"Shaping" of incoming traffic would only (if anything) have an effect on applications that received that traffic and/or CPU usage, it wouldn't change whether or not packets got to you. The problem is that by the time the packet is in the shaping routine, it has already inherently passed your network interface. At that point, it had already passed your ISP's router and any limitations they have on your incoming traffic (like speed caps, etc.). If your interface was fully congested or your incoming bandwidth is saturated at the ISP link, the ISP would be dropping/queuing packets, not you. If you are experiencing incoming network congestion (packets are out of order during high usage times is a good indicator), then ask your ISP if they will shape the traffic to you based on your preferences. -- Michael T.
