Post the output from:
Code: [Select]
sudo iwlist scanand
Code: [Select]
iwconfigand I'll take a look tomorrow .. off to bed now, 5am over here.

you might also want to see if unloading the acer_wmi driver makes any difference:
Code: [Select]
sudo modprobe -r acer_wmi

I'll try removing the  acer_wmi driver and see what that does. The output from iwlist exceeded the limit of this reply box. How shall i edit that so that you can see it?

Thanks and have a good night.

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.

Thanks,

Jair-Rohm

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
