Current Wireless zones:
All residence halls
As of the fall of 2008, all residence halls are wireless.
Most of the Library is currently setup for wireless. However
there are a few "dead spots". Approximately 90% of the
carrels do have wireless access. For a graphical overview
of the areas covered, click on Wireless Coverage Maps below.

Wireless SSID (network name)
Currently in academic/administrative areas we are using:
(This SSID will be phased out in most places in 2012)
(This SSID will be phased out in 2012)
Uses WPA/PSK TKIP (WPA Personal)
Throughout campus we are using:
(This SSID will be phased out in 2012)
Uses WPA/PSK TKIP (WPA Personal)
This SSID is for campus visitors.
(Note: SSID entries are case sensitive)

Setting up your Wireless connection
We also have a guest user SSID: MHC Guest. This will allow for limited access to services.
|When selecting an Encryption method to use with a
wireless connection consider the following:
- Do not use basic WEP, it is insecure. Basic WEP Encryption has been proven to be "crackable". It will take a hacker only a few minutes to decode a WEP encrypted wireless session, and start to watch the wireless network traffic.
- If at all possible, do not use an open, unencrypted connection. If your connection is not encrypted, most of what your computer is transmitting (over the air) is in plain text. That means that someone with a wireless "sniffer" (a device to grab the data packets out of the air) can watch what you are doing. This becomes important when you are entering your username and password or bank account information on a wireless connection.
- Secure protocols, such as HTTPS for the web, IMAPs for email, ssh (putty), and sftp do
their own encryption before the data leave your computer. (Most banking and online
purchasing use HTTPS, as do the College web applications that involve logins, such as
Webmail/Webshell, ISIS, etc.)
- Consider using secure protocols on top of the built in
encryption, such as SSH and SSL. It doesn't hurt to be extra safe.
Registering Your Wireless
|You will need to register your wireless network card. This is done by connecting to an Access Point and attempting to connect to a web page outside of Mount Holyoke. You will be presented with a network registration web page to register your wireless network card.
Pros and cons of wireless
The major advantage to wireless is obvious. You can easily
take your laptop computer anywhere and maintain network
connection without having to find a wired data port.
This single advantage greatly outweighs the list of
disadvantages, but it is important to keep those disadvantages
in mind when using any wireless system.
A wireless connection is not as fast as a wired connection.
In most cases, this difference is not that important, but
if you are downloading large amounts of material, it is
better to have a wired connection.
Wireless signals can be degraded because of interference
from a number of sources of other radio waves. These
- Other access points not part of the system
- Microwave ovens
- 2.5 Gigahertz cordless phones (a very serious
source of interference)
- Absorption and Blockage
Some materials block wireless signals more than others.
Water can absorb the signal, so being surrounded by
people can cause some degradation of signal.
The signals may bounce off some materials like metal
used in plumbing, air ducts, bathroom fixtures,
and elevators. This can make for poor signal strength in
kitchen or bathroom areas.
- Number of users
Unlike a wired connection where you have a dedicated
connection to the network electronics, in wireless you
are sharing a connection to an access point with others.
More users on an access point can reduce performance.
The Aruba system in the dorms allows for a denser distribution
of access points so that the chance of overloading any
one access point can be minimized.
- Distance from an access point
As you get farther away from an access point, the signal
strength becomes less and the system throttles the speed
down so that data can get through on the lower strength signal.
A weak connection from one computer can actually affect other
Personal access points
We have not yet set any policies on personal access points.
Other institutions have banned individuals from bringing their
own personal access points
because they interfere with those provided by the institution. We have not taken this step... yet. You do not need to bring a wireless AP to your dorm because by the fall of 2008 all dorms will be 100% wireless.
In the meantime, however, if you have your own access point,
here are some guidelines to avoid problems:
- Set the channel to Channel 1.
- Do not use MHC as the SSID since you
would then be masquerading as College equipment.
- Set up encryption on your access point to prevent
others from using it.
This is especially important to avoid any risk
of lawsuit. If you allow another computer
to use your access point and if that other computer
engages in copyright violations by sharing music or
videos, it may be your connection that is
recorded as the copyright infringer and you will be
the one that organizations like the RIAA
or MPAA will go after.
- If you have a device that allows multiple wired computers
and if that device has wireless, turn off the wireless
and only use it for your wired connections.
- If you are using an Access Point that is also a home router, be careful how you connect it to the network. The port labeled WAN will connect to the data port in your room while the LAN connections are designed for internal (room) computers. Plugging it in backwards will cause your port to be shut off.
2.4 Gigahertz cordless phones
These phones can completely stop a wireless connection.
If you have such a phone, using it near your wireless laptop
is likely to stop your wireless connection completely.
Using this kind of phone is also likely to interfere with
your neighbors' wireless connections.
If you have such a phone, talk to your neighbors (including
the floors above and below you) to find out if your phone
is interfering with their network connections.
Consider a 900 MHz phone instead of 2.4 GHz one (a 900Mhz phone will not interfere with a wireless connection).
We will need to gain more experience with this to determine
if these kinds of cordless phones can be allowed in areas
with wireless network coverage.
Microwave ovens work on the same frequencies that some wireless networks run on. This can cause the wireless signal to vanish for the time period the Microwave oven is in use.
Students wanting to use the wireless network are required to run a
second ip-request to register their wireless cards.
