If the Buffalo is configured with a fixed IP address, you need to have the
laptop within the same subnet (IP address has to start with the same
numbers, but has to differ in the last (at least) number).
Unfortunately you didn't tell us, which IP address the box has, which IP
address the laptop has nor which address range the router is providing
to its clients. In addition to this, you didn't tell us, if the router is serving
as a DHCP server (that is the machine, providing clients with dynamic IP
addresses, if they are not configured with fixed IPs) at all.
If the IP addresses are from the range 192.168.x.x, or 172.16-32.x.x, or
10.x.x.x, this means "private network" aka. no access FROM internet is
possible. Every other range (except 164.254.x.x) is "public network" aka.
access FROM internet.
Summary: you gave not enough information to us for valuable help.
DO NOT USE the NASNavigator for ANYTHING regarding the box.
You can make it worse with this "dummy" tool.
Thank you for your reply. I will try to answer. I pretty much feel like a 'dummy' tool at the moment.
The laptop pulls its IP from the wireless internet router, 192.168.1.* (showing Yes by DHCP)
The Linksys router appears as MAC Bridge Miniport 192.168.0.* (showing No by DHCP)
The Buffalo drive has an IP of 172.50.50.*
At one point the, Broadcom adapter showed a matching IP of 220.127.116.11 (although I still could not access the drive); now it appears in IP config as the Miniport, pulling its IP in the 192.168 range.
I was able to install a new Buffalo device (trying to see what happens when one is installed for clues) directly to the laptop, using a crossover cable between the new Buffalo device and the laptop. It mapped itself to L: drive by name, no IP. So I assumed that the fixed IP of the drive might be the issue, but I have no idea how to resolve that disparity.
I'll not use the NASNavigator, got it!
Again, thank you for your reply, and I hope the information that I have provided is more valuable for finding a solution. I appreciate your patience.
