Wifi connection problem

Hello

I can’t connect to wifi.

I connect first with ethernet,
do dietpi-config and enable wifi,
so wifi is connected at this point,
but when i restart i have no wifi, and no ethernet !

what am i doing wrong ?

to have ethernet again, i need to unplug the wifi dongle, even with wifi off.

My setup :
Odroid C1+
dietpi 5.15.93
wifi dongle with MT7610U

Does it show up under
lsusb
?

If not already available, try this
Linux support for MT7610U based products - ALFA Network Docs

Also…first thing to do always on ethernet (or a connected wifi) is to do an (as root or sudoer)
# apt update && apt upgrade -y
To ensure all drivers and kernel’s are updated to latest

i made a new install, update+upgrade,

I made :

sudo cp -p /lib/firmware/mt7610u.bin /lib/firmware/mediatek/

to put the firmware in the right folder

and i made the wifi working at first boot with dietpi-config

here is the result :

sudo dmesg | grep mt

BUT when i reboot, there is no wifi and no ethernet,
i need to unplug the wifi dongle and reboot to have the ethernet back

Can someone help me please ?

Thanks
Thomas

the wifi works if i start without the wifi dongle
and if i plug it after the boot…

it is strange

OK !
I found a solution :
i had mt76x0u in /etc/modules
and it works
