What port on the SB8200 are you connected to? 

Make sure its port 1 and nothing else is in port 2. 

have you tried a different cable between modem/router? 

After you reset the RAX15, did you ever speedtest it with it running in default configuration? without changing anything in settings? 

I'd try this.

    • Port 1 on the SB8200
    • Swapped cables
    • Speedtest after factory reset 

    Same result

    I usually don't say this (and not sure if rax15 has this) but have you went into the dynamic qos and manually set your speed?
