Ubuntu 10.10 starts the wifi led in blinking mode.
At first this feature is nice, but after few hours it annoyed me a lot, so I found a trick to stop this annoying blinking.
Simply add the following line to /etc/modprobe.d/wlan.conf
options iwlcore led_mode=1
to do this, you can open a terminal window and then you can issue the following commands:
# sudo -s
# echo "options iwlcore led_mode=1" >> /etc/modprobe.d/wlan.conf
or you can open the /etc/modprobe.d/wlan.conf file with your favorite editor and then you shall add the new option.
