Multi SSID anomaly with WPA

    I'm a newb to tomato so I'd like to assume that I've made a mistake and not found a bug, and I'm afraid I'm not versed enough with the tools available under the GUI to really make the determination, so hopefully someone more knowledgeable than me can decide if this is something that needs to be fixed.

    I set up multiple vlans, confirmed their expected behaviour, and then set up multiple-SSIDS according to teaman's howto's, plus any troubleshooting tips I could clean on their or threads here.
    In the end what I found was, Multi SSID on br1 works. MultiSSID on br3 does not.
    Changing the physical ports along with the lan bridges made no difference, so it would seem for me on an RT-N16 at least, that BR1 is somehow special and supported for multi-ssd.

    Here's screenshots of working and non working config, toggled back and forth to work and not work.
    I should say that in a previous round of troubleshooting, I found WEP to work in this setup properly and as expected, and only WPA not to work. However, I did a full flush and re-configure in between so I would like that information to be taken with a grain of salt. I did not actually try WEP a last time with this configuration as I was already exhausted with my fruitless hours of troubleshooting.

    Working configuration:

    Not working configuration:

    Thanks for any feedback. My setup is now working really well, and tomato is performing its expected functions wonderfully thanks to everyone who does work on this project.

    Unfortunately, there's still some things to be fixed in future versions of the MultiSSID GUI...

    In the meanwhile - here's something I've learned while fiddling with WPAx and wireless VIFs - the first two items bellow (MAC/hwaddr) must match the third thingie (BSSID, as reported by the wl driver):
    Code:
    root@amelia:/tmp/home/root# ifconfig wl0.1 | grep HW
    wl0.1      Link encap:Ethernet  HWaddr 02:xx:xx:xx:xx:74         # 1
    root@amelia:/tmp/home/root# nvram get wl0.1_hwaddr
    02:xx:xx:xx:xx:74                                                # 2
    root@amelia:/tmp/home/root# wl -i wl0.1 bssid
    02:xx:xx:xx:xx:74                                                # 3
    root@amelia:/tmp/home/root#
    
    Let us know how it goes!

    Hi Teaman

    Thank you for responding. I got interesting results. Tell me what you make of it!

    WORKING:

    Tomato v1.28.7495 MIPSR2-Toastman-VLAN-RT K26 USB VPN
    root@tomato:/tmp/home/root# ifconfig wl0.1 | grep HW
    wl0.1 Link encap:Ethernet HWaddr BE:AE:C5:C4:EB:5A
    root@tomato:/tmp/home/root# nvram get wl0.1_hwaddr
    BE:AE:C5:C4:EB:5A
    root@tomato:/tmp/home/root# wl -i wl0.1 bssid
    BE:AE:C5:C4:EB:5A
    root@tomato:/tmp/home/root#


    NOT WORKING: (wl0.1 bridged to LAN3, configured on same port)

    Tomato v1.28.7495 MIPSR2-Toastman-VLAN-RT K26 USB VPN
    root@tomato:/tmp/home/root# ifconfig wl0.1 | grep HW
    wl0.1 Link encap:Ethernet HWaddr BE:AE:C5:C4:EB:5A
    root@tomato:/tmp/home/root# nvram get wl0.1_hwaddr
    BE:AE:C5:C4:EB:5A
    root@tomato:/tmp/home/root# wl -i wl0.1 bssid
    BE:AE:C5:C4:EB:5A
    root@tomato:/tmp/home/root#


    There must be another issue since it only seems to be LAN1 vs LAN3 problem?

    thanks for your thoughts!

    I ran into the same issue trying to use br2. Switching to br1 got things working as expected. It does seem there is something special about br1, maybe an assumption in the code somewhere.
