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.
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.
