1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

LAN settings, make sure NOTHING there is checked.
3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link).
