How To Share Internet Access

From Catherine Roseberry, for About.com

While on business trips or attending conferences, there may not always be multiple Internet connections available for all participants to take advantage of. Using a Wireless Access Point/Router you can share Internet access with co-workers during meetings or conferences in locations where there is just one Internet connection such as a hotel or conference centre. This will work in locations which offer Internet access connections through an Ethernet connection.
Difficulty: Average
Time Required: 20 mins
Here's How:
  1. Connect your laptop to the location’s Internet service. You must establish a connection in order to gather information for later use.
  2. Collect technical specifications of the connection. Use Ipconfig/all in Win XP & 2000. Winipcfg in Win98.
  3. Information to Record: Physical address / IP address / Subnet Mask / Default Gateway / DHCP server / DNS servers
  4. Start up the Wi-Fi AP/Router and change the laptop connection over to it.
  5. Open AP/Router configuration screen. The manual for it will provide the IP address and log-in info.
  6. Find the screen to change the wired connection information collected above. Check under Advanced or WAN.
  7. Enter the following information for IP address / Subnet Mask / Default gateway / DNS server / DHCP server.
  8. Save changes and re-start the Wi-Fi AP/Router.
  9. Disconnect laptop from AP/Router and connect AP/Router directly to Internet service.
  10. Connect your laptop to the AP/Router and connect to the Internet.
  11. You can now share Internet access with other laptops or handhelds using the Wi-Fi AP/Router.
Tips:
  1. Do not change any information in the WLAN or Wireless tabs of the AP configuration screens.
What You Need:
  • Ethernet enabled Internet connection in the location.
