I had this REALLY annoying too. It started occuring after I did a format. I replaced my modem for a different reason with the same issue.

Doing the above worked. Setup the modem to use a 'Pure Bridge' rather than 'PPPoE and create an internet connection from within windows.

Who knows why it worked before and not now. Hopefully the developers find a solution.

Quote from Bogey Jammer :

Good new

I managed to connect to any LFS server.
I applied the same internet connection method with my new modem as my old one. It seems to like it because it automatically switched to bridge mode . I still hate this modem..
I remember that I had lowID problem with eMule several years ago with my old modem. That's why I switched it to bridge mode. It's probably the same problem with LFS.

Here is my workaround; sorry for French XP screenshots (and possible wrong translation to english):

1. Open network connections in windows configuration panel
   
2. Then click on "create a new connection" on the left
   
   
3. Click "next" and select "establish a new connection to internet"
   
   
4. Select "Manually setup my connection"
   
   
5. Select "Connect to a (wide band) using an username and a password"
   
   
6. Enter a name for your connection
   
   
7. Enter the username and password your ISP gave to you. NEVER tell them to ANYONE!!
   
   
8. Click finish
   
9. Before using this connection make sure your modem is disconnected from internet (not from your computer!) and set it up to make it in bridge mode (depending on the model, maybe it's automatic, I don't know)
   
10. you can connect to internet with your new connection method
    

Hope this will help the most users as possible.. For me the problem is solved.

Thanks heaps your name will be put on my numberplate

Am looking at getting a full set of red bull skins for each car in LFS.

Has anyone get a XRR red bull skin or might be able to quickly whip one up? Have looked through the first 45 pages of the finished skin XR thread with no luck. Search came out empty.

I am too n00b at photoshop to even attempt it and paint ones look ugly.

Thanks
