I just installed Ubuntu 10.04.3 to dual-boot with Windows. I can connect to the Internet using a wired connection, but not through wireless. The first time I booted, the wireless notification bar said "Device not ready". The next time I booted, the wireless notification didn't show any available networks, but did not say "Device not ready". The third time I booted, the Internet icon does not show at all.
I am conjecturing that this is a driver / hardware issue, but don't have enough experience to know.
My question is: What is the next troubleshooting step (if any) based on the steps I have already taken?
The hardware Wi-Fi button is in the on position :-) but the indicator light is not toggling with the button. i.e., when I have the wireless device in the on position while running Windows, the light is blue. When it's off, the light is orange. In Ubuntu, it is showing orange in both positions.
When I log on to the system, I get a dialog box that says something like, 'The configuration defaults for GNOME Power Manager have not been installed correctly, etc.' (I don't know how this affects the process, but hopefully you do :-)
Summary of troubleshooting steps (with outputs listed far below):
Stepped through the pertinent troubleshooting steps at the Ubuntu Community Documentation
a. Checked for device recognition with
sudo lshw -C network(output below)
b. Checked for a connection to the router with
c. Checked ip assignment with
- Ran the "Hardware Drivers" utility in System-->Administration (it said 'There are no proprietary drivers on this computer')
- Identified my card and driver with
lspci -vvnn | grep 14e4(output below)
- Checked linuxwireless.org to see if the driver is supported (it is)
What's my next step?
