Subject: [PATCH] Fixed BSSID step 2: Don't scan if BSSID and channel are set manually
Date: Tue, 06 Jan 2009 02:49:07 +0100 [thread overview]
Message-ID: <20090106014907.302730@gmx.net> (raw)
[-- Attachment #1: Type: text/plain, Size: 1033 bytes --]
If you set a fixed BSSID and channel it's not necessary to scan for neighbors to merge, because you really don't want to merge with it. So don't do it.
