I'm running Shibby's 112-64K AIO build on my RT-N66U. I've been using MultiSSID for quite some time now without issue. I've come across an issue I cannot figure out. Up until now, I've been running 2 virtual SSID's in addition to the 2 main ones for 2.4 and 5 GHZ. I have wl0.1 (2.4 GHz) and wl1.1 (5Ghz). I recently tried to add another 2.4 Ghz virtual SSID (wl0.2) but this time I need to give it a specific MAC for the reason listed in the link below: http://www.maxconsole.com/news/DS/Spoofing-Nintendo-StreetPass-Relays-RKSID00000000000000001287.html However, when I try to change its mac in Advanced->MAC Address, it does not change properly, thus nothing can connect to it. If I try to change the mac on wl0.2, the following message appears in the Virtual Wireless config: "warning: WL driver reports BSSID 00:00:00:00:00:00" and I can't use it. If I change the MAC on wl0.1, IT WORKS, however then wl0.2 reports: "warning: WL driver reports BSSID SameMacAsWAN"... Huh? I have tried resetting NVRAM multiple times, and tried several different combinations of config, like using wl0.3 and wl0.4 instead of 0.1 and 0.2, but it results in MAC conflicts with BSSID every time, unless I use wl0.1 only which does work for changing the MAC. Bottom line: I cannot change (spoof) a specific MAC address on any Virtual Wireless interface other than wl0.1. Am I doing something wrong?
