Is there a way to change this threshold to something other than 50%? https://faq.i3wm.org/question/5092/is-there-a-way-to-change-the-degraded-threshold-for-wireless-in-the-i3status-bar/?answer=5097#post-id-5097There is no easy way: 1. There is no configuration option for that in `i3status`. 2. The value is not even hard coded into the `i3status` code, but it is retrieved with the *iwlib* library, which in turn seems to get it from the driver. The `wireless.h` (from *iwlib*) has the following to say about `avg_qual` (which `i3status` uses - correctly so - as threshold value): /* This should contain the average/typical values of the quality * indicator. This should be the threshold between a "good" and * a "bad" link (example : monitor going from green to orange). * Currently, user space apps like quality monitors don't have any * way to calibrate the measurement. With this, they can split * the range between 0 and max_qual in different quality level * (using a geometric subdivision centered on the average). * I expect that people doing the user space apps will feedback * us on which value we need to put in each driver... */ struct iw_quality avg_qual; So unless there is a way to actually calibrate this setting now, it seems that the threshold `i3status` uses cannot be changed. --- Of course you could always modify the code and compile `i3status` yourself.Fri, 05 Dec 2014 08:35:44 +0000https://faq.i3wm.org/question/5092/is-there-a-way-to-change-the-degraded-threshold-for-wireless-in-the-i3status-bar/?answer=5097#post-id-5097Comment by jefeyay for There is no easy way: <ol> <li>There is no configuration option for that in <code>i3status</code>. </li> <li>The value is not even hard coded into the <code>i3status</code> code, but it is retrieved with the iwlib library, which in turn seems to get it from the driver.</li> </ol> The <code>wireless.h</code> (from iwlib) has the following to say about <code>avg_qual</code> (which <code>i3status</code> uses - correctly so - as threshold value): <pre><code>/* This should contain the average/typical values of the quality * indicator.
