I have a D-link DI-524 wireless router and D-link DWL-G520 adapter card.
All the firmware and drivers and all that gobblety-goop are updated on both.
The startup disc came with additional software called Network Magic for managing and securing the
network, but it was too much trouble to fool with as it would absolutely not recognize the adapter
card. So I just uninstalled it.
The network operates just fine without the additional software, but is not secure.
The directions for securing the network without Network Magic are extremely vague.
So, if anyone can help me out, I'd love you forever and be your best friend!!!
