[atlanta_kjd]

Hi,  I just bought WZR-600DHP from amazon and trying to configure the wireless, This is not explained fully, I like to verify that my assumption is correct.

I see that there are 2 wireless interface on my device "Wireless Physical Interface ath0 [2.4 GHz]" and "Wireless Physical Interface ath1 [5 GHz]"  am I correct to assume that I can assign the same SSID for both interfaces using the same password, and this will give my AP pretense in 2.4GHz and 5 GHz?

If I want to add a guest network I can just add a virtual interface to eth0 and follow the tips in http://en.faq.buffalo-global.com/app/answers/detail/a_id/14623 to finish it up?
