Hi,
I haven't seen that error before, but it seems to be advising that it can't see the SpeedTouch device.
How does your computer connect to/with it...?
On my old ST routers, it connected with a USB cable.
My current setup means that the router connects (via network cable) to my firewall/switch, and all of my computers connect up from that... Or at least the first ones do, I have had to extend my network out to cover all areas of my home, including three Wireless Access Points...
