Hi there!  I set up a new Deco Mesh system following the app instructions. Everything was going great we went to set up the wireless printer. 

I went into the printer settings and manually found new Deco Network.  It is now connected to it    The printer (and HP All In One) is now showing up as a client on my Deco app.   But now, the printer is showing up as offline on MY computer which is the main system.

Here is my setup.  

ISP router is connected to my computer.  

Deco is connected to ISP router 

All lights are green.

8 devices across my house including Hubbys computer are connected to and seen by the Deco Network

HP All in One is seen by the Deco Network according to App.   

My computer is showing my printer offline, - but there.    My hubbys computer is also showing printer offline.   

How do I change my computer's Network setting.  I do NOT have a WIFi Adapter and have been just directly connected through my ISP until this point.   Is this a setting that I can change somewhere?  Or do I need to get my own Network Adapter for my computer now that I am bypassing the ISP WiFi?
