WiFi 6E mesh has settled into its sweet spot — prices have dropped, firmware is mature, and both of these kits represent solid value compared to their launch prices. The Deco X90 is the value play at roughly $300 for a two-node kit. The Orbi RBK863S is pricier but consistently places near the top of throughput charts.
TP-Link Deco X90
For most homes, the Deco X90 is the smarter buy. You get WiFi 6E coverage, free HomeCare security, and a lower price. The Orbi RBK863S earns its premium only if you need maximum throughput and are willing to pay for NETGEAR Armor.
Specs Comparison
| Spec | TP-Link Deco X90 | NETGEAR Orbi RBK863S |
|---|---|---|
| WiFi Standard | WiFi 6E (AXE6600) | WiFi 6E (AXE11000) |
| 6 GHz Throughput | ~850 Mbps (close range) | ~1100 Mbps (close range) |
| Security Suite | HomeCare (free) | Armor (~$150/yr) |
| 2-node kit price | ~$300 | ~$500 |
| Coverage per node | Up to 3000 sq ft | Up to 3000 sq ft |
| Processor (base) | MediaTek MT7986 quad-core | Quad-core 2.2 GHz |
Performance Comparison
In SmallNetBuilder's WiFi 6E mesh tests, the Orbi RBK863S measured about 1.1 Gbps on the 6 GHz band at close range — one of the highest scores in the category. The Deco X90 came in around 850 Mbps under similar conditions. The gap closes noticeably at range.
The Orbi's dedicated backhaul band means client radios aren't competing with inter-node traffic. The X90 also uses tri-band, but its backhaul implementation is less aggressive.
Coverage and Node Design
Both are rated for 3,000 sq ft per node. Real-world reports put them close together in open-plan homes, with the Orbi pulling ahead in homes with more construction obstacles.
The Deco X90's tower form factor fits in tighter spaces. The Orbi is notably large — it's a conversation piece whether you want it to be or not.
Security and Cost of Ownership
TP-Link HomeCare on the X90 is completely free — antivirus, malware protection, parental controls, QoS. NETGEAR Armor on the Orbi runs about $150/year after the trial. That's a $750 cost difference over five years.
Both systems handle firmware updates automatically. TP-Link has been responsive on security patches; NETGEAR has a longer track record.
Setup and Long-Term Use
Both systems configure quickly — TP-Link's Deco app and NETGEAR's Orbi app walk you through setup in under 10 minutes. Adding nodes later is equally straightforward on both platforms.
Long-term, the Deco X90 benefits from being a mature product with stable firmware. The Orbi RBK863S is also well-regarded for reliability, with users on r/HomeNetworking running the same kit for years without major issues.

FAQ
Is WiFi 6E still worth buying now that WiFi 7 routers are available?
At current prices, yes. WiFi 6E mesh kits have dropped significantly, and the real-world performance gap vs WiFi 7 is small for most users. WiFi 7 is worth the premium mainly if you have wired backhaul or WiFi 7 client devices.
Does the Deco X90 support wired backhaul?
Yes. Plug an Ethernet cable between nodes and the Deco app detects it automatically, switching to wired backhaul.
