Improve Performance and Reliability

After smashing my head against the wall wondering why Airlink and virtual desktop couldn't seem to manage more than 70 Mbps but would dip wildly and stutter; Here is the guide to fix this god damn router for better device to device performance ect. Useful for sending large files, VR Desktop, Remote play, steam link, Steam VR, Meta or Oculus Quest 2 air link, and just using your devices.

 

 1. Separate 2.4Ghz from 5Ghz (Give them unique names and passwords IE. Duma2.4 Duma_5Ghz)

2. Turn off Congestion Control, useful for exclusive use of online multiplayer gaming but if downloading files or using a local network it WILL throttle performance. 

3. Disable all Traffic Prioritization, most devices and apps can do this auto-magically you do NOT want packets getting held, for best performance send a packet as soon as it is ready, you want a lower ping, correct? Then why add latency to each packet that is so dumb.  

4. Enable AX, Enable OFDMA in 2.4GHz, Enable OFDMA in 5GHz (if router supports wifi 6, this will use wifi 6 protocol AX and will separate channels into smaller "chunks" increasing speed while reducing noise) 

5. In Advanced settings > Wireless settings > Enable Beamforming, enable MU-MIMO, enable AX again. (I have no idea why these are not on be default... even $50 routers manage to auto enable MU-MIMO and beamforming)

6. Reboot router then Enjoy a router that works properly! 

Testing now has Quest air link locked at 200 Mbps (max speed at time of testing) sending a steam game from PC to gaming laptop via local connection shows stable 1,100 Mbps (max speed of gig ethernet port)

MU Mimo is only useful for clients that support it and you need at least 2 and to be within a fairly close proximity.

2.4Ghz is used mainly by IoT and these devices are normally WiFi 4 and so OFDMA has no effect on them. Some tend to isolate their IoT due to security as they are often left behind by security updates once they reach point of end of support while some get none. Latency will be higher and throughput will be slower. Add into it the streams and client wait time.

I believe you are at max or round about for the Quest wireless connection. 
 

love my Quest 2, not bad tech for the price.

99.9% of Households have a small to medium sized space (close proximity) and have over 10 MUMIMO devices as the tech is old. ((even my Panasonic plasma supported MUMIMO))

Any device that supports wifi 6, 5, 4, ect will support the 2.4GHz band; it's not a generation, is a FQ spectrum range so, again most users will have low priority devices set to the 2.4GHz band such as smartphones, smart lights, smart TVs, microwave ovens ect. So that isn't an issue the reason to ensure separation is to keep the 5GHz FQ range clear and open for high priority devices. IE a quest 2 or gaming device.

Yes, with the instructions this will keep quest 2 at 200 Mbps stable and allow for low latency multiplayer gaming with it via steam == quest link. 

Something that the DUMA router out of the box was unable to achieve even with the router celling mounted, 15 feet away from the quest 2 from it, the pc and router all in the same room within 15 - 20 feet of each other. 

 

 I made this to be helpful to many users. I am not sure what the point of your post was.... Do you want to compare computer science degrees, because I'll pass.
