100mbps connection should mean that you are on a company that has made a local internet connection and you have speed of approx 100mbps to all the people in this LAN. But outside I hardly doubt you will have such connection.

Also if your LFS is loading textures too slow(too slow PC or too high res textures or both lol) then your LFS might just lose connection until it loads them. And ask your isp where you have 100mbps connection to. I find it hard to believe that home network packet can have a speed of 100mbps but what do I know, I live in a poor country.

100mbps is pretty common where I live (and that is in an area just north of stockholm, sweden). But I still get this problem sometimes and I think that is because my SSD is not good at writing stuff... :-(
When connecting to the server I get a lot of skins (as I guess you do) that has to be written to the HD (SSD). But if I try again it usually works.
So, do you have a SSD or a regular HD?
