How to tune my router's advanced Wi-Fi settings?
Below is a list with recommendations for tuning Wireless router settings for best performance in normal small home/office network environments.
Airtime Fairness - disable, it causes connectivity issues with various wireless printers and other devices.
MU-MIMO (Multi-User MIMO) - It has some benefit to multicast traffic in Qualcomm routers only, better disabled for Broadcom routers. It only works with multiple clients that support it. It works for Qualcomm-based routers (QCA9984 chipset, Netgear 7800, Synology RT2600AC, Asus BRT AC828) and Qualcomm/Intel clients. For Broadcom based routers (as most other Asus routers, etc.) MU-MIMO support is not very mature and is likely to lead to worse performance.
Explicit Beamforming - disable, non-standard and may cause compatibility issues with some clients
Turbo QAM - disable - only helps with very few clients that support it.
Universal Beamforming - disable, non-standard, might cause compatibility issues with some clients
