Does this indicate a problem with my router or is it due to misconfiguration? The test is performed over LAN and with an Ethernet cable between the router and the PC.
Edit: Using a BT HomeHub 5A, with no other client connected to the router.

It's not recommended to use the openwrt router as either iperf client or server.
Please repet the test with 2 PC class systems - one on the wan side and the other on lan.
