Optimized build for IPQ40xx devices

nephilim · August 12, 2023, 10:29am

Did you install the FW compiled by @sshel ? Did you flash it directly over Linksys stock FW? I am asking because for the (similar?) MR8300 and official OpenWRT the installation has to be done in two steps (22.03 > 23.05), otherwise the device will be soft-bricked.

I posted 22.03.5 It is installed as the original software. You can flash it then change fw_setenv kernsize 500000 and then flash 23.05.0-rc2, 22.03 05 performance is better but it does not support DSA and vlan

Does anybody have a good working download for the mr8300?

Hi.
That is not exactly as it is to be understood (I wrote the doc BTW). You need a preliminary setting (boot variable change) to be done with a previous OpenWrt.
Once the change is done, you can boot everything : 21.02, 22.03, 23.05 and Linksys. So you can even reverse to Linksys, and flash directly 23.05 from it.

Hi! The file I used (kindly uploaded by sshel a couple of posts above) is "openwrt-23.05.0-rc2-ipq40xx-generic-linksys_mr9000-squashfs-factory.bin".

Yes, that's the firmware I installed, and yes, I flashed it directly from the Linksys stock firmware. The latest firmware wasn't giving me the option of updating, so I had to do it from 192.168.1.1/fwupdate.html

FYI. DSA Support is in OpenWRT 23.x. Which will hopefully be officially released soon (at the time of writing it's in RC2 status).

I built the latest firmware from notengobattery. The repository has been changed to the official openwrt You can test it https://sshel.inf.ua/mr9000/

Can someone point me to irqbalance script for IPQ40xx?

This is the script from NoTengoBattery, I use a modified version of it. Note that it's works in 22.03, but not in 23.05 as some interrupt names were changed. Should be easy to fix though.

Thanks, I startd to use 23.05 image and works really well. Thanks for your efforts.

Hi @Monnionni
Can you please share with us some experience about the wifi on 23.05? I would be interested in the maximum available speed and stability on WiFi.
Thank you!

Monnionni · November 7, 2023, 7:42pm

Hi, I think Wifi is smooth and stable. I have connection 400/50 and added screenshot from speed test. My router is not optimal location.

gemolnar79 · November 7, 2023, 8:12pm

Thanks @Monnionni,
This is a similar result to that I can get on EA8300 with NoTengoBattery firmware.
Have you fine-tuned any wifi/system parameters to reach this speed or just using the default settings?

Monnionni · November 9, 2023, 4:24am

Hi, I just adjust channels. Maybe in the upcoming weekend have more time to look into it little bit better.

Monnionni · November 18, 2023, 3:07pm

It shows there is already 23.05.2 ready to download. Fast paced, thanks

guys, does anyone has any advice how to improve I have EA6550v3 using OpenWrt 23.5.02 and while is apparently working fine, I've found that that the 2.4 Ghz signal is very weak and 5 Ghz is more or less but I really like this hardware but it doesn't work fine like the custom builld from NotengoBattery.

I've been testing for a few weeks with the 23.5.x while is nice I think we don't get a good performance. Anyone has any idea how to improve or advice in channels? or region settings?

I could return to NotengoBattery's custom mod for older openwr but his site is shutdown and I dont find any other place where to get it. I would love to maybe setup or adapt his customizations to the 23.5.x

also does anyone had improvement with irqbalance script for IPQ40xx?

Will it work for the linksys mr6350???
