Pros & Cons

Pros

  • ✓ Tri-band Wi-Fi 6 with up to 6.6 Gbps combined wireless throughput
  • ✓ 2.5GbE port works as WAN for multi-gig ISPs or as an extra LAN port
  • ✓ 5.9 GHz spectrum support adds extra 80 MHz and 160 MHz channels
  • ✓ Up to 5 separate networks to isolate IoT, guest and work devices
  • ✓ Built-in VPN server with site-to-site tunneling and remote desktop

Cons

  • ✗ Wi-Fi 6 only, with no 6 GHz band as on Wi-Fi 6E or Wi-Fi 7 routers
  • ✗ Single 2.5GbE port, so multi-gig WAN and multi-gig LAN can't run at once
  • ✗ Segmentation capped at 5 separate networks
  • ✗ Top speeds need clients that support 160 MHz channels

Manufacturer description

The Synology RT6600ax is a tri-band Wi-Fi 6 router for households and home offices that need more control than a typical ISP gateway gives you. It has three radios with up to 6.6 Gbps of combined wireless throughput. Support for the expanded 5.9 GHz spectrum adds extra 80 MHz and 160 MHz channels, which leaves fast clients more room on crowded networks. On the wired side, a 2.5GbE port lets you use multi-gig internet plans. If your ISP tops out below that, you can set the port as a LAN port for a fast NAS or workstation. The RT6600ax runs Synology Router Manager (SRM). You can create up to 5…

Frequently Asked Questions

How fast is the Synology RT6600ax?

Synology rates the RT6600ax at up to 6.6 Gbps of combined wireless throughput across its three Wi-Fi 6 radios. Real speeds for each device depend on the client's Wi-Fi capabilities and channel width.

Can the RT6600ax handle internet plans faster than 1 Gbps?

Yes. The 2.5GbE WAN port is built for multi-gig ISPs. If you don't need it for WAN, you can set it up as a 2.5GbE LAN port instead.

Can I put smart home devices on a separate network?

Yes. You can create and define up to 5 separate networks, so vulnerable devices such as IoT gadgets stay away from your main computers and phones.

Does the RT6600ax support Wi-Fi 6E or the 6 GHz band?

No. It is a Wi-Fi 6 router. It adds 5.9 GHz spectrum support, which opens extra 80 MHz and 160 MHz channels, but it does not run on the 6 GHz band.

Can I use the RT6600ax as a VPN server?

Yes. Synology Router Manager includes a VPN server with remote desktop access and site-to-site tunneling. Check Synology's product listing for the current list of supported VPN protocols and the warranty terms.
