How to set up your laptop as a wireless server

If you run a meeting without a server or you are out of range of the server during a meeting, you can easily configure your own laptop as a server. The following information is a brief procedure on how to do this. Note that this configuration effectively works for meetings with a max of 30 other workstations connecting to your laptop.

Sub-Working group procedures while out of range of the server.

In many environments you will not be in radio range of the server, this will make document sharing within your meeting difficult. The following is a simple procedure to use your laptop as document repository, in effect making it a server to your meeting participants.

To avoid conflicts with the 3GPP2 mobile LAN IP addressing, here are procedures to follow to ensure compatibility when within range or out of range of the server. If a user has received an address from your working group and roams within range of an Access point from another meeting, he will not have a duplicate IP address and will still be able to access other working group servers without releasing the IP address. They will only need to change their wireless profile.

To totally avoid conflicts and avoid using a DHCP server you can install NetBEUI protocol. This will enable users to see your shared folder from "Network Neiborhood," providing they have bound NetBEUI to thier network card as well. You can have both NetBEUI and TCP/IP bound to the same card.

Using your personal Laptop as a server:

Create a Profile with the Orinoco/WaveLAN client manager or other 802.11b product for peer-to-peer mode, name the network "TSGxWGx," where as "x" is your group and working group. (Peer-to-peer is the term from the Orinoco/WaveLAN product, terms may be different for other products.)

Share a folder on your PC or install a FTP server on your machine. There are many shareware/freeware apps for this as well. FTP will not work using NetBEUI. (File & Printer sharing for Microsoft networks will need to be enabled.)

Find a DHCP server to install on your machine. There are shareware/freeware applications that work just great. The one I used was Magik DHCP. The URL is: http://www.khouzam.net/dhcp (This program works on all Windows operating systems.)

Use the corresponding Static IP address for you group. (In the table below)

Configure your DHCP server:

The following ranges will allow for 30 clients to receive an address, from your computer, for your meeting.

The subnet mask is 255.255.248.0 for all configurations!

Here are ranges to use:
TSG-A Static Address:  Set Range for:

TSG-S Static Address:  Set Range for:
  SWG1 10.10.246.13 10.10.247.131 - 10.10.247.160
  SWG2 10.10.246.14 10.10.247.161 - 10.10.247.190
Ad Hoc & Special Groups Static Address:  Set Range for:
  SWG1 10.10.246.15 10.10.247.191 - 10.10.247.220

Client Access

Within the 802.11b card, Configure the client to connect to a peer-to-peer network and use the network name you used when creating your peer-to-peer network profile.

Upon booting, the user should receive an IP address from your workstation and then be able to connect to your shared directory or FTP root, depending on your choice of configuration. If you choose to use NetBEUI, IP addressing will not be an issue.

Notes:

I have found that Orinoco cards will not release an IP address when switching between network profiles. However, other cards I have tested will release the IP address when switching profiles.
