WiFiXpert Compatibility Score — Sonos Arc
Excellent sound, but it leans heavily on the background chatter that keeps speakers grouped together.
Plays nicely with almost any Wi-Fi
Eight checks, same for every device. The eight numbers below add up to 82.
The eight checks
| What we check | Rating | Points |
|---|---|---|
Works on 2.4 GHz Connects happily to the slower, longer-range band, which is why it usually works in a back room. | Excellent | 14/14 |
Works on 5 GHz Uses the faster band when the signal is strong enough — good for high-quality streams. | Supported | 12/14 |
Modern Wi-Fi security Newer Sonos software handles modern security fine; older speakers in the same system can force the whole network to be set up the old way. | Depends on the model and software | 10/12 |
Happy on mesh Wi-Fi Generally settles on the nearest mesh box, though a speaker fixed to a wall can hang on to a distant one. | Good | 14/16 |
Works on a guest network Guest networks stop devices talking to each other, and your phone then can't see the speaker at all. | Poor | 3/8 |
Survives a plug-in extender If the speaker and your phone end up on different halves of an extender, the app loses the speaker. | Issues possible | 5/8 |
Doesn't depend on chatty discovery Sonos relies on constant background 'who's here?' messages. Routers that filter them cause speakers to vanish. | Significant dependency | 12/16 |
Easy to fix when it goes wrong Usually fixed by putting phone and speaker on the same network name, but people rarely guess that. | Medium | 12/12 |
| WiFiXpert Compatibility Score | 82/100 | |
What usually goes wrong
Speakers disappear from the app, especially after a new router or mesh system arrives.
Free things to try, in this order
- 1
Put your phone on the same Wi-Fi name as the speakers — not the guest network, and not a separate 5 GHz name.
- 2
Give your main Wi-Fi one name for both bands rather than two separate names.
- 3
Turn off any 'client isolation' or 'AP isolation' setting on your router.
- 4
If you have a plug-in extender, unplug it and see whether the speakers come back.
Before you buy anything
Only if the room genuinely has no signal. A wired connection to one Sonos speaker fixes far more homes than new kit does.
Using it with your router or mesh
Answers about this gadget
What it needs from your network
Dual-band Wi-Fi client that must stay on the same subnet as your phone and every other Sonos device.
- Bands it uses
- Both bands, though older units in the same system can hold the whole system back.
- How it's found
- Heavy. Grouping, control and playback all depend on speakers finding each other continuously.
- Background discovery traffic
- Critical. This is the single biggest cause of speakers disappearing.
- On a guest network
- Unsupported. Speakers on a guest network cannot be grouped or controlled.
- On a separate gadget network
- Splitting speakers from phones needs discovery traffic forwarded between the two networks. Most home routers cannot do it.
Getting it set up
- • Everything must be on one network name — main network, not guest.
- • Add speakers one at a time and check each appears before moving on.
- • Stand next to your router while you set it up, then move the gadget to where it lives.
- • Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
- • If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
- • Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.
With mesh Wi-Fi
- • Wired backhaul between mesh boxes helps enormously.
- • A speaker that is fixed in place can cling to a distant mesh box — power-cycle it once the mesh is settled.
With particular broadband providers
- BT: BT Smart Hub 2 splits nothing by default, which suits Sonos — but its guest network fully isolates devices.
What to do: Keep the phone and speakers on the main network name.
- Sky: Sky Broadband Hub gives very few settings, so there is little to adjust when a speaker vanishes.
What to do: Restart the speaker first, then the hub; check no separate 5 GHz name has been created.
- Virgin Media: Homes running a Virgin hub plus a separate mesh often end up with two networks; Sonos then splits across them.
What to do: Put the Virgin hub into modem mode and let the mesh run the network.
If it simply won't play nicely
- Wire one Sonos speaker to the router — The rest of the system then follows it, and drop-outs usually stop.
- A mesh system with wired backhaul — Keeps every speaker on one network with no second name to get lost on.
