Hello. Has anyone tried the QoS of BEFSR41 v4? I plan on getting a router with a good QoS feature, and I heard that BEFSR41 v4 has one. Is it any good, & does it allow complete bandwith control for every user connected to the router? I'd like to limit the bandwidth of PC's using P2P on my network so there can be enough bandwidth for me to use. Thanks.
