How Do I Configure my Windows XP Laptop for Wireless Access?
The wireless network at Haas is part of UC Berkeley's wireless network, AirBears. To set up wireless
connectivity at Haas you will need your UCB Calnet ID, and a wireless card. This document was
designed to be used with Windows XP Professional. If you have an older operating system, some of the
settings described might look a little different or will be located somewhere else, but your AirBears
connection should still work. We will cover the following topics in this document:

NOTE: These instructions and support are primarily for registered Haas Students. If you are a faculty or staff
member and need further assistance, you will need to enter a helpdesk job at (http://helpdesk.haas.berkeley.edu) to
have your wireless card and AirBears connection configured.
Windows XP Professional
802.11b based Wireless Network Adapter . High Speed 802.11a and 802.11g are also
supported in certain areas at Haas. Please see Haas Wireless Coverage table above.
Your wireless adapter must have its driver properly installed prior to following the
instructions on this guide. Please refer to documentation provided with your adapter for
driver installation. We recommend downloading and installing the latest version of
drivers for your wireless adapter.
Valid CalNet Identification (this is your Student or employee ID number and a
passphrase).
CalNet Identification
If you are a student and you need to set your calnet ID for the first time please go to the
website: https://net-auth.berkeley.edu/cgi-bin/krbcpw .
You will need an initial token (password) to setup a permanent passphrase. Your token is
the TeleBears PIN assigned to you from the Office of the Registrar.
If you are a faculty or staff member, please see Diana Burks to obtain a token. You will
need this temporary token to change your Calnet passphrase at the following website:
https://net-auth.berkeley.edu/cgi-bin/krbreg. Diana is located in the Mail Room (S545).
If you are a visiting scholar, you were not given a SID, but you may obtain one by
visiting the University's User & Accounts Services located at 2195 Hearst Avenue,
Room 111 (open M-F 10am - 4pm), 510-642-7355
If you are a student and you have forgotten your pass phrase you must go in person to
the University's User & Accounts Services and present valid identification (your Student
ID) so that you can be issued a new pass phrase.
For more information on CalNet IDs please go to this website: http://calnet.berkeley.edu
Security
The AirBears network is not secure. Traffic going back and forth is not encrypted, so it can be
potentially tracked by a hacker. To better protect yourself make sure to follow the guidelines

How Do I Configure my Windows XP Laptop for Wireless Access? (continued)
outlined in this UC Berkeley iNews article published in February of 2005: Best Practices for
Secure use of Wireless Networks
(http://istpub.berkeley.edu:4201/bcc/Spring2005/wirelessbestpractices.html)
Some of the tips included in the article are also included in the configuration setup below.
Prior to connecting to the AirBears network, download and install the Symantec Client
Security (firewall and anti-virus) package from http://software.berkeley.edu . Or
download and install only the Norton Anti-Virus software from the same place. Update
the virus definitions at least once a week.
Either use the Symantec Firewall (mentioned above), or enable the firewall that comes
with Windows XP Service Pack 2
Keep Windows and Office up to date with Critical updates. You should also configure
your machine to download and install new windows xp updates as they become available.
Turn off file sharing, and turn off auto complete on your browser.
Never use an unknown wireless network.
For more help on securing your computer, check the document Security Precautions
(http://groups.haas.berkeley.edu/HCS/howdoi/Haas_Email/security/Security_Precautions.pdf)
and the rest of the Viruses and Computer Security section on How do I website
(http://groups.haas.berkeley.edu/hcs/howdoi.asp).
Step
Procedure
Illustrations
1
Connecting to AirBears
Note: Make sure that your Anti-virus software and
windows operating system are up to date prior to
connecting to the AirBears network.
In most cases you will be automatically
connected to the AirBears network if your
laptop is within range of an access point, and
your hardware is working correctly.
All you need to do is open a browser and you
will be directed to the Vernier Secure Logon
page.
Enter your calnet ID (Student or Employee
ID) and passphrase to authenticate.
Click Logon User.

You will be warned that you are not connecting
to a secure network. Click Yes to connect.
You will then be redirected to your home page if
you have one.
If you do not automatically see the Vernier
Login page, please see step 2.
2
What if you are not Automatically
Connected ?
If you are not automatically directed to the
Vernier Secure Log in page, it could be that
Your wireless connection is disabled
You may need to set up your browser
to automatically detect your LAN
settings.
Or you may need to reconnect to
AirBears
To Enable your Wireless Connection, please
do the following:
Make sure you wireless adapter is inserted into
your laptop, and/ or if you have an integrated
adapter enable your wireless connection by
going to Start > Settings > Network
Connections
Right click on the wireless connection and
select "View Available Wireless Networks"
AirBears should come up as being available.
Click Connect to connect.
Note: If you are using the software that came with
your wireless adapter to manage your wireless
connection (s), enable and connect to the AirBears
network through there. Most new management
programs will also detect the AirBears network
automatically. But you must choose between the
Windows Connection Manager and your Adapter's
Connection Manager. You cannot have both
running at the same time or there will be conflicts
between the two.

To Configure your Browser to automatically
detect settings:
Open you browser, then go Tools > Internet
Options > Connections > Lan Settings, and
click on the box
"Automatically detect settings".
Click Ok.
To Reconnect to Airbears do the Following:
Although the Airbears network is pretty stable,
sometimes users do loose connectivity. It could
also happen that when you are trying to
connect there aren't any IP addresses
available for lease. But this should actually not
be a problem at Haas any longer because our
service was recently improved and 260 more
IP addreses were added to our pool-- in
addition to the 220 we had originally.
In any case, when your machine looses
connectivity, you will see a yellow triangle
with a question mark in the middle if you look
at the Status of your wireless network
connection. Go to Start > Settings > Network
Connections, Right click and select Status.
If you also click on the Support Tab, you will
see the message "Limited or no
connectivity".
To fix this problem and reconnect, click on the
Repair button.
Your machine will be reconnected in a few
seconds.

Logging Off Airbears
AirBears IP address leases should only last
around 15 minutes, however, unless you
disconnect or reboot your laptop you will not
need to reauthenticate every time the lease
expires. But if you are NOT going to use your
laptop for more than an hour, it might be a
better idea to log off the network --to protect
your computer.
To log off AirBears type 1.1.1.1 in your
browser's address bar.
Press Enter.
You will be directed to the Vernier Log In/Off
page.
On the upper left hand side you will see the link
"Logged on as: Your Calnet ID number".
Click the Logoff button on the right to log off.
