Hi Friends

I've installed Debian 11 LXQT in my hard drive.

I noticed connman does not automatically run on startup, which is fine.

I manually open Connman. It can detect my usb wifi adapter because under Wireless tab, it says

Wifi technologies: 1 Found, 1 powered

However under the same tab, all these buttons after greyed out:

Connect, Disconnect, Remove, Rescan

And I cannot see my router on the list below these buttons.

Tried connecting and disconnecting the usb wifi adapter, no change.

Tried using a pricier usb wifi adapter, same thing.

Tried plugging in a different usb port, same thing.

I had very little trouble connecting to wifi on Debian 10 xfce.

Should i just install Debian 11 xfce or is there a solution to this?

64-bit Debian, by the way.

Also, have the same issue on the live usb Debian 11 - cannot connect to wifi.

Bit off topic, Debian live usb comes with complete libreoffice except Base. The installed version on my hard drive has only libreoffice Draw, i think. Is this normal?

Thank you for your time.

are you using the nonfree firmware ISO?

Maybe you should use it because that's where you will find a lot of non free firmwares.

Check your kernel logs ($> sudo dmesg) , you may find an explicit reason why your adapter fails to run properly.

That wouldn't be fine for me.

I was under the impression, unless you've bought something,
that you were using:

Device-1: Broadcom Limited BCM4313 802.11bgn Wireless Network Adapter
vendor: Wistron NeWeb driver: bcma-pci-bridge v: N/A port: 2000
bus ID: 03:00.0 chip ID: 14e4:4727

which would require firmware. There's a wiki page:

https://wiki.debian.org/brcm80211

Most laptops' wifi will require firmware.

Cheers,
David.

I've downloaded this

debian-live-11.1.0-amd64-lxqt+nonfree.iso

Are there no sha512sum for the non-free version? All I can find in Debian website is this:

https://cdimage.debian.org/debian-cd/current-live/amd64/bt-hybrid/SHA512SUMS

which is the "free" version, correct?

Thank you

David

It would add useful information to the conversation if you
specify the URL (from where you downloaded it).
If you don't tell, we dont know.

To find the SHA512SUMS, did you try looking in the
same directory from where you downloaded the iso file?

For example, the URL directory:
https://cdimage.debian.org/images/unofficial/non-free/images-including-firmware/11.1.0-live+nonfree/amd64/iso-hybrid/
contains many files, including:
debian-live-11.1.0-amd64-lxqt+nonfree.iso
SHA512SUMS
