Same Wifi MacAdresses on 2 Devices
cyclemat opened this issue · 10 comments
today i have flash a seconf pad but the problem is now the twodevices have the same mac adress so the DHCP trys to give booth the same ip adress and cant handle two pads at the same time. has anybody two pads and confirm this ?
MAcadress on my pads is fc : ee : 92 : 11 : 14 : 05
I only have just 1 pad but I can confirm that this is the exact same MAC address mine is using.
It can be 'reconfigured' somewhere in the "/etc" folder.
have test macchanger but didnt work !
I'm currently too lazy to dig more into it but this, while it's for orange pi, looks promising: https://dietpi.com/forum/t/orange-pi-zero-wlan-mac-address/929
have test to change the macadress via macchanger
sudo systemctl stop moonraker.service
sudo systemctl stop KlipperScreen.service
sudo ip link set dev wlan0 down
sudo ip link set dev eth0 down
sudo macchanger -r wlan0
sudo macchanger -r etho
sudo ip link set dev wlan0 up
sudo ip link set dev eth0 up
sudo systemctl start moonraker.service
sudo systemctl start KlipperScreen.service
on eth0 it works but on the wlan0
wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
link/ether 5e:25:53:fe:da:08 brd ff:ff:ff:ff:ff:ff
Maybe this:
`
cat /etc/modprobe.d/xradio_wlan.conf
options xradio_wlan macaddr=DC:44:6D:D3:A6:7F
`
Check existence of that file and content. If it not exists, create it. Reboot.
nope didnt work
I'm nowhere near my pad. So I can't try out some things myself.
But tomorrow I will.
have found this https://dietpi.com/forum/t/orange-pi-zero-change-mac-wifi/1028/2
MAC must be changed in file /etc/udev/rules.d/70-persistent-net.rules
MAC must be changed in /etc/modprobe.d/xradio_wlan.conf
but he didnt write what must in 70-persistent-net.rules
For me it's working as expected
sonic@sonicpad:~$ ip a

sonic@sonicpad:~$ sudo grep -iR "fc:ee:91:00:29:ee" /etc/
/etc/wifi/xr_wifi.conf:FC:EE:91:00:29:EE

grep: /etc/sv/ssh/log/supervise: No such file or directory

Then I was simply running:
sonic@sonicpad:~$ echo "FC:EE:91:00:29:EF" | sudo tee /etc/wifi/xr_wifi.conf
sonic@sonicpad:~$ sudo reboot
And when the Sonic Pad was available again:
sonic@sonicpad:~$ ip a
4: p2p0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether fc:ee:91:00:29:f0 brd ff:ff:ff:ff:ff:ff

BUT, I admit my system was already modified and I can't remember what all I did. One thing though which comes into my mind is:
sonic@sonicpad:~$ cat /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
#fsck -p /dev/mmcblk0p5
#mount -o remount, rw /
echo "mmc0" > /sys/class/leds/sys-led/trigger # Blink blue led when mmc0 is accessed
cat /sys/devices/platform/soc/usbc0/usb_host # Enable CAM port as usb host
/usr/bin/brightness -v 25 # Reduce brightness a bit
exit 0
sonic@sonicpad:~$ echo "FC:EE:91:00:29:EF" | sudo tee /etc/wifi/xr_wifi.conf sonic@sonicpad:~$ sudo reboot
Works best was we create a first run script that starts and create the xr_wifi.conf with a randome mac adress.
