Has anyone tried VoIP for this router adjusting the QOS? It appears the WPC4400N card is meant for tablets and laptops. Does anyone know if it comes with the PCI adapter and antena for desktops? I use multiple remote admin softwares in simutaneous sessions to servers around the US and a VoIP phone to our office. I am getting lockups due to the QOS or lack of real QOS on Netgear WNR854T. It is like all traffic chokes for 20-40 seconds and I can reconnect. I'm looking for a good router with QOS, wireless and gigabit.
