[Solved] Can't get wifi to Work on pi5

[Rabie]

I think that wifi.tcz doesn't really work well.

When I install the Raspberry Pi OS, the Wi-Fi works great!

I tried copying the necessary drivers from Raspberry Pi OS, but then the Wi-Fi chip goes into panic:

Hi Rabie

... When I install the extension normally and delete my copied driver files

Code: [Select]

tce-load -wi wireless-KERNEL.tcz firmware-rpi-wifi.tcz wireless_tools.tcz wpa_supplicant.tcz wifi.tcz
wireless-6.12.25-piCore-v8 is already installed!
firmware-rpi-wifi is already installed!
wireless_tools is already installed!
wpa_supplicant is already installed!
wifi is already installed! ...

You should not need to load all those extensions individually.
So, I have to ask, did you do a proper install of  wifi.tcz  and its dependencies?
The dependency tree of wifi.tcz looks like this:

Code: [Select]

wifi.tcz
   wireless_tools.tcz
      wireless-6.12.15-piCore-v8.tcz
         regdb.tcz
   wpa_supplicant.tcz
      libnl.tcz
      openssl.tcz
         ca-certificates.tcz
      readline.tcz
         ncurses.tczThose extensions would get loaded automatically when wifi.tcz gets
loaded, but only if wifi.tcz was properly installed

[Rabie]

Hi Rich, yes i tried to delete all extensions and just install Wifi.tcz alone it installed the dependencies automatically.

Doesn’t matter what i do i get the errors with the brcm

I bought another pi5 hardware and i will try to set it up on Wednesday to see if i got the old one broken.

Should wifi.tcz be in onboot.lst alone or should the dependencies also?

Hi Juanito,

I assume that I broke the wifi chip with the following command:

Code: [Select]

iwconfig wlan0 power off 
Please don’t ask me why I tried the command   

I even installed pi os and ubuntu to try the wifi and it doesn’t work there too

[patrikg]

On the pi5 it has onboard flash-able bios.
Why not try to install the latest RasberryPIOS and update the eeprom/bootloader

[Rich]

Hi Rabie

... Should wifi.tcz be in onboot.lst alone or should the dependencies also?

Alone. It takes care of the dependencies.

... I assume that I broke the wifi chip with the following command:

Code: [Select]

iwconfig wlan0 power off  ...

Did you try reversing that with:

Code: [Select]

iwconfig wlan0 power on

[Rabie]

Hi Rich,

Did you try reversing that with:
iwconfig wlan0 power on

yes i tried but after powered off the interface wlan0 doesn’t appear any more to power it on
Anyway i get an error if i try that

[Rabie]

Hi Patrikg, I think this is a good idea, i will try it on Wednesday

On the pi5 it has onboard flash-able bios.
Why not try to install the latest RasberryPIOS and update the eeprom/bootloader
https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#rpi-eeprom-update

[patrikg]

And always with these pi's they need a good PS(Power Supply), is that the raspberry pi one for the pi5 ?
