acer_wmi module loaded in memory -> 1: acer-wireless: Wireless LAN Soft blocked: yes -> Wireless Ethernet controller [0200]: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) [168c:001c] (rev 01) not working on Acer Aspire One - Model 531h in Ubuntu 11.10
I am using an Acer Aspire One - Model 531h
In the past it has run various versions of Ubuntu without difficulty, until a few days ago it was running 10.10.
I tried 11.10 running off a USB and I was unable to enable the Wireless network. I tried again the next day and it worked OK so I took the bold step of running the upgrade from 10.10 to 11.04. The wireless continued working OK with 11.04. I then ran the upgrade from 11.04 to 11.10.
At this point the wireless stopped working. On a couple of occasions I have managed to enable it successfully and it has worked OK however for the most part it refuses to become enabled.
Googling found me two different URLs that suggested the solution described at:
http://
Namely add:
blacklist acer_wmi
to the file:
/etc/modprobe.
I tried this but the result was, not only could I not enable wireless but the option for enabling wireless became grayed out. Thus I commented out the additional entry.
Hence I am now following Mark Rijckenberg's procedure as described at:
