I have a RVS4000 router with the V22.214.171.124 firmware. Static IP's on the WAN with default settings. The issue is we are getting strange upload/download speeds and our ISP says that out WAN connection should be set to Full Duplex. But their isn't an option to change it and it reports itself at half duplex. I can't find a way to change it. Let me know what I can do or if anyone has any questions. Thanks!
