I'm on a college network. My Xbox is connected to the internet via ethernet cable. It keeps saying I don't have sufficient MTU settings, but I checked, and our settings are currently at 1500. I've connected to LIVE before on this network, last time I had to give my MAC address to the ISP so he could let it go through. I've already done that, and the Xbox is still saying there's not enough MTU.
Any suggestions or any other problems there might be? Thanks.
