Get a response?
Ping 127.1.1.1 - response?
Check your Dreambox communications settings very carefully.
Compare to those in my wireless comms. guide for the DB if you're not sure.
Are you sure you're setting your PC's IP correctly?
start/control panel/network connections/ then select the network connection that's connected to the Dreambox, then right click, properties, highlight Internet Protocol, then propreties button. Select 'use the following IP address', set it to 192.168.0.1, set subnetmask to 255.255.255.0. Set default gateway to 192.168.0.1. Select 'use the following DNS server addresses' and enter 192.168.0.1 into the 'preferred DNS server' - leave the alternate server blank.
Save it and check it again - and using the ping routine.
Let us know.
