Subject: [PATCH] Fixed BSSID step 3: Don't merge with the same BSSID
Date: Tue, 06 Jan 2009 03:01:30 +0100 [thread overview]
Message-ID: <20090106020130.302750@gmx.net> (raw)
[-- Attachment #1: Type: text/plain, Size: 1263 bytes --]
It's completely unnecessary to merge with same BSSID. Because here in our city networks we have many of the same BSSID (and SSID) with deferent timestamps, this causes problems.
See the bug report here:
