Innuos with wi-fi

+1 @jperry Get a mesh system and run a good Ethernet cable from the node to your streamer. 

Let me give additional background to my question. We are starting to visit retirement communities in anticipation of having to move within a few years to an independent living apartment. This will require a drastic downsizing of my stereo system, with the Zen as the basis. The first community we visited furnished internet access though wifi with no ethernet wiring. I an not installing any internet system. I just need to know if I can get the Innuos to function with an adapter. Thanks for any help.

Probably don’t want to setup any streamer directly on a public wifi connection.

I’d look into the wireless client connect, dhcp on lan side over ethernet cable to in apartment devices.

Not sure how mesh works in this situation, but with a Wi-Fi extender you just need to plug it in near the apartment’s router and link them together, then you should be able to plug the extender into an outlet near your system and run an Ethernet cable from it to your streamer and all should be well I’d think.  That’s what I’d do. 

Thanks @soix, that's what I was assuming, and I don't anticipate streaming other than radio unless Innuos eventually adds the Amazon Prime Music stream.for which there has been no news for a while.

I may explore creating a secondary wireless node for extra security if I can ever figure out how.
