Why Is My Sonos Arc Soundbar Audio Out of Sync With TV Video Lip Sync Delay

Device: Sonos Arc (Sonos Arc, Sonos Beam Gen 2, Sonos Ray)

What Is the Difference Between SonosNet and WiFi Mode and When Should I Switch?

Device: Sonos Speaker System (All Sonos Speakers with Ethernet: Sonos Arc, Sonos Beam, Sonos Five, Sonos Port, Sonos Amp, Sonos Era 100, Sonos Era 300)

You are confused about whether your Sonos system should run on SonosNet or WiFi mode and which provides better performance. SonosNet is a dedicated wireless mesh network created when you connect any Sonos speaker to your router via Ethernet cable. It operates on a separate wireless channel from your WiFi so Sonos traffic does not compete with your other devices. WiFi mode connects each speaker directly to your home WiFi router. Understanding when to use each mode and how to switch between them resolves many Sonos connectivity and audio dropout issues.

How Do I Move All Sonos Speakers to a New WiFi Network?

Device: Sonos Speaker System (Sonos One, Sonos Era 100, Sonos Era 300, Sonos Arc, Sonos Beam, Sonos Ray, Sonos Move, Sonos Roam, Sonos Five, Sonos Sub, Sonos Port, Sonos Amp)

You need to move your entire Sonos system to a new WiFi network after changing routers, switching ISPs, or moving to a new home. Sonos does not offer a one-click network migration tool. The process depends on whether you have any Sonos speaker wired to the router via Ethernet. If one speaker is wired it creates a SonosNet mesh that other speakers use instead of WiFi making migration simpler. If all speakers are on WiFi each must be individually reconnected. This is the number one Sonos complaint on Reddit with threads receiving hundreds of comments from frustrated users.

Why Won't My Sonos Speakers Reconnect After Router Change?

Device: Sonos Speaker System (All Sonos Speakers including One, Era 100, Arc, Beam, Five, Move, Roam, Port, Amp)

After replacing your router or mesh WiFi system your Sonos speakers will not reconnect. The Sonos app shows no products found. Speakers may show LED activity indicating they are powered on but the app cannot discover them on the new network. This is different from a simple WiFi password change because the entire network infrastructure has changed. Sonos speakers store the old network configuration internally and will keep trying to connect to the old network until manually reconfigured.

This pattern repeats throughout the day disrupting music and smart home automations. Unlike a one-time disconnection this recurring pattern points to a systematic network issue.
