My g/f has a laptop that, a month ago, was working on her lan (3 computers, router connects to internet).
However, after some messing about with network settings, the computer wont even recognise the router when plugged directly to it (standard lan cable).
I believe its because the computer is looking for a connection through the internet (its IP address is 169.... rather than 192.168.0.100, its previous working version).
Also, all the other computers on the network are working fine, and the cable is transmitting packets (in small amounts, probably connection checking packets?) so the problem must be with the laptops network connections.
Ive pulled up the Local Area Connection properties, and set TCP/IP properties "get IP/DNS address" to automatic (which works fine on other networked computers).
As it is, I have absolutely no idea whats going on. My previous experience with networking says it should just *work*, but evidently it isnt.
Thanks in advance
