Raspberry Pi Forums

Hi,

I am a total newbie when it comes to raspberry pi, linux, and all of this stuff. I found an old raspberry pi (1 b+) which has no wifi-module and i am now trying to install a wifi-dongle on it.

But, low and behold, i am greeted with errors which i cant seem to find an answer to, not specific and/or intuitive enough anyways.

What i have done:
Downloaded the drivers
Managed to run the install.sh

What happens:
make[1]: *** /lib/modules/4.9.59+/build: No such file or directory. Stop.
Makefile:1551: recipe for target 'modules' failed
make: *** [modules] Error 2
####
Compile make driver error: 2
Please check error Mesg
####

Would be lovely to get some help with this, cant really make anything out of it...
And you would need any more information from my part, just holla.

regards
Contigo

Try a 'sudo apt-get install raspberrypi-kernel-headers' first.

hi, thanks for the reply.
I have installed the kernel headers, but still recieves the same error message.

also, i am trying to run rtl8821AU, not rtl7721.

I have a generic rtl8812 based Wifi adapter bought on eBay, I tried building the drivers on Jessie and gave up so I'm having a go on Stretch. But for really old Pi's I'd buy a known compatible version, I have an Edimax based on the 7811 - works perfectly and you'll never need the 802.11ac speed....

I'm rebuilding the drivers right now, having installed the headers as suggested above, but I am following this post https://www.erol.name/compile-realtek-r ... -jessie/

Start at the point where it says 'If you are going to compile on Raspberry Pi', after doing these steps from the top of the same post...

sudo apt install git
git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux
cd rtl8812AU_8821AU_linux

sudo make clean from those instructions doesn't work until the headers have been installed...
then sudo make - this might take a long time.... it does on a Raspberry Pi Zero

Make sure wpa_supplicant.conf is set up properly and reboot.

The generic adapter seems to be connected and working, try iwconfig
