2026 verdict
The NETGEAR Nighthawk RS700S outguns the TP-Link Archer AX21 on every spec sheet number, but the TP-Link Archer AX21 still takes this router comparison on price and warranty length.
The Nighthawk RS700S is a tri-band Wi-Fi 7 router with a 10 Gbps internet port and a 10 Gbps LAN port, coverage for large homes and up to 200 devices, but it carries no mesh standard at all and sits at the very top of the category on cost. The TP-Link Archer AX21 is a dual-band Wi-Fi 6 router with four Gigabit LAN ports, EasyMesh and OneMesh support, a VPN client and server including WireGuard, and a two year warranty against one. Buy the TP-Link Archer AX21 to replace a weak ISP gateway on a budget with room to add mesh nodes later; buy the NETGEAR Nighthawk RS700S only if one powerful, non-expandable Wi-Fi 7 router in the middle of the house is the whole plan.

What the differences mean
Wi-Fi generation
The NETGEAR Nighthawk RS700S is a tri-band Wi-Fi 7 router with 320 MHz channels on 6 GHz. The TP-Link Archer AX21 is a dual-band Wi-Fi 6 router with no 6 GHz band at all, a full generation behind.
Mesh expansion
The TP-Link Archer AX21 supports EasyMesh and TP-Link OneMesh, so extra nodes can join later. The NETGEAR Nighthawk RS700S supports no mesh standard, so a second unit can never extend it wirelessly.
Ports
The NETGEAR Nighthawk RS700S has a 10 Gbps internet port, a 10 Gbps LAN port and a USB 3.0 port for network storage. The TP-Link Archer AX21 has Gigabit ports only and no USB port at all.
VPN client
The TP-Link Archer AX21 runs a VPN client, including WireGuard, alongside its VPN server. The NETGEAR Nighthawk RS700S only runs a VPN server, with no client of its own for a commercial VPN provider.
Warranty
The TP-Link Archer AX21 carries a two year warranty. The NETGEAR Nighthawk RS700S carries one, half as long.
Price
The TP-Link Archer AX21 is the far more affordable of the two. The NETGEAR Nighthawk RS700S sits at the top of the router category on cost, which buys its extra generation of Wi-Fi and its multi-gig ports.
Which one to buy if
- you will need to expand coverage later with extra nodes
The TP-Link Archer AX21 supports EasyMesh and OneMesh; the NETGEAR Nighthawk RS700S supports no mesh standard at all.
- you have a multi-gig internet plan and want the fastest possible single router
Its 10 Gbps internet and LAN ports and tri-band Wi-Fi 7 radios outrun anything the TP-Link Archer AX21 offers.
- you want a VPN client built into the router, not just a server
The TP-Link Archer AX21 runs a VPN client including WireGuard; the NETGEAR Nighthawk RS700S only runs a VPN server.
- budget and warranty length are the deciding factors
It costs far less and carries a two year warranty against one for the NETGEAR Nighthawk RS700S.

What owners say
Owners of both routers describe a dramatic coverage upgrade over whatever they replaced. NETGEAR Nighthawk RS700S owners moving from older Nighthawk or Wi-Fi 5 gear report their throughput doubling or better, and several say a single unit finally reaches corners of a large home that used to need an extender, though a minority in bigger, open floor plans still found the signal fell short and sent the router back. TP-Link Archer AX21 owners bought it mainly to replace a weak ISP gateway, and repeatedly call setup through the Tether app a matter of minutes, with internet reaching rooms and floors the old router missed; their complaints are minor and mostly about software, an app more limited than rival brands and some trouble with the router's Alexa skill.
