For wired connections users must fill out an IP address request form for each machine they want connected to the network. You will need to enter the hardware (MAC) address for the Ethernet card being used. We use DHCP to provide IP addresses for laptops, whether it is a wireless or wired connection. We will assign static IP addresses for desktop and server machines.

Columbia University Departments should contact the Information Systems or Information Technology group within their department. If you do not have one or if you are unsure if your department has an IT group, contact your business office. Hospital Departments should contact the New York Presbyterian Hospital Helpdesk and make a new connection request.

The CS Department's wireless network is configured as part of the campus wireless network. So once your machine is configured to work on the department's wireless, it should work most anywhere on campus. For further information on setting up wireless access, consult the ACNS Wireless Web Page. For information on setting up wireless access from a Linux machine, consult the Netsec webpage, "Using the CSU VPN in Linux".

Yes, provided that you have brought your laptop into Computer Services in Tec 21E for certification that it meets security guidelines. Computer Services checks and updates such laptop computers as necessary. Remember that you cannot unplug an office computer to connect a laptop ? even a laptop that has been certified. Can I connect my own laptop to a projector without connecting to the network? I have my own laptop that I use in class, but I connect it only to one of the school's projectors.

Probably. Any wireless receiver supporting the industry standard 802.11b or 802.11g protocols should work. However, in rare cases, we have found wireless receivers which had compatibility issues with the computer upon which it was installed.

Florian Xaver postet a list of intersting DOS network links to the FreeDOS mailing list: http://www.freedos.org/freedos/news/technote/157.html. Thanks a lot!

You should try increasing the switch time using "multinet changeparams -switch ". Also make sure the wireless zero config is turned off, and you are able to connect to the network. A way to check for connectivity is by following these steps. Firstly, turn off the MultiNet service, using "net stop MultiNetService". Then, turn on Wireless Zero Configuration, and try connecting to your network. Once you are done testing, turn off Zero Configuration, and turn on the MultiNet service.

No. You are not permitted to connect any 'network infrastructure' equipment to the network, therefore it is not possible to connect more than one computer.

Generally, with the equipment we're using - you need to have Line of Sight (LOS) to someone on the network already and they probably need to be within a few miles of you even with a clear LOS. Once you connect to them - you're on the network and should be able to connect to anyone else on the network regardless of how far away from you they are.

Departments can complete a TNS Network Service Request online. TNS will do a site survey and determine the optimum locations for public wireless access and install service as available funding permits. Departments wishing to arrange for wireless service in department-controlled classroom space or public areas should complete the online form.

Your computer must have a wireless network card installed. Computer manufacturers typically indicate this by saying their equipment is WiFi enabled, or that they support 802.11b or 802.11g wireless networks. On a Macintosh computer this is often referred to as an airport card.

Yes, you can connect more than one server. You connect two servers with a cross connect cable, or you can connect multiple server with a switch.
