I have a RVS4000 router with firmware 22.214.171.124. I tested today and in gateway operation mode I reach an excellent 500-600 mbps in WAN-to-LAN or LAN-to-WAN test.
Strange thing is that when I switch to router operation mode, I can't get more than 20 mbps in any direction , without changing anything else except operation mode.
I have tested also with firmware 1.2.11 , and same behavior occurs.
Have anybody any idea?
