Wifi stop working after few days

Hi,

 

I'm using a RockPi 4 B as a wifi access point. Everything is working fine with good performances until the Wifi stop working, usually after 3-4 days.

When that happens, dmesg is flooded with these logs :

[221057.075187] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110
[221057.075202] ieee80211 phy0: brcmf_cfg80211_get_station: GET STA INFO failed, -110

[221127.217806] ieee80211 phy0: brcmf_cfg80211_get_station: GET STA INFO failed, -110

 

Reloading `brcmfmac` module do not fix the issue, only a reboot.

 

I'm using the latest firmware provided by armbian-firmare :

I'm not sure where to go from there. How can I debug or workaround this issue ?

Have you contacted driver maintainer?

[NicolasA]

Hi,

 

Thanks for your answer.

No, who would that be ? The manufacturer or the kernel developer ?

 

According to some rasberrypi forum, this type of errors could come from the firmware.

I found a newer one (v 7.45.96.68) here : https://github.com/armbian/firmware/pull/19

I'll give it a try and keep you updated.

Hi guy's! anyone had experienced wifi desconections and very low wifi performance overall on mainline??

 

I have those on any of my rk3399s sadly. does anybody tried a workaround?? 

 

 

it's a really bad chip but on rpi4 it performs quite better (sadly).

I also not experienced this kind of performance on previous kernels.

I can only speak for the Pinebook Pro whiches WiFi runs stable for me on 5.10.y

[NicolasA]

The issue is still here with the firmware v 7.45.96.68. Wifi crashed a little bit before reaching 5 days uptime.

I will see if there is a way to reset the wifi chip, as a workaround. Unloading and reloading the module is not enough.

 

@Werner Which firmware are you using with you Pinebook ? ( You can check it with `dmesg | grep brcmfmac`)

[NicolasA]

So, I did test with multiple firmware revision : 7.45.96.0, 7.45.96.40-apsta, 7.45.96.53, 7.45.96.61, 7.45.96.68, 7.84.17.1

They all have the same behavior, except 7.45.96.0 and 7.45.96.40-apsta which crashes after only 1 day (instead of ~4 for the others); and 7.84.17.1 which create a very high CPU usage and is not usable.

 

I found a workaround to reset the Wifi chip without rebooting :

echo -n "fe310000.mmc" > /sys/bus/platform/drivers/dwmmc_rockchip/unbind
sleep 1
echo -n "fe310000.mmc" > /sys/bus/platform/drivers/dwmmc_rockchip/bind

 

It's working but not a real fix. It would be better to have a crash-free firmware.

[NicolasA]

The above workaround does not work every time, once or twice and then you need to reboot.

 

I got some debug logs from the driver, dmesg is flooded with this error :

Should we contact Raxda or Ampak for this issue ?

same Problem here, armbian 64 oa a Rock Pi 4B with an BCM4345/9 Chip...

somone got it to work?
