Notebook IP address 192.168.0.9/255.255.255.0. It has an onboard realtek RTL-8139 network module, the hardware control centre correctly identifies it and lists the 8139too module (driver?).
I can ping localhost and ping the IP address on the notebook OK. I can't ping further than that, nor can I ping the notebook from another
Not good. Try pinging the broadcast address from the notebook.
machine (when the notebook is booted under linux). I don't know what to do now, and don't want to give up! Can anyone help me?
Then tell us what your routing table looks like (route -e).
You also might want to check dmesg and tell us what 8139too spits out when it loads.
Next, make sure that there is no firewall absorbing all the ICMP requests (external pings).
