That said, if I were you I would try powering down all the speakers and your router. Leave it a few minutes, then power up the router. Wait for it to fully restart and for wifi to be running. Then power up your speakers, one at a time. Start with any wired speakers, and with Arc before Sub.
That will ensure fresh ip addresses are allocated. If that does help, try setting ip addresses for your devices to prevent any duplicate IP address problems in the future.

When I wrote “after rebooting speakers/router”, this is exactly what I did. And it didnt help.
Including waiting for wifi to be running?
Can you temporarily run an Ethernet cable to the Arc and see how things go?
Do you just have Arc and Sub or other devices too? Running on wifi? Or SonosNet? Ethernet?
