I believe your wireless card uses the driver module iwlagn. Check with:If it is indeed iwlagn, let's try a temporary fix:Code:lsmod | grep iwlNow does the LED behave as expected? If so, let's write a simple file to make it permanent:Code:sudo modprobe -r iwlagn sudo modprobe iwlagn led_mode=1Add one line:Code:sudo gedit /etc/modprobe.d/iwlagn.confProofread carefully, save and close gedit.Code:options iwlagn led_mode=1
You should be all set.

The LED blinks to show send-receive activity in addition to wireless on-off.
What do you mean by "work as it should?" Isn't that what you want, Doc?

I do, and many of us do, but many others are offput by the incessant blinking (nagging? sorta like my ex??) and would prefer a simple ON if the wireless is connected and OFF if it's not. The developers of iwlagn and a few other wireless drivers give us the option to select.
If he were using most other drivers, I would have said, "I can do nuthin' fer ya, son."

A great place to start with driver issues is:In this case:Code:modinfo <your_driver>Have fun and keep learning!Code:$ modinfo iwlagn filename: /lib/modules/3.0.0-14-generic/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko license: GPL author: Copyright(c) 2003-2011 Intel Corporation <ilw@linux.intel.com> version: in-tree: description: Intel(R) Wireless WiFi Link AGN driver for Linux firmware: iwlwifi-5150-2.ucode <snip> srcversion: 8BCB911ABE7887D81943F53 alias: pci:v00008086d00000892sv*sd00000466bc*sc*i* <snip> depends: mac80211,cfg80211 vermagic: 3.0.0-14-generic SMP mod_unload modversions 686 parm: led_mode:0=system default, 1=On(RF On)/Off(RF Off), 2=blinking (int) parm: no_sleep_autoadjust:don't automatically adjust sleep level according to maximum network latency (bool) parm: bt_coex_active:enable wifi/bluetooth co-exist (bool) parm: swcrypto:using crypto in software (default 0 [hardware]) (int) parm: queues_num:number of hw queues.

Where does one find details to help understand [aka, decode] the details one learns from modinfo?
If I need to set led_mode with each system startup, which script or job or whatever-they-get-called-this-week do I use to hold the proper commands that run during system start?

You write a .conf file as above so that the driver name is here:And here:sudo gedit /etc/modprobe.d/iwlagn.confThat means, roughly, 'when you load iwlagn, as you would automatically based on the pci.id, load it using an available parameter led_mode and set it to 1.'options iwlagn led_mode=1
You can also find parameters in the driver's dependencies:Code:$ modinfo iwlagn filename: /lib/modules/3.0.0-14-generic/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko license: GPL author: Copyright(c) 2003-2011 Intel Corporation <ilw@linux.intel.com> version: in-tree: description: Intel(R) Wireless WiFi Link AGN driver for Linux <snip> depends: mac80211,cfg80211 <snip>Code:$ modinfo mac80211 filename: /lib/modules/3.0.0-14-generic/kernel/net/mac80211/mac80211.ko license: GPL description: IEEE 802.11 subsystem srcversion: 64349C3033DDDABE80DEBE4 depends: cfg80211 vermagic: 3.0.0-14-generic SMP mod_unload modversions 686 parm: ieee80211_default_rc_algo:Default rate control algorithm for mac80211 to use (charp) parm: max_nullfunc_tries:Maximum nullfunc tx tries before disconnecting (reason 4).
