Diagnose Wi-Fi performance issues
This advertised speed is a theoretical maximum; under perfect lab conditions. Real world speed is different as you can see in that article I linked to earlier. What you're trying to do now is optimize as many settings as you can to get as close to the maximum as possible. Can you repost the new 5GHz WiFi Analyzer screenshot with the new setting changes? Also, share the screenshot of the WiFi settings on your R6700 (i.e. advanced settings). Please obfuscate any passwords or identifying information. That isn't surprising given your 2.4GHz output. But you should be able to use 5GHz without much issue.
The new analyzer is set up with your router configuration. I believe this matches your expectations. All QoS features are turned off, except WMM, which is active on both 2.4 and 5GHz bands.
You're only managing about 200mbps during speed tests, which seems like a limitation. I'm settling for that result and moving forward. I believe I've covered all troubleshooting steps. If frustration builds up, I might contact Netgear regarding their refund policy. Could there be a reason your WiFi drops completely once the upload starts? When I previously checked speeds, they were fast until upload time, after which everything stopped working.
I’ll point you back to the article I mentioned before. Real-world tests show 200Mbps on 5GHz is what you typically see with the R6400. In ideal lab conditions it could work better, but home setups aren’t like that! The speeds claimed by wireless router makers are usually only for perfect environments, which can be misleading. Still, they can’t predict all the obstacles or interference a regular user might encounter. If your router supported MU-MIMO and wider channels (like 40MHz, 80MHz or even 160MHz), you might get a bit more speed on the default firmware, but you’d still need compatible devices with adapters that match. What rates do you achieve if connected via Ethernet? Assuming no other apps are using bandwidth, you should reach your full 600Mbps download speed, as LAN-to-WAN throughput usually hits around 700-800Mbps in actual use. Ultimately, if you’re happy with these speeds on WiFi and can connect many devices over Ethernet, a 600Mbps connection makes good use of your investment. You can try third-party firmware (such as DD-WRT or Tomato/forks) to check if performance improves on the R6400, but note that hardware acceleration is generally only available in the original firmware. On the other hand, if you rely solely on WiFi, it might be time to consider an upgrade.
