Help fix 40 MHz in the tp-link tl-WR740N router. The router does not want to give out Wi-Fi in 40MHz. Are there any commands to fix 40MHz ....
In the native official firmware the router is able to distribute Wi-Fi on 40 MHz

Ensure you have set the high throughput mode on your wireless configuration (HT40+ or HT40-, depending on your base channel frequency): https://wiki.openwrt.org/doc/uci/wirele … vices_only

Then either ensure that there are no other Wi-Fi stations in your area, or use the 'noscan' option in your wireless config to override the high throughput fallback mode. The fallback mode will make your router use only 20 MHz channels when there's a lot of traffic on the 2.4 GHz band, in order to prevent the radio band from becoming congested.

The discussion might have continued from here.
