[pkg-wpa-devel] Bug#795722: please include patches to improve 2.4/5 GHz AP selection

[Steinar H. Gunderson]

Package: wpasupplicant
Version: 2.3-2
Severity: normal
Tags: patch

Hi,

2.4/5 GHz selection in wpasupplicant is currently very poor, which impacts
things like e.g. the DebConf network negatively:

  14:21 < jcristau> 285 clients on 2.4GHz, 126 on 5GHz

wpasupplicant upstream recently included a series of patches to improve
selection significantly:

I've run with all of these four patches now for a few months, and it works
great for me. I also got reports from DC15 that it helped performance there.
Please consider applying them on top of 2.3.
