Another possibilities to get WIFI working in Ubuntu 10.10 :
- temporarily hard-wire your laptop to the router
- open a terminal window (Applications/Accessories/Terminal) and type:
sudo apt-get update
- NOW do as suggested - look in System/Adminnistration/Hardware Drivers and see if a driver is listed for your adapter - if so, enable it. It may download something from the net then.
- physically disconnect the hard-wire connection to your router
- right-click the network manager icon - be sure "Enable Wireless" is checked
- left-click the network manager icon and see if wireless networks now show
- remember that if you use encryption you will need to supply the type and the password/passphrase when you try to connect
- if you use MAC filtering on the router, be sure to update the table to include the MAC of this laptop
If you can't do the above, then please do the following:
- open a terminal window (Applications/Accessories/Terminal)
- type each of the following and post the outputs back here in a reply:
lscpi
lsusb
ifconfig
iwconfig
lshw -C network
