I’m seeing a lot of posts reference lar_disable like this one for instance. I’m wondering what it does. modinfo iwlwifi just says,

What is “LAR functionality”?

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

LAR means Location Aware Regulatory

I searched LAR in the source code of Linux wireless driver, only Intel use the LAR term in their code.
In their code comment [1, 2, 3] mention the full form of LAR

Solution 2

LAR functionality is a reference to Location-Aided Routing Protocols.

Example papers:

  1. Location-Aided Routing (LAR) in Mobile Ad Hoc Networks
  2. Secure Location-Aided Routing Protocols With Wi-Fi Direct For Vehicular Ad Hoc Networks

Note: Use and implement solution 1 because this method fully tested our system.
