Any router can be used on any platform, they are platform agnostic. All the CD does is help you configure the router, but most home routers have web interfaces for doing this. In the case of the Netgear router, this can be accessed through:
http://192.168.0.1
I believe the default username and password is:
user: admin
password: admin
She'll want to:
- change default router password
- change network name (SSID) optionally
- choose a security technique - either a MAC access list or WPA/WEP password (otherwise the network is wide open and anybody can access it)
You may or may not want to upgrade the Netgear's firmware to the latest version to accommodate a security technique of choice depending on how old the router is. However, I had lots of problems with newer versions of the firmware on my old Netgear router I used to use.
If all of this security stuff is a little out of your reach and if you think that locking down the network is important for her, let us know and perhaps we can simplify what I have written.
