TP-Link Deco
Good value mesh with plenty of settings — and a few separate networks that catch people out.

WiFiXpert Hardware Index · ranked 4 of 8
TP-LinkEvidence 100%Methodology v1.0
What's good
- Cheaper per unit than most rivals
- More settings to work with when something misbehaves
- Wide model range
What isn't
- The separate IoT network is the single most common cause of 'my app can't find it'
- Some models trim the background chatter speakers rely on
- Quality varies across the range
The facts
- Wi-Fi names and bands
- One Wi-Fi name by default; separate IoT and guest networks can be switched on.
- Wi-Fi generation
- Model dependent — the Deco range spans several generations; check the model number.
- Ethernet
- Ethernet sockets on each unit; the number varies by model.
- Wired backhaul
- Wired backhaul supported.
- Security
- Modern encryption; some models default to a mixed mode for older gadgets.
- App and settings
- App led, with more settings exposed than most rivals.
- Subscription
- Core Wi-Fi works without paying. HomeShield's better security and controls are a paid add-on.
