Troubleshooting / FAQ
Use this section to locate answers to frequently asked questions.
What should I do if I already have a version of Client Manager on my PC?
Update your Client Manager to the version on the CD. If you do not update
your Client Manager, there could be a loss of functionally, as some versions of
Client Manager will not work properly with the G54 Wireless 54Mbps Desktop
PCI Adapter. Before updating Client Manager, you must uninstall all previous
versions of Client Manager. To update your Client Manager, load the Air
Navigator CD and select Install Client Manager.
Why won't all my network clients work?
Some operating systems support only a limited number of network clients.
Windows 98/Me: These operating systems support only four network clients. If
you install more than four network clients, only the first four clients you install
will work.
Will Client Manager support all operating systems?
