11.04 Natty wireless issue - Acer - Device not ready

[Soec]

I had a similar problem: Whenever I did "rfkill unblock all", my wireless would go from
Soft blocked: Yes
Hard blocked: No

to

Soft blocked: No
Hard blocked: Yes

Tantalizing, isn't it? In the end, I created the following script as a (barely acceptable) solution:

sudo rmmod -f ath5k
sudo rfkill unblock all
sudo odprobe ath5k

I hope this script helps someone. In the time being, if anybody knows how to make this permanent, that will be much appreciated.

I am using a Natty Narwhal, (Ubuntu 11.04) running on Fujitsu Siemens Amilo PA3515 with an Atheros AR5001 wireless module.

Hope this helps,
Shoka

I have almost the same problem, but your script doesn't help me... It happened to me whenever I disabled/enabled wireless again. Thank you anyway.

It's not tantalizing; it's maddening! However, it is wonderful that you found a fix. I think you will help a lot of searchers.

In the time being, if anybody knows how to make this permanent, that will be much appreciated.

Please do:

sudo gedit /etc/rc.local

Add your three lines above exit 0 without sudo:

rmmod -f ath5k
rfkill unblock all
modprobe ath5k

Proofread carefully, save and close gedit. Reboot and tell us if it's working as expected.

Thanks Chili, just added those to rc.local, and it works perfectly.

I had thought that rc.local wasn't supposed to be used, that we all should use update-rc.d, but I guess whatever works, works.

This has worked like a charm for me too!

Thanks so much for your help shokalabutcha and chili555!
Wifi missing was a real nightmare

Finally... thanks for the fix chili555. My acer tm8372t now has wifi.

Please let us see:

sudo rmmod -f acer-wmi
sudo rfkill unblock all
rfkill list all

Does your wireless work now? We can amend two files and make it permanent.

Hey Chilli, I need your help. I had the same issue with acer-wmi blocking my sony-wifi in software switch. I followed your commands:

sudo rmmod -f acer-wmi
sudo rfkill unblock all
rfkill list all

and it worked, and i could see my wireless and it was working and everything was working and fine.

In order to make it permanent i then did

sudo gedit /etc/modprobe.d/blacklist.conf

added line in the end

blacklist acer-wmi

sudo gedit /etc/rc.local
rfkill unlock all

and when i rebooted. I do not see any phy0 in 'rfkill list all' output and there is no wireless option in panel.

It seems my drivers are gone or what i do not know.

Here is the current rfkill list all output:

vycas@vycas-VPCYA15FG:~$ rfkill list all
1: sony-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
2: sony-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
3: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

Also the lspci output (it sees the ath9k wireless)

Ok i tried the

modprobe ath9k (since i have ath9k)

it reinstalled the phy0 and then i did the sudo rmmod -f acer-wmi

and it works, but only for few minutes after that it just looses too much packets. I pinged my router and it lost 70% of packets and i am literally 2 feet away from it.

After rebooting acer-wmi always appears, so i have added these commands in following sequence in /etc/rc.local

sudo rmmod -f acer-wmi
sudo modprobe ath9k

My wifi shows internet is connected, but it doesn't work. ping works but its too slow and latency is way too high.

Hi, make sure you did it just like post 12 says.

Set your router to wpa2 and not mixed mode or wep, then post back and we will go from there.
Thank you
