Could be that the router is using a link speed of 10 Mbps, or slowing
everything down with flow-control packets.
Several solutions are possible, depending on the switch:
- Try enabling IGMP support if available (so that only those ports
interested in the transmission do get the traffic)
- Try disabling flow control (some switches support this on a per-port
basis... If that is the case, you only need to disable flow control on
the port to which that router is connected)
