At the moment, i don't have much knowledge of the history of this problem but the symptoms are that neither wired ethernet nor wireless works* on this Asus X5DIJ laptop under Windows 7. Neither does it work under Ubuntu. Since there are no deactivations of networking possible in the bios (i don't think) and networking isn't disabled through function keys, i'm suspecting a hardware problem.
I wonder if that's a correct (very) general diagnosis or is there something else? If so, why would network hardware fail generally?
*'Not working' so far, means the following was noted
a. ui networking applets reported 'limited connectivity'
b. ipconfig shows an 'empty' tunneling entry
c. ifconfig (in Linux) reported having an ip address and i was able to ping other boxes on my lan, but not outside it (using an IP address)
