Lately I've been SEVERELY lagging in Halo. I've never lagged like this before and I really have no idea why my ISP would be this bad. I use a Netgear router and connect through Westell which is branched with Century Tel. I've thought it could be my NAT but I don't really know much about opening my NAT and I really don't know how to go into my router through the computer considering I didn't install it and I haven't any installation discs for it.
