I have ubuntu 8.10 installed on my Lenovo 3000 G430 laptop (415228Q).
Wireless worked fine initially. I once happened to close the external switch for wireless when it was connected. Then it stopped working.
Now $sudo iwlist scan gives the output:
eth1 Failed to read scan data : Invalid argument
$sudo iwconfig gives output:
eth1 IEEE 802.11bg ESSID:"" Nickname:""

Any help would be appreciated.
