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

    While it is perfectly fine and appreciated to answer your own question in order to share knowledge or because you simply found the solution yourself later, please adhere to the site's Question & Answer format. In other words, describe only the problem in your question, and put the solution in the answer post. Putting both in the question and/or adding an answer without actual content like this one is not okay. Please edit your posts accordingly. Thank you :) – Byte Commander Jul 06 '20 at 23:18
