Please publish the complete WiFi source code kernel

Why is the 5G WiFi signal of the ROM built with your source code is particularly weak and the signal of Oxygen OS 5G WiFi is particularly strong Please publish the complete or specially optimized WiFi code

I guess problem is not just kernel or WiFi kernel modules.
I've tried to use custom ROM with Oxygen kernel and Oxygen WiFi modules and still had same weak signal.
More likely needd changes are in system (wifi-service, wificond). WiFi firmware may expect some commands from system to configure its transmition power.

If OnePlus reads this, leave comment to confirm my guess.

Yes, there may be many other things that they haven’t released. I heard that this problem affects the entire 7 series models’ third-party firmware. WiFi 7pro, 7t, and 7tpro have similar problems.

Because this changes not a part of Open source you can forget about it to be released.
You must find solution by yourself.
Some time ago i've tried to fix 5GHz band power, but no luck. Then i just dropped my attempts.
I'm for 99% sure that wifi-service.jar controlling WiFi power and with help of vendorcmdtool sending commands to WiFi driver.

Wow! If successful, the 5GWiFi problem will be resolved, then you will make a major share for the 7T custom community

And I found that not only the 5G WiFi signal is weak, the 2.4G WiFi is also a bit weak

No change whatsoever in 5ghz wlan performance. Also it appears to load same firmware with or without this change on HD1905 for me.

Seems it hanged at some point, will attempt to get a better log.

it loads proper FW now.

You should now see that 2.4GHz TX power is increased ( 20 -> 23, check iw reg get )

Will do, apologies for the false alarm. I tested range with my drone, and as usual it was poor on 5ghz compared to my other device and my old OOS test.

Really nice work if this helps some people.
