Since kernel kernel 4.15 (?) the wireless-regdb will be loaded from the kernel, i.e no need for crda anymore:
Debian does not include the new binary format of the wireless-regdb, yet.
See bug-report:
Debian Bug report logs - #892229 wireless-regdb: Missing support for kernel direct loading

Workaround: get latest regulatory.db
wireless-regdb regulatory database
e.g. from here: wireless-regdb/wireless-regdb-2018.05.31.tar.xz
wireless-regdb-2018.05.31.tar.sign

Download, verify the pgp/gnupg-signature, untar and
copy
regulatory.db
and
regulatory.db.p7s
to /lib/firmware

Or simply ignore the error message, if no wifi-channel regulation is needed for your country,
e.g. the global (US) channel regulation is good enough for you.

Thanks to Mike for bringing up this long standing annoyance.
Thanks to Fehlix for providing the workaround.

I've been ignoring those two for quite a while.
Nice to be able to eliminate them.
They even appeared before Plymouth started.
Especially objectionable on 32 bit where they lingered.

thanks fehlix for the workaround to clear those errors.

I did update the flash and upgraded to the latest firmware stevo just sent up and still no good.

Off to other busted stuff now.

i thought i was the only one with no working wifi on my dell inspiron laptop. I only tried mxlinux with live usb so far but since even in the live usb wifi is not working, I postpone on installing it on the laptop. The network assistant seems to be able to see wifi but nothing happen when I created and set hotspot wifi.

(Experience in the past I had with debian pure live usb not working wifi but ignored and installed on laptop only to also ended up with no working wifi especially to create hotspot.)

Mike,

Check out, on the right side, for a mechanical switch. It will turn on/off the wifi. Most Dell laptops have this switch (not obvious).

Thanks Siles but it's on. If I flip it to it's other position I can't see any networks.
And thanks to both of you too, I couldn't work out why I had no wifi networks displayed on my Dell machine either! I wonder if there's a similar keyboard command for a Compaq Presario tower as I haven't got a Compaq keyboard for it?

And no, I can make sure that it is not a switch problem on my laptop since my current os Linux Mint 18 wifi and its hotspot works just fine.
I even tried disabling by blacklisting one by one the network driver assistant list from ath9k, b43, b44, wl, mii, r8169 ... but nothing changed... I even upgraded those driver to see any changes but none worked.
Although I'm surprised by the fact that live usb created from mxlinux iso allowed update & upgrade of its application in live session. I can even save the session so does that mean what I did by upgrading those driver will be saved in the live session too?
Oh and I already update/upgrade the bios too and everything is OK at least there is no error display at all. All display OK in green when booting into live session.

Yup, my old latitude suffers the same symptoms. The wifi adapter can see wireless networks in it's vicinity (so hw wise, it's working) but it can't get authenticated to the one in my home.
I have other old & new hw that can get authenticated to the same access point so it's something with that laptop.

I have a (probably) different problem with a new Dell laptop (G3 3779). I tried running the MX Linux Usb Live installer, but it doesn't seem to recognize the wifi device at all. There are no listed wifi networks. It's working on an older laptop where I have MX Linux installed.

Code: Select all

inxi -M
displays machine infos, but

Code: Select all

inxi -v 2
(with wifi info) gets stuck. Wireless device shown by windows is

Code: Select all

Intel(R) Wireless-AC 9461
Any idea on how to solve this? Thanks

Probably wl is not the correct driver. Did you tried brcmsmac?

Sometimes it's better to buy a 10 euro usb network stick instead of waist hours of debugging.
I had a lot of problems on Broadcom chips on my old laptops and waist a lot of time ...
Most problems was the firmware was missing or the bandwith was like modem!
