I have the same issue with regards to my download and upload speeds being in the ~900mbps range when directly connected to my modem, but ~350mbps (down/up) when connected to my RAX80.

 

I was not able to enable and then disable QoS as it hangs on 'Attempting to connect to Netgear Server. Please Wait...' followed by 'No new database version available.'

 

I did have a *little* success following one of the other above steps. I followed the instructionsd on determing the optimal MTU settings (in my case that number came out to be 1300). This had no noticeable effect. I changed it to 1472 as someone above had mentioned and my download speed went from ~350mbps to ~450mbps and my upload went from ~350mbps to ~900mbps. So from 350/350 to 450/900. 

 

Another interesting thing I noticed was that when I was testing the speed through the RAX80's QoS Setup menu it varied significantly from my speedtest.net speeds after the last MTU change. Before making the last MTU change, it was relatively close to the values I was seeing through speedtest.net. After the change it now shows my down/up as ~800/400

Speedtest.net ->  450/900

QoS Menu -> 800/400
