RAX40 - I just started using it - tips for better performance?

I'm using my cable-modem (C6250) to connect to Comcast and I have over 200Mbps for download and ~12Mbps for upload. I'm also running some tests with the AC3200 (R8000) to see the differences with the performances.

 

The C6250 is a cable modem/router. The R8000, like the RAX40, is a router. So you have two routers on your network.

Two routers on your network can cause headaches. For example, you can end up with local address problems. Among other things, the other router can misdirect addresses that the Netgear router usually handles, such as routerlogin.net or the usual IP address for a router, 192.168.1.1.

Unless you have specific reasons for using two routers – to create two separate networks for example – it is often easier to use just one router and then to set up the second router as a wifi access point. Netgear advises this, as does just about every site you will visit.

It is possible to put the modem/router into modem only (bridge) mode and then to use the second device as the router.

There is a manual for the C6250 somewhere at the end of this link:

See the section Cable the Modem Router to a Router and Use Bridge Mode.

I have the QoS turned on..

 

Why? Unless you have a problem that you are trying to fix, QoS can just slow down the network as the router dedicated its power to managing connections. At 200 Mbps, you are on the edge of the speeds where people advise that QoS is a waste of effort.
