How do I switch from Wi-Fi to Ethernet cables?

If you do not have wifi drop out then money best spent would be on a better streamer. Innuos Pulse Mini, Matrix Audio I2 to name just a few of the many out there.

Bluesound Node is ok but more of an entry level product. You dipped your toes in the water so now jump in and have some fun.

@calieng +1 on the Asus Ai Mesh system,I have 4 Asus Mesh capable wireless routers and it is the best wireless setup I've had in my home thus far.WAY more powerful/capable than eero and the like. The UI can put a lot of other posters issues to rest as you can see the up-down bit rates and what is connected to the network and assign bitrate priorties to a device.  What I've found is there is no appreciable difference in sound quality between wireless streaming and a wired set up (with devices I own,YMMV) as stated previously you don't need a ton of bandwidth to stream music. The OP would be wise to stick with wifi using the Bluesound Node the added preformance is likely to be not worth the headache because the Bluesound Node has an excellent wireless receiver built in. Some have experienced better results via a Lan connect but in those instances my guess would be the wireless module in the unit is likely an older wireless protacol which is not the case with the Node the real magic depends on what you are feeding the Node into for most mid teir systems much like dacs.

There is a lot of debate regarding this topic if you disagree with me fine, but please lets be adults and civil about it...

@balooo2 yes I have yet to find any issues with the equipment I have owned for wifi versus ethernet. Wifi actually isolates from electrical interference that can be picked up on ethernet cables some times.

I actually tried a Lumin U1 on a $29 Netgear mini travel router powered by the Lumin USB port and there was absolutely no change in sound from hardwiring it with ethernet. The only difference was being able to ditch a long ethernet cable running along the baseboards.

Even old Wifi N can do up to 450Mbps which would allow for a couple hundred Tidal streams at once in theory.....

Digital data transmission is basically an all or nothing proposition. If you don't have dropouts, hiccups, or pops during playback then the audio data is getting from point A to B intact. There's no logical reason for the sound quality to be different whether you're using a wireless or wired connection.

Let's think about this rationally, if wireless transmission were so fragile, why would you use wi-fi to do even more important stuff like banking online? Why would you trust a wireless system to help you navigate on a highway?

Your time and money is more effectively spent on better headphones / speakers and finding well mastered / engineered releases of your favorite recordings.

@yage You’ve obviously very little experience with various streaming setups and have no idea what you’re talking about.  Go back to ASR where you’ll find many friends and disciples.
