Progress: found references to mediatek chips needing 5.12 kernel, with suggestion to install the xanmod kernel. Managed to do that:

# uname -r
6.1.37-x64v4-xanmod1

I now find wlan0 exists in 'ip address' but NetworkManager, show it with 'not managed'

Deleted the references to wlan0 in /etc/netwprk/interfaces and restarted NetworkManager and wifi has connected!

Thanks for all the help!!

synaptic search for mt7663 only pulls up firmware-misc-nonfree which I've installed, but that only provides firmware in /lib/firmware/mediatek.

Which package might contain the module?

Ahhh, modprobe mt7663 says module not found!

Sorry, I only use traditional ifupdown for my networking, and since you mentioned editing /etc/network/interfaces I thought you did the same.

By the looks of it the kernel recognizes the hardware. I would have thought the boot-up log would mention that hardware and which firmware gets loaded. At least there should be some mt7663* module loaded. You may check that with lsmod.

Surely someone that uses NetworkManager may have further ideas.

Further digging:
# nmcli connection show
NAME UUID TYPE DEVICE
Wired connection 1 ce8605fe-de1f-4ce6-97d9-3f6e4c51fbfc ethernet eth0
Wi-Fi connection 1 779db10d-3968-4372-aa75-fa2753fee9f9 wifi --

and

# nmcli radio wifi
enabled

I've got used to Ubuntu which never required any of this digging around, so I'm not familiar with the various commands.

The NetworkManager appears to have the details for my wifi, not sure how, /etc/NetworkManager/system-connections/Wi-Fi\ connection\ 1.nmconnection contains:
-------------------------------------------------------------

$ sudo rfkill
[sudo] password for bill:
ID TYPE DEVICE SOFT HARD
0 wlan acer-wireless unblocked unblocked

2 bluetooth hci0 unblocked unblocked

and
yes, NetworkManager claims to be running - the network icon on the panel just shows the wired connection.

Have you got a network manager running?

Re: [SOLVED] No wifi on Acer Aspire 3

dummy@example.com (ralph.ronnquist) — Sun, 02 Jul 2023 13:36:42 +0000

what's the output of

# rfkill

(install it if you don't have it)

Re: [SOLVED] No wifi on Acer Aspire 3

dummy@example.com (bill.p) — Sun, 02 Jul 2023 12:46:15 +0000

Yes, I did. Now no 'missing firmware' entries on syslog, apart from ones before the reboot.

You may need to reboot.

I guess for an mt7663 you'll need to install firmware-misc-nonfree, possibly from chimaera-backports/non-free, unless version 20210315-3 in chimaera/non-free is enough.

Typically kernel modules that need firmware will say so into dmesg and/or syslog.

Re: [SOLVED] No wifi on Acer Aspire 3

dummy@example.com (rolfie) — Sat, 01 Jul 2023 19:58:00 +0000

Look at the boot messages or check the syslog for the phrase "missing firmware".

BTW, here is a tutorial: https://tutorialforlinux.com/2021/06/15 … tallation/

That talks about firmware. You will need to enable non-free in Chimaera's sources.list.
