ubuntu 8.10 not working with RTL8187b wireless


Ok, I've been using linux for about a year but I'm not a programmer or anything. I recently got a Toshiba Satellite L550 that has a Realtek 802.11b/g wireless LAN. I am using ubuntu 8.10 and everything I've read on this forum and others states that this version of ubuntu can use this device. However, it seems that my system doesn't even know the device is there. When I run "sudo lshw -C network", I get this:

None of the descriptions show a wireless device? I'm not sure what this means or what the next step is. My wired connection works fine. Any help would be greatly appreciated. Thank you.

I've checked the link you gave before but didn't give it much mind because I didn't think it applied to 8.10 ubuntu. So, does the lsusb show that I have a 8198 instead of the 8187b listed on the bottom of the laptop? Thanks for trying to help.

Apparently it mis-identifies the device, it should still be the 8187b.

Have you tried
sudo modprobe rtl8187

Modprobe installs the module into the kernel.
Use your network manager to find the device and use it.

I asked for lspci to see if it was there. It's not. smoker correctly had you check into lsusb (it is a usb device) and gave the proper instructions (thanks smoker).

so I typed "sudo modprobe rtl8187" into the terminal but there doesn't appear to be any change...the network manager still doesn't show any wireless devices/connections? maybe I missed a step? using the teminal is a bit new for me. i've used it to add wine and that's about it. again thanks very much for trying to help me with this.

run
lsmod

and see if the module was loaded.
If it was then this explains it better than I can. :
https://help.ubuntu.com/community/WifiDocs/WiFiHowTo

I suggest getting wireless-tools as described on that page, and proceeding from there.

The system may just need a restart. Sounds like a m$ solution, I know, but try
Code:
sudo /etc/init.d/gdm restart
PS: I would read the link smoker gave regardless
