My laptop is the Acer Aspire 5750 and I have an aftermarket Intel 7260 card in it.

After installing Manjaro, I realized that my wifi card was not working. I installed Ubuntu later, and had the same problem.

What could be the problem?

I wanted to make this post to share knowledge as it is something that I have fixed with the help of tbg on Manjaro Forums.

After going through a process of troubleshooting (on this Manjaro forum post) with the advice of tbg I blacklisted the btusb and acer_wmi in the /etc/modprobe.d/blacklist.conf file. After I blacklisted the module the wifi started working.

When I installed Ubuntu, the wifi stopped working so again I blacklisted the btusb and acer_wmi modules and after rebooting the wifi started working.

Blacklisting a module prevents it being loaded into the kernel at boot time. To do this, either edit the main file /etc/modprobe.d/blacklist.conf, or make a new file in the same directory with the suffix .conf, for example sudo touch /etc/modprobe.d/wireless-fix-blacklist.conf In either case, add a line for each module to be blacklisted like this, optionally with a comment to remind your future self why you did this:

# these prevent wireless from working
blacklist btusb
blacklist acer_wmi
