Well, probably a valid concern. But music streaming doesn’t use nearly as much bandwidth of video streaming. The better the streamer, the less susceptible to drop outs.
I am not in the habit of waiting. Good time to start and gain experience. If fiber isn’t far away, then all the better. My streamers work when my iPad will not refresh.
If your system is not close to your router so you can run an Ethernet cable, then you can use a wall wart wifi extender and plug into that. WiFi receivers inside streamers are notoriously unreliable, even good ones.
