Trying to get laptop to realise its on a lan/router

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.

Any ideas?

Thanks in advance

Other note:

When i say "wont recognise the router", when i ping it i get request timed outs. Other computers can ping fine.

Also, the Mac Addresses are both different, so i wouldnt think that would affect it.

try pinging the router.....
If there is a ping then try to manually set the IP of you laptop, while setting the default getway IP witj your router IP.
Ok, i uninstalled and reinstalled the drivers. It seemed like a strange thing to do, but it worked and now everyone is happy.

Thank you kindly liddler, youve saved me another 40 hours of grievance.
