Thread: Connecting disconnects me from my network?

So I have a bit of a problem with people logging in, and I have absolutely no idea what could cause this so I have finally turned to where I highly doubt I will get any useful response, here.

Anyways...

So the first person to try to log into my server connects, then I drop all network access. I cannot access the internet or for that matter my router. If I disconnect manually from the network and reconnect, as long as I keep the server open, any connections following that initial connection work fine and I no longer get disconnected. Any ideas?
