Intel Wireless 7260 card doesn't connect to WiFi sometimes
(Also posted in Reddit)
I have a strange problem. My machine sometimes (more often no than yes) doesn't connect to my home wifi. I can connect to android devices hot spot easily. Windows machine connects as well. Finally, I can use my android devices as a usb wifi card. I know I should put some data here, I don't what technical data I should put, but here are some anecdotes:
- Currently, my home network doesn't have a password, or spaces in its name.
- From my experience, if I wait long enough (like an hour) the chances are it will connect are higher.
- This might be a coincidental, but often, the machine connects right after I plug my phone as WiFi card.
- I have two Lenovo machines (Edge 13 and ideapad u330p) both doesn't connect. The Edge machine currently runs Arch, but Ubuntu didn't connect with it as well. Interestingly, live USB of Lubuntu connected on the edge machine.
I'm more concerned about the ideapad machine as the edge machine is soon to turn into a stationary machine that connects via cable. So, how do I avoid/handle the mishaps?
Things I have tried:
-
Updating the Intel firmware - It still doesn't connect. I note that to stop
iwlwifiI have to stop bothiwlmvmandiwldvm.
Here is the output of the linked script. I'm at the campus right now, so things might not seem exactly as I described them. To my understanding, the issue is with network card (intel 7260) which has new firmware available, only I didn't find anyway to activate it.

########## wireless info END ############
After have wireless issues myself with my Intel wireless card I researched a bit and found a few commmon attempts to fix it. I've done these myself and have much better stability on my laptop.
I don't recall the exact site I followed, but a quick google search jogged my memory and these are the two things I did ( from http://itsfoss.com/speed-up-slow-wifi-connection-ubuntu/ )
1) Disable 802.11n
sudo rmmod iwlwifi
sudo modprobe iwlwifi 11n_disable=1
That will make the change until the next reboot. Test it and see if you have a more stable connection to your wireless AP. If so, you can make it permanent by doing the following (you can always revert this change by editing that file and removing the line it adds)
sudo su
echo "options iwlwifi 11n_disable=1" >> /etc/modprobe.d/iwlwifi.conf
2) Disable wireless card power features
sudo iwconfig
It will give you the name of your wireless device. Normally it should be wlan0. Now use the following command:
sudo iwconfig wlan0 power off
