We do have a ring doorbell, 3 smart TV's all on wifi, an ADT security system with 2 cameras (also on wifi), the Schlage door lock also wifi... all of them work great on the wireless router. Watcha do is use one of the cable splitters & the coax cable running to the garage where the initial device is at (the Xfinity guy told me it's called an "RFoG"). Where that coax spits out the other end in your media cabinet (where the big Ruckus box is at), you attach that end coming from the garage to the splitter "in" port, you'll screw it on the coax just like you would a TV or modem. Then what you wanna do is determine which room in your house has the most central coax outlet in it, ours is upstairs in the living room. Connect your modem to that coax outlet with as short a cord as you got & that will reach a nice spot to store your modem. The next step I did was go back to the media closet & start "guess & checking" the coax cables screwing them into the "out" port(s) on the coax splitter (the one attached to the RFoG thing in the garage) till I found the one connected to the modem. I was able to do that by walking over to the modem after I tried the 1st coax & waiting a couple seconds to see if it got signal from the RFoG thing in the garage. I got it on the 3rd try so it took a few minutes but was super easy. I just tried the 1st coax, walked over to the modem, stood there 30 seconds, walked back to the media closet, unscrewed it, tried another one, walked over to he modem...

Once the modem is connect to the RFoG out in the garage you are done, unless you have a stand alone wifi router but in that case you just use one of those short yellow network cables & attach the router right there next to the modem.

The ADT cameras took a few tries to connect as I had to do a full factory reset & log them on to the new wifi (instead of the Ruckus). The 2.4ghz frequency they run on seems a little weaker than the 5.6ghz your computers & wireless devices use.

Also, FTR I am no IT professional, I was able to bypass the Ruckus in like 30 minutes by just using the wifi router was plugged into the Ruckus. The Ruckus however, I spent 2 years messing with for 100's of total hours trying to keep up & running. Even my Lennar home rep told me it was a HUGE mistake putting them in our homes & they have completely severed ties with Ruckus & their products. Good luck, glad you were willing to give it a try... wish I would've 2 years ago.
