Title: No wireless card detected...
Post by: trkkazulu on March 10, 2015, 06:15:06 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 version of peppermint are you running? you say pep5 on usb works but you say you have 2 years work and tweaks on the machine, pep5 has been out less then a year?   :-\

sudo modprobe ath9kif wireless springs to life, we'll have to add that driver to /etc/modules so it's loaded at bootup

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?

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-releaseand

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

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.

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) ?

No need to do anythng as risky as renaming files .. the old kernels are stiil present and selectable from the GRUB menu.

Turn off your PC

Turn on your PC and immediately hit and hold the Shift key .. eventaully you'll be presented with the GRUB menu which looks something like (but not exactly) this:-

(http://shivamdixit.com/images/power-on-post/grub.jpg)

Use the up/down arrow keys to select thee one you want to boot (Peppermint with Linux 3.2.0-40-generic) and hit enter to boot into that kernel.

Be aware ..
a) depending on the GRUB version that kernel may be listed under the "Previous Linux Versions" submenu
and
b) do NOT select the 3.2.0-40 kernel line that ends with "(recovery mode)"

Once you managed to boot into the 3.2.0-40 kernel (whilst running that kernel) come back here and post the output from:
Code: [Select]
uname -aso we can check you are indeed booted into the older kernel.

modprobe -nv ath9k gives me:

lsmod outputs:

Well...

Horray, it's working! Except, it keeps dropping the connection to my wireless router. I have seen this before. It connects and disconnects. I found a fix for it long ago. I don't remember exactly what I did. I believe i included an option in a configure file somewhere. Any ideas on that?

Fantastic! Thank you ever so much for walking me through this. It is very much appreciated. I shall do a full install of Pep5 in a couple of months when I get the downtime I'll need to do that.

Thanks,

Try this .. run:
Code: [Select]
sudo gedit /etc/modprobe.d/ath9k.confwhen a BLANK file opens, add a single line that reads:
Code: [Select]
options ath9k nohwcrypt=1SAVE the file and close gedit.

Now reboot to test.

if that doesn't help, post the output from:

By the way,

I installed Wicd Network Manager a.  Phew weeks ago in an attempt to solve this problem. I had other network manage,met tools already installed prior. Shall I just uninstall Wicd? Are there any advantages to keeping it over Network Manager?

Thanks,

First see my last posting....

feel free to uninstall wicd if you wish .. we can always reinstall it if it looks like it may help, but no point having both installed.

The wireless card is connecting on reboot and then it is intermittent. Here is the output of

Hi trkkazulu, copy and paste the output to an empty Gedit file.  This is located by navigating to: menu > Accessories > Text Editor.  Save the file as, sudo-iwlist-scan to your Dropbox.  Let it sycn and then open your Dropbox account via your web browser.  Find the file, sudo-iwlist-scan and select the Share option that's located to the right of the file.  A new window will now open.  Post the highlighted URL to the forum.  I hope this helps - have fun  ;).

Edit:  Please remember to encapsulate the URL with the: Hyperlink Option.  This is located above the  ;) "wink" emoticon in the forum editor.

Hi,

This is really strange. Last night, the output of iwlist scan produced pages of data. This morning it gives this:

lo        Interface doesn't support scanning.

wlan0     Interface doesn't support scanning : Device or resource busy

eth0      Interface doesn't support scanning.

Jeez .. you're in an extremely congested wifi location .. 27 networks all trampling on each other :o

If I were you, I'd set your router to channel 8 or 4 (nobody a round you is using either of those channels) .. you might also want to set

IPv6  . Method: Ignore

for your wireless connection profile in networkmanager
