When i use another dreambox in the place of this it works well.So router and cable are ok.
i know how to put ,and i put the ip manually but nothing to conncet by internet
check ur network settings, make sure ur box is the same network as your router(ie if router ip add 192.168.0.1 then ur box ip must be 192.168.0.x, x=2..254 and netmask 255.255.255.0, gatewate addr and nameserver = 192.168.0.1)
Try this and should work fine
IP - 192.168.0.x
Subnet - 255.255.255.0
Gateway - 192.168.0.1
nameserver 1 - 194.168.4.100
Nameserver 2 - 194.168.8.100
Some routers use 192.168.1.1 so amend your IP and Gateway to suite!
Eg -
IP - 192.168.1.x
Subnet - 255.255.255.0
Gateway - 192.168.1.1
Hope this helps!
