No wireless card detected...
« on: March 10, 2015, 09:15:06 pm »
Hi,

This is really awful. I'm running Peppermint with kernel version 3.2.0-65 on an Acer Aspire One. I've been very happy with this system for a couple of years now. Recently, i started a routine system update and because of a dodgy wifi connection, the upgrade failed. Things seemed to be working ok except i had no sound nor wifi. I re-started the upgrade from a couple of other wifi hotspots and finally via ethernet and was able to get my sound back. Still, my wireless isn't working. "iwconfig" gives "   lo        no wireless extensions" and "eth0      no wireless extensions." indicating that the modules/drivers for my adaptor are not installed.

Now here's the funny part - when i boot into Mint 14 or Peppermint 5 from a USB stick, everything works perfectly!

The obvious easy solution is for me to do a re-install from my USB. I really don't want to do that because i have two years of tweaks here that i'm not in a position to restore. It would take too much time. I mean, my system is very, very customized. I'm practically the only person who can use it ;-) So, what i'm looking for is a quick and dirty way to install my wireless adaptor. Simple step by step instructions. I find it hard to imagine that during all of these updates that the proper software didn't get installed. I know there isn't anything wrong with the hardware because it's working under Mint and Peppermint from USB. Help!

Thanks.

What happens if you run:
Code: [Select]
sudo modprobe ath9k
if wireless springs to life, we'll have to add that driver to /etc/modules so it's loaded at bootup

if wireless doesn't spring to life, post the output from:
Code: [Select]
lspci -vnn | grep -i net
and
Code: [Select]
lsmod

I know that sounded a little confusing. Yes, it is Pep5 on the USB stick. On my machine, it's Pep4. I noticed something else, Synaptic Package Manager seg faults. Won't run at all any more. If anyone else were having these problems, i'd just tell them to back up their "~/" and reinstall. The problem is that this is my main production machine and i'm just not in a position to take the necessary down time to rebuild it. I have so many apps and scripts installed all over the place. I don't even remember half of the stuff i've done. I just know that i have an environment that works perfectly for what i do day to day - except for the wifi ;-)

Thanks,

Jair-Rohm

Yup, it looks like we may have found the problem. Here's the output from "modprobe ath9k":

FATAL: Error inserting ath9k (/lib/modules/3.2.0-65-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k.ko): Unknown symbol in module, or unknown parameter (see dmesg)

What shall i do now?

Thanks,

Well Pep 4 is dead, no longer supported... If you plan on building a machine like that which does all your daily stuff, you would be better off with pep5 it's an LTS release, and good for 4 more years...   Just saying I wouldn't trust a dead horse with my data...    :)

Peppermint 4 shouldn't have the 3.2 kernel, it should have the 3.8 kernel .. are you sure we're not talking about Peppermint 3 here.

You're also confusing me by saying you ran an update, but now you're saying update segfaults  :-\

Can you post the output from:
Code: [Select]
cat /etc/lsb-release
and
Code: [Select]
uname -a
and
Code: [Select]
dpkg -l | grep linux-image

Be Aware - The above commands MUST be run from the broken OS, not from a LiveCD session

Hi,

Thanks a million for your help! Yes, i was wrong, i am running Pep3 as the output from these commands will show:

cat /etc/lsb-release
DISTRIB_ID=Peppermint
DISTRIB_RELEASE=3
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Peppermint Three"

uname -a
Linux jairrohm-AO756 3.2.0-65-generic #99-Ubuntu SMP Fri Jul 4 21:04:27 UTC 2014 i686 i686 i386 GNU/Linux

dpkg -l | grep linux-image
ii  linux-image-3.2.0-23-generic           3.2.0-23.36                                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
ii  linux-image-3.2.0-39-generic           3.2.0-39.62                                         Linux kernel image for version 3.2.0 on 32 bit x86 SMP
ii  linux-image-3.2.0-40-generic           3.2.0-40.64                                         Linux kernel image for version 3.2.0 on 32 bit x86 SMP

ii  linux-image-generic                    3.2.0.65.77                                         Generic Linux kernel image

The update/Synaptic segfaulting was something that started after i had finished updating the system.

Thanks,

Does connecting to your router with an ethernet cable, then running
Code: [Select]
sudo apt-get update
then
Code: [Select]
sudo apt-get upgrade
then
Code: [Select]
sudo apt-get dist-upgrade
then rebooting not solve the issue ?

Ok,

I've run these commands and rebooted. Synaptic now works. The wireless is still out. I guess i'm going to have to bite the bullet and install Pep5 from scratch? Thanks again for all of your help.

Hi trkkazulu, don't do anything draconian like that yet.  I'd wait for PCNetSpec to get back to you.  He has loads of tricks up his sleeve  ;)!!

I think this is a corruption of the 3.2.0-65 kernel and supporting drivers, and/or a corrupt initrd.img

I think iit would be a good idea to boot an earlier kernel (3.2.0-40), purge the current kernel (3.2.0-65), then update again to pull back in an uncorrupted version of the most recent kernel and rebuild the initrd.img file

Do you know how to boot an earlier kernel (3.2.0-40) ?
