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)
