Please do a little research before trying random stuff. After checking to see if you are actually using the iwlwifi module, why not find out a bit about whether the mentioned param. is available to you and what it does:
Am I using the module. If the output from this is blank, then no:
$ lsmod | grep iwlwifi
iwlwifi 622592 1 iwlmvm
cfg80211 1331200 3 iwlmvm,iwlwifi,mac80211
Also verify with lspci -k as above:
$ lspci -k | grep iwlwifi -A2 -B2

sysfs is a pseudo filesystem with lots of info in it. cat the files here:
$ ls -l /sys/module/iwlwifi/parameters/
... to see what your current values are set at. You can install sysfstools and run this for a neat report:
$ systool -vm iwlwifi
Module = "iwlwifi"
