Public bug reported:
Steps to reproduce:
Enter BIOS setup on boot
Set WLAN to "Disabled", save settings and exit
Boot Ubuntu
Although the wireless does not show up in Network Manager applet, the wireless
light comes on. Fn-F2 (wireless switch) has no effect.
Shut down Ubuntu, start up and enter BIOS again
WLAN is now set to "Enabled"
I have no way of checking whether the radio is actually on, but I don't
want to get on an airplane if there's any doubt! Booting into Windows XP
does not show this issue (light stays off, on reboot WLAN is still
disabled in BIOS)
Workaround:
Blacklist eeepc_laptop and rtl8187se, then disable WLAN in BIOS. The light will
not come on and WLAN will stay disabled.
If only rtl8187se is blacklisted, the problem persists. The light comes
on shortly after "Loading hardware drivers" in the boot sequence,
probably when the "eeepc:" messages start showing (hard to tell
exactly!)
Conclusion: loading the eeepc support module appears to enable wireless
hardware regardless of the BIOS setting.
