How to return to default setting for "qos directed multicast" and "qos directed-threshold"

[Twilight360]

My Lennar home came with a ICX 7150-C12P switch and two R510 Access points. 

I recently purchased a SONOS system for my home but i was unaware of the native issues that SONOS has with the RUCKUS system. In attempting to make the SONOS equipment work i changed a few settings that produced for others online. 

From the command line *terminal* in MAC i made the following changes to one of my AP's *the 2.4 GHs one* .. Ruckus(config-wlan)# no qos directed multicast   

..Ruckus(config-wlan)# qos directed-threshold 0 

And indeed the SONOS system components started to find each other. That is, before all of my security cameras and smart thermostats and other gear that require a 2.4 ghz connection went offline 😞 .  No internet access on the SSID with 2.4 GHz after i made the changes. At this point i will either be returning the SONOS system or trying the BOOST module, but i just want to UNDO what i have done to the 2.4GHS network. How do i UNDO the following command lines above to return to default?  Please advise. 

I have tried the following for a fix, but still no internet access. 

ruckus(config-wlan)# qos directed-multicast

ruckus(config-wlan)# qos directed-threshold 128
