Mesh network versus a simple Wi-Fi extender

I have heard recommendations against a mesh network for audio, as if the connection switches from one node to another, there could be dropouts. I have no experience with that myself, but it seems plausible. So maybe a WiFi extender would be better. Best, of course, is Ethernet directly to the streamer if possible. That avoids all vagaries of WiFi.

Like @designsfx , I’ve found find the router has a big influence, and some have worked much better than others. Currently, I’m using an ASUS RT-AX86U, not the most expensive, but an outstanding router in reliability, stability, and signal strength. It’s in the basement, and we get good coverage even on the 2nd floor.

Using the RT-AX86U, I’ve run my Auralic Aries G1 on WiFi for a few days, and the connection was rock-solid and not distinguishable from Ethernet. Your setup and results may vary.

I'm using a TP Link  Ethernet over AC adapter .   From that I have a TP Link 10 port switch .   One SFP port goes to a TP Link MC220 fiber optic converter.  This is connected to my Aurender N200 via a short ethernet cable.   I do the same thing out of the switch's SFP 2 port to my Vault 2i.    Works perfectly

I’ve got a mesh setup and the connections are stable, i.e. no roaming unless the signal drops below a certain threshold.

You almost never move your streamer through your home while playing music, so I don't think switching would be a real problem.  I do believe in keeping things simple though.  Mesh is great for large homes with lots of square feet to cover, including when you are looking for coverage say at the pool and the garage, that sort of thing.

Read the reviews on any extenders carefully too though, as I've had really mixed experiences far worse than audio quality.

You are doing yourself a disservice if you don't find a way to go hardwired to your streamer.
