Topic

An updated wpa_supplicant package that fixes a bug is now available for Red Hat
Enterprise Linux 6.

Description

The wpa_supplicant package contains a WPA (Wi-Fi Protected Access) Supplicant
utility for Linux, BSD, and Windows with support for WPA and WPA2 (IEEE
802.11i/RSN). The supplicant is an IEEE 802.1X/WPA component that is used in
client workstations. It implements key negotiation with a WPA Authenticator and
it controls the roaming and IEEE 802.11 authentication and association of the
WLAN driver.

This updated wpa_supplicant package fixes the following bug:

  • Due to an error in the wpa_supplicant code, Wi-Fi signal levels for some

wireless devices reported by the Linux kernel's nl80211 API were not handled
correctly. Consequently, the NetworkManager applet did not indicate the signal
strength for unconnected networks. With this update, the code has been corrected
and the NetworkManager applet now indicates signal strength for drivers using
the nl80211 API as expected. (BZ#752032)

All users of wpa_supplicant are advised to upgrade to this updated package,
which fixes this bug.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
