I am having problems connecting to the wireless network in the flat I am renting and will try to explain myself as good as I can, hoping that someone out there can help me out!

English is not my first language and I apologize in advance for any mistakes I may make trying to make myself understood!

I live in a rented flat where the wireless network is provided by my landlord. I do not have physical access to the router. I own 2 laptops and one desktop and all 3 computers have up until yesterday been connected to the network without problems. yesterday however, my desktop was suddenly disconnected. I have not made any hardware changes, nor any software changes lately that could account for the sudden loss of connection. None of my laptops were disconnected and both are still working fine.

At first I could not even find the network while scanning on the desktop. I tried to reinstall the card and drivers, and after some trouble I could find the network and connect to it. But after I found the network and connected to it the process stopped while "aquiring network address." After a while the status changes to "limited or no connectivity." in this mode I cannot access the internet.

I have noticed that the ip-address assigned to the desktop is very different from the one assigned to my laptops:

desktop: IP Address:

laptops: IP Address:

I have also tried to copy the laptop ip and assign it as static ip on my desktop. (also copying Subnet Mask, Default gateway and DNS server (while having no clue what these do)) When I tried this the status changes to "connected" but I still have no access to the internet (tried web browsers, msn etc)

As I mentioned earlier I do not have access to the router, nor do I know what brand/model it is. I probably could get access if I asked my landlord, but I haven't bothered since I have no clue what I should try with it.

The wireless card I have in my desktop is a CNET CWP-854. I might also add that I use the Railink Wireless Utility to configure the connection.

I hope someone can understand more of this problem than me, and that you are kind enough to help me out!

thanks in advance!
