What do you mean by "It stopped working"? Which part of the network adaptor is no longer working? The HDD part, the ethernet interface or the modem?
Could you also elaborate on what you experienced? If you do not tell us what exactly is wrong, we cannot offer you better advice.
From what I see, it really appears that some connector is damaged... but I don't know what that connector connects to.
