I have a similar problem with connecting to servers. With my old computer and old ISP LFS ran perfectly.
Now i have updated both comp and ISP, and moved to a new apartment.
Im running LFS on a 2x2.4ghz intel with 4 gig ram and Geforce 9600M GT.
I have a 24mbit ADSL Line, so bandwidth is no broblem.
When trying to connect to a server i almost never get a connection. It fails at different points of the access to.
Did not recieve guest info.
Fails to load skins, 
Did not recieve OK from server.
When i finally get connected to a server it runs perfectly though. No lag och disconnections. Its only connecting to servers that almost always fails. 
And if a connection is successful the connection process is really slow... takes almost 2 min to get connected. 
When i run the tests i see i have major packet loss. I really miss LFS and need help to get it running.
