M1's official image (Ubuntu 20.04 - 20220926) pended about 100 seconds when no network interface is connected.

Hello all,

I bought two boards, the 1st is N2+ and the 2nd is M1.

N2+'s official Ubuntu image (22.04 LTS + install ubuntu-desktop) works as usual. But M1's officlal Ubuntu image (20.04 LTS) has a trouble for me.

1. With Ethernet (wired) connection : no trouble, works great.
2. Without Ethernet connection / Plugged in WiFi dongle 5BK : delay after this message around 100 seconds.

I guess this might be caused network related things, but Ubuntu OS for N2+ doesn't have this trouble.

How can I fix (or change settings) for this? (w/o network connection)

Thank you

Did you try after disabling the interface (wired network) in Setting if you have Ubuntu Desktop?

I count't found wired configuration in the settings. (but wired Ethernet "eth0" is connected)


I resolve this issue using this steps.

1. Install "Ubuntu 22.04" using netboot installer in the Petitboot.
2. Install RTL8821CU driver ("sudo apt install rtl8821cu-dkms linux-firmware") (unless, 5BK's wifi didn't recognized)
3. Reboot

Thank you.
