Ruckus R500 - Second Owner

[david_gig]

Recently purchased a newer home (am now the 2nd owner). The builder had installed the Ruckus R500 and the previous owner appears to had been utilizing it as his wifi name keeps appearing as a network option. Where do I start as far as accessing and changing the password, etc. I have accessed the unit and see the reset, etc. Currently have an ISP and this would be for home use along with the basic devices - laptop, phone and tablets. Would I do a reboot or reset as I have researched? This just appears to be a little out of my league but hoping someone can point me in the right direction - thanks!
