lspci -vnn | grep -i netand what happens now if you run:
Code: [Select]
sudo modprobe ath9k

Check this out,

Very strange. The ouput from "sudo lshw -C network"

then:
lspci -vnn | grep -i net
03:00.0 Network controller [0280]: Qualcomm Atheros AR9462 Wireless Network Adapter [168c:0034] (rev 01)
04:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink BCM57785 Gigabit Ethernet PCIe [14e4:16b5] (rev 10)

and finally:
sudo modprobe ath9k
FATAL: Error inserting ath9k (/lib/modules/3.2.0-77-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Just as a test, what happens if you install the latest comat-wireless bacport:
Code: [Select]
sudo apt-get install linux-backports-modules-cw-3.12-3.2.0-77-genericthen reboot ?

then what's the output from:
Code: [Select]
lsmod | grep ath

Ok,

modprobe -nv ath9k gives me:
 
insmod /lib/modules/3.2.0-77-generic/updates/cw-3.12/ath9k.ko nohwcrypt=1 pio=1  qos=0

lsmod outputs:

sudo modprobe -r acer_wmi outputs nothing and then:

sudo modprobe ath9k
FATAL: Error inserting ath9k (/lib/modules/3.2.0-77-generic/updates/cw-3.12/ath9k.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Something very strange here, no?

grep -R 'pio' /etc/modprobe.d

The output of that command is:

/etc/modprobe.d/ath9.conf:options ath9k pio=1

Thanks.

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:
Code: [Select]
grep -R 'ath9k' /etc/modprobe.d

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
Code: [Select]
grep -R 'ath9k' /etc/modprobe.d
/etc/modprobe.d/ath9k.conf:options ath9k nohwcrypt=1
