Wireless adapter doesn't work in Ubuntu

Is there any way you can connect to the internet at least temporarily? You need an Internet connection to make this work

I can use wired while i set up

Hope this helps you

Hi Mark,

Please try installing wicd instead and then retest your wireless. wicd will then replace the standard NetworkManager icon.

Hi,

If wicd does not help, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (type each then hit <enter>)

sudo iwlist scanning
nm-tool
iwconfig
ifconfig
sudo lshw -C network
lspci
lsusb
uname -a
dmesg|grep ound
dmesg|grep etect

Step 3: Post results (cut/paste terminal output from each command) here

Regards,

Mark

Many Thanks for help.

I tried the advice on the above forums but couldnt locate wicd when searching for it.

I then tried the terminal advice and got the below readings

I got wicd downloaded but it doesn't see any wireless networks

I don't think it can see my wireless adapter.

When using windows I had to turn the wireless adapter on each time I booted the laptop
this is something I got used to, I don't if the fault is because the adapter can't be seen/turned on
when I load wicd it just says no wireless networks, upon reading other forums I tried the wlan0 up command
all I got was no device.

I think the first fix might be to get the device seen.

I appreciate all the help I am receiving.

Many thanks

Hi,

According to the output of lsusb (DeviceID 0bda:0158) and the information on

http://listing.driveragent.com/usb/0bda/0158?q=0bda%3A0158+realtek&PHPSESSID=1pbcuft7nst3f6rgovdsmj1h07

it seems that only a Realtek USB card reader is plugged into your pc, and not a USB wireless adapter.

lsusb says that no wireless USB cards are present. And lspci also does not see any internal PCI wifi cards....

Can you try plugging in a different model of USB wireless card?

Regards,

Mark

I could get a new external USB wifi adapter,
but if course it would be better to get the internal one working,

I don't know if there is a code to turn it on, it's an internal USB adapter,
and the only way of turning it on in windows is by pressing fn + f10,
when I installed ubuntu all other fn + ? keys works (sound, brightness, sleep etc)
but not f10 for turning the wireless adapter

I think that's why ubuntu can't see it, if there was something I could do to turn it on
then ubuntu will see it.

I will reinstall windows to get more information (where it is plugged etc) and then I will post.

Once again many thanks

I re-installed windows vista and got the following information...

This information was from within windows vista driver information, i still have windows vista on laptop if more information is needed, if no more information is needed i can reinstall ubuntu 8.10

Is there a way i can start the wireless adapter in ubuntu.

Many Thanks

I found this

http://www.thinkwiki.org/wiki/How_to_get_special_keys_to_work

but i dont know what to do with it, i think the problem is Fn + F10 (symbol with wireless) not working in ubuntu,
when i press Fn + F10 in windows it turns on adapter, in ubuntu it does nothing.

there is also an led indicator showing when the adapter is turned on.

Many Thanks

Additional Information

I dont know if it makes a difference but i had a previous problem as posted at
https://answers.launchpad.net/ubuntu/+question/54867

Ubuntu when installing frozze my system, to make it work i had to add

acpi=off
noapic

It then frozze when booting so i added the above permantly it now boots everytime.

I dont know what they mean or what they do, just remembered it.

Many Thanks

I plugged an external belkin USB adapter in, and wireless worked fine,

Is there a way i can enable the Fn + F10 key combination to turn my adpater on, or this there anything else i can do.

Many Thanks

Hi,

I don't think the FN+F10 key combination (for activating wireless) will ever work in Ubuntu. I think that is something specific for Windows (drivers) and not supported in Linux.

Please try the following workaround in Windows to try to keep the Realtek wireless card active after booting into Ubuntu:
