Ubuntu – Wireless card unseen by lspci

driverswireless

I installed both Ubuntu 8.04 and 10.04. I tried to install the wireless card. although I succeeded in installing the driver using ndiswrapper, it tells me that the hardware is not present.

When I use lspci, it doesn't list it. I have this laptop model and I think it should have the same entry about the wireless card here:

Could the problem be other than hardware malfunction?

Update:
Here's lspci output:

Unfortunately I'm using Ubuntu 8.04 since it is the last LTS that runs with acceptable performance.

I had similar issue where :lspci doesn't list any wireless device/card
ifconfig won't list any wireless interface
rfkill won't make any change
not able to turn on wireless
network manager won't list any wireless
dmesg won't say anything related to wireless

one thing you can see that you may have usb wireless instead of pci it is possible for internal wireless too.so see the output of lsusb and look for your wireless card. Well i wasn't able to find why this occurs i tried everything like reinstalling drivers, recompiling drivers etc but could not find a fix this way .I think there is something close to hardware (at least in my case)that's why you can not fix it using software/drivers.

I found a quick fix:
Goto BIOS settings you will probably find wireless enabled there if this is so disable it reboot again go to BIOS settings again now enable it your wireless should work now

this worked for me, try it well .I have been struggling with this and could not find a conclusion. If anyone finds it please reply.
