[/etc/modprobe.d/iwlwifi.conf]
options iwlwifi 11n_disable=1
It appears that an instruction you read is old enough that it was written, and therefor executed by you, before the file iwlwifi.conf was revised by default. Your /etc/modprobe.d/iwlwifi.conf file should read:
Code:
# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system. When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211
options iwlwifi 11n_disable=1
Please fix it with:
Code:
gksudo gedit /etc/modprobe.d/iwlwifi.conf
Use nano or kate or leafpad if you don't have the text editor gedit.
After doing so, reboot and let us see your wireless-info again.
