The eight checks

What we check	Rating	Points
Works on 2.4 GHz Long-range band available if the living room is far from the router.	Excellent	14/14
Works on 5 GHz Uses the faster band for home-theatre audio.	Supported	12/14
Modern Wi-Fi security Fine with current router security.	Good	10/12
Happy on mesh Wi-Fi Fixed under the TV, so it holds one box steadily.	Very good	14/16
Works on a guest network Unsupported on guest networks.	Poor	3/8
Survives a plug-in extender A second network name breaks grouping with other rooms.	Issues possible	5/8
Doesn't depend on chatty discovery Needs to see the rest of the Sonos system continuously.	Significant dependency	12/16
Easy to fix when it goes wrong Easy to wire, which is the real fix — but few people think of it.	Medium	11/12
WiFiXpert Compatibility Score		81/100

What usually goes wrong

Surrounds or a sub drop out mid-film, or the room disappears while grouped.

Free things to try, in this order

1
Run a network cable from the router or a mesh box to the Beam — it is the single best Sonos fix.
2
Keep every speaker on one Wi-Fi name.
3
Remove any extender making a second name.
4
Restart the Beam before the router.

Before you buy anything

A £10 cable first. Only then consider a mesh box behind the TV.

Answers about this gadget

Sonos Beam (Gen 2) — smart-home gadget keeps going offline

What it needs from your network

Living-room Sonos unit that can be wired, which is the most reliable fix available to a Sonos owner.

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

Sky: Sky's hub gives few settings, so there is little to change when surrounds drop mid-film.
What to do: Wire the Beam to the hub or a mesh box instead of adjusting settings.

If it simply won't play nicely

A network cable to the Beam — Ends most home-theatre drop-outs outright.
