Frequently
Asked Questions (FAQ)
-
My VPN Client randomly drops its connection when
I do not want it to disconnect. Can I prevent this
from happening?
- XP Firewall - connection dropping after
a few minutes
Those using the Cisco VPN Client, on a system
running Windows XP, with the Firewall feature
enabled, may experience timeout problems (your
session may disconnect within 5 minutes) if the
following type of traffic is not allowed to pass
through the firewall: UDP port 500.
Any customers using a home router or "NAT"
(Network Address Translations) box* should not
experience any problems whatsoever.
*Devices that are used to share Internet connections
within the home - connecting to Cablemodem services
(e.g. Cogeco) or High-Speed DSL services (e.g.
Sympatico) - from manufacturers such as SMC, NetGear,
Linksys, D-Link and Microsoft.
Changes required to avoid timeout issues:
- Start->Control Panel->Windows Firewall Under
the "General" Options Tab, ensure that the
"Don't allow exceptions" is NOT checked).
That is, you DO want to allow exceptions.
- Next, select the Exceptions Tab
- Select "Add Port"
- Specify a Name for this exception, in the
"Name:" field (call it anything you like.
Example: UDP500)
- Specify 500 as your Port number
- Select UDP
- Select OK
- Select OK again, to close the Windows
Firewall window.
- We have also had cases where
the wireless software for your wireless LAN card is
outdated. If you continue to experience
disconnects after applying the above fix, it is
suggested that you update your wireless LAN drivers
on your PC or laptop.
- What
is the musm-wireless network?
The wireless network is an extension of MSUM's wired network
infrastructure, which provides increased mobility and
flexibility for campus network users. The network consists
of a number of 802.11b and 802.11g compatible wireless
access points throughout campus.
- What does MUSM-Wireless allow me to do?
Students, faculty, and staff can use the
MSUM-Wireless
network to access the Internet and MSUM resources,
such as
e-mail,
without having to plug into a wired jack.
- Can I use any Internet application I have on my
computer?
Yes, although network bandwidth is regulated for peer-to-peer
music sharing programs. You are advised not to set up
shared folders without passwords. We also recommend having
antivirus software and firewall software installed on
your computer.
- Who can use this service?
Any current student, faculty or staff member with an active
Dragon Mail ID can use the wireless network. You must know
your password. Community patrons are not granted access.
Visiting presenters and scholars can use the wireless
network but need to work with the appropriate college
technician to get it set up.
- Is wireless access available in the residence
halls?
Yes it is. However, this
access is not part of the MSUM-Wireless
Network. The wireless access in the residence
halls is part of the GoMoorhead Network. Students
in the residence halls must have a Dragon ID and PIN to
access the GoMoorhead MSUM Wireless system.
- What are the requirements for using MSUM-Wireless?
You must be a current student, staff or faculty member
with an active Dragon Mail ID.
- How do I set up MSUM-Wireless?
Information on requirements for use and instructions on
how to set up MSUM-Wireless are provided on the MSUM_Wireless web site at
http://web.mnstate.edu/it/wireless/
- What hardware does MSUM-Wireless require?
To use the wireless network, a laptop computer or other
portable device is needed with 802.11b or 802.11g wireless
capabilities.
- What operating systems are compatible?
Supported operating systems include Windows 2000 or newer,
and MacOS 10.2.8 or newer.
- What kind of wireless card should I buy?
Any 802.11b or 802.11g network card should work with the
MSUM-Wireless network. 802.11g cards are backward
compatible and will work with 802.11b access points you
may have at home and vice versa. 802.11a wireless cards
will not work because they operate in a different frequency
range not compatible with the MSUM-Wireless network.
- Will my built-in wireless card work?
Some computer companies offer built-in products with laptops
and handheld devices as an optional feature. As long as
the products are compatible with the 802.11b or 802.11g
standards, they should work with the MSUM-Wireless
networks, though performance may vary.
- Do I still need a regular (wired) Ethernet card?
Generally, the answer is yes. Most mobile users will want
to use their computer on the wired network where available,
in addition to the wireless networks. Wireless makes a
great choice when the need for flexibility and mobility
is required and also for basic Internet activities, but
it is not as desirable when transferring large files or
performing many simultaneous network activities.
- Can I set up a wireless network?
No.
Setting up wireless access point on campus (non
residence halls) is PROHIBITED.
Wireless technology is easy to deploy but is also easily misconfigured and can interfere with other MSUM provided
wireless access devices. In addition, access points can
act as routers or DHCP servers if configured incorrectly,
which can disrupt service to other network users. They
also can compromise security and privacy, because anyone
within range of an unsecured access point could collect
traffic. Essentially, open wireless networks allow unauthorized
access to the university network resources.
If wireless access is not available in an on campus area and
you feel it should be, contact the MSUM IT department.
Issues of security and privacy eclipse other issues,
because anyone within range of an unsecured access point
could collect traffic. Any port that
is found to have an unauthorized access point attached
will be shut down and disciplinary action will be sought.
- How secure is the wireless network?
Wireless network security is a serious issue. Wireless
is not only a shared medium, but also a medium that is
broadcast via radio waves. Therefore, anyone with a wireless
card could monitor network traffic, which could include
passwords and account numbers, unless traffic is encrypted.
MSUM does use encryption via the use of a CISCO VPN
Client.
- What is a VPN and how does it relate to
MSUM-Wireless?
VPN stands for Virtual Private Network. Typically, a VPN
is used to establish a secure network tunnel between two
points through the use of strong encryption. Historically,
this technology has been used to securely connect employees
at home on the Internet with connections to corporate
or educational networks that would otherwise be blocked
by a firewall or would potentially compromise sensitive
data should the data be transmitted in an unencrypted
format.
Security standards for wireless networking are still
evolving with various vendors offering support for different
standards on Windows and handheld device platforms.
Some of these wireless security methods to date have
been subject to compromise. MSUM-Wireless uses
proven VPN technology to connect Wireless users and handheld
devices in a more secure and consistent manner.
- Does the VPN software cost anything?
The VPN client is provided at no charge for users.
- Does
the VPN software cost anything for handheld device users?
Handheld device users will need to purchase a VPN client
to connect to MSUM-Wireless. The Handheld device
VPN Client supported by MSUM is CISCO VPN 3000 Series
Client.
MSUM does not supply this client. Users will need to download
the client.
- What is an SSID?
SSID stands for Service Set Identity/Identifier. It is
a name that represents which wireless network a user is
attached to. This is also called the “Network Name”
by some vendors.
- What are 802.11b, 802.11a and 802.11g?
802.11a, 802.11b and 802.11g are standards in regard to
wireless communication that have been developed by the
IEEE (Institute of Electrical and Electronic Engineers).
The IEEE is an international organization that develops
standards for hundreds of electronic and electrical technologies.
The organization uses a series of numbers, like the Dewey
Decimal system in libraries, to differentiate between
the various technology families.
The 802 committee develops standards for local and
wide area networks (LANs and WANs). 802.11 is then further
divided. 802.11b, or Wi-Fi, is a standard for wireless
LANs operating in the 2.4 GHz spectrum with a maximum
shared bandwidth of 11 Mbps (megabits per second). 802.11a
is a different standard for wireless LANs operating
in the 5 GHz frequency range with a maximum data rate
of 54 Mbps. Another standard, 802.11g, is for WLANs
operating in the 2.4 GHz frequency but with a maximum
data rate of 54 Mbps. 802.11g uses the same technology
as 802.11b but the bandwidth (speed) has increased.
- Does wireless interfere with other devices?
Yes, any 2.4GHz device that is near the wireless access
point or wireless card can affect the performance and
may shut off your network connection. These devices are
usually microwave ovens in close range, cordless phones,
cameras and other 2.4GHz wireless devices. Unauthorized
access points can also interfere with the MSUM-Wireless
network.
