I installed the software and the adapter - very easy and it worked. However, when I went to switch off my PC, the old classic menu came up instead of the XP pictures for shut down / restart.
I switched off then when I rebooted my PC the accounts had gone and I could only log into the last account I was in.
Seems the software installs an rtlgina2.dll file, which messes up XP.
Netgear know about this problem but won't fix it.
On one PC I just uninstalled the software and removed their device. Unfortunately on the other I deleted the rtlgina2.dll file and couldn't get back into XP. I'm now having to spend hours reinstalling XP and all the programs.
I definately won't recommend this.
