The Business School has one of the largest
wireless networks on the campus of the University of
Michigan which provides our student, faculty and

school and not be able to use
our wireless network with a
laptop, cell phone or PDA
because it requires a UM login?
With our new network,
unauthenticated guest access is
provided with very low speeds to
support email and web access.
Our new 802.11n wireless network supports a more unified and seamless network
environment by combining the mobility of wireless with the performance and
security of a traditional wired network. While our current 802.11a/b/g
network has served us well for over ten years, the new 802.11n network has many

Wireless Card with WPA support
We recommend an integrated card or the Orinoco 11Mbit Gold
card. B/G combo cards will also work. See
related section on this page.

Name to the Card Driver
You must enter our network name (SSID) in your card
driver. Our wireless SSID (ROSS WIRELESS) is now
broadcast to ensure connection to the correct campus

We support the Cisco Aironet
802.11 a/b/g Wireless Cardbus Adapter, which is a standard PC card that
fits into any PC Card Type II slot.
Other types of wireless cards may work on our
network, but are not officially supported and we cannot guarantee their
performance - your mileage will vary.
Your card must
be 802.11a/b/g standard with WPA security
Students can borrow a wireless card from the
Kresge Library Reserve Desk for a period of one day. Most students opt to
purchase their own for convenience.

Wireless is not a
perfect technology. The following will help you make the
best decisions about when, where and how you use
Are You Dropping Signal?
Some wireless chipsets need driver
updates. The predominant symptom is fluctuating signal
strength - one minute you'll get an excellent
connection, then the signal starts to fade and you're
unable to communicate. The signal strength may jump
back up and you may be able to reconnect, but it will
continue this connect-disconnect cycle indefinitely. If
this is what you're seeing, visit our
our Laptop Support Team or view the
Intel wireless chipset page for more details.
Some locations have a stronger signal than others.
There are areas around the school where signal strength
will be weak, for example, if you sit behind a
steel/concrete elevator shaft on the 4th floor of the
Speed? It's Who You Share With
Wireless uses a shared bandwidth. Our wireless network is properly configured on
each floor to handle "normal" types of activities (opening Word files, opening
web pages, etc.). Avoid bandwidth intensive activities such as
downloading large media files or playing bandwidth-intensive games when using
this shared resource - please use a wired Ethernet 100MB connection for these
Problems may result from other devices using the same radio frequency. The
Business School Wireless LAN uses the FCC unlicensed 2.4 GHz
Industrial/Scientific/Medical (ISM) band. Wireless transmissions within that
band conform to the IEEE 802.11 DSSS (Direct Sequence Spread Spectrum) wireless
LAN specification. Certain other "wireless" devices exist in the market place
that also employ the same 2.4 GHz frequency band and can cause interference to
users of the wireless LAN service. These devices include, but are not limited to
other IEEE 802.11 wireless LAN devices, cordless telephones, cameras, and audio
speakers. Computing Services requests that use of all other 2.4 GHz devices
be discontinued in university-owned buildings. Please work with our staff
for cases where the device is being used for a specific teaching or research
Still Think There is a Problem?
Most problems with accessing the wireless LAN are related to setup - 95% of
problems come from the client not being configured properly.
