Lenovo 3000 N200 Wifi, Intel Pro/Wireless 3945ABG

[chris325]

So I've decided to convert my Lenovo into a Ubuntu boot, problem is I cant ge the wifi to work on either my USB adapter or my internal wifi card.

Both networks are coming up, but disabled up in the taskbar, and when I try to enable wifi it just immediately turns back off.

rfkill list gives no soft blocks or hard blocks.

My wireless card is the Intel Pro/Wireless 3945ABG [Golan]

and my USB wifi is the Realtek 802.11n WLAN Adapter.

Any help from some Linux masters would be appreciated because I'm royally stuck . Thanks for the time.

Please detach the USB as we'll fix the Intel and we don't want to fight any conflicts. Then show us:

iwconfig
rfkill list all
dmesg | grep iwl

Thanks.

Can you unblock and therefore start the wireless with:

sudo rfkill unblock all
rfkill list all

What wmi module is loaded?

lsmod | grep acer

[chris325]

After I do the sudo rfkill unblock all it still shows up soft blocked.

[chili555]

How about if we unload acer-wmi?

sudo modprobe -r acer-wmi
sudo rfkill unblock all
rfkill list all

If this helps, we'll blacklist acer-wmi.

[chris325]

Yes that did it! You're the best, it's amazing how I've been looking for this command for a few weeks now and it's such a tiny command.

Let's blacklist the module so it doesn't interfere any more:

sudo -i
echo "blacklist acer-wmi"  >>  /etc/modprobe.d/blacklist.conf
exit

You should be all set.

Glad it's working. Please use thread tools at the top to mark Solved.
