OpenWrt 21.02.0 r16279 R6220 Problem with 2.4 GHz Radio

Tue Sep 28 16:16:19 2021 daemon.notice netifd: radio0 (1899): Could not find PHY for device 'radio0' Tue Sep 28 16:16:19 2021 daemon.notice netifd: radio0 (2019): WARNING: Variable 'data' does not exist or is not an array/object Tue Sep 28 16:16:19 2021 daemon.notice netifd: radio0 (2019): Bug: PHY is undefined for device 'radio0'

In luci i have Wireless is not associated and in Radio 0 settings, Operation frequency field is empty, i can't choose anythink. I noticed when i change 5Ghz radio 1 channel to higher than 40 i have this same problem as radio 0.

(I want upload log file and screen shot file, but there is a bug from github, Therefore I cannot upload files) (github bug: POST https://github-production-upload-manifest-file-7fdce7.s3.amazonaws.com/ net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH )

I used megasync and shared this files

I got the following error too

and it looks like iw doesn't recognize 2.4 GHz radio interface at all

@robin92 I have the same issue, have you fix your issue ?

[robin92]

No, not really. I wanted to buy another router anyway and haven't got enough time to look deeper into the issue with this one.

Message ID: @.***>

[DragonBluep]

https://forum.openwrt.org/t/r6220-could-not-find-phy-for-device-radio0-mt76x2-issue-continues/116665/4 @ligthpower said add these pcie reset pin definition to mt7621_netgear_r6220.dts solve the problem.

&pcie {
        status = "okay";

        reset-gpios = <&gpio 19 GPIO_ACTIVE_LOW>,
                      <&gpio 8 GPIO_ACTIVE_LOW>;
};

[pierrepinon]

@DragonBluep I try solution and share my feedback. Thx

[pierrepinon]

I add PR with fix in openwrt repository (https://github.com/openwrt/openwrt/pull/10125)

        reset-gpios = <&gpio 19 GPIO_ACTIVE_LOW>,
                      <&gpio 8 GPIO_ACTIVE_LOW>;
};

I tried updated: $ cat target/linux/ramips/dts/mt7621_netgear_sercomm_ayx.dtsi

...
&pcie {
        status = "okay";
        reset-gpios = <&gpio 19 GPIO_ACTIVE_LOW>,
                      <&gpio 8 GPIO_ACTIVE_LOW>;
};
...

or put changes into target/linux/ramips/dts/mt7621_netgear_r6220.dts

then created the image:

But still no 2.4g wireless...

I noticed my imagebuilder is on 21.02.3. I'm tring 22.03.0-rc4 now.

[weiqi-chen]

I tried imagebuilder 22.03.0-rc4, still no good.

@WeiqiChenCN Please build source code directly, imagebuilder seems only pack the packages, it won't build dts again.

[weiqi-chen]

I compiled openwrt by source cdoe. And I noticed that wireless is missing from Network.

Is there some options I not enabled in menuconfig or kernel_menuconfig? Who could help me out :rofl: ?

[pierrepinon]

@WeiqiChenCN I post a message on openwrt PR, you are right, the fix doesn't works as expected

[pierrepinon]

I have a WAC104 and R6220 in my network. It's build on same architecture with same chipsets, the only differences that R6220 have WAN interface and USB port

I have no issue with WAC104 after many reboot or electric issue, the 2.4Ghz card is always up

So, I flash R6220 with WAC104 image, but the issue is always there 😓

@pierrepinon Do you konw which options/switch to enable wifi drivers or somethings?

[pierrepinon]

@weiqi-chen follow the build wiki

Don't forgot to download official build config to build system with same official build parameters : https://openwrt.org/docs/guide-developer/toolchain/use-buildsystem

Great day

[pierrepinon]

Right now I build new image with some fix pull from wac104 dts file

[weiqi-chen]

I used this steps to build my image

git clone https://git.openwrt.org/openwrt/openwrt.git src
cd src
git checkout --detach v22.03.0-rc4
#modify: target/linux/ramips/dts/mt7621_netgear_r6220.dts
./scripts/feeds update -a
./scripts/feeds install -a
wget https://downloads.openwrt.org/releases/22.03.0-rc4/targets/ramips/mt7621/config.buildinfo -O .config
make -j $(nproc) defconfig 
make -j $(nproc) menuconfig
make -j $(nproc) world

Still no wireless interfaces...

[weiqi-chen]

Updated:

make distclean
export all_proxy=socks5://rpi-ubuntu:1090
git checkout -- .
./scripts/feeds update -a
./scripts/feeds install -a

wget https://downloads.openwrt.org/releases/22.03.0-rc4/targets/ramips/mt7621/config.buildinfo -O .config

make -j $(nproc) defconfig

make -j $(nproc) download clean world

#flash firmware, then reboot, and reboot again.
#Now I can see wireless(radio0, 5G).

#patch ./target/linux/ramips/dts/mt7621_netgear_r6220.dts

make -j $(nproc) world

#flash firmware, then reboot, and reboot again.
#Still no wireless(radio1, 2.4G).

This patch is not work as expected.

[pierrepinon]

FYI, when the device is switch off and start after a few minutes, 2.4Ghz pcie card works

[weiqi-chen]

But After time of about between a half of a day and a day, the 2.4G wireless is down. And could not start up again.

I'm afraid that I need to switch off the router and wait minutes and turn it back on to make wifi work again...

[pierrepinon]

@weiqi-chen I doesn’t have the same issue. But can you try to flash your device with WAC104 firmware (with force) ?

[gj86]

FYI, when the device is switch off and start after a few minutes, 2.4Ghz pcie card works

This solution works randomly. Sometime it never work, regardless of number of minutes or number of reboots.

[weiqi-chen]

Yes. That is a sad story.

[pierrepinon]

I just tried the last snapshot and I do not reproduce the problem for the moment

[gj86]

I just tried the last snapshot and I do not reproduce the problem for the moment

Same for me. Even if the 2.4G not detected, next reboot (without any wait) fixes it.

Spoke too soon. It's same as before, not fixed.

[jacgl]

The same issue on one of mine R6220 after upgrading 19.07->22.03 (probably no matter which build). I have to restart several times until 2.4G radio is discovered. Apparently, the 7603 chip disappears on PCIe, It is not visible in dmesg when enumeration is done, thus firmware not loaded. mt7621-pci 1e140000.pcie: pcie2 no card, disable it (RST & CLK)

[pierrepinon]

@gj86 I have rebooted my device many times (for new settings or by electrical issues) and have no issues with radio 2.4GHZ

Do you have news issues or try new build ?

[kgrodrigues]

From stock, I tried 21.02.3 yesterday, with 5 or so reboots, powering off for up to 5 mins I could not get my 2.4Ghz radio to show up. I downgraded to 19.07.9 and its been working fine.

The issue is not fixed, tried with August 5 snapshot.

a fix was tested successfully

[Djfe]

@ABusuuu please close this issue, everything has been fixed :) (see link from last comment) Even a new change that was made necessary by switching to Kernel 5.15 (Snapshot) https://github.com/openwrt/openwrt/pull/12042
