Ok, so the wi-fi router is 192.168.0.1 and the computer is 192.168.0.108.
Boot up takes about 1 minute 50 seconds in total starting with regular flashing blue for about 24 seconds then a solid red (orange?) for 6 seconds then more flashing blue until you get a steady blue.
The NASNavigator front page tells me all the Workgroup/IP Address/Subnet Mask/Default Gateway/MAC Address/Firmware details.
No error message is shown.
I can access the Web Settings screen.
McAfee firewall recognises when the dirve is on/off line.
Thanks in advance for you help on this - it is appreciated.
