I realize this looks a lot like a problem with the wired network. The POE is run through a 10/100/1000Mbps 4 port + 1 uplink Gigabit IEEE 802.3af PoE switch and ASUS RT-66U wireless router. Powering the POE switch (and thus the cameras) does not improve the frame rates. Rebooting the router doesn't fix the problem either.
The problem likely is not due to buffers:

I would like to know if anyone else has seen a similar problem or has any ideas on how to chase this down.
Thanks,
