TP-Link Archer BE550 vs NETGEAR Nighthawk RS300
Choose the Archer BE550 when several wired devices need 2.5GbE — five multi-gig ports beat two. Choose the Nighthawk RS300 only when already invested in NETGEAR management or its Armor trial terms suit you. Wireless classes (BE9300 both) do not separate them.
Ports decide, not the BE number
Both are tri-band BE9300-class routers with 6 GHz and a 2.5GbE WAN. The difference is the LAN side: the BE550 gives four 2.5GbE LAN ports while the RS300 gives two 2.5GbE plus two gigabit. A NAS, desktop, and console setup can outgrow two fast ports quickly.
Neither lists 10GbE, so both top out at 2.5 Gbps plans. On a 2 Gbps+ plan, both are the wrong tier — step up to 10GbE hardware instead.
Software and subscriptions
TP-Link bundles HomeShield with a free basic tier; NETGEAR pushes Armor as an optional paid layer after trial. If you never pay for router subscriptions, the BE550's free tier is the calmer ownership path.
