My router broke down(ordered another but it will take weeks to arrive) so I had to setup an old netbook to do the job temporarily. It's running Windows 10's(I couldn't get hotspots working on Linux) native hotspot program. I can connect game consoles, phones and computers(the limit seems to be 100 devices, and I had 5 devices connected at once), but not this one laptop. I know the networking works because I'm using my Android's hotspot ATM.

Now this laptop is running Arch, tried Netctl, Wicd and NetworkManager and the two former connected to the hotspot but couldn't obtain IP address. I then tried some live disks I had laying around(Kali and Mint) and both had the same problem as Arch.

$ lspci -knn | grep Net -A2

(it is connected right now to a different hotspot)

$ iptables -S 


Tried ifconfig up / down, iwconfig power off, played around with modprobe configs(deleted now)...

The settings of the hotspot seem fairly standard, nothing Linux would have problems with(since Android and PS4 are fine with it).

I'm not sure which logs or outputs exactly would be helpful in this situation...



You need to install the linux-firmware package

Load the iwlwifi module:

modprobe iwlwifi 11n_disable=1 swcrypto=1 

Then create a /etc/modprobe.d/iwlwifi.conf file with the following contents:

options iwlwifi 11n_disable=1
options iwlwifi swcrypto=1
  • I tried those modprobe confs earlier with no luck. linux-firmware is installed. Thanks still. – Jareg Sep 20 '16 at 20:42

    Are you sure you shouldn't be doing the modprobe after you've set up the configuration file for loading the module? – roaima Sep 20 '16 at 21:38
  • @Jareg Please edit your question by adding the output of lspci -knn | grep Net -A2 – GAD3R Sep 20 '16 at 21:50
  • @roaima Tried doing it both ways, still wouldn't work :-( – Jareg Sep 20 '16 at 22:04
