Generic Optimal Router Settings Guide
1. 802.11 n Support
Enable: Faster speed by supporting N or later wifi tech.
Disable: Older devices cannot connect.
2. WMM Settings
Enable: Many mobile devices like iphone and ipad need it to function.
3. 2.4 Ghz vs 5 Ghz
2.4 Ghz: 802.11 b/g. Slower and more interference in most cases.
5 Ghz: 802.11 n or above. Faster and less interference when setup correctly.
4. 20 Mhz or 40 Mhz (And Best Wireless Channel)
20 Mhz: Use for 2.4 Ghz wireless frequency.
40 Mhz: Use for 5 Ghz wireless frequency.
For best channels for each of the wifi frequency, refer to the post itself.
5. AP Isolate
Enable: Public Wifi
Disable: Home Wifi
6. IP Flood Detection
Enable: When computers are infected with malware that overload your wifi network.
Disable: Usual Setting.
7. Multicast Rate
Enable: Used for public broadcasting or multicast for display use.
Disable: Usual Setting and lower rate.
8. Preamble Type
Short: Faster setting.
Long: Slower setting, better in high noise environment. Older devices supported.
9. Beacon Interval
Lower Value: 100 or Below. Default setting by most of manufactures. Work in most situations. Needed for time critical notifications like VoIP or push notification.
Higher Value: More free bandwidth and airtime means better performance. May take longer for router automatic SSID discovery.
10. DTIM Interval (Period)
Lower Value: 3 or Below. Default setting by most of manufactures. Work in most situations. Needed for time critical notifications like VoIP or push notification.
Higher Value: More free bandwidth and airtime means better performance. Weaker routers may crash and buffered data may be lost.
11. Tx Burst (Frame Burst / Pack Burst)
Enable: If less than 3~4 devices may improve performance. More devices can cause higher lag.
Disable: No bursting.
12. WMM APSD
Enable: Usual setting.
Disable: Only if your mobile devices have issues with crashes or disconnect.
13. No Ack / Ack Suppression
Enable: Only with good signal strength. Improve speed. May cause issues with data accuracy.
Disable: Usual setting for better compatibility.
14. Optimize AMPDU Aggregation
Enable: High error environment or multiple devices. Slower performance.
Disable: Low error environment with less devices. Faster performance.
15. Airtime Fairness
Enable: When the device that you wish to boost is the faster speed link. Or if you want to improve performance of network as a whole.
Disable: When the device that you wish to boost is the slower speed link.
Enable Explicit Beamforming: AC devices and few N devices. Mid Coverage.
Disable Explicit Beamforming: B/G and non-compatible N devices. Small Coverage.
Enable Implicit Beamforming: When Explicit Beamforming does not apply.
Disable Implicit Beamforming: Problems or small coverage.
17. IGMP Snooping
Enable: For Streaming and Airplay Mirroring
Disable: Default Setting for less resource overhead.
18. Jumbo Frame
Enable: For faster access to and from storage devices on a network. The implementation requires all devices on network to support jumbo frame.
Disable: You should generally disable jumbo frame for all other purposes.
19. NAT Acceleration
This option can also be CTF or FA in some other routers.
Enable: For internet provider speed above 100 mb/sec. Typically can improve performance with internet speed above 200 mb/s.
Disable: Disable to allow QoS, Port Forward, IP Traffic Monitoring, Parental Control.
