Configuring UVM Wireless on Windows XP
For best results, ETS recommends that you upgrade your computer to Windows 7
or later before using the UVM Wireless Network. If you must use XP, the installation of XP Service Pack 3 is required before
connecting to the UVM Wireless network. To determine your current Service
Pack level and install Service Pack 3 if necessary, see
Installing Service Pack 3 in this document. UVM Wireless will work with
XP Service Pack 2, but several hotfixes or third-party software components
will be required for reliable connectivity to the network.
Many systems will have third-party wireless card management software
installed (such as "Intel ProSet Wireless" or "Dell WLAN Configuration
Utility"). ETS strongly recommends disabling or uninstalling this
software. Information on
ProSet can be found in the
XP Configuration with
Intel ProSet section of the UVM Wireless documentation pages. The
remainder of this documentation assumes that you have disabled third-party
wireless management tools.
Installing XP Service Pack 3
Microsoft has added many enhancements to XP's wireless capabilities since the
release of the Operating System in 2002. To ensure maximum compatibility

A Note On Password Caching:
When you provide your username and password to the XP Wireless Connection
Manager, this information will be cached in the Windows registry for future
use by the currently logged in account. This behavior cannot be
disabled. If users of a shared computer log into the same local
account, they will end up sharing this wireless password cache as well.
Thus, if you are sharing a local account on a Windows XP machine, you likely
will not want to connect to the UVM Wireless network.
If this situation cannot be avoided, it is possible to delete the
Wireless password cache. It is recommended that you configure shared
systems to run the following registry update on each logout or reboot:
(The utility "reg.exe", which is included with Windows XP Professional, can
be used with the "/import" switch to automate this registry update.)
