem and write down its make and model. Then using your favorite search engine you can search for the right driver by keying you modem make and model and keyword “USB Driver Download”. (For example “Scientific Atlanta WebStar USB Driver Download”)
2. Open Network Connections Select the USB connection that you just plugged, right click on it and select Rename. Type: “Internet Connection” (Renaming the connection make it easier to identify the connection later).
Note: To open Network Connections, click Start ► Run; in the dialog box, type ncpa.cpl and click OK.
Tip: If you have multiple connections, and you are not sure which connection you just plugged. Unplug it, it will disappear, then plug it again.
3. Connect your access point to the Ethernet port of your PC. If you are connecting to a wireless router use one of the LAN ports, not the Internet port. If your access point is connected to a switch you can also connect to that switch.
4. Open Network Connections Select the connection from which you plugged, right click on it and select Rename. Type: “Private Connection” (Renaming the connection make it easier to identify the connection later).
Tip: If you have multiple connected connections, and you are not sure which one you just plugged, try to unplug the cable. The status of the connection you unplugged will changed from Connected to Network Cable Unplugged.
5. Refer to your wireless access point or router device documentation on how to change SSID and configure your device to use SSID (some times called Network ID or name) of “2HOTSPOT”.
6. If you are rewiring a router that was previously connected to your broadband modem (or is your broadband modem), you also need to login to the router and disable DHCP Server.
Note: After you disable DHCP if you want to access your router again, you will need to configure your PC with static IP using the router IP as the default gateway. If you are not sure how to configure static IP, you can reset the router to factory settings using the reset button to re-enable DHCP. Your Hotspot will not work properly when DHCP is enabled on the a router that is connected to your Private Connection.
Tip: If you need to regain access to your router, and don’t remember which numbers to use for static IP, there is a method that will work most of time: For Default gateway use the same IP address used to access your router configuration through a web browser. For Subnet mask use 255.255.255.0 and for IP address use the same IP as Default gateway except changing the last number.
7. If you are rewiring a router that was previously connected to your broadband modem, if possible change its Internet Connection settings to “Bridged Mode”.
