Wifi adapter lost after installing ndiswrapper

[bonehunter]

Hey guys after endless searching google and forums I hope to get help here. But first of hello to all and thanks in advance.

Now to my problem;

I installed on my Laptop Acer Aspire 5750G running Ubuntu Linux 12.04 Lts ndiswrapper through Ubuntu Software Center. After installation I installed through gui an Windows wireless driver which I used in Windows 7 x64 same notebook. After installation it showed up in ndiswrapper hardware found: yes.

Atheros Wireless Adapter AR9287

But!!!

I lost actually my wifi adapter, which means there is no possibility to reach my wifi adapter or to connect to wirless lan. I can only plug a cable to my computer to get Internet access.

So again what happened to my computer? I removed diswrapper but could not get the previous configuration back.

No I´m whithout any clue or idea what to do!

Thanks guys quite a lat for any help you can provide.

Let's see if this gets you moving in the right direction...

He has Ubuntu 12.04 Precise Pangolin , not 10.04 Lucid Lynx.

I suggest

1) First remove completely the ndiswrapper .

sudo modprobe -rf ndiswrapper 
sudo apt-get remove --purge ndiswrapper-common ndiswrapper-utils-1.9 ndisgtk 
sudo rm /etc/modprobe.d/ndiswrapper.conf 
sudo rm -r /etc/ndiswrapper/*  
sudo depmod -a

Reboot your PC
Then give the results* of bellow commands

lspci -nnk | grep -iA2 net 
lsmod 
ifconfig 
nmcli nm status
rfkill list all
nm-tool

*Put the results between the brackets [code]Here[/code].

Thanks
