Lumin U1 Mini - how to set up Network *without* Ethernet cables?

Thank you so much for all the helpful posts. Love this community even if I've been more an observer for a few years. 

Lumin U1 is ultimately not for me. My honest "review" if I am qualified to do that.

First the basic lack of features. 

1. Ethernet-only was a disappointment and should be mentioned more prominently in their brochureware. I tried it with Eero 6 Pro and the speed etc is fine, but even more cable spaghetti everywhere needs to be called out.
2. iPhone app is horrid. Like, really horrid. iPad-only is a stupid decision. Not everyone will lug an iPad around their home at all times. 
3. Their manuals need help too, as does their support. 

Most importantly the sound quality. My comparison is with Lindemann Limetree Bridge II that this was meant to replace. The Bridge is a tiny German made device, which unassumingly produces stellar sound -- and I thought their app was 'basic' until I saw this Lumin rubbish. The Lumin SQ is not all as stellar as raving fanboys make it out. What were they listening to before? Coming from Bridge II there's absolutely no sonic difference. 

My chain: 
Streamer (Bridge II or Lumin U1 Mini) --> RME DAC --> Dynaudio powered speakers so amp is built in  

When I had gotten Bridge II from Hifishark I was moving from Node 2i. It was a huge and audible upgrade. Node has horrid networking issues even in its version 3 (which is just called Node) and the sound was stupid, worse than my Mac Mini before. Bridge II brought joy. 

I thought I was 'upgrading' from Bridge II to the raved-about Lumin. Not at all. The streamer's job is to unintrusively pass high end signals to my DAC. The RME is a joyful piece of kit (I've also tried Denafrips Aries II and all the foaming adulation is similarly unclear to me; Aries II was an improvement over Modius for sure, but RME is perfect for me--transparent, lovely sound stage, no coloration added to make it "analog" and all that pablum) and I think the biggest difference comes from speakers anyway. 

Net net: U1 sent back. Pointlessly large piece of kit when we have options like Limetree Bridge. 

How were you using it? Usb would be your best option from the streamer to the dac

Also upconverting to dsd sounds far better then 16 44k

That is done in the options menu set custom sampling 16 44k  all to dsd and then listen to it

Your bridge or streamer affects SQ very little if at all it just needs to get the stream to the DAC. The Limetree should be fine or even a raspberry pi. I use the Lumin U1 mini as a Roon endpoint and it has AES3 out which I need I don't exect it to improve the SQ. 

Sounds like the OP bought Lumin used without doing much research at all then Wanted this forum to do tech support….😉

First, a wireless access point is super easy to buy, install and integrate with any streamer. It’s also about $25.

since you didn’t know that, I pretty much discount what you say across the board….

if you can tell the difference between some German bridge and a Node 2i but can’t understand a wireless access point, the. You live in a parallel universe to mine…😂😂😂😂

If you never used the Lumin hard wired then it’s not a fair comparison. And as far as the phone is concerned, any app will look and perform better on a larger platform. I love using an iPad to control my music. I don’t wander around the house, I sit in the listening chair and it’s perfect for that.

Sorry it didn’t work out for you, but I think the U1 mini is a great value when you look at all it does. I came from a Node, an Allo Digi One before that,  SB Touch before that. It certainly sounds better than all of those. Look on the bright side, you just saved yourself 2k.
