Any chance to get some update on this optimized build? The stable version of the 21.02.0 out there. Maybe there are some advantages of the new version.

Axl_Mas · October 22, 2021, 11:48am

I moved to official 21.02, it is working well in everyday use (working from home during the day, torrenting during the night). I didn't test WPA3.

An optimized build upstremed would be more than welcome
Let's wait for @Bartvz 's feedback

Enig123 · October 31, 2021, 6:09am

@Bartvz, do you have any trouble trying to get a working build from the latest master codes?

I am asking because I've got serious trouble with master snapshot builds, recent builds made the WiFi chip just disappeared. Not sure about the latest latest, since I have to revert to 21.02.1 release for usability.

diizzy · November 20, 2021, 6:37pm

Works fine for me using 5.4 kernel

Regarding performance I'm seeing around 300mbit in WDS mode (WPA3) with a few simple optmization patches applied to source. That seems to be the limit for the SoC...

Bartvz · December 22, 2021, 4:01pm

Christmas came sort of early, r18381 is here.
My server literally exploded (PSU) and that took a while to get around to. Also my work has kept me extremely busy so no free time to tinker with stuff

! Before flashing !
This has not been tested on real hardware so only flash if you are able to restore the router to a working state.
Also, since there are lots of changes please do not keep your current configuration when upgrading. Start from scratch.

What's new?

Upstream changes, most notably Linux kernel 5.10 and the latest mt76 driver
Compiled with GCC 11 and binutils 2.37

Axl_Mas · December 23, 2021, 10:43am

Thank you Bart!!! Merry Christmas openwrters

Bartvz · January 3, 2022, 12:50pm

So, I had finally time to flash it and so far (12h) it seems stable. What are your experiences?

Axl_Mas · January 12, 2022, 7:40am

Hello, I confirm that r18381 is working very well! I reactivated also the 2.4g wireless (I disabled it some time ago) for connecting an old device, it is as well fast and stable.

JuggernauT · January 22, 2022, 12:17am

After flashing r18381, mine says:
OpenWrt SNAPSHOT r16249-9ac47ee469 / LuCI Master git-21.077.59320-d1bf56d

That does not seem like a match?

JuggernauT · January 22, 2022, 1:50am

second flash and it appears as it should.

frite · January 23, 2022, 5:53pm

Working nice
Thank you

xabolcs · February 12, 2022, 1:33pm

Looks like the Possible Kernel 5.10 regression issue with MT7621 and SW/HW offload enabled problem going to be resolved soon.

It already works with DHCP. PPPoE also works, but it needs a manual step to drop down sirq to 0%!

zsw · March 15, 2023, 4:03pm

Hello, currently I'm using the openwrt-22.03.3-ramips-mt7621-dlink_dir-860l-b1-squashfs-sysupgrade.bin. I get drop connections and the overall signal strength is poor.
Is there a better bin that I should test with?

Bartvz · March 15, 2023, 5:23pm

I would try the snapshot releases and upgrade with attended sysupgrade whenever there is a new version of the mt76 driver.
This build had been discontinued.

zsw · March 15, 2023, 5:50pm

Thanks for the direction. Switching from 5Ghz to 2.4Ghz has made a major difference. Out of curiosity, how do I know which version of the mt76 driver I am currently using?

Bartvz · March 15, 2023, 6:40pm

You can see the version by looking at the hashes and compare those to the source: https://github.com/openwrt/mt76

After forking of a stable release, the driver tends not to be updated.
