Problem with tekkit lite multiplayer server

[mcdonaids]

Hello, I've recently started playing tekkit lite with a few of my friends and I get this end of stream error whenever I try to play on my wifi in my dorms at my college. When i'm at home, I can play tekkit lite just fine, it seems the issue lies within the dorm. Like, I would spawn inside the floor and would not die and the tree-capitator mod takes several minutes to load, sometimes it doesn't load at all and I crash with the end of stream error. I just have hug lag to the point where whenever I break a block, I don't get it as a pick up. I've looked around on the internet and I can't seem to find anyone whose had a similar issue but has found a resolution. Any help is appreciated
