Disable WiMAX init at Bootup?

**Elmer Fudd** · August 28th, 2011

Any easy way to stop the initialization of WiMax during bootup? I don't use Wimax and it noticeably slows down the boot up process.

Sony F-Series laptop running 10.10.

02:00.0 Network controller: Intel Corporation Centrino Advanced-N + WiMAX 6250 (rev 5f)

I'd suggest you look in the computer's BIOS first to see if there is any option to disable wimax. You might also see if there is any module loaded to enable wimax:

Code:

lsmod | grep wimax

If so, it may be helpful to blacklist it:

Code:

sudo su
echo "blacklist <some_module>" >> /etc/modprobe.d/blacklist.conf
exit

Thank you for the suggestions.
I have already tried to disable WiMax in the BIOS (unavailable) and did find and blacklist the 'wimax' module in blacklist.conf.
It still initializes and shows "WiMax ready" during bootup.
Not a big problem. Just annoying having something I don't use delaying the bootup.

Is there a wimax listing in here?

Code:

rfkill list all

If so, does it help to do:

Code:

sudo rfkill block wimax

Is that a declaration you could add without the 'sudo' to /etc/rc.local?

"rfkill list all" returns:

Code:

0: sony-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: sony-wimax: WiMAX
	Soft blocked: yes
	Hard blocked: no
2: sony-bluetooth: Bluetooth

Ran "rfkill block wimax" both in root terminal and in "/etc/rc.local" at boot. No change.
