Wifi not working in Lenovo laptop/Ideapad/Atheros QCA9377

[senthil kosapeta]

Dear Debians,

I have purchased Lenovo laptop around 6 months back. (Lenovo ideapad)
I had installed ubuntu earlier and Wifi used to work fine.
Somehow it got crashed a month back.

I have decided to switch over to debian 9.9 and installed it.
Internet via Ethernet port is working. But wifi is not working and not
showing available wireless networks.
I searched/googled certain topic related to Debian wifi and tried
installing firmware-atheros earlier.
It did not work. When i tried restart, shutdown is stuck.
If i force shutdown and restart, It will be stuck again.
When i tried to do recover mode, msg displays that
"ath10k_pci ** failed recieve control reponse completion, polling "

Please let me know how to proceed.

 Thanks
Senthil

Hi，

Can you see your wireless interface by excuting /sbin/ifconfig -a

should have device wlan0 or wlo0 or wls0p0 listed there

if not，you missed driver for that device，either look non-free repository or
download source code compile yourself

Hi, can you check for firmware loading information in your logs ?

"grep firmware /var/log/messages" or "journalctl -b" and look for info 
related to the wifi chip.


Given the "shutdown stuck" issue I would try disabling interrupts and 
see if it solves the problem, "modinfo" says ath10k_pci accepts three 
irq options:


"parm:   irq_mode:0: auto, 1: legacy, 2: msi"

Maybe try "legacy" mode first, that may be what Ubuntu is doing as a 
default. You will need elevated privileges to run the next commands 
("sudo command" or "su -" and then type commands).


First two commands unload the driver module:


modprobe -r ath10k_pci
modprobe -r ath10k_core

Then reload it with proper option:

modprobe -v ath10k_core
modprobe -v ath10k_pci irq_mode=1

If it solves the problem you can make the change permanent.

Hope it helps.

The error message is very generic (ignore the message regarding the 
graphic chip, it's unrelated and mostly harmless).


First look into the firmware directory to make sure you do have the 
needed firmware binary:


ls -l /lib/firmware/ath10k/QCA9377/hw1.0/

You should see a "firmware-6.bin" file in the output.

Then try the commands I suggested before in a terminal window, you need 
to do this as root, either by using "sudo" in front of the commands or 
by doing "su -" and ater providing the root password type the actual 
commands one line at a time:


modprobe -r ath10k_pci
modprobe -r ath10k_core

modprobe -v ath10k_core
modprobe -v ath10k_pci irq_mode=1

and report back to the list the outcome.

Hi,

Earlier my system got stuck after firmware-atheros installation.
Now i have freshly installed debian 9.9.

So it does not have following
/lib/firmware/ath10k/QCA9377/hw1.0/

Shall i retry installing "firmware-atheros" and proceed as per your
suggestion?

Hi, most people on this list prefer bottom-posting rather than

   I looked into the firmware-atheros package in Debian Stable (9),
backports, testing and unstable. Only the version in unstable currently
has the firmware file you need to make your wifi chip work
(/lib/firmware/ath10k/QCA9377/hw1.0/firmware-6.bin) .

You can download it yourself on one of the Debian mirrors:

https://packages.debian.org/sid/all/firmware-atheros/download

Then install the package with the command:

dpkg -i firmware-atheros_20190502-1_all.deb

This command must be issued in the directory where you downloaded the
package, and with root privileges.

When this is done, simply reboot your system, or unload/reload the
driver module with:

modprobe -r ath10k_pci
modprobe -r ath10k_core

modprobe -v ath10k_core
modprobe -v ath10k


Ignore the "irq=" option for now, I am on Debian unstable and wrongly
assumed you had the needed firmware file already on your system.



HI,

My system got crashed.
After installing firmware-atheros, I tried modprobe commands. (Even before
restarting)
When i am done with last command which is "modprobe -v ath10k_pci", system
got stuck.
I had force shutdown, and restarting the laptop is hit with the same old
problem like earlier crash.

When i run through recovery mode, it says following (also seen during
earlier crash)
*ath10_pci *** : failed to recieve control response completion, polling ...*

After that i tried booting via debian live usb, got the root prompt, tried
following commands

modprobe -r ath10k_pci
modprobe -r ath10k_core

modprobe -v ath10k_core
modprobe -v ath10k_pci irq_mode=1


It is still not working and is stuck while boot.
Please suggest more.

Sen




Hi, which version of the firmware-atheros package did you install ? Was 
the installation successful, no error messages ?


When the boot sequence gets stuck, when exactly does it happen, what do 
you see on the screen ? If you crashed the system a few times, the 
file-system may need to be checked, did you see any message mentioning 
"fsck" or file-system check ?


Nota: you can answer back to the list only, I am subscribed.

Snipping and quoting: Re: Wifi not working in Lenovo laptop/Ideapad/Atheros QCA9377

Thanks for the consideration!

I think another part of it for most of us (I take myself as a sample of one 
representing most of us ;-) ...

.. is that we like quotes of previous emails to be snipped to the relevant 
part and then the response to that relevant part be underneath that quote.

If you are replying to more than one relevant part, snip  irrelevant parts, 
and intersperse your comments within the email, under the relevant part.

If anyone wants to chime in and agree (or disagree), please do!

Hi there, I mostly agree but I also have to say that I don't really give 
a damn about netiquette as a whole as long as the problem is solved, and 
it is still possible with minimum efforts to make head or tail from the 
thread. Now this thread is already mangled beyond recognition twice, 
sent all over the place and back, from several different addresses, and 
I don't have time to fix it today.
I also feel the need to say that meta-discussions about style or 
off-topic and/or personal matters on this list is seriously putting me 
off lately. I personally feel much more problematic to scroll through 
several unrelated messages scratching personal itches much more painful 
that any formatting bias.
Maybe it would be better to send a polite message to the original 
"offending" party(ies) once (off-list?), and if they don't comply just 
stop helping at all if one feels strongly about it.


Taking my own advice, I won't argue on the subject of style anymore in 
this thread ;-) .
