Features
Works with
- Any broadband connection with an Ethernet handoff; the 2.5GbE combo port works as WAN or LAN
- Mesh-expandable with Synology WRX560, RT2600ac and MR2200ac satellites
- Standards-based Wi-Fi 6/802.11ax and 802.11ac/n/g/a client support; IPv6 capable
Is it for you?
Synology's tri-band AX6600-class Wi-Fi 6 router with a 2.5GbE multi-gig WAN/LAN port, three 1GbE LAN ports, a quad-core 1.8GHz CPU and 1GB of RAM, running Synology Router Manager (SRM) with Safe Access parental controls, five separate networks with 15 SSIDs, VLAN and VPN Plus.
Choose it if these matter
- Safe Access parental controls are built into the router's own operating system: no subscription, per-child profiles, screen-time schedules and quotas, and per-device web-category filtering with HTTPS filtering via DNS
- Five configurable networks and 15 SSIDs let a household separate kids, IoT, work and guests with distinct firewall profiles and VLANs
- Expands into a mesh with Synology WRX560 or RT2600ac satellites instead of being replaced
Skip it if these rule it out
- No Amazon listing is linked from Synology's own product page for this model, so buying it means searching for the exact model number
- Only three 1GbE LAN ports and no additional multi-gig LAN ports beyond the single combo 2.5GbE port
- Parental-control reporting and SRM management happen in Synology's own web interface rather than a dedicated mobile app for controls
- Synology does not link this model on Amazon, so the price and availability must be checked at retail
Good for: Gaming · Streaming · Large homes · Home office · Lots of smart devices · Multi-gig internet

- What differs
- The tri-band AX6600-class Wi-Fi 6 router with 2.5GbE WAN/LAN described here.
- Best for
- Whole-home parental control and mesh-capable Wi-Fi 6 routing.
Watch out
- RT6600ax is Synology's own router; it is not an add-on for a third-party router and does not need one
- WRX560 and MR2200ac are Synology mesh satellites that extend an RT6600ax, not standalone replacements for it
- RT2600ac is the older dual-band Wi-Fi 5 router, not this model
