[pkg-wpa-devel] Bug#768862: wpasupplicant: large beacon interval is badly tolerated

[Vitez Gabor]

Package: wpasupplicant
Version: 2.3-1
Severity: normal

Dear Maintainer,

With a wifi AP with a 1 second beacon interval wpa_supplicant will take
multiple seconds to find the network, when theoretically 1 second should be
enough. Neither Android, nor Windows suffers from this problem, they both
find the network with very small delay.

Setting autoscan=periodic:-1 in wpa_supplicant.conf seems to resolv the
problem, so I propose setting the defaults accordingly. 

(The problem seems to lie in using a too short scan duration, coupled with a
too long delay between the scans, so the AP and wpa_supplicant have no
chance to find eachother.)

Kind regards
