The pointgrey page is unfortunately not reachable anymore. I increased the receive buffer with the following two commands: sudo sysctl -w net.core.rmem_default=31457280 sudo sysctl -w net.core.rmem_max=33554432

If this does not help try also to set the MTU of the desired connection (eth0 or similar) to 9000: sudo ip link set dev eth0 mtu 9000

Hope this helps!
